5 Safe & Promising Supplements for Glioblastoma

on Mar 13, 2023| Modified on Jul 22, 2023
Glioblastoma Supplements

I knew someone who recently passed away from Glioblastoma Multiforme, a fast-growing and aggressive brain tumor. I suggested some things to his wife, but she chose to believe their doctor's prognosis that her husband would live another five years. However, I urged her to do some research because typically this type of cancer has a one-year survival rate after diagnosis. They didn't ask me any questions about it and unfortunately, her husband passed away about a year later.

It's important to note that this cancer is very aggressive and typically has a poor one-year survival rate. 

While the five below supplements cannot cure the cancer, studies have shown they can potentially increase survival time. One of the supplements was even shown to do so in a human study with just 20 mg/day.

1. Melatonin

The first supplement I would like to discuss is Melatonin. Melatonin has the ability to cross the blood-brain barrier (BBB), which is useful and needed in this case.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3001209/#:~:text=One important characteristic of melatonin, than exist in the blood.

A relevant quote from the above link confirms that melatonin crosses the BBB:

One important characteristic of melatonin is its permeability into the brain. It readily passes through the blood-brain-barrier and accumulates in the central nervous system at substantially higher levels than exist in the blood. 

Melatonin also has anticancer effects, as discussed in this next link :

https://cmbl.biomedcentral.com/articles/10.1186/s11658-022-00375

Here is a very relevant quote from the above link describing some of the anticancer effects of melatonin:

Moreover, the evidence is compelling that melatonin has a variety of anti-cancer effects, such as its inhibition of cancer cell viability, proliferation, progression, and metastasis or even inhibition of cancer initiation [3,4].

Melatonin is also useful for use in people with GBM and also has synergy with temozolomide ( an antineoplastic used for GBM treatment) as discussed here:

Glioblastoma is the most prevalent primary tumor of brain. Furthermore, glioblastoma is a highly aggressive and lethal type of cancer; the average of life expectancy is reported to be less than 1 year after it is diagnosed. Because of the difficulty with complete surgical resection and high resistance of glioblastoma to existing chemotherapy agents, treatment of these patients remains exceedingly complicated. Therefore, there is an urgent need for developing unconventional therapeutic strategies in the treatment of patients with malignant glioblastoma. In the past few years, different investigations have shown the existence of stem cell-like cells in solid tumors involving malignant glioblastomas [75]. Stem cell-like cells are important built-in multidrug-resistant and pluripotent cells that commonly develop drug resistance and continue to proliferative after a chemotherapy regimen. Accordingly, the therapeutic approaches that cannot eradicate the brain tumor stem cells (BTSCs) are expected to be unsuccessful. While these treatments may be successful for killing an appreciable number of tumor cells and causing a transitory regression, they fail to alter cancer relapse [76]. For the purpose of achieving a persistent long-lasting treatment of glioblastoma patients, it is a requirement to discover and develop novel therapeutic strategies for targeting both BTSCs and tumor bulk.

Martin and colleagues [77] investigated the properties of melatonin and its combination with chemotherapeutic agents on these multi-drug resistant brain tumor stem cells. Results showed that melatonin and chemotherapeutic drugs in combination induced a remarkable synergistic toxicity against BTSCs and malignant A172 glioma cells. Co-treatment with temozolomide as current agent for remission of malignant glioma with melatonin, significantly correlated with down-regulated expression of ABCG2/BCRP and subsequent inhibition of ABC transporter functions. In fact, melatonin significantly elevated DNA methylation of the promoter of ABCG2/BCRP; thus, the expression properties and function of ABCG2/BCRP were prohibited due to the preincubation melatonin with a DNA methyltransferase inhibitor (DNMTi). Hence, their findings highlight a potent association between the decrease of ABCG2/BCRP activities and the synergistic toxicity of melatonin and therapeutic agents. By inducing DNA methylation in proto-oncogenes, melatonin also could be considered as a promising chemical for defeating multi-drug resistance in malignant glioblastomas, and improving the effectiveness of current chemotherapeutic regimens.

Melatonin also synergizes with other drugs used to fight GBM as discussed here:

https://www.nature.com/articles/bjc2013188

Here is a relevant quote :

Data presented here showed that combination of melatonin with chemotherapeutics has a synergistic toxic effect both in BTSC and glioblastoma cell lines. Thus, melatonin increases toxicity of several drugs including temozolomide, current treatment for malignant glioblastoma.

