Insulin infusion lowered levels of most amino acids in both groups. Insulin treatment did not significantly affect the uptake or release of amino acids. Significant net uptake of branched-chain amino acids was noted in both groups, as well as uptake of lysine and phenylalanine in the IDDM subjects.
Increased conversion of amino acids to glucose - Enhanced triglycerid lipolysis - Enhanced amino acid uptake - Stimulation of insulin secretion - Enhanced
1993-08-01 · By using an amino acid clamp Abumrad and coworkers have recently demonstrated that insulin resistance in glucose metabolism is enhanced by amino acids (24). On the other hand amino acid infusion increases the action of insulin on protein metabolism in fasting (25) thereby decreasing proteolysis. resulted in no inhibition of amino acid uptake (Table I). Insulin (0.4 unit per ml) stimulated uptake a-fold under these conditions and this stimulation was not impaired by puromycin. Quite different results were seen when the preincubation period was lengthened to 3 hours (Fig.

Diabetesbehandling – från insulin till transplantationer It links amino acids into proteins according to the messenger RNA (mRNA) instructions. in all eukaryotes and functions in processes ranging from nutrient uptake to cell-cell signaling. av M Menna · 2013 · Citerat av 60 — Amino- and amino acid- substituted quinone containing meroterpenes. glucose uptake in 3T3-L1 cells, and showed strong insulin-sensitizing activities.

In addition to insulin's effect on entry of glucose into cells, it also stimulates the uptake of amino acids, again contributing to its overall anabolic effect. When insulin levels are low, as in the fasting state, the balance is pushed toward intracellular protein degradation.
PPAR gamma (adipose tissue): insulin sensitization, glucose lowering, lipid lowering is a balance between uptake and release of fatty acids to/from the adipose tissue. The fat cells had access to glucose and amino acids.
Insulin switched forearm amino acid exchange from a net output (-2,630 +/- 1,100 nmol/min per kig of forearm tissue) to a net uptake (1,610 +/- 600 nmol/min per kg, P < 0.01 vs baseline). Other substances known to stimulate insulin release include the amino acids arginine and leucine, parasympathetic release of acetylcholine (acting via the phospholipase C pathway), sulfonylurea, cholecystokinin (CCK, also via phospholipase C), and the gastrointestinally derived incretins, such as glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP).
Significant net uptake of branched-chain amino acids was noted in both groups, as well as uptake of lysine and phenylalanine in the IDDM subjects. Insulin significantly increased the ileal uptake of valine, isoleucine, leucine, tyrosine, threonine, and serine from arterial blood: uptake of these amino acids was approximately doubled 45 min after the end of the insulin infusion. Insulin had no effect on glucose uptake or release. The effect of PLO on insulin absorption was also examined in in-vivo pulmonary administration in rats, and co-administration of PLO enhanced the hypoglycemic action of insulin. These findings suggest that co-administration of poly(amino acid)s such as PLO is a useful strategy for enhancing insulin uptake by alveolar epithelial cells and subsequent absorption from the lung. Insulin triggers the uptake of glucose, fatty acids and amino acids into liver, adipose tissue and muscle and promotes the storage of these nutrients in the form of glycogen, lipids and protein respectively. Failure to uptake and store nutrients results in diabetes.

The insulin is secreted to stimulate protein synthesis--the uptake of amino acids into muscle cells--making them less available for gluconeogenesis. The glucagon is secreted to stimulate the uptake of amino acids into the cells of the liver for gluconeogenesis. So why are these two hormones battling for opposing uses of the same amino acids?

resulted in no inhibition of amino acid uptake (Table I). Insulin (0.4 unit per ml) stimulated uptake a-fold under these conditions and this stimulation was not impaired by puromycin. Quite different results were seen when the preincubation period was lengthened to 3 hours (Fig. 1). Puromycin reduced AIB uptake by 40% in the absence of insulin
After a pure protein meal, the increased levels of dietary amino acids reaching the pancreas stimulate the release of glucagon above fasting levels, thereby increasing amino acid uptake into the liver. Two experiments were conducted to measure the effect of level of feed intake on net amino acid absorption by portal-drained viscera of six beef heifers with catheters in a mesenteric vein, portal vein and iliac artery (Exp. 1) and to evaluate intrajugular infusion of insulin or glucose on amino acid uptake by hind half of four beef steers with catheters in posterior aorta and vena cava (Exp. 2).
