BCL2L1 and prostate cancer: These mechanisms have also been described in several studies, such as in DU145 prostate cancer lines and SNU-16 and GES-1 gastric cancer lines, probably due to a decrease in the expression of anti-apoptotic proteins (Bcl-2 and Bcl-xl), which initiate caspase signaling that is responsible for the destruction of cell structure and consequent apoptotic death.
