Figure 4. Effect of HIF-1α shRNA on ANG II-induced increases of vascular endothelial growth factor (VEGF) in glomeruli.
A: Representative photomicrographs showing immunostaining of VEGF in glomeruli (brown color); B: HIF-1α mRNA levels in isolated glomeruli by Real-time RT-PCR analysis. * P < 0.05 vs. other two groups (n = 6).
