RT-PCR analysis of PSMB5 (a) and Nrf2 (b), and qPCR analysis (c) of mRNA steady-state levels using total RNA from pterygium and normal conjunctival fibroblasts, respectively, irradiated with different doses of UVB radiation (0–50 mJ/cm2), after pretreatment with PP2. The products for PSMB5 (550 bp), Nrf2 (173 bp) and GAPDH (263 bp) are indicated. L: DNA ladder. (*) indicates significant difference (p < 0.05) compared to control (non irradiated)
