During cellular stress, the master regulators of intrinsic self-death (apoptosis) are BCL-2 family proteins. The BCL-2 family proteins play a key role in apoptosis and are tightly regulated via other BCL-2 family proteins, non-BCL-2 protein suppressors, and epigenetic modifications. As the name implies, these proteins possess one or two of the four BCL-2 homology domains (BH1–BH4). According to their roles, they are classified as pro-apoptotic or pro-survival proteins. BH-3-only proteins possess a single BH3 domain and are specific/key effector proteins for intracellular death commitment, particularly in the context of cell survival and programmed cell death. This delicate interplay among the BCL-2 family members is essential for maintaining the primary hemostasis, or balance, of cell fate. The anti-apoptotic proteins, such as BCL-2 and BCL-XL, promote cell survival by inhibiting apoptosis. On the other hand, the pro-apoptotic proteins, such as BAX and BAK, drive apoptosis. It ensures that cells are able to respond appropriately to various internal and external signals, ultimately determining whether a cell survives or undergoes programmed cell death. Understanding and targeting this delicate balance is a promising avenue for developing therapeutic strategies to modulate cell fate and treat various diseases. The molecular pathogenesis of BCL-2 family proteins in blood disorders involves differential expression of these components resulting in the dysregulation of the pathway contributing to cell survival and resistance to apoptosis as observed in follicular lymphoma, diffuse large B-cell lymphoma, acute lymphoblastic leukemia, and acute myeloid leukemia. Such dysregulation is a major impediment to standard therapies and aids in chemo resistance. Studies show some promising clinical outcomes with antineoplastic agent venetoclax either as a monotherapy or in combination with other agents. This review discusses recent studies on the regulation of BCL-2 family proteins which might provide a molecular landscape for their clinical implications in blood disorders.
引言Bcl-2蛋白质家族包括功能相反的,尽管结构相关的蛋白质[1]。创始成员Bcl-2在1980年代中期发现了其与血液癌(如卵泡淋巴瘤)的染色体易位(t(14; 18))特征[2-5]。然而,直到1988年,它的真实功能才被发现是一种促进细胞存活而不是细胞增殖的癌基因,就像当时其他已知的致癌基因一样[6]。后来发现了其他几种促生存蛋白(BCl-XL,MCL-1,BCL-W和BFL-1),所有这些都与称为Bcl-2同源性(BH1 - 4)结构域的四个序列同源性区域相关[7-10]。在具有促进死亡功能的蛋白质子集中也发现了这些,即Bax,Bak和Bok(以下简称Bax/Bak蛋白)[11-13]。并行,第二组促凋亡蛋白(即BAD,BIM,BID,BIK,BMF,NOXA,PUMA,HRK)也被发现仅具有BH3域,因此称为仅BH3蛋白[14-21]。生化和遗传学研究很快揭示了一般的途径,现在称为内在的求主途径,通过该途径,细胞会自杀以响应多种应力(例如生长因子含量,活性氧,内质网应激,减轻DNA的化学疗法)。在健康的细胞中,Bax/Bak蛋白在细胞质或与线粒体上的促蛋白结合的“灭活”状态下存在[12,22 - 26]。死亡刺激后,凋亡是通过仅BH3蛋白的转录或翻译后上调引发的。这些与生存蛋白结合,并释放任何结合的“活化的” Bax/Bak样蛋白,或者,它们可以直接结合Bax/Bak,以诱导构象变化,使它们能够寡聚并在线粒体外膜中形成孔隙,从而释放出Cyto-Chrome [27 - 31],从而释放出Cyto-Chrome [2]。细胞色素c促进了APAF-1的寡聚和凋亡小体的组装,该分子平台是一种分子平台,可以使蛋白水解caspase酶(caspase 9,caspase 9,然后是caspase 3/7)进行顺序激活[33] [33] [33],它裂解了重要的细胞内底物,导致了细胞的衰老。通常,细胞凋亡受到促源性蛋白的限制,从而隔离了其促凋亡的反应。当促凋亡蛋白的水平压倒了生存分子时,凋亡随之而来。由于各种细胞缺陷而导致的失控凋亡,包括发表的记录的异常表达:2021年9月13日
