Summary: This study investigated the characteristics, origin, and roles of uterine luminal fluid-derived extracellular vesicles (EVs) in porcine conceptus implantation. The EVs were found to mainly originate from endometrial epithelial cells, with an increase in concentration starting from day 12 of pregnancy. Functional enrichment analysis revealed that the miRNAs in these EVs potentially regulate EV transportation or conceptus implantation, providing important insights for future translational studies on porcine EVs.

Summary: This study investigated the expression of SAA3 in the pig endometrium during the estrous cycle and pregnancy. It was found that SAA3 had the highest expression on day 12 of pregnancy and was primarily localized to the luminal epithelial cells. In vitro cultures showed that SAA3 expression was induced by IL1B and IFNG. These findings suggest that SAA3 expression in the endometrium is regulated by conceptus-derived IL1B and IFNG, and it could serve as a specific marker for conceptus implantation in pigs.

Summary: Research has shown that caspases are dynamically expressed in the endometrium throughout the estrous cycle and at the maternal-conceptus interface during pregnancy in pigs. The expression of CASP3, CASP6, and CASP7 changes in a stage-specific manner in the endometrium during different reproductive stages. Additionally, the expression of caspases in endometrial cells is influenced by steroid hormones and cytokines, suggesting that caspase action may play an important role in regulating endometrial and placental function in pigs during the implantation period.

Summary: The study revealed that SOX2 plays a crucial role in inner cell mass formation and cell proliferation in early-stage porcine embryogenesis. Disruption of SOX2 inhibits the expression of inner cell mass-related genes and reduces total cell number; while overexpression of SOX2 greatly increases blastocyst cell number but decreases the inner cell mass/trophectoderm ratio.

Summary: The study aimed to improve outcomes for subretinal implantation surgery in pigs through a modified procedure that involved pre-cauterization of the choroid before sclerotomy and the use of an instrument to better fill the scleral opening. The results showed a significant decrease in bleeding, hypotony, and open sclerotomy time, leading to a higher success rate of implantation.

Summary: In this study, the researchers investigated the regulation of prostacyclin (PGI2) synthesis and PGI2 receptor (PTGIR) expression by cytokines, and evaluated the effect of PGI2 on pro-angiogenic gene expression, cell proliferation and migration, cell cycle distribution, and capillary-like structure formation in porcine endometrial cells. They found that IL1ss, IFNgimel, and/or TNFα increased PGI2 secretion and PTGIR expression. PGI2 enhanced pro-angiogenic gene expression, cell proliferation, and cell cycle progression.

Summary: The presence of a more efficient glycolysis mechanism depending on pyruvate in stallion spermatozoa can counteract the detrimental effects of higher glucose concentrations. Incubating spermatozoa with 10 mM pyruvate in a modified Tyrode's media with 67 mM glucose showed increased motility and maintained viability. This improvement is attributed to the conversion of lactate to pyruvate and increased NAD(+) enhancing glycolysis efficiency.

Summary: Ongoing progress in mRNA-Sequencing technologies has contributed to the refinement of assisted reproductive technologies. This study utilized mRNA-Seq datasets of various mammalian species to analyze differential transcript usage (DTU) and identified ten cross-species DTU genes. Gene Ontology (GO) term enrichment analysis revealed the involvement of these genes in RNA and cell-cycle control mechanisms, suggesting their importance during oocyte maturation. Further exploration of these genes' transcript isoforms may lead to the discovery of novel markers for reproductive technologies.

Summary: This study found that Nobiletin (NOB) can promote the cryosurvival and embryo development of porcine sperm after in vitro fertilization (IVF). The addition of NOB improves sperm motility, acrosome integrity, viability, and mitochondrial membrane potential, reduces lipid peroxidation, and increases cleavage and blastocyst formation rates. Furthermore, NOB treatment upregulates the expression of genes related to pluripotency and cell differentiation in the resulting embryos.

Summary: This study investigated the cytotoxicity and toxicological mechanisms of fluorochloridone (FLC) on cultured goat Sertoli cells. The results showed that FLC exposure induced oxidative stress, promoted apoptosis and autophagy, inhibited lysosomal biogenesis, and blocked autophagic flux in goat Sertoli cells. FLC also caused mitochondrial dysfunction and disturbed mitophagy, leading to cell apoptosis. The antioxidant N-acetyl-L-cysteine (NAC) reduced FLC-induced ROS accumulation and reversed the disorder of autophagy levels.

Summary: The study evaluated the effects of E2 treatment on Nelore heifers on day 15 of the estrous cycle, finding that E2 promoted an increase in PGFM concentrations and accelerated functional and structural luteolysis by upregulating the expression of PGR and OXTR. This suggests that within 3 hours after E2 stimulus, the expression of these receptors is associated with triggering luteolysis in cattle.
