Estradiol (E2) administration can catalyze transformation from male to pseudo-female (PF), during which m6A RNA methylation undergoes considerable alterations. Nevertheless, the function of m6A methylation, specifically, the methyltransferase 14, N6-adenosine-methyltransferase non-catalytic subunit gene (<em>METTL14</em>) during this sex reversal process remains unclear. Within this study, we characterized the <em>METTL14</em> gene, which was predominantly expressed within the ovary and demonstrated notable expression in PF individuals. Interference of <em>METTL14</em> results in altered expression of methylation-related genes, yielding elevated <em>RSPO1</em> expression and diminished <em>AMH</em> expression. Administration of E2 and <em>METTL14</em>-RNAi elicits 7994 differentially expressed genes (DEGs) during sexual differentiation, and KEGG enrichment analysis highlighted that <em>METTL14</em> profoundly affects embryonic development through pathways including steroid hormone biosynthesis, ovarian steroidogenesis, tryptophan metabolism, and Glycolysis/Gluconeogenesis. Gene set enrichment analysis (GSEA) indicated that METTL14-RNAi triggers reduced expression of steroid hormone biosynthesis and ovarian steroidogenesis pathways while increasing the PPAR signaling pathway. In conclusion, METTL14-RNAi results in significant up-regulation of <em>RSPO1</em> and down-regulation of <em>AMH</em>, inducing substantial alterations in pathways associated with hormone and metabolism. These findings propose that <em>METTL14</em> may play a facilitating role during E2-induced sex reversal in <em>P. sinensis</em>, offering a novel avenue for further exploration into all-male breeding.</div></div>","PeriodicalId":12521,"journal":{"name":"Genomics","volume":"117 3","pages":"Article 111030"},"PeriodicalIF":3.4,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143624202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
