DESCRIPTION: (Adapted from applicant's abstract) The studies proposed in this application will: (1) determine if progesterone withdrawal at different stages of decidualization would affect the expression of bcl-2 gene family members; this information will be correlated with DNA fragmentation in the decidual cells; (2) investigate why induced Bax expression failed to cause death of decidual cells by determining if Bax activity is compromised by Bcl-xL or hsp-25; (3) determine the expression of TGF-beta and apoptotic mediators (cathepsin-D, cytochrome- c, apaf-1, and caspase-3) in the GG-AD decidual cell line, and assess the consequence of overexpressing bax or inhibiting bax and cathepsin-D in GG-AD cells.

描述：（改编自申请人摘要）拟定研究 在本申请中将：（1）确定是否在 蜕膜化的不同阶段影响bcl-2的表达 基因家族成员;这些信息将与DNA （2）探讨Bax诱导的原因 通过确定Bax是否能引起蜕膜细胞死亡， 活性被Bcl-xL或hsp-25损害;（3）确定 TGF-β和凋亡介质（组织蛋白酶-D，细胞色素-D）的表达， c、apaf-1和caspase-3）在GG-AD蜕膜细胞系中的表达，并评估 过度表达bax或抑制bax和组织蛋白酶-D结果 在GG-AD细胞中。
