(Submitter supplied) Neomorphic mutations in isocitrate dehydrogenase 1 (IDH1) are driver mutations in acute myeloid leukemia (AML) and other cancers. We report the development of new allosteric inhibitors of mutant IDH1. Crystallographic and biochemical results demonstrated that compounds of this chemical series bind to an allosteric site and lock the enzyme in a catalytically inactive conformation, thereby enabling inhibition of different clinically relevant IDH1 mutants. more...

(Submitter supplied) Mutations in the enzymes IDH1 and IDH2 have been identified in a wide variety of tumors like glioma, chondrosarcoma, thyroid cancer, lymphoma, melanoma, and in acute myeloid leukemia. Mutated IDH1/2 produces the metabolite 2-hydroxyglutarate (2HG), which interferes with epigenetic regulation of gene expression, and thus may promote tumorigenesis.

(Submitter supplied) Allosteric inhibitors of mutant IDH1 or IDH2 induce terminal differentiation in mutant leukemic blasts and may provide durable clinical responses in approximately 40% of acute myeloid leukemia (AML) patients with the mutations. However, most responders eventually relapse. To understand the molecular underpinnings of clinical resistance, we performed multipronged genomic analyses (DNA sequencing, RNA sequencing and cytosine methylation profiling) in longitudinally collected specimens from 68 IDH1/IDH2-mutant AML patients treated with IDH inhibitors (IDHi), and described the evolution of AML genome and epigenome during the therapy and its association with clinical response and relapse. more...

(Submitter supplied) Acute myeloid leukemia (AML) tumors are comprised of multiple cell types with distinct capabilities to propagate the disease and resist therapy. Approximately 20% of AML patients carry gain-of-function mutations in isocitrate dehydrogenase (IDH) 1 or -2 that result in over-production of the onco-metabolite D-2-hydroxyglutarate (2-HG). Small molecule inhibitors that block 2-HG synthesis can induce complete morphological remission even in heavily pre-treated AML patients. more...

(Submitter supplied) Since characterization of molecular alterations in elderly acute myeloid leukemia (AML) patients using comprehensive studies are lacking, we investigated genetic and epigenetic alterations to unravel the specific background of this unfavorable disease. We studied AML patients by sequencing 555 genes on an Illumina HiSeq2000 platform and investigated DNA methylation profiles using the Illumina 450K array.

(Submitter supplied) Mutations in the IDH1 and IDH2 genes encoding isocitrate dehydrogenases are frequent in human glioblastomas1 and cytogenetically normal acute myeloid leukemias (AML)2. These alterations are gain-of-function mutations in that they drive the synthesis of the “oncometabolite” R-2-hydroxyglutarate (2HG)3. It remains unclear how IDH1 and IDH2 mutations modify myeloid cell development and promote leukemogenesis. more...

(Submitter supplied) Microarrays were used to examine gene expression changes between bone marrow isolated haematopoeietic cell populations (LSK cells: Lin-Sca1+cKit+) populations of control and mutant (LysM-KI) mice. The LysM-KI mouse is a murine model which expresses an Idh1 (isocitrate dehydrogenase 1) mutation (Idh1-R132H) in cells of the myeloid lineage. Mutations in IDH1 (and IDH2) in humans are commonly found in cytogenetically normal acute myeloid leukemia as well as glioblastomas. more...

(Submitter supplied) To investigate the mechanisms by which SYK inhibition sensitizes OCI-mIDH1/N cells to ivosidenib, we performed RNA sequencing (RNA-seq) analysis of cells treated with DMSO (vehicle control), ivosidenib alone, fostamatinib alone, entospletinib alone, or the combination of ivosidenib with each of the two SYK inhibitors for 9 days.

(Submitter supplied) To study the mechanism of resistance to ivosidenib, we developed a model of acquired drug resistance by treating ivosidenib-sensitive OCI-mIDH1/N cells continuously with ivosidenib in culture for a period of 2 months followed by a drug washout period. The resulting cell population (OCI-mIDH1/N-R cells) failed to differentiate upon ivosidenib treatment. We then performed RNA sequencing (RNA-seq) analysis of OCI-mIDH1/N and OCI-mIDH1/N-R cells.
