In the present study the hspa6 gene was expressed more in animals with a high marbling score.
Marbling gene expression.
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.
R 0 72 p value 0 013 dpyd.
The pearson s correlation coefficients of marbling and two gene s expression levels are highly correlated and also statistically significant by regression analysis tmem60.
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.
Fatty acid gene expression lipids lipogenesis membrane transporters implications.
In a gene expression study using blood cells from obese and normal weight humans this gene was expressed more in obese subjects.
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.
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.
How it relates to marbling.
R 0 85 and p value 0 001.
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.
In this sense the review focuses in two phases.
When the jumping gene leaves the compromised melanin producing gene in the growing fish melano production resumes creating a dark patch.
We confirmed many findings previously made at the biochemical level and made new discoveries.
Therefore we identified candidate genes associated with marbling and then confirmed candidate genes in imf.
Scd1 gene expression in lt muscle was positively correlated with lpl and fabp4 expression showing that the expression of scd1 in muscle tissue is directly related to mechanisms including the breakdown of triglycerides by lipoprotein lipase and the transport of fatty acid molecules to adipocytes by the fabp4 pathway jurie et al 2007.
Intramuscular fat imf in cattle is an important component of traits that influence meat quality.
To find the candidate gene associated with marbling we used a weighted gene coexpression network analysis from the.
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.
Differences were found in adipogenic gene expression including fabp4 rxr rxr and raldh1α1 p 0 05.