The fact that melatonin can increase the toxicity toward GBM may allow for lower dosing of these chemotherapeutics in some cases where that would be desirable for certain patients who are reacting negatively to the anticancer medication.

Melatonin can also help reduce the damage caused to the body by these chemotherapeutic and radiotherapy agents, which would be very useful in reducing unwanted chemo side effects as well as fight multidrug resistance, inhibit stem-like cell proliferation in GBM and decreasing the viability and inhibiting the proliferation of glioblastoma cells as discussed here in this 2021 review:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8123278/

Here is a relevant quote from the review:

Glioma stem-like cells are subpopulation in glioblastoma, they play a crucial role in the tumor growth maintenance and recurrence [152,153,154], and promote self-renewing capacity and tumor propagation [155,156,157]. Melatonin showed an anticancer effect against glioblastoma, and it was also reported to overcome the multi-drug resistance in glioblastoma treatment [158,159,160]. Sung et al. recently have investigated the impact of combination of melatonin with vorinostat on the expression of transcription factor EB and apoptosis in glioblastoma cells and glioma cancer stem cells. The expression of transcription factor EB, which needs oligomerization to regulate transcription, was reported to be increased in glioblastoma. The combination of vorinostat and melatonin induce a downregulation of the transcription factor EB and oligomerization, which increased apoptosis related gens, hence, cells apoptosis was activated [161]. In another study, Chen et al. have studied the roles of melatonin and the associated mechanisms against glioblastoma stem-like cells. Their results demonstrated that melatonin altered the glioblastoma stem-like cells biology and inhibited glioblastoma stem-like cells proliferation. Moreover, melatonin showed to alter the transcription factors profile inhibiting the initiation and propagation of tumor. In addition to the impairment of EZH2–STAT3 interaction and EZH2 S21 phosphorylation, melatonin has multiple roles in attenuating several key signals related to survival and self-renewal in glioblastoma stem-like cells [158]. Lai et al. have studied the microenvironment of glioma investigating the correlation of melatonin treatment and molecular markers in glioblastoma multiform including SIRT1, CCL2, ICAM-1, and VCAM-1. Their results showed melatonin administration increased the expression of SIRT1, which inhibit the growth and proliferation of glioma cells [162]. In another recent study, Fernandez-Gil et al. have explored whether treatment with melatonin can restore the oxidative phosphorylation after metabolic switch to glycolysis in glioblastoma cells. The results showed that melatonin significantly decreased the viability and inhibited the proliferation of glioblastoma cells. Besides, it modulates a metabolic shift from glycolysis to oxidative phosphorylation, which lead to a reduction in the malignant properties of glioblastoma cells [163]. Additionally, it was reported that the melatonin antitumor effect can be through suppression of the EZH2-NOTCH1 signaling axis in glioblastoma stem-like cells [164]. Moreover, several studies have shown the melatonin impact on glioblastoma cells via enhancing apoptosis and inhibiting cell migration and invasion [165,166,167]. 

Lastly, regarding melatonin, in one small study, it increased the survival time of glioblastoma patients as discussed here:

https://www.karger.com/Article/Abstract/227533

Here is a relevant quote from the study:

At present, no chemotherapy has appeared to influence its prognosis. On the other hand, recent advances in brain tumor biology have suggested that brain tumor growth is at least in part under a neuroendocrine control, mainly realized by opioid peptides and pineal substances. On this basis, we evaluated the influence of a concomitant administration of the pineal hormone melatonin (MLT) in patients with glioblastoma treated with radical or adjuvant radiotherapy (RT). The study included 30 patients with glioblastoma, who were randomized to receive RT alone (60 Gy) or RT plus MLT (20 mg/daily orally) until disease progression. Both the survival curve and the percent of survival at 1 year were significantly higher in patients treated with RT plus MLT than in those receiving RT alone (6/14 vs. 1/16). Moreover, RT or steroid therapy-related toxicities were lower in patients concomitantly treated with MLT. This preliminary study suggests that a radioneuroendocrine approach with RT plus the pineal hormone MLT may prolong the survival time and improve the quality of life of patients affected by glioblastoma.

