BACKGROUND Sudden cardiac death often involves arrhythmias triggered by metabolic stress. Loss of mitochondrial function is thought to contribute to the arrhythmogenic substrate, but how mitochondria contribute to uncoordinated electrical activity is poorly understood. It has been proposed that the formation of metabolic current sinks, caused by the nonuniform collapse of mitochondrial inner me...
The manipulation of sink to source relations has been subject to extensive plant breeding programs aiming to improve harvest index and thereby crop yield. The introduction of molecular and biochemical tools has enabled scientists to investigate the underlying principles. This has opened up the fascinating possibility of identifying molecular determinants of sink strength and to further increase...
purpose a metabolic abnormality such as obesity is a major obstacle in the maintenance of the human health system and causes various chronic diseases including type 2 diabetes, hypertension, cardiovascular diseases, as well as various cancers. this study was designed to summarize the recent scientific knowledge regarding the anti-obesity role of curcumin (diferuloylmethane), which is isolated f...
Salinization of water and soil has a negative impact on tomato (Solanum lycopersicum L.) productivity by reducing growth of sink organs and by inducing senescence in source leaves. It has been hypothesized that yield stability implies the maintenance or increase of sink activity in the reproductive structures, thus contributing to the transport of assimilates from the source leaves through chan...
Phenylketonuria (PKU) is a metabolic disease causing increased levels of phenylalanine in blood and body fluids. Circulating phenylalanine is normally cleared by phenylalanine hydroxylase (PAH) expressed in the liver. The aim of this study is to exploit the skin as a 'metabolic sink' removing phenylalanine from the blood. We have previously showed that the overexpression of PAH and GTP cyclohyd...
Gibberellins (GAs) are plant growth regulators that are known to stimulate physiological responses in plants and alter the source–sink metabolism through their effect on photosynthesis and sink formation. GAs promote fructose-1,6-biphosphatase and sucrose phosphate synthase and stimulate phloem loading. Photosynthate translocation from source to the developing sink is a major contributing facto...
During grain filling in barley (Hordeum vulgare L. cv. Barke) reserves are remobilized from vegetative organs. Glumes represent the vegetative tissues closest to grains, senesce late, and are involved in the conversion of assimilates. To analyse glume development and metabolism related to grain filling, parallel transcript and metabolite profiling in glumes and endosperm were performed, showing...
