EA inhibited the expression of collagen I and III in HSFs in a dose-dependent manner. A The relative mRNA levels of COL1A1, COL1A2, and COL3A1 in different experimental groups, as detected using qPCR (n = 5). B The protein levels of collagen I, collagen III, and GAPDH in different experimental groups, as detected using western blotting, data were collected from three independent experiments. Data are presented as the mean ± SD; #P > 0.05, *P < 0.05 and **P < 0.01
