Fatty acids and gene transcription

Regulation of gene transcription by fatty acids.

Dietary fat is well recognised as an important macronutrient that has major effects on growth, development and health of all animals including humans. The amount and type of fat in the diet impacts on many aspects of metabolism including lipoprotein pathways, lipid synthesis and oxidation, adipocyte differentiation and cholesterol metabolism. It has become increasingly apparent that many of the...

The Association of Omentin Gene Expression in Visceral and Subcutaneous Adipose Tissues with Plasma Fatty Acids Profile and Dietary Fatty Acids

Introduction: Omentin, an adipokine, with anti-inflammatory effects reduces insulin resistance, and can hence, play an important role in prevention of cardiovascular disease and diabetes. The present study aimed to investigate the association of plasma and dietary fatty acids with gene expression of omentin in visceral and subcutaneous adipose tissues. Materials and Methods: Visceral and subcut...

Polyunsaturated fatty acids inhibit S14 gene transcription in rat liver and cultured hepatocytes.

Polyunsaturated fatty acids (PUFAs) have been shown to have significant effects on hepatic lipogenic gene expression. The S14 gene has been used as a model to examine the effects of PUFAs on hepatic lipogenic gene expression. In vivo studies showed that feeding rats a high carbohydrate diet containing menhaden oil rapidly (within hours) and significantly (> or = 50%) attenuates hepatic S14 gene...

Circulating n-3 fatty acids and trans-fatty acids, PLA2G2A gene variation and sudden cardiac arrest.

Whether genetic factors influence the associations of fatty acids with the risk of sudden cardiac arrest (SCA) is largely unknown. To investigate possible gene-fatty acid interactions on SCA risk, we used a case-only approach and measured fatty acids in erythrocyte samples from 1869 SCA cases in a population-based repository with genetic data. We selected 191 SNP in ENCODE-identified regulatory...
