Also, an increasing number of women are suffering from poor pregnancy outcome. However, the causal relationship between allergic asthma and embryonic growth in terms of cell morphogenesis has not been well elucidated. Here, we investigated the impact of allergic asthma on the morphogenesis of preimplantation embryos. Twenty-four female BALB/c were randomly divided into control (PBS), 50-μg (OVA1), 100-μg (OVA2) and 150-μg (OVA3). On Days-0 and -14, mice were induced intraperitoneally (i.p) with ovalbumin (OVA). On Days-21 until -23, mice were challenged with OVA via intranasal instillation (i.n). Control animals were sensitized and challenged with PBS. At the end of treatment (Day-25), 2-cell embryos were retrieved and cultured in vitro until the blastocysts hatched. Results showed reduced number of preimplantation embryos at all developing stages in all treated groups (p ≤ 0.0001). Uneven blastomere size, partial compaction- and cavitation-activity, low formation of trophectoderm (TE), as well as cell fragmentation were noted in all the treated groups. Maternal serum interleukin (IL)-4, immunoglobulin (Ig)-E and 8-hydroxydeoxyguanosine (8-OHdG) were notably high (p ≤ 0.0001, p ≤ 0.01) in contrast with low total antioxidant capacity (TAOC) (p ≤ 0.0001). Our findings indicated that OVA-induced allergic asthma had compromised cell morphogenesis through reduced blastomere cleavage division, partial compaction and cavitation-activity, impairment of TE production, and cell fragmentation leading to embryonic cell death via OS mechanism.","PeriodicalId":29860,"journal":{"name":"Cells & Development","volume":"1943 1","pages":"203864"},"PeriodicalIF":3.9,"publicationDate":"2023-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91204783","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}

We established Ccdc85c knockout (KO) rats and investigated the roles of CCDC85C and intermediate filament protein expression, including nestin, vimentin, GFAP, and cytokeratin AE1/AE3 during the lateral ventricle development in KO rats to evaluate the role of this gene. We found altered and ectopic expression of nestin and vimentin positive cells in the wall of the dorso-lateral ventricle in the KO rats during development from the age of postnatal day (P) 6, whereas both protein expression became faint in the wild-type rats. In the KO rats, there was a loss of cytokeratin expression on the surface of the dorso-lateral ventricle with ectopic expression and maldevelopment of ependymal cells. Our data also revealed disturbed GFAP expression at postnatal ages. These findings indicate that lack of CCDC85C disrupts the proper expression of intermediate filament proteins (nestin, vimentin, GFAP, and cytokeratin), and CCDC85C is necessary for normal neurogenesis, gliogenesis, and ependymogenesis.","PeriodicalId":29860,"journal":{"name":"Cells & Development","volume":"79 1","pages":"203858"},"PeriodicalIF":3.9,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79305322","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}
