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.

Expression of multiple Transient Receptor Potential channel genes in murine 3T3-L1 cell lines and adipose tissue.
Background: Calcium and its signaling have a role in adipogenesis. Transient Receptor Potential (TRP) channels are non-selective cation channels with a high permeability to calcium. Methods: In the present study the expr...
Effect of N-methyl-D-aspartate (NMDA) receptor antagonists on alpha-synuclein-evoked neuronal nitric oxide synthase activation in the rat brain.
alpha-Synuclein (ASN), a small presynaptic protein that is abundant in the brain, is implicated in the pathogenesis of neurodegenerative disorders including Parkinson's and Alzheimer's disease. The central domain of alph...
