Intra-cervical application of Misoprostol at estrus alters the content of cervical hyaluronan and the mRNA expression of follicle stimulating hormone receptor (FSHR), luteinizing hormone receptor (LHR) and cyclooxygenase-2 in the ewe
The complex anatomy the of ovine cervix limits the success of transcervical artificial insemination in sheep, but Misoprostol (a PGE1 analogue) relaxes the cervix and facilitates transcervical artificial insemination. However, the mechanism by which Misoprostol causes cervical relaxation is not know...

| description | The complex anatomy the of ovine cervix limits the success of transcervical artificial insemination in sheep, but Misoprostol (a PGE1 analogue) relaxes the cervix and facilitates transcervical artificial insemination. However, the mechanism by which Misoprostol causes cervical relaxation is not known. This study examined if intra-cervical Misoprostol altered the hyaluronan content and the mRNA expression of COX-2, LHR, or FSHR in the cervix of the estrus ewe. Estrus was synchronized in cyclic ewes with progestagen pessaries and 48h after sponge removal ewes were treated intra-cervically with 0 (controls), 200, or 400μg Misoprostol. Hyaluronan content was determined by ELISA and mRNA expression of LHR, FSHR, and COX-2 was analyzed by in situ hybridization using digoxigenin-11-uridine-5′-triphosphate labeled riboprobes. The hyaluronan content of the cervix was significantly higher in sheep that received 200 (P |
