Abstract:Background: infection is a major risk factor in the development of gastric cancer.infection of gastric epithelial cells increases the levels of reactive oxygen species (ROS), activates oncogenes, and leads TOβ-catenin介导的高增殖。 β-胡萝卜素降低ROS水平,抑制氧化剂介导的炎症信号传导的激活,并表现出抗癌特性。进行本研究以确定β-胡萝卜素是否抑制了通过降低β-catenin和磷酸化糖原合酶激酶3β的水平和磷酸化的糖基因和细胞周期蛋白E的表达,以及肿瘤基因的表达。 Gastric epithelial AGS cells were pre-treated withβ-carotene (5 and 10 μM) for 2 hours prior toinfection and cultured for 6 hours (for determination of the levels of p-GSK3β, GSK3β, and β-catenin) and 24 hours (for determination of cell viability and protein levels of c-myc and cyclin E).通过MTT分析确定细胞活力,并通过基于Western印迹的分析确定蛋白质水平。
结果: β-胡萝卜素抑制 - 磷酸盐的磷酸化gsk3β(P-csk3β)的百分比增加, C-Myc和CyclinE。
结论: β-胡萝卜素通过抑制胃皮细胞的高增殖,通过抑制β-catenin信号传导和致癌基因表达。
