Gene expression changes induced by overexpression of IDH1mut in the sorted mouse bone marrow cells

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 immortalized bone marrow cells from C57BJ/6 mice were transduced with either empty vector or pSF91-IDH1wt-IRES-EGFP, or pSF91-IDH1mut-IRES-GFP and transplanted in irradiated recipient mice. Four weeks after transplantation, GFP+ cells were sorted from mouse bone marrow, from which total RNA was extracted and subjected to microarray analysis.
