转录调节因子 Yin Yang-1 (YY1) 是一种已知在胰腺癌中过度表达的肿瘤抑制因子。我们发现,YY1 的过度表达促进了胰腺癌细胞系中的细胞凋亡,并增加了促凋亡 Bax 蛋白的表达和线粒体定位。荧光素酶报告基因、电泳迁移率变动 (EMSA) 和染色质免疫沉淀 (ChIP) 检测显示 YY1 与 BAX 启动子的结合。此外,YY1通过Bax转录激活和随后的Bax易位至线粒体膜,导致细胞色素c释放和caspase激活,促进胰腺癌细胞凋亡。YY1和BAX在胰腺癌组织中共表达,较高的BAX表达预示患者有更好的预后。 YY1 促进胰腺癌细胞凋亡的能力表明它可能是一个有价值的诊断和治疗靶点。
The transcriptional regulator Yin Yang-1 (YY1) is a tumor suppressor known to be overexpressed in pancreatic cancer. We found that overexpression of YY1 promoted apoptosis and increased the expression and mitochondrial localization of the pro-apoptotic Bax protein in pancreatic cancer cell lines. Luciferase reporter, electrophoretic mobility shift (EMSA), and chromatin immunoprecipitation (ChIP) assays revealed binding of YY1 to the BAX promoter. Moreover, YY1 promoted pancreatic cancer cell apoptosis through Bax transcriptional activation and subsequent translocation of Bax to the mitochondrial membrane, leading to cytochrome c release, and caspase activation.YY1 and BAX are co-expressed in pancreatic cancer tissues and higher BAX expression predicts better outcomes for patients. The ability of YY1 to promote apoptosis in pancreatic cancer cells suggests it may represent a valuable diagnostic and therapeutic target.
