| 内容記述 | The aim of the present study was: (i) to investigate the possibility of sensitizing leukemia lymphocytes to anticancer drugs using docosahexaenoic acid (DHA); (ii) to find combinations with synergistic cytotoxic effect on leukemia lymphocytes, without or with only very low cytotoxicity towards normal lymphocytes; (iii) and to clarify the role of reactive oxygen species (ROS) in the induction of apoptosis and cytotoxicity by such combinations. The study covered 15 anticancer drugs, conventional and new-generation. Well-expressed synergistic cytotoxic effects were observed after treatment of leukemia lymphocytes (Jurkat) with DHA in combination with: barasertib, lonafarnib, everolimus, and palbociclib. We selected two synergistic combinations, DHA with everolimus or barasertib, and investigated their effects on viability of normal lymphocytes, as well as on the production of ROS and induction of apoptosis in both cell lines (leukemia and normal). At the selected concentrations, DHA, everolimus and barasertib (applied separately) were cytotoxic towards leukemia lymphocytes, but not normal lymphocytes. In leukemia cells, the cytotoxicity of combinations was accompanied by strong induction of apoptosis and production of ROS. In normal lymphocytes, drugs alone and in combination with DHA did not affect the level of ROS and did not induce apoptosis. To our knowledge, the present study is the first to report synergistic ROS-dependent cytotoxicity between DHA and new-generation anticancer drugs, such as everolimus and barasertib, that is cancer cell-specific (particularly for acute lymphoblastic leukemia cells Jurkat). These combinations are harmless to normal lymphocytes and do not induce abnormal production of ROS in these cells. The data suggest that DHA could be used as a supplementary component in anticancer chemotherapy, allowing therapeutic doses of everolimus and barasertib to be reduced, minimizing their side-effects. | |||||
