Propofol Regulates HIF-1 α Effect of Expression of Targeted SIRT1 Signal pathway on Kidney Renal Clear Cell Carcinoma

The objective of this study was to investigate the effect of propofol on kidney renal clear cell carcinoma (KIRC) by regulating hypoxia-inducible factor-1α (HIF-1α) expression and silencing signal regulatory factor 1 (SIRT1) signal pathway. In this regard, human KIRC cell line RCC4 was added into 0, 5 and 10 μ G/ml propofol treatment and was divided into a control group (CG), low dose group (LG) and high dose group (HG). CCK8 was used to detect the proliferative ability of the three groups of cells, ELISA was used to detect the level of inflammatory factors in the cells, Western blot was used to detect the protein expression, qPCR was used to detect the related mRNA expression level, and Transwell method was used to detect the invasive ability of the cells in vitro. The experimental results showed that propofol decreased the proliferation and invasion ability of KIRC cells, up-regulated the expression of TGF- β 1, IL-6, TNF- α, HIF-1 α, Fas, bax and FasL, and down-regulated the expression of SIRT1 in a dose-dependent manner. It was concluded that propofol can inhibit the SIRT1 signal pathway by up-regulating the level of HIF-1α in KIRC, which can significantly decrease the proliferation and invasion ability of KIRC cells, induce apoptosis and increase the release of intracellular inflammatory factors.
