C3435T polymorphism of the MDR1 gene is not associated with P-glycoprotein function of leukemic blasts and clinical outcome in patients with acute myeloid leukemia.
Data from 30 pharmacogenomic studies that investigated MDR1 mRNA expression or gene variants (C3435T, G2677TA, C1236T) and response to therapy in acute myeloid leukaemia (AML) were synthesized.
The present study included 290 acute leukemia cases, comprising of 147 acute lymphocytic leukemia (ALL), 143 acute myeloid leukemia and 249 age-sex matched control samples for the analysis of MDR1 C3435T polymorphism, by the PCR-RFLP method.
The aim of this study was to investigate the potential involvement of the ABCB1 gene exon 26 3435C>T single nucleotide polymorphism (SNP) in the genetic susceptibility to AML and regulation of P-gp expression and activity in AML cells.
