Figure 3. In mono- and cocultures of pericytes and endothelial cells, PMA treatment increases PKCβII, HuR, and VEGF protein levels. A-B: Mean gray level ratios (mean±SEM) of PKCβII/α-tubulin, HuR/α-tubulin, and VEGF/α-tubulin immunoreactivities were measured with western blotting in pericytes (PC; A) and endothelial cells (EC; B). The comparisons were performed between control (CTR) and PMA-treated (PMA) cells in monoculture (_mono) and in coculture (_cocu) separately. *p<0.05; **p<0.005, n=5.
