Platelet-derived growth factor (PDGF) promotes cell-cycle progression by engaging signaling enzymes such as phospholipase Cgamma (PLCgamma). When activated, PLCgamma cleaves phosphatidylinositol-4,5-bisphosphate to produce inositol-1,4, 5-trisphosphate (IP(3)) and diacylglycerol (DAG). IP(3) stimulates the release of calcium from intracellular stores, which together with DAG activate some protein kinase C (PKC) family members. In this study we focused on putative downstream effectors of PLCgamma - PKC family members. We investigated whether, and when, DAG-responsive PKCs contribute to PDGF-dependent DNA synthesis.
