Here, we report that zinc finger protein ZCCHC8-a key component of the nuclear exosome targeting (NEXT) complex that is involved in ribonucleic acid (RNA) surveillance-is required for TE silencing during spermatogenesis. Loss of ZCCHC8 results in delayed meiotic progression and reduced production of round spermatids (RS). We observed that young long-interspersed nuclear element (LINE1, L1) subfamilies that are targeted by ZCCHC8 were upregulated in both spermatogonial stem cells (SSC) and pachytene spermatocytes (PS) of Zcchc8 null testes. Further study found that a reduced H3K9me3 modification in SSC and elevated H3 lysine 4 trimethylation in the PS of Zcchc8 KO mice occurred upon young L1, especially L1Md_A, which may have contributed to impairment of the chromatin condensation from PS to RS during spermatogenesis. This study highlights the crucial role of RNA surveillance-mediated chromatin repression by the NEXT complex during spermatogenesis.","PeriodicalId":18842,"journal":{"name":"National Science Review","volume":"12 1","pages":"nwae407"},"PeriodicalIF":16.3,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11697976/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this linear relationship with a uniform EF5r is poorly constrained, which impedes the N2O estimation and mitigation. Our meta-analysis discovered a universal N2O emission baseline (EF5r = k/[NO3 -], k = 0.02) for natural rivers. Anthropogenic impacts caused an overall increase in baselines and the emergence of hotspots, which constitute two typical patterns of anthropogenic sources. The k values of agricultural and urban rivers increased to 0.09 and 0.05, respectively, with 11% and 14% of points becoming N2O hotspots. Priority control of organic and NH4 + pollution could eliminate hotspots and reduce emissions by 51.6% and 63.7%, respectively. Further restoration of baseline emissions on nitrate removal is a long-term challenge considering population growth and declining unit benefits (ΔN-N2O/N-NO3 -). The discovery of EF lines emphasized the importance of targeting hotspots and managing baseline emissions sustainably to balance social and environmental benefits.","PeriodicalId":18842,"journal":{"name":"National Science Review","volume":"12 2","pages":"nwae458"},"PeriodicalIF":16.3,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11745158/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143008141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
