ｂｃｌ－２基因是近年发现的第三类肿瘤基因，是一种调控细胞死亡的“存活基因”，可抑制编程性细胞死亡（ｐｒｏｇｒａｍｍｅｄｃｅｌｄｅａｔｈ，ＰＣＤ），又称细胞凋亡（ａｐｏｐｔｏｓｉｓ），故称之为抗凋亡基因。细胞凋亡发生障碍，可导致细胞堆积，而形成肿瘤。本... The bcl-2 gene is a third type of tumor gene discovered in recent years. It is a “survival gene” that regulates cell death and can inhibit programmed cell death (PCD), also known as apoptosis (apoptosis). For anti-apoptotic genes. Apoptosis occurs and can lead to cell accumulation and tumor formation. this...
