Androgen synthesis cell-specific CREBZF deficiency alters adrenal cortex steroid secretion and develops behavioral abnormalities in adult male mice.

The global challenge of male infertility is escalating, notably due to the decreased testosterone (T) synthesis in testicular Leydig cells under stress, underscoring the critical need for a more profound understanding of its regulatory mechanisms. CREBZF, a novel basic region-leucine zipper transcription factor, regulates testosterone synthesis in mouse Leydig cells in vitro; however, further validation through in vivo experiments is essential. Our study utilized Cyp17a1-Cre to knock out CREBZF in androgen-synthesis cells and explored the physiological roles of CREBZF in fertility, steroid hormone synthesis, and behaviors in adult male mice.

LncRNA STAT3-AS regulates endometrial receptivity via the STAT3 signaling pathway.

Endometrial receptivity is critical for the successful establishment of pregnancy in ruminants. Interferon tau (IFNT) plays a key role in promoting embryo attachment by activating the Janus kinase/signal transducer and activator of transcription pathway, which induces the expression of a series of interferon-stimulated genes (ISGs). In our previous study, sequencing analysis of goat endometrial epithelial cells (gEECs) treated with 20 ng/mL IFNT revealed a differentially expressed long non-coding RNA located on the STAT3 antisense chain, which we designated STAT3-AS.

Resveratrol and lycium barbarum polysaccharide improve Qinling giant panda (Ailuropoda melanoleuca Qinlingensis) sperm quality during cryopreservation.

Background: Semen cryopreservation has become an essential tool for conservation efforts of the giant panda (Ailuropoda melanoleuca); however, it is severely detrimental to sperm quality. Evidence has shown that antioxidants have the potential to reverse cryopreservation-induced damage in sperm. The purpose of this study was to screen effective antioxidants that could retain sperm quality during cryopreservation and to determine the optimal dose.

Transcriptomic Analysis of STAT1/3 in the Goat Endometrium During Embryo Implantation.

Interferon tau (IFNT), a pregnancy recognition signal in ruminants, promotes the establishment of embryo implantation by inducing the expression of interferon-stimulated genes (ISGs) via the Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway. However, the precise regulatory mechanism of IFNT in goat embryo implantation remains largely unknown. In this study, we performed RNA sequencing of goat endometrial epithelial cells (gEECs) with or without 20 ng/mL IFNT treatment.

Ufmylation regulates granulosa cell apoptosis via ER stress but not oxidative stress during goat follicular atresia.

Follicular atresia is primarily caused by granulosa cell (GC) apoptosis, although the mechanisms are largely unknown. Ufmylation is a recently identified ubiquitin-like post-translational modifier that plays an important role in cell proliferation and apoptosis. The purpose of this study was to investigate the effects of Ufmylation on GC apoptosis during goat follicular atresia.

UFMylation is associated with LPS-induced inflammatory response in goat endometrial epithelial cells.

The endometrium plays an important role in the defence against invading pathogens, although the mechanisms are not clear. UFMylation is a recently discovered novel ubiquitination-like modification system that plays a pivotal role in inflammation and the immune response. The purpose of this study was to investigate the effects of UFMylation on lipopolysaccharide (LPS)-induced inflammatory responses in immortalized goat endometrial epithelial cells (gEECs).