The study mentioned above was conducted in 1996, which is 27 years ago. Surprisingly, there have been no follow-up studies on Glioblastoma Multiforme patients using higher doses of melatonin, despite the clear benefits observed in the study even with just 20 mg/day. This raises the question of why further studies using higher doses of melatonin were not conducted, especially considering its excellent safety profile that surpasses other treatments used for GBM. Additionally, melatonin is affordable and easily accessible. It's unclear if this is simply an unintentional oversight or if there are other factors at play.

To help you understand the potential benefits of higher doses of melatonin, a study conducted on Parkinson's disease patients administered 50 mg of melatonin per day. The results showed that this dose was able to reduce levels of oxidative stress, which is a significant contributor to disease progression, to similar levels found in healthy individuals.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8545577/

A relevant study quote :

At baseline, plasma levels of lipoperoxides, nitric oxide metabolites, and carbonyl groups in proteins were significantly higher in PD patients than in the healthy control group (Figures 1(a)–1(c), respectively). Conversely, the plasma activity of catalase was lower in the healthy control group than in PD patients (Figure 1(d)). These data suggest the existence of an active, persistent oxidative stress in PD. After three months of treatment with melatonin, the levels of lipoperoxides, nitric oxide metabolites, and carbonyl groups in proteins were lower than in the placebo group and were statistically similar to the levels of healthy controls. The activity of catalase was increased with the treatment with melatonin at levels similar to the control group.

To treat ALS patients, melatonin was administered at a dosage of 300 mg per day for up to two years in the form of suppositories. This is noteworthy because melatonin has poor bioavailability, estimated to be between 3% to 15%. Suppository delivery is believed to have significantly higher bioavailability, making it a more effective method of administering melatonin.

https://onlinelibrary.wiley.com/doi/10.1111/j.1600-079X.2006.00377.x

Here is a relevant study quote:

' We found that melatonin attenuates glutamate-induced cell death of cultured motoneurons. In SOD1G93A-transgenic mice, high-dose oral melatonin delayed disease progression and extended survival. In a clinical safety study, chronic high-dose (300 mg/day) rectal melatonin was well tolerated during an observation period of up to 2 yr. Importantly, circulating serum protein carbonyls, which provide a surrogate marker for oxidative stress, were elevated in ALS patients, but were normalized to control values by melatonin treatment. This combination of preclinical effectiveness and proven safety in humans suggests that high-dose melatonin is suitable for clinical trials aimed at neuroprotection through antioxidation in ALS. '

The ALS study mentioned earlier, conducted in 2006, showed the safety of using 300 mg/day of melatonin for up to 2 years.

Finally, it is worth noting that Dr. Shallenberger has reported using 360 mg/day in stage 4 cancer patients in this video: https://youtu.be/Roh4lQXneQg

2. Berberine

Like melatonin, Berberine can cross the blood-brain barrier and has a good safety profile surpassing currently available Glioblastoma Multiforme treatments. While there is less information available about the relationship between Berberine and cancer compared to melatonin, recent studies have demonstrated that Berberine has multiple anti-cancer effects. Moreover, Berberine has been shown to work synergistically with certain chemotherapeutic agents, as discussed here:

https://e-century.us/files/ijcem/11/12/ijcem0070566.pdf

Here is a relevant quote :

Results: MTT assay results showed berberine inhibited cell proliferation of human breast cancer cell lines MCF-7 and MDA-MB-231 in a dose-dependent manner. Co-treatment with berberine and cisplatin or 5-Fu significantly inhibited cell viability of MCF-7 cells than that with berberine or chemotherapeutic drugs alone. Western blotting results demonstrated that the level of cleaved caspase-3 obviously increased in MCF-7 cells treated with berberine in combination with cisplatin than the monotherapy alone. Moreover, the ratio of Bax/Bcl-2 was upregulated in the group of combination therapy with berberine and cisplatin than that with monotherapy alone. Transwell assay data showed that berberine in combination with cisplatin significantly decreased cell migratory ability of MCF-7 cells. Conclusion: Berberine showed synergistic effects in combination with chemotherapeutic drugs to remarkably inhibit cell proliferation and suppress cell migration of breast cancer cells. 

