BACKGROUND The accumulation of mutagenic substances in the human body may result in DNA metabolism disruption followed by carcinogenesis. As a consequence of mutations in the genes coding for transmembrane protein pumps, the intracellular concentration of xenobiotics may significantly increase. This, in turn, may provoke altered risk for cancer development.(More)
Lentiviral vectors are efficient vehicles for stable gene transfer in both dividing and non-dividing cells. This feature among others makes lentiviral vectors a powerful tool in molecular research. However, the use of lentiviruses in research studies and clinical trials requires a precise and validated titration method. In this study, we describe a(More)
INTRODUCTION The dopaminergic system plays a crucial role in the development of alcohol dependence. Regulation of the extracellular dopamine concentration is driven by dopamine transporter. Both, the expression and function of dopamine transporter, are influenced by chronic alcohol intake. Dopamine transporter (DAT) gene is also supposed to be(More)
The influence of an antiestrogen, indole-3-carbinol (I3C) on the expression of CYP1A1, CYP1B1 and AhR genes was investigated in an attempt to establish whether I3C could increase the expression of genes involved in estrone metabolism. Another purpose was to examine the proliferation of an estrogen-dependent breast cancer cell (MCF-7 line) under the(More)
Multidrug resistance (MDR) in leukemia patients is a great incentive to the development of new drugs. In a search for potential multidrug resistance modulators we tested a group of oleanolic acid (OA) analogues modified at C-3, C-11, C-12 and C-28 using an experimental model consisting of three human acute lymphoblastic leukemia cell lines (CCRF-CEM and(More)
Contribution of the protein kinase A (PKA) and protein kinase C (PKC) signalling pathways to the regulation of 11beta-hydroxysteroid dehydrogenase type II (HSD11B2) gene expression was investigated in human breast cancer cell line MCF-7. Treatment of the cells with an adenylyl cyclase activator, forskolin, known to stimulate the PKA pathway, resulted in an(More)
