Abstract
Adipokines play a crucial role in the regulation of energy homeostasis; however, little is known about genetic alterations in this family that may contribute to economic traits in cattle. Therefore, this study conducts transcript profiles, variations and association studies of three major adipokines, leptin (LEP), tumour necrosis factor (TNF) and angiopoietin-like protein 8 (ANGPTL8), to evaluate their effects on native Chinese cattle. Using quantitative real-time PCR, the study revealed that the bovine LEP was expressed primarily in the back and visceral fat, while TNF was predominantly expressed in spleen and ANGPTL8 was mainly expressed in back fat and liver. Five single nucleotide polymorphisms (SNPs) including two missense SNPs (SNP1: g.12254T>C and SNP2: g.14177C>T) in LEP, a synonymous SNP (SNP3: g.2130A>G) in TNF and two SNPs (SNP4: g.629G>A and SNP5: g.884T>C) in the 5'UTR of ANGPTL8 were identified and genotyped in 537 individuals from six Chinese cattle breeds. Bioinformatics analysis revealed that SNP1 might disrupt the efficient binding of LEP to its receptor, SNP3 might affect translation efficiency of TNF, and SNP4 and SNP5 were likely to affect stability, splicing and nuclear export of ANGPTL8 mRNA. Consistently, association studies indicated that three SNPs (SNP1, SNP3 and SNP5) were significantly associated with body weight, heart girth, average daily gain, hip width and body length in 100 Nanyang cattle (p < 0.05). Overall, our results support the view that LEP, TNF and ANGPTL8 could be used as biomarkers to improve the growth performance in Chinese cattle selection programmes.
