The determination of cysteine and homocysteine levels is great current interest for the monitoring desease states. A new colorimetric method simultaneous detection l-cysteine l-homocysteine has been developed. fluorescein derivative reacts with above amino acids, producing their respective thiazolidines resulting in color changes. Interference from other acids proteins minimal.

Cardiac metabolic remodeling is a central event during heart failure (HF) development following myocardial infarction (MI). It well known that glucose and fatty acid dysmetabolism contribute to post-MI cardiac dysfunction remodeling. However, the role of amino metabolism in HF remains elusive. Branched chain acids (BCAAs) are an important group essential function as crucial nutrient signaling mammalian animals. The present study aimed determine BCAA progression. Utilizing coronary artery...

The Western meat-rich diet is both high in protein and fat. Although the hazardous effect of a fat (HFD) upon liver structure function well recognized, whether co-presence intake contributes to, or protects against, HF-induced hepatic injury remains unclear. Increased branched chain amino acids (BCAA, essential compromising 20% total intake) reduces body weight. However, elevated circulating BCAA associated with non-alcoholic fatty disease injury. mechanisms responsible for this quandary...

The branched-chain amino acids (BCAA) accumulated in type 2 diabetes are independent contributors to insulin resistance. activity of α-keto acid dehydrogenase (BCKD) complex, rate-limiting enzyme BCAA catabolism, is reduced diabetic states, which contributes elevated concentrations. However, the mechanisms underlying decreased BCKD remain poorly understood. Here, we demonstrate that mitochondrial phosphatase 2C (PP2Cm), a newly identified increases activity, was significantly downregulated...

Either insufficient or excessive autophagy causes cellular death and contributes to myocardial ischaemia/reperfusion (I/R) injury. However, mechanisms controlling the 'right-level' of in heart remains unidentified. Thioredoxin-interacting protein (TXNIP) is a pro-oxidative molecule knowing contribute I/R whether how TXNIP may further inhibit suppressed promote cardiac has not been previously investigated.Wild type gene-manipulated adult male mice were subjected I/R. was increased myocardium...

Branched chain amino acids (BCAAs) are associated with the progression of obesity-related metabolic disorders, including type 2 diabetes and nonalcoholic fatty liver disease. However, whether BCAAs disrupt homeostasis hepatic glucose lipid metabolism remains unknown. In this study, we observed that supplementation significantly reduced high-fat (HF) diet–induced accumulation while increasing plasma levels promoting muscular renal accumulation. Further studies demonstrated increased...

As the essential amino acids, branched-chain acid (BCAA) from diets is indispensable for health. BCAA supplementation often recommended patients with consumptive diseases or healthy people who exercise regularly. Latest studies and ours reported that elevated level was positively correlated metabolic syndrome, diabetes, thrombosis heart failure. However, adverse effect of in atherosclerosis (AS) its underlying mechanism remain unknown. Here, we found plasma an independent risk factor CHD by...

Recent studies show branched-chain amino acid (BCAA) catabolic pathway is defective in obese animals and humans, contributing to the pathogenesis of insulin resistance diabetes. However, context obesity, various processes including dysfunctional lipid metabolism can affect sensitivity glycemic regulation. It remains unclear how BCAA defect may exert direct impacts on glucose without disturbance obesity. The current study characterized lean mice which genetic deletion PP2Cm leads moderate...

The advanced glycation end products (AGEs) are associated with increased cardiac endothelial injury. However, no causative link has been established between AGEs and enhanced injury after ischemia/reperfusion. More importantly, the molecular mechanisms by which may increase remain unknown. Adult rat microvascular cells (CMECs) were isolated incubated AGE-modified bovine serum albumin (BSA) or BSA. After AGE-BSA BSA preculture, CMECs subjected to simulated ischemia (SI)/reperfusion (R). SI/R...

Adipose-derived stem cells (ADSCs) have the ability to migrate injury sites and facilitate tissue repair by promoting angiogenesis. However, therapeutic effect of ADSCs from patients with diabetes is impaired due oxidative stress.
