Impact of growth hormone-releasing hormone (GHRH) antagonist on Decidual stromal cell growth and apoptosis in vitro
Biol Reprod. 2021 Nov 18:ioab214. doi: 10.1093/biolre/ioab214. Online ahead of print.ABSTRACTEndometrial stromal cells remodeling is critical during human pregnancy. GHRH and its functional receptor have been shown to be expressed in gynecological cancer cells and eutopic endometrial stromal cells. Recent studies have demonstrated the potential clinical uses of antagonists of GHRH as effective antitumor agents because of its directly antagonistic effect on the locally produced GHRH in gynecological tumors. However, the impact of GHRH antagonists on normal endometrial stromal cell growth remained to be elucidated. The aim o...

HMGA2 is regulated by LIN28 and BRCA1 in human placental cells †.
HMGA2 is regulated by LIN28 and BRCA1 in human placental cells†. Biol Reprod. 2018 Aug 18;: Authors: West RC, McWhorter ES, Ali A, Goetzman LN, Russ JE, Anthony RV, Bouma GJ, Winger QA Abstract The chromatin associated transcription factor HMGA2 is a downstream target of let-7 miRNAs and binds to chromatin to regulate gene expression. Inhibition of let-7 miRNAs by RNA binding proteins LIN28A and LIN28B is necessary during early embryogenesis to ensure stable expression of HMGA2. In addition to LIN28, HMGA2 is regulated by a BRCA1/ZNF350/CtIP repressor complex. In normal tissues, the BRCA1/ZNF350/CtI...

Deletion of Arid1a in Reproductive Tract Mesenchymal Cells Reduces Fertility in Female Mice.
Abstract Women with endometriosis can suffer from decreased fecundity or complete infertility via abnormal oocyte function or impaired placental-uterine interactions required for normal pregnancy establishment and maintenance. Although AT-rich interactive domain 1A (SWI-like) (ARID1A) is a putative tumor suppressor in human endometrial cancers and endometriosis-associated ovarian cancers, little is known about its role in normal uterine function. To study the potential function of ARID1A in the female reproductive tract, we generated mice with a conditional knockout of Arid1a using anti-Müllerian hormone receptor...

RhoGDI2 Is Expressed in Human Trophoblasts and Involved in Their Migration by Inhibiting the Activation of RAC1.
In conclusion, RhoGDI2 inhibits trophoblast cell migration, and this function may involve suppression of RAC1 activation. PMID: 24554735 [PubMed - as supplied by publisher]
