IGF1 and PMA treatment of P1 retinal explants increases expression of rod specific genes. A, B, Quantitative RT-PCR assay showing expression of opsin and Crx in P1 retinal explants cultured for 4 d in the presence of PMA (A) or IGF1 (B). *p < 0.05; **p < 0.005. Beta-actin and GAPDH expression was used to normalize mRNA levels and values are expressed relative to control levels. C, D, Amount of opsin (C) and Crx (D) proteins found in 4 d retinal explants of P1 retinas using Western blot analysis. Beta-actin expression was used to normalize total protein levels. Values in graph are normalized to control levels. *p < 0.05, **p < 0.01. Error bars indicate SEM.