This next review discusses some of the anticancer effects of berberine:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6996556/

Here is a relevant quote :

'The traditional Chinese medicine BBR has been shown to affect cell cycle, cell apoptosis, cell autophagy, and the tumor microenvironment. BBR has also been shown to exert anti-inflammatory and antioxidant effects. Tumor immunotherapy is a hotspot for tumor therapy in recent years, immune-suppressants such as PD-1/PD-L1 suppressants have emerged one after another. However, it is difficult to be widely used in clinic due to their high prices. BBR as an effective immunomodulator and a kind of cheap Chinese traditional drug, is expected to be widely used in clinical practice as an ideal drug for immunotherapy.

As studies showed, BBR exerted its role on autophagy through different mechanisms. In several cancer cells, BBR inhibited cell proliferation by inducing autophagy and also reversed drug resistance by regulating cell autophagy.45,46 However, in mature adipocytes, BBR maintained the cellular homeostasis by inhibiting autophagy.47 Studies showed that autophagy plays an important role in maintaining a stable intracellular environment.92,93 We inferred that autophagy plays different roles in cells. On the one hand, tumor cells evaded apoptosis through decreasing autophagy level; therefore, BBR treatment up-regulated autophagy and led to cancer cell death. On the other hand, BBR treatment lowered the original high level of autophagy in mature adipocytes to contribute to maintenance of a stable intracellular environment. Regulation of BBR on autophagy is complicated; therefore, studies are needed to make further progress on regulation of BBR on autophagy. 

I know, anticancer effects definitely, but what about glioblastoma? To that point, this 2015 study points out one of the ways that berberine may be effective against glioblastoma :

https://aacrjournals.org/mct/article/14/2/355/175585/Berberine-Induces-Senescence-of-Human-Glioblastoma

Here is an important quote from the link :

Our results showed that berberine possesses a potent antitumor effect against some glioblastoma cells. It can effectively induce glioblastoma cells to undergo cellular senescence. Interestingly, while berberine has been reported to exert its cytotoxic effect by inducing apoptosis in numerous types of cancer cells (13,16,18,19), none of the glioblastoma cell lines we tested in this study showed signs of increased apoptosis in response to berberine treatment. Therefore, induction of cellular senescence (loss of a cell's power of division and growth) is probably the major mechanism by which berberine exerts its antitumor effect against glioblastoma cells. Indeed, induction of senescence has recently been recognized to be an important therapeutic strategy for various types of cancer (25,26). We further showed that the level of EGFR was greatly reduced in berberine-treated cells and that pharmacologic inhibition or RNA interference of EGFR similarly induced cellular senescence of glioblastoma cells. Accompanying the downregulation of EGFR, the RAF-MEK–ERK signaling pathway downstream of EGFR was remarkably inhibited in berberine-treated cells. Because the cellular senescence induced by berberine could be rescued by introduction of constitutive active MKK, we conclude that the induction of cellular senescence in berberine-treated glioblastoma cells is likely mediated by the downregulation of the EGFR–RAF–MEK–ERK pathway. Because EGFR amplification is characteristic of classic subtype of glioblastoma multiforme (GBM) and sustains the proliferation of GBM (27–29), the effective downregulation of EGFR by berberine suggests that use of berberine could be considered in the treatment of GBM.

To further delve into berberine and glioblastoma, this 2022 abstract looks at various methods of action of berberine that work against glioblastoma and reaches the conclusion that berberine is a good choice for glioblastoma multiforme :

https://pubmed.ncbi.nlm.nih.gov/35209812/

Here is a relevant quote :

The most typical malignant brain tumor, glioblastoma multiforme (GBM), seems to have a grim outcome, despite the intensive multi-modality interventions. Literature suggests that biologically active phytomolecules may exert anticancer properties by regulating several signaling pathways. Berberine, an isoquinoline alkaloid, has various pharmacological applications to combat severe diseases like cancer. Mechanistically, it inhibits cell proliferation and invasion, suppresses tumor angiogenesis, and induces cell apoptosis. The antitumoral effect of berberine in GBM is increasingly recognized. This review sheds new light on the regulatory signaling mechanisms of berberine in various cancers, proposing its potential role as a therapeutic agent for GBM.

Unfortunately, the full study for the above link is behind a paywall.

