Apoptotic gene expression under influence of fludarabine and cladribine in chronic lymphocytic leukemia-microarray study.
Journal Title: Pharmacological Reports - Year 2012, Vol 64, Issue 2
Abstract
Background: A deep insight into gene expression profiling (GEP) is a key to understanding the background of disease. It can lead to identification of diagnostic and prognostic factors and then to a selection of the most appropriate therapy. The aim of this study was to evaluate differences in apoptotic gene expression in chronic lymphocytic leukemia (CLL) cells influenced by fludarabine (FA) or cladribine (2-CdA). Methods: GEP was performed in cells obtained from 10 untreated CLL patients and cultured in vitro with FA or 2-CdA. Ninety-three selected apoptotic genes were analyzed using 384 TaqMan® Low Density Arrays in pooled RNA. Results: Relevant results were found in a set of 27 genes, however, the most striking differences between FA and 2-CdA were observed in the following 5 genes: BAD, TNFRSF21, DAPK1, CARD 6 and CARD 9. Conclusion: We have found some differences in apoptotic gene expression between FAand 2-CdA. These findings give prominence to genes qualifying for further studies currently conducted in our Department.

Antioxidant treatment normalizes renal Na(+),K(+)-ATPase activity in leptin-treated rats.
Hyperleptinemia may be involved in the pathogenesis of obesity-associated hypertension, however, the mechanism of hypertensive effect of leptin is incompletely elucidated. Previously, we have demonstrated that chronic hy...
Effects of midazolam and buspirone on in vivo concentration of amino acids and monoamine metabolites in the rat hippocampus.
The effects of anxiolytic doses of buspirone and midazolam (established in the conditioned fear test) on extracellular concentrations of glutamate, GABA, serotonin and dopamine metabolites in the hippocampus were examine...
Methamphetamine-induced neurotoxicity: the road to Parkinson's disease.
Studies have implicated methamphetamine exposure as a contributor to the development of Parkinson's disease. There is a significant degree of striatal dopamine depletion produced by methamphetamine, which makes the toxin...
IFN-γ suppresses the high glucose-induced increase in TGF-β1 and CTGF synthesis in mesangial cells.
Mesangial cells are the main source of renal interstitial fibrosis in diabetic nephropathy (DN). Interferon-γ (IFN-γ) is a key cytokine that may play a potential therapeutic role in reducing fibrosis. Here, we focus on t...
Changes in the Egr1 and Arc expression in brain structures of pentylenetetrazole-kindled rats.
Background: Epileptogenesis is regarded as a complicated and relatively poorly understood phenomenon. Some of immediate early genes (IEGs) as egr1 (zif268) or arc (arg3.1) are believed to play an important role in the pr...
