Downregulation of LHCGR Attenuates COX-2 Expression and Induces Luteinized Unruptured Follicle Syndrome in Endometriosis

Frontiers in Endocrinology, 2022
An association between endometriosis and luteinized unruptured follicle syndrome (LUFs) has long been identified. Although inactivating mutation of luteinizing hormone/choriogonadotropin receptor (LHGCR) results in LUFs, whether LHCGR contributes to ...

Comparative transcriptome analysis reveals involvement of FOXL2 in regulation of ovulation cycle in chicken

Poultry Science
The egg-laying performance is closely related to ovulation of chicken. Ovulation is very complex and highly coordinated physiological process. However, little is known about the ovulation-related synergistic actions of molecules and their signaling. Here,

Expression of Relaxin Family Peptide Receptors 1 and 3 in the Ovarian Follicle of Japanese Quail

The Journal of Poultry Science
In our previous studies, we demonstrated that the primary source of relaxin 3 (RLN3) in Japanese quail is ovarian granulosa cells. Although several relaxin family peptide (RXFP) receptors have been sequenced, the intricacies of these receptors in avian ...

Rodent Models of Non-classical Progesterone Action Regulating Ovulation

Frontiers in Endocrinology, 2017
It is becoming clear that steroid hormones act not only by binding to nuclear receptors that associate with specific response elements in the nucleus but also by binding to receptors on the cell membrane. In this newly discovered manner, steroid hormones
