Gene expression analysis of efflux and influx (oct1) transporters in different cml phases
The Philadelphia (Ph) chromosome is produced by the reciprocal translocation of chromosomes 9 and 22, which is a hallmark of chronic myeloid leukaemia (CML), a clonal myeloproliferative illness. Organic cation transporter 1 (OCT-1) and organic cation/carnitine transporter 2 (OCTN2) are two membrane transporters that are necessary for the entry of imatinib into cells. Consequently, as their low expression lowers the intracellular imatinib concentration, membrane transporters have also been identified as significant factors to poor treatment response.
