Abstract Text Purpose: Somatic mutations in IDH1/2 occur in approximately 20% of patients with myeloid neoplasms, including acute myeloid leukemia (AML). IDH1/2MUT enzymes produce D-2-hydroxyglutarate (D2HG), which associates with increased DNA damage and improved responses to chemo/radiotherapy and PARP inhibitors in solid tumor cells. Whether this also holds true for IDH1/2MUT AML is not known.Experimental Design: Well-characterized primary IDH1MUT, IDH2MUT, and IDH1/2WT AML cells were analyzed for DNA damage and responses to daunorubicin, ionizing radiation, and PARP inhibitors.Results:IDH1/2MUT caused increased DNA damage and sensitization to daunorubicin, irradiation, and the PARP inhibitors olaparib and talazoparib in AML cells. IDH1/2MUT inhibitors protected against these treatments. Combined treatment with a PARP inhibitor and daunorubicin had an additive effect on the killing of IDH1/2MUT AML cells. We provide evidence that the therapy sensitivity of IDH1/2MUT cells was caused by D2HG-mediated downregulation of expression of the DNA damage response gene ATM and not by altered redox responses due to metabolic alterations in IDH1/2MUT cells.Conclusions:IDH1/2MUT AML cells are sensitive to PARP inhibitors as monotherapy but especially when combined with a DNA-damaging agent, such as daunorubicin, whereas concomitant administration of IDH1/2MUT inhibitors during cytotoxic therapy decrease the efficacy of both agents in IDH1/2MUT AML. These results advocate in favor of clinical trials of PARP inhibitors either or not in combination with daunorubicin in IDH1/2MUT AML. Clin Cancer Res; 24(7); 1705-15. ©2018 AACR.

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.
