Abstract:
Immunophenotype might be an important indicator for multidrug resistance (MDR) profiles in childhood acute lymphoblastic leukemia (ALL). The authors analyzed the messenger RNA (mRNA) levels of MDR1, multidrug resistance-associated protein (MRP), and lung resistance-related protein (LRP) by reverse transcriptase-polymerase chain reaction (RT-PCR) in childhood pre-B ALL, T-cell ALL, and acute nonlymphoblastic leukemia (ANLL). Results showed that MRP and LRP, but not MDR1, mRNAs are overexpressed, particularly in children with pre-B ALL compared with T-cell ALL and ANLL tested. In addition, the MRP and LRP mRNA expression levels in initial diagnosis and first relapse samples of one patient with pre-B ALL were similar. Consequently, these preliminary results suggest that the expression of these MDR-related genes in childhood ALL might be regulated differently in a lineage dependent manner.
