ACTA1 and Hepatic fibrosis: The expression of α‐SMA in mouse liver tissue was ~16‐fold higher than that of the control group (p < 0.05), whereas the expression of α‐SMA in the uridine treatment group was ~fivefold than that of the control group (p < 0.05), indicating uridine can reduce α‐SMA expression in liver tissues of mice with liver fibrosis induced by CCl4 (p < 0.05, uridine + CCl4 group vs. CCl4 group).
