Glycyrrhizic acid inhibits apoptosis and fibrosis in carbon-tetrachloride-induced rat liver injury

Figure 3 Effects of glycyrrhizic acid on α-SMA expression were estimated by western blotting and real-time polymerase chain reaction. A: Total proteins were extracted from the livers of rats in the different treatment groups. GAPDH was used to confirm the same sample loading in each lane; B: Total RNA was extracted from the livers of rats in the different treatment groups. GAPDH mRNA was included to normalize the expression of mRNA. Data are shown as mean ± SD. ^aP < 0.05 vs the CCl₄ group.
