An increase in essential amino acid availability upregulates amino acid transporter expression in human skeletal muscle.
Essential amino acids (EAA) stimulate skeletal muscle mammalian target of rapamycin complex 1 (mTORC1) signaling and protein synthesis. It has recently been reported that an increase in amino acid (AA) transporter expression during anabolic conditions is rapamycin-sensitive. The purpose of this study was to determine whether an increase in EAA availability increases AA transporter expression in...
متن کاملAmino acid availability: aspects of chemical analysis and bioassay methodology.
It is important to be able to characterise foods and feedstuffs according to their available amino acid contents. This involves being able to determine amino acids chemically and the conduct of bioassays to determine amino acid digestibility and availability. The chemical analysis of amino acids is not straightforward and meticulousness is required to achieve consistent results. In particular a...
متن کاملAmino Acid Availability in Feedstuffs for the Growing Pig
Assessing amino acid (AA) availability in dietary ingredients is integral to the optimal formulation of diets both in terms of maximising nutrient utilization and profitability. Although the concept that nutrients in feedstuffs are not fully absorbed and metabolized by the animal is now widely accepted, a distinction needs to be made between the concepts of digestibility and availability. Diges...
متن کاملDevelopment of an amino acid composition database and estimation of amino acid intake in Japanese adults.
Investigations of the association between an individual's habitual amino acid intake and several types of health outcome require a comprehensive amino acid composition database. The lack of a database of the amino acid content of foods routinely consumed makes estimating daily amino acid intake difficult. The aim of this study was to develop an amino acid database for use in epidemiological stu...
متن کاملEffects of Sodium and Amino Acid Substrate Availability upon the Expression and Stability of the SNAT2 (SLC38A2) Amino Acid Transporter
The SNAT2 (SLC38A2) System A amino acid transporter mediates Na+-coupled cellular uptake of small neutral α-amino acids (AAs) and is extensively regulated in response to humoral and nutritional cues. Understanding the basis of such regulation is important given that AA uptake via SNAT2 has been linked to activation of mTORC1; a major controller of many important cellular processes including, fo...
