Association of CRTC2 gene polymorphisms with growth and meat quality traits of Qinchuan cattle

H. C. Xu, Gui, L. S., Song, N., Zhang, Y. Y., .C.Wang, H., and Zan, L. S., Association of CRTC2 gene polymorphisms with growth and meat quality traits of Qinchuan cattle, vol. 14, pp. 12912-12920, 2015.

Growth and meat quality traits play important roles in the evaluation of cattle productivity and are influenced by genetic and environmental factors. CRTC2 is a recently discovered gene related to obesity that may influence fat deposition. The aim of the current study was to detect polymorphisms of bovine CRTC2 and explore their relationships to growth and meat quality in Qinchuan cattle. Three single nucleotide polymorphisms (SNPs); g.3001 C>T; g.3034 G>A; and g.3467 T>C, were identified from sequencing results of 422 Qinchuan cattle.

Genetic polymorphisms of the FATP1 gene and their associations with meat quality traits in Chinese Qinchuan cattle

Fatty acid transport protein 1 (FATP1), an integral membrane protein that facilitates long-chain fatty acid influx, is involved in the genetic network for oleic acid synthesis. The aim of this study was to examine the association of FATP1 polymorphisms with live animal meat quality traits in Chinese Qinchuan cattle. Quantitative real-time PCR analysis demonstrated that FATP1 has a broad tissue distribution in Qinchuan cattle and is highly expressed in longissimus dorsi muscle and back fat.

Polymorphisms in the bovine CIDEC gene are associated with body measurement traits and meat quality traits in Qinchuan cattle

C. G. Mei, Gui, L. S., Fu, C. Z., Wang, H. C., Wang, J. L., Cheng, G., and Zan, L. S., Polymorphisms in the bovine CIDEC gene are associated with body measurement traits and meat quality traits in Qinchuan cattle, vol. 14, pp. 9013-9023, 2015.

Previous studies have shown that the cell death-inducing DFF45-like effector-C (CIDEC) gene is involved in lipid storage and energy metabolism, suggesting that it is a potential candidate gene that affects body measurement traits (BMTs) and meat quality traits (MQTs). The aim of this study was to identify polymorphisms of the bovine CIDEC gene and analyze their possible associations with BMTs and MQTs in 531 randomly selected Qinchuan cattle aged between 18 and 24 months.
