Lire la suite >The lipase E hormone-sensitive (LIPE) enzyme is one of the lipolytic enzymes, and it plays a key role in the regulation of adipose tissue deposition. This study was conducted to investigate the possible association between the LIPE gene variations and the main body weight measurements in Awassi sheep. A total of 160 of sexually mature Awassi rams (Ovis aries) that aged between 2 and 3 years were included in the present study. Genomic DNA was extracted and two specific PCR amplicons were designed to amplify two coding regions within the LIPE gene. Genotyping experiments were performed using polymerase chain reaction-single-strand conformational polymorphism (PCR-SSCP). Two different SSCP banding patterns were identified, CC and CD in exon 2, and AA and AT in exon 9. Five novel single-nucleotide polymorphisms (SNPs) were detected by sequencing, namely g.151C > A and g.198C > T in exon 2, and g.213G > C, g.226G > T, and g.232A > C in exon 9. Haplotype block analysis showed strong linkage disequilibrium values between the two SNPs in exon 2 and the three SNPs in exon 9. Association analysis of haplotypes with carcass traits demonstrated a significantly higher dressing percentage (P < 0.05) and lower fat tail weight (FTW) in CACT and GCGTAC haplotypes made these haplotypes more favorable for human consumption. The current research is the first one to report a tight association between the LIPE genetic polymorphism and the dressing percentage and FTW traits, suggesting a pivotal role played by these co-inherited SNPs in the metabolism of carcass traits in sheep.Lire moins >
