The effects of dehydroepiandrosterone 3-sulfate (DHAS) and 17 beta-estradiol (E2) on collagen and noncollagen protein syntheses by rabbit uterine cervical cells were studied, and their effects on latent collagenase synthesis were compared. DHAS (1 X 10(-6) M) stimulated the synthesis of latent collagenase and did not affect the cell number and [3H]thymidine incorporation into DNA, whereas E2 had no effect on collagenase synthesis. On the other hand, neither DHAS (1 X 10(-6) M) nor E2 (1 X 10(-10)-1 X 10(-6) M) showed effects on collagen and noncollagen protein syntheses. These results suggest that the stimulative effect of DHAS on cervical ripening is mediated mainly by the stimulation of collagen catabolism, and that E2 does not concern the changes in the concentration of collagen and noncollagen protein in uterine cervix of the rabbit during pregnancy at term.
