The male reproductive impairment caused by environmental estrogens (EEs) stands as a pivotal research area in environmental toxicology. Alpha2-macroglobulin (A2M) emerges as a promising molecule capable of counteracting oxidative stress induced by EEs. This study conducted exposure experiments spanning PND1 to PND56 employing ICR mice, aiming to delve into the expression patterns of A2M and its modulated IL-6 in the testicular tissue of mice subsequent to diethylstilbestrol (DES) and benzophenone (BP) exposure, while elucidating the pivotal role of ERs in this intricate process.

The quality of the recipient cytoplasm was reported as a crucial factor in maintaining the vitality of SCNT embryos and SCNT efficiency for dairy cows. Compared with oocytes matured in vivo, oocytes matured in vitro showed abnormal accumulation and metabolism of cytoplasmic lipids. L-carnitine treatment was found to control fatty acid transport into the mitochondrial β-oxidation pathway, which improved the process of lipid metabolism.

Long non-coding RNAs (lncRNAs) act as competing endogenous RNAs (ceRNAs) that play a significant role in bovine embryo development; but the influence of sperm-borne lncRNA on the preimplantation development of bovine embryos has not been reported in detail. In this study, we aimed to clarify how sperm-borne lncRNAs can act to regulate early development of bovine embryos. Utilizing high-throughput sequencing technology and quantitative real-time PCR (qPCR), we found that the lncRNA, loc100847420, was highly enriched in bovine sperm and was carried into the oocyte during fertilization.

Background: Premature ovarian insufficiency (POI) is a common clinical problem, however, there are currently no effective therapies. Pyroptosis induced by the NLRP3 inflammasome is considered a possible mechanism of POI. Placental mesenchymal stem cells (PMSCs) have excellent immunomodulatory potential and offer a promising method for treating POI.

Stress induced by changes in the internal or external environment in humans and animals leads to intestinal epithelial damage, in a manner that is associated with impaired intestinal barrier function. However, the role of the stress hormone norepinephrine (NE) in impairments in barrier function remains poorly understood. In the present study, a rat heat-exposed model was used to observe changes in the tight junction proteins Occludin and zonula occludens-1 (ZO-1), in addition to those in protease-activated receptor 2 (PAR-2) and transient receptor potential ankyrin 1 channel (TRPA1) in colon.

Di-(2-ethylhexyl) phthalate (DEHP) is one of the most commonly used plasticizers, and it is widely applied in various plastic products. DEHP is an endocrine-disrupting chemical (EDC) that has been shown to disrupt the function of reproductive system in females. Although many studies have shown that DEHP potentially causes female reproductive toxicity, including depletion of the primordial follicle and decreased sex hormone production, the specific mechanisms by which DEHP affects female reproduction remain unknown.

Liuweidihuang Pill (LP) is a traditional Chinese herbal formula that is often used in clinical practice to treat kidney deficiency syndrome. The present study investigated the antiaging effects of LP in a D-galactose- (D-Gal-) induced subacute aging rat model. The study also attempted to explore whether anti-inflammatory mechanisms that underpin the antiaging effects are mediated by the AMPK/SIRT1/NF-B signaling pathway.

Background: Human umbilical cord-derived MSCs (hUC-MSCs) have been identified as promising seeding cells in tissue engineering and clinical applications of regenerative medicine due to their advantages of simple acquisition procedure and the capability to come from a young tissue donor over the other MSCs sources. In clinical applications, large scale production is required and optimal cryopreservation and culture conditions are essential to autologous and allogeneic transplantation in the future. However, the influence of cryopreserved post-thaw and long-term culture on hUC-MSCs remains unknown, especially in terms of specific protein expression.

Cryopreservation and transplantation of the ovarian tissue is an alternative method by which malignant tumor survivors can recover fertility. Previously, it was reported that follicle stimulating hormone (FSH) promoted the survival and functioning of the ovarian tissue after in vitro cultivation. In this study, the expression of the luteinizing hormone receptor (LHR) was observed on the granule cell membrane after luteinizing hormone (LH) (0.

With the development of regenerative medicine, a variety of mesenchymal stem cells (MSCs) are increasingly considered for the treatment of premature ovarian failure (POF). Reportedly, bone marrow-derived MSCs (BMSCs) improve the ovarian reserve, which mainly depends on homing and paracrine activities. Furthermore, paracrine factors secreted by these stem cells play an important role in ovarian recovery.

Article Synopsis
  • The study aimed to explore how a single heat stress treatment affects spermatogenic cells in male mice by comparing a control group with a heat stress group.
  • After exposing mice to high temperatures, significant changes were observed in the testicular organ index and morphology, particularly in the arrangement and quantity of spermatogenic cells over 1, 7, and 14 days.
  • The results indicated that while heat stress initially leads to reduced spermatogenic cell numbers and impaired PLZF expression, the spermatogenic cells begin to recover after 14 days, suggesting potential for recovery from heat-induced damage.

Background: Mesenchymal stem cells (MSCs) in tumors have emerged as progenitors involved in stroma formation and metastasis of cancers, partially owing to their abilities to differentially express paracrine factors related to the proliferation and invasion of cancer cells. In this regard, increasing evidence has shown that MSCs have impacts on the malignancy of colon cancer, however, the underpinning mechanisms by which MSCs promote cancer metastasis remain elusive.

Methods: To investigate the crosstalk between adipose-derived MSCs (AMSCs) isolated from adipose tissues and colon cancer cells, a co-culture transwell model of AMSCs and colon cancer cells was employed, and the activation of Wnt signaling and paracrine factors in colon cancer cells and AMSCs were measured.

Endoplasmic reticulum stress (ERS), which is a novel pathway of regulating cellular apoptosis and the function of ERS during corpus luteum (CL) regression, is explored. Early-luteal stage (day 2), mid-luteal stage (day 7), and late-luteal stage (day 14 and 20) were induced, and the apoptosis of luteal cells was detected by a terminal 2'-deoxyuridine 5'-triphosphate nick-end labeling (TUNEL) assay. The apoptotic cells were increased with the regression of CL, especially during the late-luteal stage.

The aim of the present study was to investigate the effects of recombinant human anti-mullerian hormone (rhAMH) on Stem Cell Factor (SCF) expression in human granulosa cells (GCs). GCs were obtained from infertile patients undergoing IVF-ET cycles and cultured with 20 ng/ml of rhAMH. The levels of SCF mRNA and protein were detected in both matched and experimental group by real-time PCR, immunofluorescence, and ELISA, respectively, on day 4 of culture.
