Overexpression of cSki in hematopoietic stem and progenitor cells

ABSTRACT: Human cSki was overexpressed using MIGR1 retrovirus in sorted murine Lin-c-Kit+Sca-1+ cells. Cells were infected and cultured for 2 days after infection prior to isolation of GFP+ve cells and microarray. GFP+ve MIGR1 and cSKI cells were compared. Each sample represents an independent infection with either cSki or MIGR1 Comparison of GFP+ve LKS+ infected with MIGR1 and cSki

The proto-oncogene SKI is highly expressed in human myeloid leukemia and also in murine hematopoietic stem cells. However, its operative relevance in these cells remains elusive. We have over-expressed SKI to define its intrinsic role in hematopoiesis and myeloid neoplasms, which resulted in a robust competitive advantage upon transplantation, a complete dominance of the stem and progenitor compartments, and a marked enhancement of myeloid differentiation at the expense of other lineages.
