DNA methylation changes induced by overexpression of IDH1mut or treatment with 2HG in the sorted mouse bone marrow cells

ABSTRACT: 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. HoxA9 immortalised bone marrow cells from C57BJ/6 mice were tranduced with either empty vector or pSF91-IDH1wt-IRES-EGFP, or pSF91-IDH1mut-IRES-GFP and transplanted in irradiated recipient mice. Alternatively, HoxA9 immortalised cells transduced with empty vector transplanted mice were treated with R-2HG at dose of 1mg/day for four weeks. Four weeks after transplantation/treatment GFP+ cells were sorted from mouse bone marrow, from which total DNA was extracted and subjected to Reduced Representation Bisulfite Sequencing (RRBS) to determine the genome-wide methylation signature.
