一般描述

Isocitrate dehydrogenase 1 (IDH1) gene is located on human chromosome 2q33. IDH1 is present in the cytoplasm and peroxisomes.[1] It is expressed at high levels in the mammalian liver. IDH1 consists of a C-terminal tripeptide peroxisome, that targets the signal one sequence.[2]

生化/生理作用

Isocitrate dehydrogenase 1 (IDH1) help in the oxidative carboxylation of isocitrate to α-ketoglutarate, that results in the formation of reduced nicotinamide adenine dinucleotide phosphate (NADPH).[1] It participates in lipid metabolism and glucose sensing. Suppressing IDH1 in pancreatic islets affects the insulin secretion, induced by glucose and leads to increase in lactate production.[2]

单位定义

One unit corresponds to the amount of enzyme which converts 1.0 μmol DL-isocitrate to α-ketoglutarate per minute at pH 7.4 and 37 °C (NADP as cofactor).

外形

Supplied as a lyophilized powder containing Tris-HCl pH 8.0, trehalose, ammonium sulfate and DTT

Mutations in the metabolic enzymes isocitrate dehydrogenase 1 (IDH1) and 2 (IDH2) are frequently found in glioma, acute myeloid leukemia (AML), melanoma, thyroid cancer, and chondrosarcoma patients. Mutant IDH produces 2-hydroxyglutarate (2HG), which induces histone- and DNA-hypermethylation through inhibition of

The prognosis of glioblastoma, the most malignant type of glioma, is still poor, with only a minority of patients showing long-term survival of more than three years after diagnosis. To elucidate the molecular aberrations in glioblastomas of long-term survivors, we

Isocitrate dehydrogenase (IDH) enzymes have recently become a focal point for research aimed at understanding the biology of glioma. IDH1 and IDH2 are mutated in 50%-80% of astrocytomas, oligodendrogliomas, oligoastrocytomas, and secondary glioblastomas but are seldom mutated in primary glioblastomas.
