Variation in free fatty acids ( ) and insulin ( ) concentrations in response to meals in healthy people (upper panel, reprinted from Frayn KN, 1998) [6] and fatty acid levels in mild essential hypertensive patients (---) and normotensive control subjects (——) (lower panel, reprinted from Singer P et al. 1985) [5]. 2015-03-13 · The exocyst is an octameric molecular complex that drives vesicle trafficking in adipocytes, a rate-limiting step in insulin-dependent glucose uptake. This study assessed the role of the exocyst complex in regulating free fatty acid (FFA) uptake by adipocytes. Upon differentiating into adipocytes, 3T3-L1 cells acquire the ability to incorporate extracellular FFAs in an insulin-dependent manner It is well known that excessed fatty acid accumulation in peripheral tissue with high metabolic active may cause metabolic dysregulation of glucose, known as insulin resistance due to glucose fatty-acid cycle, and the previous study has shown that glucose transporter type 4 (GLUT4), a rate-limiting factor for glucose uptake, in mice skeletal muscle is decreased by long-term high-fat diet (Koh The rapid rise in the prevalence of obesity and diabetes has significantly contributed to the increasing global burden of noncommunicable diseases.

2015-09-29 · Insulin resistance is a multi-faceted disruption of the communication between insulin and the interior of a target cell. The underlying cause of insulin resistance appears to be inflammation that can either be increased or decreased by the fatty acid composition of the diet.

Consumption of specific dietary fatty acids has been shown to influence risk Obesity and insulin resistance are associated with chronic, low grade inflammation. fat by inhibiting fatty acid uptake into mesenteric lymph node macrophages.

Propionic acid and butyric acid are also able to potentiate insulin-stimulated glucose uptake.

Initially fatty acids potentiate the effects of glucose.

Consistent with this model, overexpression of MCD in liver of high-fat–fed rats resolves hepatic steatosis and lowers circulating fatty acid levels while reversing insulin resistance . In contrast, high-fat feeding actually increases rather than decreases β-oxidation in muscle due to transcriptional activation of the pathway and increased substrate supply ( 9 ).

Fatty acids may act directly upon the pancreatic β-cell to regulate glucose-stimulated insulin secretion. This effect is biphasic. Initially fatty acids potentiate the effects of glucose.

The goal of the present study was to test the hypothesis that this single role of insulin is insufficient to explain observed fatty acid dynamics. Insulin also reduced [3H]oleic acid uptake up to 35%, depending on insulin concentration and decreased the amount of fatty acid esterified into the phospholipids and neutral lipids by 28 and 70%, respectively. In contrast, glucagon or epinephrine stimulated both the initial rate and extent of cis-parinaric acid uptake 18 and 25%, respectively. 1. Insulin promotes synthesis of fatty acids in the liver.
