We examined the influence of prostaglandins on the initiation of proliferation of growth-arrested human adult aortic and fetal smooth muscle cells. Prostaglandins of the E series (25 nM) exerted a significant (p less than or equal to 0.05) inhibitory effect on DNA synthesis. Inhibition was observed when PGE1 was added in the G1 phase of the cell cycle. PGE1 had no effect when added once DNA synthesis had started. Thus prostaglandins of the E series may inhibit the responsiveness of smooth muscle cells to the mitogenic action of critical growth factors, such as PGDF. This inhibitory response is cell-cycle dependent. Once smooth muscle cells have entered S phase, PGE1 is no longer effective. Our data also suggest that cAMP is involved in the PGE1-induced growth inhibition, since concomitant with PGE1 addition, cAMP levels rose rapidly; addition of the cAMP analogue db-cAMP resulted in a cell-cycle-dependent inhibition pattern comparable to that observed with PGE1.
