Carbohydrate-rich meals are used as a late evening snack in cirrhotic patients, but our study indicates that supplementation with a BCAA mixture can also be used to reduce fat oxidation in the early morning, with results similar to those with carbohydrate-rich snacks.
DELLA proteins act as negative regulators in gibberellin (GA) signal transduction. GA-induced DELLA degradation is a central regulatory system in GA signaling pathway. Intensive studies have revealed the degradation mechanism of DELLA and the functions of DELLA as a transcriptional regulator. Meanwhile, recent studies suggest the existence of a DELLA-independent GA signaling pathway. In this review, we summarized the DELLA-independent GA signaling pathway together with the well-analyzed DELLA-dependent pathway.
The purpose of the present study was to test whether hyperlipidaemia and insulin resistance in type 2 diabetic Otsuka Long-Evans Tokushima Fatty (OLETF) rats can be improved by dietary supplementation with purified eicosapentaenoic acid (EPA) or oleic acid (OA). Male OLETF rats were fed powdered chow (510 g fat/kg) alone (n 8) or chow supplemented with 1·0 g EPA-(n 8) or OA-(n 8) rich oil/kg per d from 5 weeks until 30 weeks of age. An oral glucose tolerance test and hyperinsulinaemic euglycaemic clamp was performed at 25 and 30 weeks of age. EPA supplementation resulted in significantly ðP,0:05Þ reduced plasma lipids, hepatic triacylglycerols, and abdominal fat deposits, and more efficient in vivo glucose disposal compared with OA supplementation and no supplementation. OA supplementation was associated with significantly increased insulin response to oral glucose compared with EPA supplementation and no supplementation. Inverse correlation was noted between glucose uptake and plasma triacylglycerol levels (r 2 0·86, P,0·001) and abdominal fat volume (r 20·80, P,0·001). The result of oral glucose tolerance test study showed that the rats fed EPA tended to improve glucose intolerance, although this was not statistically significant. Levels of plasma insulin at 60 min after glucose was significantly increased in rats fed OA compared with the other two groups. The results indicate that long-term feeding of EPA might be effective in preventing insulin resistance in diabetes-prone rats, at least in part, due to improving hypertriacylglycerolaemia.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
