Noninvasive measurements of [1-(13)C]glycogen concentrations and metabolism in rat brain in vivo.
Using a specific 13C NMR localization method, 13C label incorporation into the glycogen C1 resonance was measured while infusing [1-(13)C]glucose in intact rats. The maximal concentration of [1-(13)C]glycogen was 5.1 +/- 0.6 micromol g(-1) (mean +/- SE, n = 8). During the first 60 min of acute hyperglycemia, the rate of 13C label incorporation (synthase flux) was 2.3 +/- 0.7 micromol g(-1) h(-1...
متن کاملBiosynthesis of zearalenone: a simple and efficient method to incorporate [13C]acetate label by using solid cultures.
A suitable method was developed to efficiently incorporate 13C-labeled acetate into zearalenone by using solid cultures. Periodic feeding of the label during the zearalenone production phase significantly increased the label incorporation for the singly labeled acetate.
متن کاملCarbon Allocation in Rhodococcus jostii RHA1 in Response to Disruption and Overexpression of nlpR Regulatory Gene, Based on 13C-labeling Analysis
Nitrogen lipid regulator (NlpR) is a pleiotropic regulator that positively controls genes associated with both nitrogen and lipid metabolism in the oleaginous bacterium Rhodococcus jostii RHA1. In this study, we investigated the effect of nlpR disruption and overexpression on the assimilation of 13C-labeled glucose as carbon source, during cultivation of cells under nitrogen-limiting and nitrog...
متن کاملFurther Studies on the Biosynthesis of Pseudoisoeugenols in Tissue Cultures of Pimpinella anisum
Tissue cultures o f Pimpinella anisum and P. major were used to study the biosynthesis o f pseudoisoeugenols. The putative precursors were labelled with 13C with one exception that was labelled with i4C. The incorporation o f the label was controlled by 13C N M R and liquid scintil lation, respectively. The biosynthetic sequence found was L-phenylalanine, /-cinnamic acid, /?-coumaric acid, / 7...
متن کاملTracer‐Based Metabolic NMR‐Based Flux Analysis in a Leukaemia Cell Line
High levels of reactive oxygen species (ROS) have a profound impact on acute myeloid leukaemia cells and can be used to specifically target these cells with novel therapies. We have previously shown how the combination of two redeployed drugs, the contraceptive steroid medroxyprogesterone and the lipid-regulating drug bezafibrate exert anti-leukaemic effects by producing ROS. Here we report a 1...
