Figure 5. — EX 527 inhibits the increase of SIRT1 expression induced by liquiritin in ox-LDL-induced hVSMCs. hVSMCs were treated with 80 μM liquiritin or/and 10 μM EX 527 in the presence of 100 μg/mL ox-LDL for 24 h. (a) The mRNA expression of SIRT1 in ox-LDL-induced hVSMCs was detected by RT-qPCR analysis. The fold change calculated against ox-LDL group. (b) The protein expression of SIRT1 in ox-LDL-induced hVSMCs was detected by Western blot analysis. **P < 0.01 vs. ox-LDL; ^## P < 0.05, 0.01 vs. ox-LDL+liquiritin group.
