SKI and neoplasm: Interestingly, we also found aberrantly high SKI expression levels in tumor cells of some erythroleukemia patients, and that in vivo overexpression of a SKI ORF in BM-derived HSPC resulted in an erythroleukemia-like disease in mice, suggesting that SKI expression may not only be critical for impaired erythroid differentiation in Nsd1−/− mice but also a driver of the human disease62.
