The relative isoform expression levels of isocitrate dehydrogenase in breast cancer: IDH2 is a potential target in MDA-MB-231 cells [PDF]
Korean Journal of Clinical Oncology, 2023 Purpose The isocitrate dehydrogenase (IDH) family plays an essential role in metabolism and energy production. The relative expression levels of IDH isoforms (IDH1, IDH2, and IDH3) have prognostic significance in several malignancies, including breast ...

A comparison of the phosphorylated and unphosphorylated forms of isocitrate dehydrogenase from Escherichia coli ML308 [PDF]
, 1984 NADP+ can protect active isocitrate dehydrogenase against attack by several proteases. Inactive phosphorylated isocitrate dehydrogenase is much less susceptible to proteolysis than the active enzyme, and it is not protected by NADP+.

A spatial analysis of physiological changes associated with infection of cotyledons of marrow plants with cucumber mosaic virus [PDF]
, 1996 Changes in host primary metabolism associated with the compatible interaction between cucumber mosaic virus and cotyledons of the marrow plant (Cucurbita pepo L.) have been localized, first by measuring activities of key enzymes in infected and ...

Inhibition by alloxan of mitochondrial aconitase and other enzymes associated with the citric acid cycle [PDF]
, 1984 Considerable variations were found in the in vitro effect of alloxan on mouse liver enzymes associated with the citric acid cycle. The following approximative alloxan concentrations induced 50% inhibition of enzyme activity: 10−6 M for aconitase, 10−4 M ...

Minimizing acetate formation in E. coli fermentations [PDF]
, 2007 Escherichia coli remains the best established production organisms in industrial biotechnology. However, during aerobic fermentation runs at high growth rates, considerable amounts of acetate are accumulated as by-product.

Oncometabolites: tailoring our genes [PDF]
, 2015 Increased glucose metabolism in cancer cells is a phenomenon that has been known for over 90 years, allowing maximal cell growth through faster ATP production and redistribution of carbons towards nucleotide, protein and fatty acid synthesis.

Research Progress of Isocitrate Dehydrogenase Gene Mutation Therapy
Xiehe Yixue Zazhi, 2023 Isocitrate dehydrogenase (IDH), a key enzyme in the tricarboxylic acid cycle, plays an important role in cellular energy metabolism. When the IDH gene is mutated, the enzyme activity is altered, resulting in an accumulation of a large amount of the tumor
