However, chromosome aberrations are common during early mammalian embryogenesis. Chromosomal abnormalities during the early stages of embryogenesis result in the formation of mosaic embryos, wherein cells with normal genomes coexist with cells exhibiting abnormal genomes. The precise frequency and etiology of such abnormalities remain unclear. It is postulated that these aberrations contribute to the etiology of a number of conditions, including infertility and congenital diseases such as Down's syndrome.Methods: This review synthesizes current literature and data to elucidate the causes and implications of chromosome aberrations in early mammalian embryos. It places particular emphasis on identifying patterns of mosaicism and investigating the underlying mechanisms responsible for these abnormalities.Main findings: The underlying causes of chromosome abnormalities in early embryos were examined in the context of DNA replication and embryonic development.Conclusion: A deeper understanding of chromosome abnormalities in early embryos could help develop new infertility treatments and advance research on cancers caused by these abnormalities.

These changes were associated with a decrease in the recruitment of BUBR1 to kinetochores at M I stage, but there were no differences in the expression of REC8 between the two genotypes. Furthermore, the addition of L-ascorbic acid (AsA) or N-acetyl-L-cysteine (NAC) during IVM reduced the frequency of chromosome segregation errors in Sod1KO oocytes.Conclusions: Oxidative stress caused by Sod1 deficiency during IVM impairs the spindle assembly checkpoint function due to a decrease in the recruitment of BUBR1 to M I stage kinetochores, leading to abnormalities in meiotic progression and chromosome segregation.","PeriodicalId":21116,"journal":{"name":"Reproductive Medicine and Biology","volume":"24 1","pages":"e12622"},"PeriodicalIF":2.7,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11751902/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143024482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, immunotherapies focusing on modulating uNK cell function have been controversial in terms of pregnancy outcomes.

Accumulating evidence suggests that LDs not only store neutral lipids but also coordinate with other organelles for lipid metabolism within cells.Methods: This review focuses on the synthesis of LDs during follicular development and highlights the factors involved in the regulation of LD biogenesis within the ovary.Main findings: In the mammalian ovary, the presence of LDs has long been recognized mainly by morphological analysis. However, their distribution in the ovary varies according to the region and cell type; for example, LDs are abundant in the medulla, which has a rich blood vessel network, in interstitial cells, which are the site of steroid production, and surrounding growing follicles, while they are poor in granulosa cells within follicles. LDs are also enriched in the corpus luteum after ovulation and massively accumulate in atretic follicles during follicular growth. Furthermore, LD synthesis is synchronized with angiogenesis during follicular development.Conclusion: Addressing the functional link between LD biogenesis and angiogenesis is essential for understanding the molecular basis underlying LD biology, as well as the ovarian dysfunction with metabolic disorders.","PeriodicalId":21116,"journal":{"name":"Reproductive Medicine and Biology","volume":"23 1","pages":"e12618"},"PeriodicalIF":2.7,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11646352/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142829602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Differentially expressed genes (DEGs) were filtered based on predominant expression in spermatids and gene functional annotations relevant to sperm morphology and motility.