Lastly, this final berberine/glioblastoma study goes even deeper into the methods of action of berberine against glioblastoma :

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9583234/

Here is a relevant quote from the study :

Berberine significantly inhibited the proliferation of human glioma U-87 cells, and induced apoptosis in the U-87 and LN229 cells by downregulating Bcl-2, and upregulating Bax and caspase-3. In addition, berberine also inhibited migration and invasion of the glioma cells. Furthermore, berberine exerted its effects on the proliferation, migration, invasion, and apoptosis of glioma cells by inhibiting the TGF-β1/SMAD2/3 signaling pathway, and exogenous TGF-β abrogated the pro-apoptotic and anti-oncogenic effects of berberine.

Conclusions:

Berberine inhibits glioma progression by targeting the TGF-β1/SMAD2/3 signaling pathway.

In summary, both Melatonin and Berberine have excellent safety profiles and can be discussed with your doctor or oncologist. I have already mentioned the dosing of Melatonin previously.

Regarding Berberine dosage, human studies have shown that a dosage of 1500 mg per day, divided into three doses of 500 mg each (taken after breakfast, lunch, and dinner), has demonstrated efficacy and safety in individuals with diabetes, as discussed here:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2410097/

Here is a relevant quote from the study of berberine in people with type two diabetes:

In study A, 36 adults with newly diagnosed type 2 diabetes were randomly assigned to treatment with berberine or metformin (0.5 g t.i.d.) in a 3-month trial. The hypoglycemic effect of berberine was similar to that of metformin. Significant decreases in hemoglobin A1c (HbA1c; from 9.5% ± 0.5% to 7.5% ± 0.4%, P<0.01), fasting blood glucose (FBG; from 10.6 ± 0.9 mmol/L to 6.9 ± 0.5 mmol/L, P<0.01), postprandial blood glucose (PBG; from 19.8 ± 1.7 to 11.1 ± 0.9 mmol/L, P<0.01) and plasma triglycerides (from 1.13 ± 0.13 mmol/L to 0.89 ± 0.03 mmol/L, P<0.05) were observed in the berberine group. In study B, 48 adults with poorly controlled type 2 diabetes were treated supplemented with berberine in a 3-month trial. Berberine acted by lowering FBG and PBG from one week to the end of the trial. HbA1c decreased from 8.1% ± 0.2% to 7.3% ± 0.3% (P<0.001). Fasting plasma insulin and HOMA-IR were reduced by 28.1% and 44.7% (P<0.001), respectively. Total cholesterol and low-density lipoprotein cholesterol (LDL-C) were decreased significantly as well. 

One of the most commonly reported side effects of Berberine in the study mentioned above is a gastrointestinal disturbance. Taking Berberine after a meal may help prevent gastrointestinal upset.

Finally, this study shows that Berberine and Melatonin have synergy together in fighting lung cancer cells:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4823085/

Here are some relevant quotes from the study :

Treatment with melatonin effectively increased the berberine-mediated inhibitions of cell proliferation, colony formation and cell migration, thereby enhancing the sensitivities of lung cancer cells to berberine. Melatonin also markedly increased apoptosis induced by berberine. Further mechanism study showed that melatonin promoted the cleavage of caspse-9 and PARP, enhanced the inhibition of Bcl2, and triggered the releasing of cytochrome C (Cyto C), thereby increasing the berberine-induced apoptosis. Melatonin also enhanced the berberine-mediated inhibition of telomerase reverses transcriptase (hTERT) by down-regulating the expression of AP-2β and its binding on hTERT promoter. Moreover, melatonin enhanced the berberine-mediated inhibition of cyclooxygenase 2 (COX-2) by inhibiting the nuclear translocation of NF-κB and its binding on COX-2 promoter. Melatonin also increased the berberine-mediated inhibition of the phosphorylated Akt and ERK. Collectively, our results demonstrated that melatonin enhanced the antitumor activity of berberine by activating caspase/Cyto C and inhibiting AP-2β/hTERT, NF-κB/COX-2 and Akt/ERK signaling pathways.

In summary, melatonin sensitized NSCLC cells to berberine and enhanced the growth inhibitory effect of berberine by simultaneously targeting caspase/cytochrome C, AP-2β/hTERT, NF-kB/COX-2, Akt/ERK signaling pathways. These findings provide new insights into understanding the molecular mechanisms by which melatonin sensitizes NSCLC cells to berberine treatment, and suggest some clues for the development of new therapeutic strategies in human lung cancer therapy.

