Application of DNA marker related with marbling score in Hanwoo cow

Novel SNP in the coding region of the FTO gene is associated with marbling score in Hanwoo (Korean cattle)

The fat mass and obesity associated (FTO) gene plays an important role in the regulation of energy homeostasis, fat deposition and obesity. For this reason, the FTO gene is a physiological and functional candidate gene for carcass and meat quality traits in beef cattle. The objectives of this study were to identify SNPs in the exonic regions of FTO gene and to evaluate the association of these ...

Identification and analysis of phospholipid transfer protein polymorphisms and their association with marbling score in Hanwoo (Korean cattle).

Phospholipid transfer protein (PLTP) regulates high-density lipoprotein metabolism. The gene encoding PLTP is located on bovine chromosome 13. The objective of this study was to identify single nucleotide polymorphisms (SNPs) in the Hanwoo (Bos taurus coreanae) PLTP gene to detect novel mutations affecting economically important traits. Five SNPs were identified in the coding region (C7368T, G7...

Gene Co-expression Analysis to Characterize Genes Related to Marbling Trait in Hanwoo (Korean) Cattle

Marbling (intramuscular fat) is an important trait that affects meat quality and is a casual factor determining the price of beef in the Korean beef market. It is a complex trait and has many biological pathways related to muscle and fat. There is a need to identify functional modules or genes related to marbling traits and investigate their relationships through a weighted gene co-expression n...

Identification of marbling-related candidate genes in M. longissimus dorsi of high- and low marbled Hanwoo (Korean Native Cattle) steers.

This study was conducted to identify marbling-related candidate genes in M. longissimus dorsi of high- and low-marbled Hanwoo. The longissimus dorsi muscles were selected for gene expression from eight Hanwoo steer carcasses based on crude fat content. In the analysis of variance, gene expression of five candidate genes, FABP4, SCD, PPARgamma, Titin and Nebulin was determined to be significantl...
