"This project is designed to study possible mechanisms of anti-inflammatory effects and to detect side effects of\u00A0sanguinarine, chelerythrine, berberine, protopine, and colchicine,\u00A0all alkaloids displaying anti-inflammatory activity. The project is focused on studying the influence of tested alkaloids on the expression of enzymes whose activity is necessary for the involvement of neutrophilic granulocytes in inflammatory response. As a well-established model for studying phagocyte NADPH oxidase, myeloperoxidase (MPO), and cyclooxygenase 2 (COX-2), human promyelocytic leukemia HL-60 cells induced by dimethyl sulfoxide to\u00A0differentiate into neutrophil-like cells will be used. The aim of the designed experiments is to explore the effect of tested alkaloids on induction of apoptosis, the\u00A0effect on expression of\u00A0selected NADPH oxidase subunits, i.e. membrane subunit gp91phox and cytosolic subunit p67phox, and the effect on expression and activity of MPO and COX-2 during differentiation of HL-60"@en .
