摘要: 目的 探讨丙泊酚经HIF-1α信号通路对头颈鳞状细胞癌SCC-74细胞增殖、凋亡与侵袭的影响。方法 体外培养SCC-74细胞,丙泊酚低剂量组、丙泊酚中剂量组和丙泊酚高剂量组分别给予终浓度为2.5、10、20 μg/mL的丙泊酚,对照组给予等量DMEM培养液,继续培养48 h后收获细胞,检测SCC-74细胞增殖、凋亡与侵袭情况,同时检测SCC-74细胞中Akt、p-Akt、HIF-1α、Fas、FasL、Bcl-2、Bax蛋白和mRNA水平。结果 与对照组比较,各丙泊酚剂量组SCC-74细胞增殖率和侵袭数降低,细胞凋亡率增加(P<0.05);与对照组比较,各丙泊酚剂量组SCC-74细胞中p-Akt蛋白、Bcl-2蛋白和mRNA水平降低,HIF-1α、Fas、FasL和Bax蛋白和mRNA水平增高,呈剂量依赖性(P<0.05)。各组SCC-74细胞中Akt蛋白和mRNA水平无统计学差异(P>0.05)。结论 丙泊酚通过激活HIF-1α信号通路,抑制SCC-74细胞增殖和侵袭,促进SCC-74细胞凋亡。

Abstract: Objective The aim of this study was to investigate,To investigate the effects of propofol on the proliferation,apoptosis and invasion of SCC-74 cells via HIF-1 α signal pathway.Methods SCC-74 cells were cultured in vitro.The final concentrations of propofol were 2.5,10 and 20 μg/mL in low-dose propofol groups,medium-dose propofol group and high-dose propofol groups,respectively.The control group was given the same amount of DMEM culture medium,and the cells were harvested after treatment for 48h.The proliferation,apoptosis and invasion of SCC-74 cells were detected.At the same time,the levels of Akt,p-Akt,HIF-1 α,Fas,FasL,Bcl-2 and Bax protein and mRNA were detected.Results Compared with the control group,the proliferation rate and invasion number of SCC-74 cells in all propofol dose groups was significantly decreased,the apoptosis rate of SCC-74 cells increased(P<0.05),and the levels of p-Akt and bcl-2 protein in SCC-74 cells was significantly decreased,the levels of HIF-1 α,Bcl-2,Fas,FasL and Bax protein increased in a dose-dependent manner(P<0.05).There was no significant change in the expression of Akt in SCC-74 cells(P>0.05).Conclusion Propofol can inhibit the proliferation and invasion of SCC-74 cells and promote the apoptosis of SCC-74 cells by activating HIF-1 α signal pathway.
