  • Title: Effects of prostaglandins on the production of collagenase by rabbit uterine cervical fibroblasts.
    Author: Goshowaki H, Ito A, Mori Y.
    Journal: Prostaglandins; 1988 Jul; 36(1):107-14. PubMed ID: 2845482.
    Abstract:
    Effects of prostaglandins on the production of collagenase by rabbit uterine cervical fibroblasts were investigated. Exogenous prostaglandin E2 (PGE2) and PGF2 alpha significantly stimulated the production of collagenase in a dose dependent manner, whereas PGI2 did not. Addition of arachidonic acid in the presence of absence of indomethacin to the cell culture did not show any increase in collagenase production. Recombinant human interleukin-1 (rhIL-1) also promoted the production of cervical collagenase independently of endogenous prostaglandin(s). Furthermore both exogenous PGE2 and PGF2 alpha enhanced the rhIL-1-induced collagenase production whereas PGI2 and/or indomethacin did not. These results suggested that exogenous PGE2 and PGF2 alpha but not endogenous prostaglandin(s) participate in cervical ripening and dilation by enhancing collagenase production by rabbit uterine cervical cells.
