Liquiritin increases SIRT1 expression in ox-LDL-induced hVSMCs. The mRNA expression levels of SIRT1 in ox-LDL-induced hVSMCs were detected by RT-qPCR analysis. (b) The protein expression levels of SIRT1 in ox-LDL-induced hVSMCs were detected by Western blot analysis. (c) The mRNA expression levels of SIRT1 in plaque and normal tissues of 30 coronary heart disease patients were detected by RT-qPCR analysis. (d) The protein expression levels of SIRT1 in plaque and normal tissues of two random coronary heart disease patients were detected by Western blot analysis. **P < 0.01 vs. Control; #, ## P < 0.05, 0.01 vs. ox-LDL group; $$ P < 0.01 vs. Normal tissue.
