The relationship between expression of genes encoding key antioxidant enzymes, heme oxygenase-1, Bcl-2, and Bcl-xl and change in production of reactive oxygen species (ROS) resulting from development of resistance of cancer cells K562, MCF-7, and SKOV-3 to the prooxidant chemotherapeutic agent doxorubicin (DOX) has been studied. Significant increase in mRNA(More)
Expression of genes for redox-dependent glutathione S-transferase isoforms GSTP1-1 and GSTA4-4 in tumor cells K562, MCF-7, and SKOV-3 was studied during the development of resistance to doxorubicin. It was found that the development of resistance was accompanied by predominant increase in the expression of hGSTP1 gene in MCF-7 cells, and hGSTA4 gene in(More)
The expression of genes for thioredoxin isoforms Trx1 and Trx2 was studied in sensitive SKOV-3 and resistant SKVLB human ovarian carcinoma cells. The development of doxorubicin resistance was accompanied by a significant increase in the expression of TRX1 gene and less pronounced increase in TRX2 gene expression.
Factor XIIIa plays an important role in stabilization of formed fibrin clot during blood coagulation. Recent studies proved that factor XIIIa affects formation of coated platelets, which are highly procoagulant and characterized by a high level of alpha-granular proteins on their surface and expose surface phosphatidylserine after platelet activation. The(More)
Platelets, specialized blood cells, are the most important members of the hemostatic system. Upon activation they divide into two subpopulations, differing greatly in their properties. Platelets from one of these subpopulations express phosphatidylserine (PS) on the outer layer of their membrane and retain secreted alpha-granule proteins on their surface.(More)
