Magnesium's role in brain tumor treatmentPosterior reversible encephalopathy syndrome in an oncological normotensive patient: evidence for a pathogenic role of concomitant low magnesium serum levels and chemotherapy treatment.
Medium relevance to treatment outcomes
We explored the relationship between low magnesium levels and the development of posterior reversible encephalopathy syndrome (PRES) in a patient with advanced breast cancer. After treatment with diuretics and chemotherapy, this patient experienced serious neurological symptoms alongside low magnesium levels.
Following intravenous magnesium supplementation, the patient showed remarkable improvement within 18 hours. This suggests that low magnesium, potentially linked to her treatment regimens, might have played a role in her condition. Thus, monitoring magnesium levels could be crucial in cancer care.

Our study investigated the role of calcium, specifically vitamin B5 calcium, as an inhibitor of GOLPH3L in treating glioblastoma, a challenging form of brain tumor. We found that this compound may have potential in improving the effectiveness of radiotherapy, especially in cases resistant to standard treatments.
By targeting GOLPH3L, which plays a role in creating an immunosuppressive tumor environment, we were able to observe that the vitamin enhanced the antitumor immune response. This suggests that calcium treatment could help shift the balance from tumor-promoting factors to those that boost the body's natural defenses against cancer.
Notably, our research revealed that patients with glioblastoma who received vitamin B5 calcium alongside radiotherapy showed improved responses. However, it’s essential to mention that while the outcomes are promising, the specific efficacy of vitamin B5 calcium as a standalone treatment needs further exploration and validation in clinical settings.
In summary, we might be looking at an exciting new avenue where calcium treatment could help reshape the outcomes of glioblastoma therapy, particularly when equipped with the knowledge of how it interacts with tumor biology.

We investigated the role of T-type calcium channels in medulloblastoma, a particularly aggressive brain tumor that primarily affects children. The study utilized various methodologies, including bulk and single-cell RNA sequencing, to assess T-type calcium channel expression.
Our findings revealed that in more than 30% of patients, these calcium channels were upregulated. Notably, higher levels of T-type calcium channels were linked to poorer patient outcomes. We observed that inhibiting these channels with a drug called mibefradil significantly slowed down tumor growth, increased cell death, and reduced invasion.
Furthermore, through proteomic analysis, we mapped the signaling pathways affected by T-type calcium channel inhibition. Our results suggest that mibefradil not only acts on the calcium channels but also influences critical cancer pathways, confirming the potential of repurposing this existing drug for treating medulloblastoma. In animal models, oral administration of mibefradil led to a notable reduction in tumor size and extended survival.

We developed two unique animal models to explore how calcium influences tumor expansion, particularly in craniopharyngioma, a type of brain tumor notoriously known for invading the hypothalamus. This research aimed to understand whether the activity of neuroendocrine neurons impacts tumor growth.
During our study, we conducted a thorough high-throughput drug screening process and identified 74 compounds with significant antitumor properties. Among these, we found that the drug amlodipine besylate was particularly effective. Its administration led to tumor regression, possibly by influencing calcium transients and the chemical interactions between neurons and tumor cells.
Interestingly, we observed that manipulating neuroendocrine neuronal activity could either promote or slow down tumor growth, indicating that craniopharyngioma tumors can exploit these neurons to aid in their progression. Overall, these findings provide deeper insight into tumor biology and suggest potential pathways for developing effective treatments.

Zinc aids in glioblastoma treatmentKetogenic diet with oxyresveratrol and zinc inhibits glioblastoma and restores memory function and motor coordination.
Moderate relevance, combination focus
We evaluated the potential of zinc in combination with a ketogenic diet and oxyresveratrol in fighting glioblastoma, a highly aggressive brain tumor. Through a series of carefully designed experiments, we examined how these treatments affect tumor growth and overall brain function.
In our study, we induced brain tumors in Wistar rats and then applied our treatment regimen. We tracked various outcomes, including tumor size, proliferation rates, memory function, and motor coordination. By assessing glucose and ketone levels, we gained insights into the metabolic changes occurring as a result of the treatments.
The findings suggested that zinc played a supportive role alongside the ketogenic diet and oxyresveratrol in reducing tumor growth. Moreover, these treatments appeared to enhance memory and motor coordination, indicating a multi-faceted benefit. Overall, this progression offered valuable information about the role of diet and supplementary compounds in battling aggressive brain tumors like glioblastoma.
