| Popis | The monitoring of hOCT1 mRNA expression in patients with chronic myelogenous leukemia (CML) was used for predicting the response to imatinib treatment. However, different cell populations from patients who received various degrees of pretreatment were used for this analysis. Therefore, several biases in the results and their interpretation may arise. We investigated hOCT1 mRNA expression in different cell populations of peripheral blood (PB) from healthy volunteers and in imatinib nave de novo CML patients by analyzing changes in hOCT1 mRNA expression during the first 6 months of imatinib therapy. The hOCT1 mRNA expression was significantly higher in PB polymorphonuclears compared to mononuclears. The hOCT1 mRNA expression in total PB leukocytes is, therefore, preferentially determined by the percentage of polymorphonuclears. Expression in each analyzed group of cells was always significantly lower in imatinib nave de novo CML patients compared to healthy volunteers. This difference disappeared after the initiation of imatinib therapy, suggesting that CML tumor burden and the degree of pretreatment at the time of monitoring were both influencing factors. |
