Abstract:
:The effect of prostaglandins (PG) on initiation of DNA synthesis in arterial smooth muscle cells (SMC) stimulated with platelet-derived growth factor (PDGF) was examined. A concentration of 10 ng/ml PGE1 inhibited DNA synthesis, measured as autoradiographically labeled nuclei, by about 70%. Similar results were obtained with PGE2 and PGD2 but at concentrations 10-20 times higher, whereas PGF2 alpha lacked effect. The inhibitory action of the prostaglandins was restricted to the first 6 h of the lag phase. Treatment with PGE1 also raised the intracellular concentration of cyclic AMP, indicating that the inhibition may be mediated via changes in the levels of cyclic nucleotides.
