Pre-B cells from normal control, preleukemic, fully leukemic and fully leukemic, nilotinib-treated P190 BCR/ABL transgenic mice


ABSTRACT: Precursor B-lineage acute lymphoblastic leukemia (pre-B ALL) can be subdivided into different categories based on genetic abnormalities. One type of pre-B ALL is characterized by the presence of the Philadelphia (Ph) chromosome, the derivative chromosome 22 that is one product of a reciprocal translocation between chromosomes 22 and 9. The 22/9 translocation fuses the 5’ part of the BCR gene to the 3’ end of the c-ABL gene. The resulting BCR/ABL fusion encodes a Bcr/Abl protein with deregulated Abl kinase activity. Two major fusion proteins are found in Ph-positive leukemias which differ in molecular weight and the size of the Bcr moiety. The P190 Bcr/Abl protein is common in Ph-positive ALL. Targeted tyrosine kinase inhibitors such as nilotinib are used therapeutically to treat this type of leukemia.
