Selective cytotoxicity of solamargine via oxidative stress and caspase-independent mechanisms in human glioblastoma cells. (PubMed, Invest New Drugs)
Here, we investigated the effects of SM on proliferation, clonogenic survival, morphology and migration of IDH-wildtype GB cell lines (U-87MG, U-251MG and T98-G) and non-tumoral astrocytes under normoxic and hypoxic conditions, as well as its interaction with temozolomide (TMZ)...However, cleaved caspase-3 and p53 were not detected, suggesting a predominantly non-apoptotic mode of cell death. Together, these findings support SM as a promising candidate for IDH-wildtype GB therapy and underscore the need for further studies to clarify its mechanisms of action and optimize its therapeutic use.
