Hmga2 Functions As an Oncogene upon the Deletion of Tet2 and Promotes the Pathogenesis of Myelodysplastic Syndrome

High Mobility Group AT-hook 2 (HMGA2) is a chromatin modifier and its overexpression has been found in a subset of patients with myelodysplastic syndrome (MDS). The high level of HMGA2 expression appears to predict poor prognosis in various tumors; however, it remains unclear how HMGA2 dysregulates expression of target genes to facilitate the transformation. To elucidate the mechanisms by which the overexpression of Hmga2 promotes the...
