From: UVB-mediated down-regulation of proteasome in cultured human primary pterygium fibroblasts
RT-PCR (a) and qPCR (b) analysis of PSMB5 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). The products for PSMB5 (550 bp) and GAPDH (263 bp) are indicated. L: DNA ladder. Data represent the mean ± SD of three independent experiments. (*) indicates significant difference (p < 0.05) compared to control (non irradiated)