3. Vitamin D

This 2022 review delves into how vitamin D affects Glioblastoma (GBM) :

https://www.laboratoryinvestigation.org/article/S0023-6837(22)00073-3/fulltext

The above study shows that vitamin D and its analogues have anti-tumor activity, increase vitamin D receptors (VDR), bind to these VDRs to regulate GBM at the cellular level, have antimigratory effects, increase the active form of vitamin D (1,25 (OH) 2D3 ), and increases Calcitriol levels. This cascade of effects works against GBM and other cancers.

Here is a relevant quote from the review :

' Vitamin D has largely been reported to promote cell cycle arrest and induce cell death to suppress tumor growth in glioblastoma. Glioblastoma cells treated with vitamin D have also shown reduced migratory and invasive phenotypes, and reduced stemness. It is worth noting that vitamin D analogs are able to produce similar inhibitory actions without causing adverse effects such as hypercalcemia in vivo. Upregulation of vitamin D receptors by vitamin D and its analogs may also play a role in enhancing its anti-tumor activity. '

This next Vitamin D study (July 2021) related to GBM shows that vitamin D has at least three important effects related to GBM. One is that serum vitamin D level is negatively correlated to GBM. So the higher the vitamin D level, the less risk of GBM. Two, vitamin D3 intake results in increased levels of Calcitriol, the most active form of vitamin D, and calcitriol works together with the GBM chemotherapy agent, Temozolomide to increase the susceptibility of GBM cells. Three, this interaction and targeting of calcitriol with stem-like cells allow Temozolomide to kill more of these stem-like cells and this is very important because GBM stem cells are what cause treatment resistance and recurrence. 
Here is a relevant study quote highlighting these important effects :

'  We further show that calcitriol synergizes with Temozolomide ex vivo to completely eliminate some GSC tumors. '

4. Andrographis

The following study highlights the current shortcomings of standard GBM treatment and then goes on to show how Andrographolide, an active component in Andrographis, works through multiple methods of action to induce cell cycle arrest, reduce cell migration and colony formation as well as stimulate the apoptosis pathway which is a programmed cell death pathway for removing aberrant cells such as GBM.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9572224/

A relevant study quote :

' This study successfully discovered the involvement of ERK1/2/c-Myc/p53 in the suppression of the DBTRG-05MG cell line via cell cycle arrest followed by the apoptosis signaling pathway following andrographolide treatment.'

This next study adds further confirmation to the antimigratory effects of Andrographolides in GBM. So this study highlights the antimetastatic effects of GBM :

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5739685/

Here is a relevant quote :

' In conclusion, the study demonstrated that andrographolide can inhibit the expression of CREB-DNA binding activity, MMP-2 expression and the inhibition of migration. Andrographolide also inhibits cell migration by increasing the phosphorylation of the ERK pathway. Thus, inhibition of cancer metastasis by andrographolide can provide crucial therapeutic protection against GBM. '

Certain Andrographis supplements are standardized to include a minimum 10% of Andrographolides such as this one :

https://www.amazon.com/NOW-Supplements-Andrographis-Standardized-Capsules/dp/B002VD8BEG/ref=sr_1_5?crid=2B0YS3U284OI1&keywords=andrographolide&qid=1688582239&sprefix=andrographolide,aps,155&sr=8-5

5. Boric Acid / Borax

The following study shows that boron compounds may be effective against GBM, especially the boron compound, boric acid(BA) and to a lesser extent, borax (BX).

 https://pubmed.ncbi.nlm.nih.gov/34293392/

Here is a relevant study quote :

' We finally observed that anticancer effect of BA and BX were associated with the BRAF/MAPK, PTEN and PI3K/AKT signaling pathways in respect of downregulatory manner. Especially, BA application was found more favorable because of its inhibitory effect on PIK3CA, PIK3R1, PTEN and RAF1 genes. In conclusion, our analysis indicated that boron compounds may be safe and promising for effective treatment of GB. '

Interestingly, both of these boron compounds, including boron itself, have shown benefit against arthritis. In the following study it is confirmed that Boron and boron compounds have direct tumoricidal activity against GBM and suggest that they may cross the blood-brain barrier (BBB).

https://www.researchgate.net/publication/331866350_Boron's_neurophysiological_effects_and_tumoricidal_activity_on_glioblastoma_cells_with_implications_for_clinical_treatment

Here is a relevant study quote :

