AML1-ETO (+) M2 patients expressed the highest levels (all P<0.01), followed by acute promyelocytic leukemia patients with S type PML-RAR alpha fusion gene.     ///    "abl was selected as control gene, PRAME and AML1-ETO mRNA levels were expressed by their copies/abl copies in percentage. "    ///    "PRAME and AML1-ETO mRNA levels of follow up patients displayed similar kinetic patterns, and correlated well in 43 follow up samples (r=0.88, P<0.01). "    ///    Samples from 7 AML1-ETO (+) M2 patients were detected for AML1-ETO mRNA simultaneously.
