Multi-drug transporter MDR1 gene polymorphism and prognosis in adult acute lymphoblastic leukemia.
Journal Title: Pharmacological Reports - Year 2005, Vol 57, Issue 6
Abstract
P-glycoprotein (P-gp), a membrane transporter encoded by MDR1 gene, influences pharmacokinetics of anti-cancer drugs and contributes to multi-drug resistance phenotype in adult acute lymphoblastic leukemia (ALL). In this study, we explored prognostic and functional role of single nucleotide polymorphism C3435T in MDR1 gene in 44 adult Caucasian patients with ALL. We found that the outcome of chemotherapy as well as MDR1 gene expression, P-gp expression and P-gp activity in isolated ALL blast cells were comparable among the patients carrying different MDR1 genotypes. Our results suggest that C3435T polymorphism in MDR1 gene is not a major prognosticator in adult ALL.

Although neuroprotection is effective only against certain aspects of a complex cascade of pathological events during the development and course of epilepsy, it might be a promising option in the treatment of this diseas...
Analgesic and anticonvulsant activity of new derivatives of 2-substituted 4-hydroxybutanamides in mice.
Earlier in vitro studies of the compounds marked as GT27, GT28, GT29 and BM128 revealed their inhibitory action towards murine γ-aminobutyric acid (GABA) transporters (mGAT1-mGAT4). In the present paper, the pharmacologi...
Behavioral effects of Bcl-2 deficiency: implications for affective disorders.
New hypotheses regarding affective disorders suggest a critical role for cellular resilience and plasticity. Bcl-2 is a central protein in these processes and is elevated by mood stabilizers and antidepressants. In previ...
Neuropeptide FF receptor modulates potassium currents in a dorsal root ganglion cell line.
This study investigated the presence of neuropeptide FF (NPFF) receptors on F-11 cells, a hybridoma derived from rat dorsal root ganglia (DRG) and mouse neuroblastoma. Binding experiments revealed a low density (4 fmol/m...