' Nonetheless, the translational functionality of boron compounds is not limited to BNCT as many boron compounds possess direct tumoricidal activity and there is substantial evidence that certain certain boron compounds can cross the blood brain barrier. Moreover, boron containing compounds interfere with several tumorigenic pathways including intratumoral IGF-1 levels, molybdenum Fe-S containing flavin hydroxylases, glycolysis, Transient Receptor Potential (TRP) and STORE Operated Calcium Entry (SOCE) channels. '

This less recent second study also suggests that boron compounds are likely to be useful in other forms of cancer and while it also discusses pharmaceutical boron compounds against GBM, the first study specifically points at boric acid and borax as active against GBM.

Boric acid is available inexpensively over the counter in 99.9% purity.

So the addition of these three supplements and their different methods of action suggest potential synergy with melatonin and berberine which were discussed in the original article on GBM.

Summary

In conclusion, the five supplements are:

1. Melatonin

2. Berberine

3. Vitamin D

4. Andrographis

5. Boric Acid / Borax

These 5 supplements are worth discussing with your doctor or oncologist to determine if they could be helpful for you or your loved one. It's important to ensure that these supplements are safe to take alongside any other medications or treatments being administered.

It seems some anti fungal and anti parasites agent also possess anti cancer property, like ivermectin, mebendazole, fenbendazole......

The multitargeted drug ivermectin: from an antiparasitic agent to a repositioned cancer drug - PMC (nih.gov)

I recently run into a few studies that even methylene blue and borax also can do such things:

Tom,

That is an interesting regimen you are taking! Are you fighting cancer?

There are many molecules and supplements or alternatives that have anticancer effects. One of the characteristics that are needed for glioblastoma is the ability to cross the blood brain barrier (BBB). Ivermectin is not thought to have that capability, but mebendazole has shown that capability.

Another supplement with an excellent safety profile as well as the abilities to cross the BBB and have a negative impact on glioblastoma cells is Astaxanthin. Unfortunately studies are even more limited for it. Given the safety profile of astaxanthin, I would still consider higher dose astaxanthin if I had GBM.

It is one thing to say what you would do when you don't have GBM, but once you have confirmation from your doctor of a GBM diagnosis, I think rationale thinking goes out the window, at least temporarily, until you get past trying to wrap your head around the idea that you likely only have about a year to live.

Thank you for your feedback, Tom!

This is wrong info (regardless of what studies say) and you are giving people false hope. Studies like this are like a magician's "slight of hand"....they get you to look over here when the answer is actually in the other hand. My father died of glioblastoma 30 years ago. There is nothing new in this field. Actually, there are a few things that can stop all cancers and glios.....but it's not what you point your readers to...

smartsh,

I read your feedback about the glioblastoma post I wrote. I will reply to each point that you made.

You said, ' This is wrong info (regardless of what studies say) and you are giving people false hope.'

You are saying the studies are wrong, but offer nothing to substantiate your claim. By saying this you are essentially saying that all scientists and researchers involved in these studies are lying about their findings. Why would they do that and why are they all conspiring together to give out false hope to everyone who has glioblastoma? If this is the case, then are all scientific researchers also lying?

You said I am giving false hope by reporting these studies. All I am doing is reporting what these studies show. How is that giving false hope? I clearly stated what I wrote in the third paragraph,

'While the two below supplements cannot cure the cancer, studies have shown that they can potentially increase survival time. One of the supplements was even shown to do so in a human study with just 20 mg/day.'

That is not giving false hope, it is stating the facts of the study by a doctor/researcher, who dedicated his life to research of cancer and how melatonin helps fight it. Dr. Lissoni has 321 studies on PubMed and was the lead researcher in the majority of those studies. He has 450 publications and his studies date back to 1982 with his last study done in 2018 and his last article done in October 2022.

I don't know how you can denigrate a person of this caliber who has dedicated his life trying to not only fight cancer, but also try to find solutions to such a deadly disease and then you essentially call him a liar. What do you base your statement on? How is all of his research just "slight of hand?

Yes, this is what you said, ' Studies like this are like a magician's "slight of hand"....they get you to look over here when the answer is actually in the other hand.'

First this statement makes no sense, because there is no current answer for glioblastoma in any hand, that is a fact. Nobody with blastoma likes it, but there currently is no treatment that is effective. Your statement is offensive to every cancer researcher out there and especially to someone like Dr. Lissoni who has given his all to fight cancer in its many forms.

