Members of the lymphoma apoptosis regulatory family are considered to be regulators of cell death, including Bcl-2, Bcl-xl, and MCL-1, acting as chemical inhibitors of the pro-apoptotic protein Bax, which inhibits the release of Bax and cytochrome c and exerts an anti-apoptotic effect [70,71,72]. The gene discussed is BCL2L1; the disease is lymphoma.
