In this study, we aimed to analyze the distinct contributions of Dnmt1 and Dnmt3a enzymes in oocyte maturation, survival, autophagy, reactive oxygen species (ROS) production, and compensation capacity of Dnmt3b and Dnmt3l enzymes in mouse oocytes. Following confirming the suppression of Dnmt1or Dnmt3a through siRNA application, the assessment involved immunofluorescence staining for Dnmts, 5mC, p62, and ROS levels. Cell death rates showed a noticeable increase while oocyte maturation rates exhibited significant reduction. Global DNA methylation showed a decline, concomitant with elevated p62 and ROS levels upon Dnmt1 or Dnmt3a knockdown. Remarkably, silencing of Dnmt1 led to an upsurge in Dnmt3a expression, whereas Dnmt3a knockdown triggered an increase in Dnmt1 levels. Furthermore, Dnmt3l expression exhibited a notable decrease after silencing of either Dnmt1 or Dnmt3a, while Dnmt3b levels remained comparable between control and siRNA-treated groups. Collectively, this study underscores the pivotal roles of Dnmt1 and Dnmt3a in orchestrating various facets of oocyte development, encompassing maturation, survival, autophagy, and ROS production. These findings offer valuable insights into the intricate regulatory network governed by DNA methylation machinery within the context of oocyte physiology.\u0000 </div>","PeriodicalId":12718,"journal":{"name":"genesis","volume":"62 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138177657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In embryos, however, bop1 mRNA is highly enriched in the neural plate, cranial neural crest and placodes, and potentially may interact with Six1, which also is expressed in these tissues. Recent work demonstrated that during development, Bop1 is required for establishing the size of the tadpole brain, retina and cranial cartilages, as well as controlling neural tissue gene expression levels. Herein, we extend this work by assessing the effects of Bop1 knockdown at neural plate and larval stages. Loss of Bop1 expanded neural plate gene expression domains (sox2, sox11, irx1) and reduced neural crest (foxd3, sox9), placode (six1, sox11, irx1, sox9) and epidermal (dlx5) expression domains. At larval stages, Bop1 knockdown reduced the expression of several otic vesicle genes (six1, pax2, irx1, sox9, dlx5, otx2, tbx1) and branchial arch genes that are required for chondrogenesis (sox9, tbx1, dlx5). The latter was not the result of impaired neural crest migration. Together these observations indicate that Bop1 is a multifunctional protein that in addition to its well-known role in ribosomal biogenesis functions during early development to establish the craniofacial precursor domains.\u0000 </div>","PeriodicalId":12718,"journal":{"name":"genesis","volume":"62 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136399934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
