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...

Cortactin knockdown results in disruption of basal TBCs and alters turnover of Sertoli cell ESs in R. norvegicus
Biol Reprod. 2021 Aug 23:ioab161. doi: 10.1093/biolre/ioab161. Online ahead of print.ABSTRACTHere we explore the prediction that long-term knockdown of cortactin (CTTN), a component of tubulobulbar complexes (TBCs), disrupts TBCs in Sertoli cells and alters the turnover of basal ectoplasmic specializations (ESs). In rats, intratesticular injections of siRNA targeting CTTN (siCTTN) in one testis and non-targeting siRNA (siControl) in the contralateral testis were done on days 0, 2, 4, 6, and 8. The experiment was terminated on day 9 and testes were analyzed by either Western Blotting, or by stimulated emission depletion (ST...

The IL6/sIL-6R α trans-signaling increases PGE2 production in human granulosa cells
In conclusion, IL6 trans-signaling upregulates the expression of PTGS2 and increases the production of PGE2 via the JAK2/STAT3/SOCS3 signaling pathway in hGL cells. Our findings provide insights into the molecular mechanisms by which IL6 trans-signaling may potentially modulate the event of ovulation in human ovaries.PMID:34198336 | DOI:10.1093/biolre/ioab128
