Fig. 6From: UVB-mediated down-regulation of proteasome in cultured human primary pterygium fibroblastsRT-PCR analysis of Nrf2 mRNA steady-state levels using total RNA from pterygium fibroblasts, irradiated with different doses of UVB radiation (0–50 mJ/cm2). The products for Nrf2 (173 bp) and GAPDH (263 bp) are indicated. L: DNA ladder. (*) indicates significant difference (p < 0.05) compared to control (non irradiated)Back to article page
