Figure 2. Western blot analysis of ALDH3A1, PDIA3, and PRDX2. A: Representative images of western blot analysis, examining the expression of ALDH3A1, PDIA3, and PRDX2 in pterygium and healthy conjunctiva tissue. GAPDH protein was used as an internal control. B: Statistically significant differences were observed between the pterygium and the healthy conjunctiva (p<0.05, n=6 in each group).
