We have investigated the effects of PES1 and UBF1 on the growth and differentiation of cell lines derived from 32D cells, an interleukin-3 (IL-3)-dependent murine myeloid cell line. Parental 32D cells and 32D IGF-IR cells (expressing increased levels of the type 1 insulin-like growth factor I [IGF-I] receptor [IGF-IR]) do not express insulin receptor substrate 1 (IRS-1) or IRS-2. 32D IGF-IR cells differentiate when the cells are shifted from IL-3 to IGF-I. Ectopic expression of IRS-1 inhibits differentiation and transforms 32D IGF-IR cells into a tumor-forming cell line. We found that PES1 and UBF1 increased cell size and/or altered the cell cycle distribution of 32D-derived cells but failed to make them IL-3 independent. PES1 and UBF1 also failed to inhibit the differentiation program initiated by the activation of the IGF-IR, which is blocked by IRS-1. 32D IGF-IR cells expressing PES1 or UBF1 differentiate into granulocytes like their parental cells. In contrast, PES1 and UBF1 can transform mouse embryo fibroblasts that have high levels of endogenous IRS-1 and are not prone to differentiation. Our results provide a model for one of the theories of myeloid leukemia, in which both a stimulus of proliferation and a block of differentiation are required for leukemia development.

The chromosome inversion inv(16)(p13;q22), found in 8% of acute myeloid leukemia (AML) cases, fuses the CBFB and MYH11 genes to produce the leukemic oncoprotein CBFβ-SMMHC. This fusion protein has higher affinity and altered stoichiometry for RUNX1 relative to the native CBFβ (Cao et al., 1997; Lukasik et al., 2002). During development, CBFβ-SMMHC expression blocks definitive hematopoiesis and embryos die at mid-gestation (Castilla et al., 1996), a similar phenotype to that of Runx1- and Cbfb-knock out embryos (Wang et al., 1996a; Wang et al., 1996b), indicating that CBFβ-SMMHC has a dominant negative effect on RUNX function.
