A critical role of progesterone (P) during early pregnancy is to induce differentiation of the endometrial stromal cells into specialized decidual cells that support the development of the implanting embryo. The P-induced signaling pathways…
Serotonin (5-hydroxytryptamine; 5-HT), acting via the 5-HT(2A) receptor, up-regulates the transcription and production of interstitial collagenase (matrix metalloproteinase-13; MMP-13), a critical enzyme responsible for maintaining the inte…
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) exerts its toxic action via the aryl hydrocarbon (Ah) receptor, which induces a battery of xenobiotic-metabolizing enzymes, including the cytochrome P450 isozyme, CYP1A1. TCDD-induced 7-ethoxycouma…
The regulation of collagenase gene expression by serotonin and progesterone was investigated in primary cultures of rat uterine smooth muscle cells. Northern blot analysis demonstrates that serotonin (5-hydroxytryptamine (5-HT)), when admin…
The effects of a specific calmodulin inhibitor, N-(6-aminohexyl)-5-chloro-1-naphthalenesulfonamide (W-7) on the synthesis of tissue inhibitor of metalloproteinases (TIMP) and precursor of matrix metalloproteinase 1/tissue collagenase (proMM…
