text_1: A gene that warrants further studies is the erythropoietin receptor that is 7.4-fold higher expressed in TEL-AML1-positive cases compared to other precursor B-ALL cases confirming other gene expression classification studies.
text_2: Another recent gene expression study of large numbers of cases provided support for the hypothesis that distinct leukemias are specified by each of the unique chromosomal abnormalities found in lymphoblastic leukemias.
