Current studies were aimed to elucidate influence of pulsed electromagnetic field stimulation on cell viability and apoptosis induction pathways. For the experimental model we have chosen monocytic cell line MonoMac6 and several apoptosis inducers with different mechanism of death induction like puromycin, colchicine, cyclophosphamide, minocycline and hydrogen peroxide. MonoMac6 cell line was grown at density 1x10(5) cells/well in 96-well culture plates. To induce cell death cell cultures were treated with different apoptosis inducers like puromycin, colchicine, cyclophosphamide, minocycline, hydrogen peroxide and at the same time with pulsed electromagnetic field 50 Hz, 45±5 mT (PEMF) for 4 hour per each stimulation, three times, in 24 hours intervals. Afterwards, cells were harvested for flow cytometry analysis of cell viability measured by annexin V-APC labeled and propidium iodide staining. Expression of apoptosis related genes was evaluated by semi quantitative reverse transcription (RT)-PCR assay. NuPAGE Novex Western blot analysis was carried out for apoptosis inducing factor (AIF) abundance in cytosolic and nuclear extracts of MonoMac6 cells. Puromycin, colchicine and minocycline activated cells and simultaneously treated with PEMF have shown out diminished percentage of annexinV positive (AnV+) cells comparing to controls without PEMF stimulation. MonaMac6 cells puromycin/colchicyne and PEMF treated were to a higher extent double stained (AnV+,PI+), which means increased late apoptotic as well as necrotic (PI+) cells, than non-stimulated controls. On the other hand, minocycline activated cells prior to PEMF treatment showed diminished amount of apoptotic and necrotic (annexin V, annexin V and propidium iodide, propidium iodide positive staining) cells. The opposite effect of PEMF on the percentage of annexin V positively stained cells has been achieved after treatment of MonoMac6 culture with cyclophoshamide and hydrogen peroxide. PEMF enhanced early phase of apoptosis induced by both apoptosis inducing agents. The analysis of expression of the apoptosis related genes in MonoMac6 cultures treated with puromycin and exposed to PEMF performed in reverse transcription of polymerase chain reaction (PCR) assay has shown changes in mRNA of genes engaged in intrinsic apoptotic pathway and pathway with AIF abundance. The most influenced was expression of gene belonging to pro-apoptotic family of Bcl-2 and AIF agent. Examination of immunoblots developed with anti-AIF antibody showed that cytosol content of AIF protein was diminished after puromycin and PEMF treatment of MonoMac6 cells. The obtained results indicate that PEMF affects induction of apoptosis in MonoMac6 cells stimulated to death with inducing agents to a different extent. Main finding of the current results is that, PEMF stimulation of MonoMac6 cells simultaneously treated with puromycin caused changes in the Bcl-family genes expression as well as in caspase independent pathway of apoptosis inducing factor (AIF).
