Figure 4. Effect of laminin and forskolin on IRBP gene expression in WERI-Rb1 cells: Northern blot analysis

A: A typical Northern blot analysis showing the effect of forskolin (10 mM)/IBMX (0.5 mM) in 3 day laminin-pretreated WERI-Rb1 cells during a time course (0.5-96 h). B: Relative IRBP/b-actin mRNA that was normalized to its corresponding control. Data are means±S.D. for each treatment group, N=4 per group. Asterisks indicate level of statistical significance: ^* for p<0.05, ^** for p<0.01.
