Marbling Gene Expression

Therefore we identified candidate genes associated with marbling and then confirmed candidate genes in imf.

Marbling gene expression.

In conclusion the knowledge shows that gene expression is a metabolic factor affecting marbling and fatty acid profile in ruminant meat and diets and their nutrients have direct effect on how these genes are expressed. We measured carcass characteristics and gene expression in korean steers to clarify the molecular mechanism s underlying imf deposition in lm tissue by determining the correlation between imf content and gene expression abundance and by developing models to predict imf content using gene. Between breed and treatment on marbling score p 0 008 angus cross steers on the low vit a had the greatest marbling and resultantly the greatest quality grades p 0 02. The pearson s correlation coefficients of marbling and two gene s expression levels are highly correlated and also statistically significant by regression analysis tmem60.

Marbling is an important trait in characterization beef quality and a major factor for determining the price of beef in the korean beef market. To find the candidate gene associated with marbling we used a weighted gene coexpression network analysis from the. The present review will present the recent published results and discuss the main effects of nutrients mainly fatty acids on the expression of genes involved in lipid metabolism. Differences were found in adipogenic gene expression including fabp4 rxr rxr and raldh1α1 p 0 05.

When the jumping gene leaves the compromised melanin producing gene in the growing fish melano production resumes creating a dark patch. In particular marbling is a complex trait and needs a system level approach for identifying candidate genes related to the trait. In a gene expression study using blood cells from obese and normal weight humans this gene was expressed more in obese subjects. How it relates to marbling.

Later in the fish s growth the jumping gene is reinserted affecting the melanin production of a smaller group of cells creating an inner light spot in the dark patch. R 0 85 and p value 0 001. This study used a genome wide screen of gene expression to better understand the metabolic and functional differences between commercially valuable intramuscular fat imf and commercially wasteful subcutaneous sc fat depots in bos taurus beef cattle. In the present study the hspa6 gene was expressed more in animals with a high marbling score.

R 0 72 p value 0 013 dpyd. Fatty acid gene expression lipids lipogenesis membrane transporters implications. We confirmed many findings previously made at the biochemical level and made new discoveries. In this sense the review focuses in two phases.
