Membrane lipid metabolism is involved in regulating ??aminobutyric acid?mediated cold tolerance in peach fruit

چکیده
The cold-sensitive peach fruits are prone to chilling injury (CI). ?-aminobutyric acid (GABA) has been confirmed effectively improve peaches’ cold tolerance. This research aimed probe the role of dynamic changes in membrane lipid metabolism GABA-mediated tolerance and reveal underlying mechanisms based on metabolomics. GABA treatment improved by reducing phosphatidic (PA) accumulation via inhibiting phospholipid degradation, attenuating PA biosynthesis, maintaining higher phosphatidylcholine (PC) phosphatidylethanolamine (PE) levels. Under conditions, protected peaches against low-temperature stress delayed CI PC PE levels enhancing massive diacylglycerol (DAG) triacylglycerol (TAG). study provides a novel mechanism regulating postharvest fruits.

n-6:n-3 PUFA ratio is involved in regulating lipid metabolism and inflammation in pigs.
The objective of the present study was to investigate the optimal dietary n-6:n-3 PUFA ratios that regulate lipid metabolism and inflammation in pigs. A total of ninety-six cross-bred (Large White × Landrace) growing-finishing pigs (73·8 (SEM 1·6) kg) were chosen and fed one of the four isoenergetic diets with n-6:n-3 PUFA ratios of 1:1, 2·5:1, 5:1 and 10:1. The growth performance of pigs fed t...
متن کاملPutrescine is involved in Arabidopsis freezing tolerance and cold acclimation by regulating abscisic acid levels in response to low temperature.
The levels of endogenous polyamines have been shown to increase in plant cells challenged with low temperature; however, the functions of polyamines in the regulation of cold stress responses are unknown. Here, we show that the accumulation of putrescine under cold stress is essential for proper cold acclimation and survival at freezing temperatures because Arabidopsis (Arabidopsis thaliana) mu...

The aim of this study was to investigate the effect of different concentrations of conjugated linoleic acid (CLA) on in vitro maturation (IVM) and lipid metabolism-related genes in oocytes. In vitro maturation of oocyte was performed in the presence of control (0.0), 50, 100, and 200 µM CLA. Nuclear status and mRNA abundance of selected genes were evaluated following 24 h of IVM. Following the ...
متن کاملMicroRNAs regulating lipid metabolism in atherogenesis.
MicroRNAs have emerged as important post-transcriptional regulators of lipid metabolism, and represent a new class of targets for therapeutic intervention. Recently, microRNA-33a and b (miR-33a/b) were discovered as key regulators of metabolic programs including cholesterol and fatty acid homeostasis. These intronic microRNAs are embedded in the sterol response element binding protein genes, S...
متن کاملDietary Njavara rice bran oil reduces experimentally induced hypercholesterolaemia by regulating genes involved in lipid metabolism.
The present study was carried out to evaluate the anti-atherogenic effect of Njavara rice bran oil (NjRBO) on atherosclerosis by modulating enzymes and genes involved in lipid metabolism in rats fed a high-cholesterol diet (HCD). Adult male rats (Sprague-Dawley strain, weighing 100-120 g) were divided into three groups of nine animals each. Group I served as the control, group II were fed a HCD...
