Long-term cultivation of cell lines inevitably leads to genetic and epigenetic changes. The aim of this work was a comparative analysis of karyotype and level of the expression of reparative enzyme O6-methylguanine-DNA- ...

The loop domain organization of chromatin, which plays an important role in transcription regulation, may depend on the cell functional state. Aim. To investigate DNA loop reorganization upon functional transitions in the ...

The β-catenin role in myocardium remodeling and hypertrophy development is the subject of numerous and controversial investigations. Aim. To investigate the significance of cardiac ablation of β-catenin for heart development ...

Aim. To investigate an effect of biologically active compounds IFN-α2b, EMAPII, Card medium, fibronectin on the amount of MGMT (O6-methylguanine-DNA methyltransferase) and MARP (anti-Methyltransferase Antibody ...

Aim: To study the effects of total phytohemagglutinin (PHA) and its isolectins on cell death and apoptosis in human HEp-2 carcinoma cells and to analyze the possible molecular mechanisms of lectin induced apoptosis. Materials ...

High intra- and interindividual variations in the expression levels of the human O6-methylguanine-DNA methyltransferase (MGMT) gene have been observed. This DNA repair enzyme can be a cause of resistance of cancer cells ...

The representations of the mutations and the nature of spontaneous mutation process and mutagenesis induced by exogenous oncoviruses, DNAs and proteins-mitogens are analysed. Exogenous biological factors induce DNA damages ...
