Prostate:Vinculin通过调节肿瘤细胞的入侵、迁移和增殖来协调前列腺癌的进展

前列腺癌(PCa)是导致男性死亡的主要原因,仍旧需要进一步开发有效治疗PCa的治疗方法。

前列腺癌(PCa)是导致男性死亡的主要原因,仍旧需要进一步开发有效治疗PCa的治疗方法。

最近,有研究人员调查了vinculin(VCL)在PCa体外和体内进展中的潜在作用

研究人员基于TCGA数据库调查了VCL启动子的甲基化水平。通过qRT-PCR、Western blot分析和免疫荧光证实了VCL基因表达的敲除效果。此外,研究人员还使用了鬼笔环肽染色法检测了PCa细胞的形态学变化;还将肿瘤细胞注射到BALB/c裸鼠右侧产生的皮下异种移植模型,调查了VCL在体内肿瘤生长中的作用。结果表明,PCa中VCL启动子的甲基化水平随着年龄和结节转移的进展而显著下调。shRNA能够明显降低VCL的表达。重要的是,VCL的敲除显著改变了细胞形态;抑制了PCa细胞的迁移、侵袭和移动,并抑制了PCa细胞在体外克隆形成和生存能力。此外,VCL的下调能够抑制体内肿瘤的生长。

shVCL能够显著的抑制异种移植模型中肿瘤的生长

最后,研究人员指出,他们的研究全面评估了VCL在体内和体外PCa进展中的作用。研究结果表明了VCL可以成为PCa预后和治疗的潜在靶点
