Objective: To investigate the effects of PKGⅡ on tumor suppressor genes including PTEN,p21,p53,breast cancer type 1 susceptibility protein( BRCA1) and BRCA2 in breast cancer cell line MCF-7. Methods: MCF-7 cells were transfected with adenoviral vector encoding cDNA of PKGⅡ and the kinases were activated by respective activator. Western blotting was applied to detect the influence of PKGⅡ on the expression of tumor suppressor proteins,including p53,p21,PTEN,BRCA1 and BRCA2. Results:When PKG Ⅱ expression and ...
乳腺癌是女性常见肿瘤,近年来发病率仍在逐渐上升,且发病人群呈年轻化趋势,严重危害了女性患者的健康[1]。乳腺癌的分子发病机制和生物治疗一直以来都是国内外学者研究的重点。Ⅱ型c GMP依赖性蛋白激酶(typeⅡc GMP-de-pendent protein kinases,PKGⅡ)是一种丝氨酸/苏氨酸蛋白?
