AI Article Synopsis
- The study aimed to investigate the relationship between Notch pathway molecule expression in cumulus cells and the quality of zygotes and embryos in PCOS patients.
- A total of 200 cumulus complexes were collected from 40 women undergoing ICSI, with gene expressions analyzed using specific assays.
- Results showed that certain Notch and Jagged proteins were significantly lower in PCOS patients, indicating a potential link to embryo quality, but more research is needed to confirm these findings.
Article Abstract
Purpose: The present study aimed to explore the associations between the expression pattern of molecules in the Notch pathway in the cumulus cells of polycystic ovary syndrome (PCOS) patients and the quality of zygotes and embryos.
Methods: A total of 200 cumulus complexes surrounding mature oocytes were obtained from 40 patients with and without PCOS undergoing intracytoplasmic sperm injection (ICSI). The expressions of Notch-1, Notch-2, and Notch-3 genes were examined by Reverse Transcription Q-PCR assay. Moreover, immunocytochemistry was performed for the expressions of Jagged-1 and Jagged-2 proteins. The correlations between the Notch receptors and their ligand expressions and the qualities of the zygote and embryo were investigated.
Results: The expression levels of Notch-2, Notch-3, Jagged-1, and Jagged-2 were significantly lower in patients with PCOS than in normal women (p < 0.05), while Notch-1 showed no meaningful difference between the groups. A positive correlation was found between Notch-1 and embryo quality. Furthermore, only Notch-2 and Jagged-2 marginally correlated with zygote quality.
Conclusion: The data of the present study indicated that evaluating the molecules in the Notch pathway in PCOS patients' cumulus cells provides a novel approach to predict the zygote and embryo quality. However, further studies on a larger population are needed to validate this finding.

The G protein-coupled estrogen receptor (GPER) plays a crucial role in various biological processes, but its regulation of oocyte meiosis remains unclear. In this study, we generated a Gper1 knockout in growing oocytes using Zp3-Cre, revealing that GPER is essential for oocyte maturation and embryo development. RNA-seq analysis indicated that GPER deficiency significantly altered the oocyte transcriptome and disrupted mRNA translation.

Background: The process of maturing ovine oocyte in vitro has not yet been raised with acceptable results.
Objective: This study was designed to evaluate the γ-oryzanol effect as a supplement of maturation media on the development of ovine oocytes to blastocyst.
Methods: Aspirated from ovine ovaries, morphologically normal cumulus-oocyte complexes (COCs) were matured in media supplemented with or without 5 µM γ-oryzanol.

Prolactin (PRL) plays a key role in the growth and ovulation of animal follicles, but its impact on follicular recruitment in ewes remains uncertain. In this study, a total of sixteen healthy ewes (Hu sheep, aged 2-3 years, with continuous reproduction and housed separately), matched for parity and weight (52.98 ± 0.

Lipids in cumulus-oocyte complexes are important actors in molecular signalling pathways and are influenced by maturation conditions. Acetyl-L-carnitine (ALC) is a carrier involved in fatty acid transport and is a promoter of β-oxidation. Although the embryonic development potential of oocytes can be improved when ALC is added to the maturation medium, the effects of ALC on the lipid content and composition of oocytes and cumulus cells remain unknown.

Polycystic ovary syndrome (PCOS) is the predominant cause of subfertility in reproductive-aged women; however, its pathophysiology remains unknown. Neurotensin (NTS) is a member of the gut-brain peptide family and is involved in ovulation; its relationship with PCOS is unclear. Here, we found that NTS expression in ovarian granulosa cells and follicular fluids was markedly decreased in patients with PCOS.
