The anti-apoptotic subfamily includes Bcl-2, Bcl-extra large (XL), Bcl-W, myeloid cell leukemia1 (Mcl-1), and Burkholderia lethal factor 1 (BLF1)/A-1 [15, 37–40], but whether these other proteins are involved in GKB-induced lung cancer cell autophagy remains to be studied. This evidence concerns the gene BCL2 and lung cancer.
