Previous studies also indicate that BA-treated cancer cells (glioma, melanoma, neuroblastoma) demonstrated upregulation of the pro-apoptotic Bax protein (Fulda et al. 1997; Wick et al. 1999; Selzer et al. 2000), indicating that plant-derived products rich in BA could be potent agents in the fight against cancer cells. This evidence concerns the gene BAX and central nervous system cancer.
