A-740003 decreased the expression of proliferating cell nuclear antigen (PCNA). Immunofluorescence co-staining of PCNA (Red) with α-SMA (Green) in the a sham, b P/MCT vehicle group, c P/MCT + CA group, d P/MCT + DA group and e negative control. f The mean percentage of PCNA-positive α-SMA cells (magnification × 40, bar = 50 μm). Data are the mean ± SD, n = 6. **p < 0.01 compared with the sham group; †p < 0.05 compared with the P/MCT vehicle group
