Diacylglycerol, but not inositol 1,4,5-trisphosphate, accounts for platelet-derived growth factor-stimulated proliferation of BALB 3T3 cells.


Recently we found that an intracellular event related to phosphatidylinositol 4,5-bisphosphate (PIP2) is crucial for platelet-derived growth factor (PDGF)-induced mitogenesis in fibroblastic cells (Matuoka, K., et al.: Science 239:640-643, 1988). In the present study we examined the mitogenic effects of PIP2 and its hydrolysis products introduced into the… (More)
