AREAS OF RESEARCH:
• Intracellular signaling and its role in regulation of responses and adaptation of animal cells to different kinds of stress situations. • The role of regulatory proteins (protein kinases, matrix metalloproteinases) in mechanisms of short-term and long-term adaptation of the heart. • Molecular mechanisms of doxorubicin effects on the heart, modulation of toxic effects of doxorubicin by natural substances. • The role of intracellular signaling in hypertension. • Mitochondrial function in heart during physiological and pathophysiological conditions (ischemia, hypoxia, hypertension, diabetes mellitus). Interaction between intracellular organelles and membrane systems. • Substrate and energy metabolism in the heart. • Involvement of the Na,K-ATPase, a key system involved in maintaining the intracellular sodium ion concentration, in the development of various diseases like hypertension, streptozotocin-induced diabetes, lipid metabolism disorders, inflammation diseases, etc. • Study the effect of various natural substances on functional properties of Na,K-ATPase for eventual protection of enzyme.
