Conversion of leucine to β‐hydroxy‐β‐methylbutyrate by α‐keto isocaproate dioxygenase is required for a potent stimulation of protein synthesis in L6 rat myotubes
BACKGROUND L-Leu and its metabolite β-hydroxy-β-methylbutyrate (HMB) stimulate muscle protein synthesis enhancing the phosphorylation of proteins that regulate anabolic signalling pathways. Alterations in these pathways are observed in many catabolic diseases, and HMB and L-Leu have proven their anabolic effects in in vivo and in vitro models. The aim of this study was to compare the anabolic e...
متن کاملHistological and biochemical evaluation of supplementing broiler diet with β-hydroxy-methyl butyrate calcium (β-HMB-Ca)
Two hundred and sixteen day-old Ross-308 broiler chicks were allocated into 4 groups to study the impacts of different concentrations (0.0, 0.1, 0.15 and 0.2%) of β-hydroxy-methyl butyrate calcium (β-HMB-Ca), on values of tri-iodothyronin (T3) and tetra-iodothyronin (T4) hormones, liver enzymes [aspartate aminotransferase (AST) and alanine aminotransferase (ALT)], uric acid, peroxide, malondial...
متن کاملBody composition of piglets from sows fed the leucine metabolite β-hydroxy β-methyl butyrate in late gestation.
Supplementation of the leucine metabolite β-hydroxy β-methyl butyrate (HMB) to sows during late gestation or lactation has been shown to improve piglet health, survival, and growth. This study aimed to investigate long-term effects of HMB supplementation to late-gestating sows on body characteristics of piglets at weaning. Sows were fed a standard lactation diet from day -15 relative to parturi...
متن کاملEffects of leucine and its metabolite β-hydroxy-β-methylbutyrate on human skeletal muscle protein metabolism
Maintenance of skeletal muscle mass is contingent upon the dynamic equilibrium (fasted losses-fed gains) in protein turnover. Of all nutrients, the single amino acid leucine (Leu) possesses the most marked anabolic characteristics in acting as a trigger element for the initiation of protein synthesis. While the mechanisms by which Leu is 'sensed' have been the subject of great scrutiny, as a br...
