BCL2L1 (BCL2 Like 1): BCL2L1, also known as Bcl-xL, is a member of the Bcl-2 protein family that plays a pivotal role in the regulation of apoptosis, or programmed cell death. By inhibiting the release of pro-apoptotic factors from mitochondria, BCL2L1 promotes cell survival and is crucial for maintaining cellular integrity under stress conditions. It is expressed in a variety of tissues and is involved in the development and progression of diseases, including cancer, by helping cancer cells evade apoptosis. The overexpression of BCL2L1 has been associated with resistance to chemotherapy and poor prognosis in various types of cancer....
