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.

We explored how magnesium sulfide nanoparticles (MgS NPs) affect the SH-SY5Y neuroblastoma cell line, which is a significant challenge in treating brain cancer. Using a green synthesis method, we created MgS NPs and tested their effects in cultured cells.
When applied at various doses, we observed that 75 µg/mL MgS NPs reduced cancer cell viability by nearly half. The treatment also increased oxidant levels in the cells, aligning with our findings from cytotoxicity tests. Overall, it appears that MgS NPs effectively hinder the growth of neuroblastoma cells.

We explored the impact of the vitamin B6 pathway on glioblastoma, a challenging and aggressive brain cancer. Specifically, we assessed how different cell cultures—2D monolayers and 3D spheroids—responded to treatments that alter vitamin B6 levels. Through comprehensive metabolomics analysis, we found notable differences in the levels of vitamin B6-related metabolites between these two culture methods.
Our key finding was that when we used hydralazine, a small molecule known to lower vitamin B6 levels, it induced cell death specifically in the 3D spheroid cultures of glioblastoma. This suggests a potential new therapeutic strategy targeting the vitamin B6 pathway could benefit glioblastoma treatment.
Thus, this study highlights a novel approach to tackle this aggressive cancer by focusing on the metabolic alterations within the tumor microenvironment, particularly through vitamin B6 modulation.

We explored the impact of vitamin B6, also known as pyridoxine, on the viability and progression of human glioblastoma cells, specifically the U-87 MG cell line. The study involved treating these cells with increasing concentrations of vitamin B6 and monitoring changes over 24 to 72 hours.
Our findings demonstrated that higher doses of pyridoxine resulted in a significant decrease in cell viability, suggesting that it may effectively hinder the growth of glioblastoma. We observed that this reduction in cell viability was likely linked to a slower cell cycle progression and an increase in active caspase 3, a marker of apoptosis or programmed cell death.
Interestingly, while vitamin B6 appeared to enhance the apoptosis process, the levels of Bcl-2, a protein that usually helps cells survive, did not change significantly. Furthermore, when we introduced cobalamin (vitamin B12) alongside pyridoxine, we found that it seemed to counteract some of pyridoxine's harmful effects in terms of cell viability.
Overall, the results imply that vitamin B6 supplementation could potentially be used to promote apoptosis in glioblastoma cells, possibly making it a valuable addition to current cancer therapies.

Magnesium reduces brain injury markersEffect of magnesium on functional outcome and paraclinical parameters of patients undergoing supratentorial craniotomy for brain tumors: a randomized controlled trial.
Moderate significance in findings
We examined how intravenous magnesium sulfate (MgSO4) affects patients undergoing surgery for brain tumors. Sixty patients were divided into two groups: one received magnesium treatment, while the other received a placebo.
The results showed that magnesium lowered significant protein levels linked to brain injury after surgery. However, it didn’t substantially change the overall functional outcomes for the patients. While MgSO4 appears safe and beneficial in reducing specific markers, more research is necessary to fully grasp magnesium's role in brain injury recovery.