You said, ' My father died of glioblastoma 30 years ago.'

I am sorry for that, but we all have to go through that as part of life. It was hard for me to deal with my parents deaths, but we do it with the hope to see them in a better place and time.

You said, ' There is nothing new in this field. '

Definitely the therapeutics of glioblastoma has not advanced much in a beneficial way.

Lastly, you said, ' Actually, there are a few things that can stop all cancers and glios.....but it's not what you point your readers to... '

Well the world is holding their breath, waiting for you to share, " a few things that can stop all cancers and glios", and please include what you are basing that statement on.

As far as what I pointed to, I pointed to studies for a form of cancer that has an average life expectancy of 12 months and if you are lucky, maybe 14 months after diagnosis. If there is no cure, then the next best thing is trying to extend life if possible. If you are given a choice to die in a year with standard therapy or to try 2 supplements with standard therapy that could potentially add time beyond a year, I think the majority of people are going to opt for plan b, or you can share just share your few things that will cure all cancers and glios, as you said.

I think I covered all of your points.

I'm sad for your loss. But things have advanced with brain cancer. Look at Pablo Kelly in England (8 yr GBM survivor) And Logan Sneed. Both are using a Keto diet.

Boron/Borax/Boric Acid has a reputation for being antiarthritic, antiosteoporosis, and antifungal, among other health benefits that have been reported from its use, but the following study suggests that borax may have another untapped very significant health benefit as a fighter of brain cancer as discussed here :

https://www.sciencedirect.com/science/article/abs/pii/S0197018621001832?via=ihub

Here is a relevant quote from the study :

' We found that BA and BX led to a remarkable reduction in U-87MG cell viability in a concentration-dependent manner. We also found that boron compounds increased the total oxidative status and MDA levels along with the SOD and CAT enzyme activities and decreased total antioxidant capacity and GSH levels in U-87MG cells without inducing DNA damage. The cytokine levels of cancer cells were also altered. We verified the selectivity of the compounds using a normal cell line, HaCaT and found an exact opposite condition after treating HaCaT cells with BA and BX. BA applications were more effective than BX on U-87MG cell line in terms of increasing MDA levels, SOD and CAT enzyme activities, and decreasing Interleukin-1α, Interleukin-6 and Tumor necrosis factor- α (TNF- α) levels.

Especially, BA application was found more favorable because of its inhibitory effect on PIK3CA, PIK3R1, PTEN and RAF1 genes. In conclusion, our analysis indicated that boron compounds may be safe and promising for effective treatment of GB. '

So based on this study, Boric Acid appears to be more effective than Borax against Glioblastoma (brain cancer) cells although both showed anti-glioblastoma activity. Importantly, both showed more activity against the cancer cells than normal healthy cells. This is a problem often seen in chemotherapy where it is toxic to the cancer cells, but also too toxic to the normal cells resulting in unhealthful outcomes.

Like borax, boric acid is very inexpensive and readily available in what would be considered bulk amounts and some people prefer it to borax because it is more refined, whereas, borax is basically unrefined. Another reason why BA may be preferred over borax is because of the salt content of borax, which would be important for people who have to limit their salt intake.
For those who take boric acid (BA), they generally take a lower dose than would be needed for borax because BA has more boron in it than borax does. Where borax is approximately 11.34% boron, BA is approximately 17.48% boron.

In any case, I thought this is important information worth sharing with the EC community because Glioblastoma has an average survival time of 12 to 15 months after being diagnosed which gives a very good idea of how ineffective the current medical treatments are for this form of cancer. So BA seems worth considering if you have glioblastoma and seems worthy of mentioning with the other two supplements I discussed in the original article at the beginning of this page.

Re: Glioblastoma

Immediately start taking LDN and don't stop. If nothing else it slows progression of cancers, possibly puts it into a remission. You can even continue your treatments while taking LDN. Call a compounding pharmacy and ask names of the doctors who prescribe LDN. Make an appointment and get a prescription ($90/mo.) Anyone who has cancer of any type must take LDN indefinitely. Get LDN, do research later, you have no time to waste. Ldnreasearch trust is your source of the info about LDN. Make sure you don't live near cell towers, antennas etc.
