Peroxisome proliferator-activated receptor (PPAR) γ coactivator 1α (PGC-1α) is a coactivator of various nuclear receptors and other transcription factors, which is involved in the regulation of energy metabolism, thermogenesis, and other biological processes that control phenotypic characteristics of various organ systems including skeletal muscle. PGC-1α in skeletal muscle is considered to be ...
PURPOSE The effect of BCAA (branched chain amino acid) administration on muscle atrophy during growth phases is not well known. We investigated whether BCAA administration can prevent the muscle atrophy induced by hindlimb suspension in growing male rats. METHODS Male Wistar rats were assigned to 1 of 2 groups (n = 7/group): hindlimb suspension and hindlimb suspension with oral BCAA administr...
Elevated blood branched-chain amino acids (BCAA) are often associated with insulin resistance and type 2 diabetes, which might result from a reduced cellular utilization and/or incomplete BCAA oxidation. White adipose tissue (WAT) has become appreciated as a potential player in whole body BCAA metabolism. We tested if expression of the mitochondrial BCAA oxidation checkpoint, branched-chain α-k...
BCAA catabolism in skeletal muscle is regulated by the branched-chain alpha-keto acid dehydrogenase (BCKDH) complex, located at the second step in the BCAA catabolic pathway. The activity of the BCKDH complex is regulated by a phosphorylation/dephosphorylation cycle. Almost all of BCKDH complex in skeletal muscle under normal and resting conditions is in an inactive/phosphorylated state, which ...
The Western meat-rich diet is both high in protein and fat. Although the hazardous effect of a high fat diet (HFD) upon liver structure and function is well recognized, whether the co-presence of high protein intake contributes to, or protects against, HF-induced hepatic injury remains unclear. Increased intake of branched chain amino acids (BCAA, essential amino acids compromising 20% of total...
The effects of branched-chain amino acid (BCAA) supplementation on the lactate threshold (LT) were investigated as an index of endurance exercise capacity. Eight trained male subjects (21+/-2 y) participated in a double-blind crossover placebo-controlled study. The subjects were randomly assigned to two groups and were provided either a BCAA drink (0.4% BCAA, 4% carbohydrate; 1,500 mL/d) or an ...
The prevention of hepatic encephalopathy by the intravenous infusion of a branched chain amino acid (BCAA)-enriched solution was investigated in methionine and ammonium acetate-treated rats whose liver was already injured with carbon tetrachloride. A BCAA-enriched solution protected the rats from entering a coma. The brain BCAA contents became higher, and the brain methionine and tyrosine level...
BACKGROUND The purpose of this study is to investigate the effects of intraoperative infusion of branched-chain amino acids (BCAA) in patients undergoing gastrointestinal tumor surgery. METHODS Sixty-one patients with gastrointestinal tumors undergoing gastrointestinal surgery were enrolled and randomly assigned to receive an intraoperative infusion of 3-compound BCAA solution (N = 20), amino...
Administration of branched-chain amino acids (BCAA) has been reported to improve liver function, quality of life (QOL). However, in some malnourished patients, serum albumin levels do not improve in response to BCAA granules. In this study, we examined the effects of BCAA-enriched enteral nutrition in patients unresponsive to BCAA granules. Thirty-two decompensated cirrhotic patients at Osaka M...
KEY POINTS • Branched-chain amino acids (BCAA) are essential amino acids (EAA) that play several important roles in muscle metabolism. • The BCAA – especially leucine – are critical for stimulation of molecular signaling that leads to muscle protein synthesis and muscle protein breakdown. However, there is no research that has assessed the response of muscle protein synthesis to BCAA (or leucin...
