The coordinate regulation of proliferation and differentiation is disturbed in aberrant proliferating tumor cells. Dr. Glass’s laboratory recently described a mechanism in which induction of the Ets repressor METS/PE1 links terminal differentiation to cell cycle arrest. The collaborative project aims at defining a putative role of the METS/DP103 disfunction in tumorigenesis. Due to its important role in terminal differentiation and cell cycle arrest, it is conceivable that disruption of METS/DP103 function could lead to myeloproliferation and could contribute to leukemogenesis. We have started to analyse METS/DP103 expression in normal human and myeloid leukemia cells and search for mutations in METS/DP103 genes that might correlate with loss/gain of function and aberrant proliferation.
