MetabolomicsIDH1 Mutations Induce Organelle Defects Via Dysregulated Phospholipids (CSHNeg)

Infiltrating gliomas are devastating and incurable tumors. Amongst all gliomas, those harboring an isocitrate dehydrogenase 1 mutation (IDHmut), acquire a different tumor biology and clinical manifestation than those that are IDHWT. Understanding the unique metabolic profile reprogrammed by IDH1 ...

TranscriptomicsPatient glioma microarray for Impaired histone demethylation contributes to the cell differentiation arrest induced by cancer-associated isocitrate dehydrogenase mutation
To study the effects of IDH mutations, we collected and performed gene expression microarray analysis with tumor specimens from patients with grade II-III oligodendroglioma. Sequencing for mutations of IDH1 and IDH2 was done. Gene expression was compared between IDH wildtype vs. mutant samples

GenomicsInduction of sarcomas by mutant IDH2
More than 50% of patients with chondrosarcomas exhibit gain-of-function mutations in either isocitrate dehydrogenase 1 (IDH1) or IDH2. In this study, we performed genome-wide CpG methylation sequencing of chondrosarcoma biopsies and found that IDH mutations were associated with DNA hypermethylation ...

GenomicsWhole exome sequencing analyses of human, IDH2-mutated, acute myeloid leukemia samples from patients before or during treatment with Enasidenib.
Mutations in isocitrate dehydrogenase 2 (IDH2) occur in many cancers including Acute Myeloid Leukemia (AML). In preclinical models mutant IDH2 causes partial hemopoietic differentiation arrest. Recently, we showed that single agent Enasidenib, a first-in-class, selective mutant IDH2 inhibitor, produ...

TranscriptomicsIsocitrate dehydrogenase 1 mutations prime the all-trans-retinoic acid myeloid differentiation pathway in acute myeloid leukemia HL-60 cells
Human acute myeloid leukemia HL60 cells were transduced with IDH1-WT or IDH1-R132H, and corresponding sub-clones were generated by FACS. In a first series of experiments, cells expressing wt and mutant IDH1were treated with either 1µM all-trans retinoic acid (ATRA) or with vehicle (DMSO) for 24 hrs...

TranscriptomicsMutations in IDH1 and IDH2 are associated with DNA hypermethylation in intrahepatic cholangiocarcinomas
We compared the DNA methylation profiles of 12 intrahepatic cholangiocarcinomas harboring mutations in the genes encoding isocitrate dehydrogenase, IDH1 and IDH2, with 28 intrahepatic cholangiocarcinomas without these mutations. We profiled these samples with the Illumina HumanMethylation450 BeadChi...

TranscriptomicsOncogenic SDH mutation underlies global epigenomic instability in gastrointestinal stromal tumor
We have discovered a striking connection between mitochondrial dysfunction and epigenomic instability, manifested by global biallelic DNA cytosine 5-methylation and loss of 5-hydroxymethycytosine within succinate dehydrogenase (SDH)-null gastrointestinal stromal tumors (GIST) relative to those beari...
