Title Targeting isocitrate dehydrogenase (IDH) in cancer.
URL
Abstract Text Isocitrate dehydrogenase (IDH) is an essential enzyme for cellular respiration in the tricarboxylic acid (TCA) cycle. Recurrent mutations in IDH1 or IDH2 are prevalent in several cancers including glioma, acute myeloid leukemia (AML), cholangiocarcinoma and chondrosarcoma. The mutated IDH1 and IDH2 proteins have a gain-of-function, neomorphic activity, catalyzing the reduction of α-ketoglutarate (α-KG) to 2-hydroxyglutarate (2-HG) by NADPH. Cancer-associated IDH mutations block normal cellular differentiation and promote tumorigenesis via the abnormal production of the oncometabolite 2-HG. High levels of 2-HG have been shown to inhibit α-KG dependent dioxygenases, including histone and deoxyribonucleic acid (DNA) demethylases, which play a key role in regulating the epigenetic state of cells. Current targeted inhibitors of IDH1 (AG120, IDH305), IDH2 (AG221), and pan-IDH1/2 (AG881) selectively inhibit mutant IDH protein and induce cell differentiation in in vitro and in vivo models. Preliminary results from phase I clinical trials with IDH inhibitors in patients with advanced hematologic malignancies have demonstrated an objective response rate ranging from 31% to 40% with durable responses (>1 year) observed. Furthermore, the IDH inhibitors have demonstrated early signals of activity in solid tumors with IDH mutations, including cholangiocarcinomas and low grade gliomas.

Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
  • Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

  • Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.
