项目摘要
Liver-specific p38-alpha ablation was found to enhance ROS accumulation, because it reduced the expression ofHSP25. p38-alpha-deficiency also increased the expression of SOX2, c-Jun and Gankyrin and led to enhanced TAA-induced hepatocarcinogenesis. The up-regulation of SOX2 and c-Jun was prevented by administration of the antioxidant butylated hydroxyanisole. The risk of human HCC recurrence is positively correlated with ROS accumulation in the liver. Augmented oxidative stress of liver parenchymal cells may explain the close relationship between liver fibrosis and hepatocarcinogenesis. In addition, expression of CD133, a cancer stem cell marker, was significantly correlated with Gankyrin expression. Gankyrin knockdown decreased the expression of vascular endothelial growth factor (VEGF) and stemness factors such as Nanog and Oct-4 in colorectal and liver cancer cells.
发现肝脏特异性的P38-Alpha消融可增强ROS的积累,因为它降低了HSP25的表达。 p38-Alpha缺陷还增加了Sox2,C-Jun和Gankyrin的表达,并导致TAA诱导的肝癌发生增强。通过施用抗氧化剂丁基羟基烷醇,可以防止Sox2和C-Jun的上调。人类HCC复发的风险与ROS在肝脏中的积累呈正相关。 肝实质细胞的增强氧化应激可能解释了肝纤维化与肝癌发生之间的密切关系。另外,癌症干细胞标记CD133的表达与甘奇林的表达显着相关。 Gankyrin敲低降低了结直肠癌和肝癌细胞中血管内皮生长因子(VEGF)和诸如NANOG和OCT-4之类的干性因子的表达。
