Summary: The study investigates the regulation of oocyte growth and maturation in the ricefield eel, which has become an important aquaculture species in China. The researchers classified the development of ricefield eel ovarian follicles into nine stages and performed transcriptomic analysis on isolated ovarian follicles from different stages. The study identifies several genes and pathways that may be involved in oocyte growth and maturation in ricefield eels.

Summary: The GH-IGFs axis is essential in regulating physiological functions in teleost fish. Nutritional status and fasting/refeeding have significant effects on the expression of IGF genes. IGFs play crucial roles in growth, reproduction, and other physiological functions in teleost fish.

Summary: The study showed that chlorpyrifos had toxic effects on porcine oocytes, including delaying meiotic progression, decreasing polar body extrusion, disrupting spindle assembly and causing DNA damage, as well as impairing cytoplasmic maturation. Pterostilbene was able to effectively alleviate the damage caused by chlorpyrifos and improve oocyte maturation and embryonic development.

Summary: This study found that the inhibition of the interaction between the Hippo effector YAP or its transcriptional co-activator TAZ with the TEAD family of transcription factors is critical for the cumulus expansion-related events induced by the EGF network in cumulus-oocyte complexes (COCs). These findings provide important insights into the functional relevance of cumulus expansion and oocyte maturation in monovulatory species, and may serve as potential targets to improve the efficiency of in vitro maturation (IVM) systems.

Summary: Breeding programs for barramundi are hindered by lack of control over sexual development. Hormonally-induced precocious female barramundi have shown reproductive ability and can produce sufficient offspring. Further research can enhance the spawning capacity of precocious females.

Summary: The quality of oocytes from obese women can be compromised due to imbalanced lipid metabolism, which is crucial for oocyte development and maturation. Lipids play a significant role in various biological processes of oocyte development and are important for determining oocyte quality and cryopreservation for fertilization.

Summary: Meiosis is essential for sexual reproduction, with oocytes in female mammals beginning meiosis before birth and sustaining it through dictyate stage before ovulation. Fine-tuning of meiotic progression is crucial for fertility, as any disruption can lead to oogenesis failure and impact overall reproductive health. Understanding the regulatory network of oocyte meiosis is key to comprehending mammalian reproduction and the consequences of misregulation on infertility.

Summary: By performing single-cell analysis, this study identified the differentially expressed genes (DEGs) and pathways related to mitochondria during human oocyte maturation. The results showed that oxidative phosphorylation, pyruvate metabolism, peroxisome, and amino acid metabolism pathways played important roles in oocyte maturation. Additionally, it was observed that mitochondria were regulated by nuclear genes to meet the developmental needs, and the current in vitro maturation culture medium should be optimized based on these findings.

Summary: This study found that cypermethrin (CYP) has a toxic effect on porcine oocyte maturation, while astaxanthin (AST) can protect oocyte maturation. CYP causes DNA damage and endoplasmic reticulum dysfunction in oocytes, while AST can alleviate these defects. This study provides a potential strategy to prevent pesticide toxicity and protect oocyte maturation in mammalian reproduction.

Summary: Exposure to high temperature has been found to negatively affect the development of porcine oocytes. It induces mitochondrial dysfunction, ER stress, abnormal Golgi apparatus distribution, and lysosomal damage, leading to the failure of meiotic maturation in the oocytes.

Summary: This study examines several biomarkers in the cumulus-oocyte complex for their predictive significance in evaluating oocyte developmental competence and IVF outcomes. While these biomarkers show potential for predicting oocyte competency, challenges limit their practical application in IVF as prognostic tools.
