CML is cytogenetically marked by the philadelphia chromosome, which originates from a reciprocal translocation between chromosome 9 and 22 and is molecularly marked a chimeric bcr-abl gene, resulting from juxta-positive of the abl proto-oncogene on chromosome 9 with the bcr gene, which is normally located on chromosome 22. The chimeric bcr-abl gene expression an 8. 5kb hybrid mRNA transcript giving rise to a 210-KD fusion protein (P210〓) with increased tyrosine kinase activity. P210〓 plays a key role in the pathogenesis of CML. The continuous cell line K562 was established from the pleural effusion of a 53-year-old female with CML in terminal blast crisis, and was a human erythroleukemia line, contained Ph chromosome.
