The level of MEF but not ELF-1 correlates with FAB subtype of acute myeloid leukemia and is low in good prognosis cases

Leuk Res. 2003 May;27(5):387-92. doi: 10.1016/s0145-2126(02)00214-x.

Abstract

ETS proteins (such as PU.1, Fli-1 and ETS-1) have been shown to play important roles in normal and abnormal hematopoiesis. We examined the expression of the ELF subfamily of ETS genes (ELF-1, MEF and NERF) in acute myeloid leukemia (AML) cells using Northern blot analysis. ELF-1 and MEF were expressed in all samples, whereas NERF was not. The relative expression (RE) of MEF, but not ELF-1, was significantly lower (P<0.0001) in AML with t(8;21) and t(15;17) compared with AML with normal karyotype. The pattern of MEF expression was not uniform among cells with CD34(+)/CD33(+). It is suggested that the low RE of MEF might be part of a gene expression profile characterizing AML with a good prognosis.
