  • Title: Regulation of hyaluronan synthases in mouse uterine cervix.
    Author: Uchiyama T, Sakuta T, Kanayama T.
    Journal: Biochem Biophys Res Commun; 2005 Feb 18; 327(3):927-32. PubMed ID: 15649434.
    Abstract:
    We examined the expression pattern of hyaluronan synthase (HAS) mRNAs in the uterine cervix of pregnant mice. The expression levels of HAS-1 and -2 mRNAs peaked at delivery, whereas that of HAS-3 mRNA peaked on the 15th day of pregnancy. The regulation of HAS mRNA expression was examined in pregnant mouse uterine cervical fibroblasts. The expression of HAS-1, -2, and -3 mRNAs was significantly augmented by interleukin-1beta (IL-1beta). Progesterone significantly interfered with expression of HAS-1 and -2 mRNAs, but significantly increased the expression of HAS-3 mRNA. Low-molecular-weight hyaluronan significantly enhanced only the expression of HAS-1 mRNA. These results indicate that HAS in the uterine cervix is regulated in a complex manner by IL-1beta, progesterone, and low-molecular-weight hyaluronan, of which changes in the cervical tissue and serum closely participate in uterine cervical ripening and/or inflammation.
