WebSep 14, 2024 · However, the overexpression of p21, p53 and Bax were observed along with the activation of caspases-3 and -9 and PARP cleavage to achieve apoptosis in prostate cancer cells. EGCG primarily activates and promotes the cell cycle arrest and apoptosis through p53-mediated signal transduction along with the effect of p21 and Bax . The expression of BAX is upregulated by the tumor suppressor protein p53, and BAX has been shown to be involved in p53-mediated apoptosis. The p53 protein is a transcription factor that, when activated as part of the cell's response to stress, regulates many downstream target genes, including BAX.
