The second intron of IGF2BP1 has been implicated in growth-related traits, though its precise mechanistic role remains elusive. Initial resequencing analyses in our laboratory indicated strong selective pressures on the IGF2BP1 genomic region, prompting the selection and identification of several single nucleotide polymorphisms (SNPs). Seven SNPs were mapped to the conserved region of the second intron, necessitating further investigation into their functional relevance and association with growth traits. In this study, 348 Nanjiang Yellow goats were analyzed, and the association analysis via the GLM program in SAS 9.4 identified five SNPs significantly correlated with growth traits. Notably, rs652062749(A > G) emerged as a critical locus influencing later-stage growth traits. Furthermore, strong linkage disequilibrium was observed among three SNPs, with the rs638185407 (T > A) variant markedly enhancing luciferase activity in H293T cells. Combination genotypes TTAACT, TTCCCC, and ATCACT were identified as superior for growth traits, offering theoretical insights for genetic co-breeding. This study underscores the potential utility of IGF2BP1 as a functional genetic marker in Nanjiang Yellow goat breeding programs.","PeriodicalId":7836,"journal":{"name":"Animal Biotechnology","volume":"36 1","pages":"2461176"},"PeriodicalIF":1.7,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cell counting and flow cytometry revealed that TERT-transfected cells had higher viability and lower apoptosis rates compared to SSF (P < 0.05). Karyotype and soft agar colony formation assays indicated that hTERT and sTERT-transfected cells maintained normal characteristics without malignant transformation. β-galactosidase staining indicated that TERT transfection significantly reduced cellular senescence (P < 0.001). Additionally, sTERT-transfected cells exhibited higher TERT expression, enhanced viability, proliferation, and anti-senescence effects compared to hTERT-transfected cells (P < 0.05).

This study examined the association between ZP3 gene variations and LS in Kari sheep. Two groups of 160 Kari ewes were analysed: one consistently producing singletons and another producing twins, with occasional triplets. Additionally, Madakhlasht sheep, which sometimes produce twins, and Balkhi sheep, which produce only singletons, were used as references. The entire ZP3 gene was amplified using PCR and sequenced at 30× with Next Generation Sequencing. Bioinformatics analysis identified 70 variants across the three breeds, located in upstream regions, introns, and exons. Notably, two point mutations and a six-nucleotide insertion were found upstream of the initiation codon in twin-producing Kari ewes, potentially affecting ZP3 expression and LS. Two missense mutations (I101L in exon 1 and R408H in exon 8) were heterozygous in twin-producing Kari ewes but homozygous in other groups, correlating with LS. Protein modelling suggested that the I101L mutation alters the binding site, potentially impacting protein function. These findings indicate that ZP3 gene variations influence reproductive efficiency and LS in sheep, with specific variants serving as potential markers for selective breeding to enhance LS.","PeriodicalId":7836,"journal":{"name":"Animal Biotechnology","volume":"36 1","pages":"2450364"},"PeriodicalIF":1.7,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the livestock sector adapts to contemporary needs, the increasing global demand for animal products, fueled by population growth, highlights the significance of effective breeding techniques. Growth and meat traits are a key factor in sheep breeding, directly impacting resource efficiency and breeder profitability. In this review, we have explored the advantages of molecular marker-assisted selection (MAS) and its specific applications in breeding meat sheep. We summarized research on quantitative trait loci (QTLs) and genome-wide association studies (GWAS), as well as variations in key genes, including myostatin (MSTN), insulin-like growth factor 1 (IGF-1), and calpastatin (CAST), associated with growth, meat quality, and carcass traits in sheep. The advancements in molecular breeding for meat sheep, along with improvements in sheep genetics, genomic selection, and genome editing, have enhanced our understanding of DNA markers and demonstrated the genetic diversity present in meat sheep, significantly enriching sheep breeding strategies. Improvements in sample size, phenotyping efficiency, and the integration of omics studies could enhance our understanding of gene interactions, enabling MAS technology to reach its full potential.","PeriodicalId":7836,"journal":{"name":"Animal Biotechnology","volume":"36 1","pages":"2526458"},"PeriodicalIF":1.7,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144590291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
