Interpretive Summary: ADIPOQ is a very important gene in cattle. This gene activity affects beef quality. This study demonstrated that a region of the genome has variable duplication. This duplication can decrease ADIPOQ gene activity. Association studies also confirm this duplication affects cattle growth and body measurements. Overall, his study provides valuable genetic information to explore the growth regulation of cattle.

Technical Abstract: The ADIPOQ gene of cattle, is located in the vicinity of the quantitative trait locus (QTL) wich effects marbling, the rib eye muscle area and fat thickness on BTA1. In our study, a novel variable duplication (NW_003103812.1:g.9232067_9232133 dup) in the bovine ADIPOQ promoter region was identified and genotyped in seven Chinese cattle breeds. Using a reporter assay, we demonstrated that g.9232067_9232133 dup decreased the basal transcriptional activity of the ADIPOQ gene in 3T3-L1 and C2C12 cells. Furthermore, g.9232067_9232133 dup suppressed the mRNA expression of the gene in adipose and muscle tissues. Association analysis indicated that the g.9232067_9232133 dup were associated with body measurements (P < 0.05).
