Title: MECOM (Ecotropic Viral Integration Site 1 (EVI1) and Myelodysplastic Syndrome 1 (MDS1-EVI1)
Author:Wieser, Rotraud
Abstract:The MECOM locus in chromosome band 3q26.2 gives rise to two major mRNA and protein species, EVI1 and MDS1/EVI1, of which the former has been characterized far more extensively. EVI1 has been implicated in the maintenance and expansion of normal hematopoietic stem cells. In addition, it plays a role as an oncogene in myeloid leukemia and in certain solid tumors, its overexpression being associated with a dismal prognosis in several of these malignancies. EVI1 exerts its biological effects mainly by regulating gene transcription, and does so by acting as a sequence specific transcription factor, by modulating the activity of other sequence specific transcription factors, and by regulating promoter CpG island methylation.
