Improving Cold Atmospheric Pressure Plasma Efficacy on Breast Cancer Cells Control-Ability and Mortality Using Vitamin C and Static Magnetic Field

In the last decades, there have been numerous reports about the separate interactions of a magnetic field and cold atmospheric plasma (CAP) with the biological systems. We have investigated the combined effect of CAP with the static magnetic field (SMF) as an effective method for cancer cells treatment. MDA-MB-231 breast cancer cells were cultured and treated with CAP with different input power and exposure times in the presence and absence of the SMF. Vitamin C was also used in medium, and cell viability was investigated in the presence and absence of this antioxidant compound. The MTT assay was employed to measure cell survival, and a T-test or one-way ANOVA was used to assess the significance level of quantitative data. In order to determine the migration rate of cancer cells, wound healing assay was carried out. Results show that the presence of the SMF and vitamin C as well as increasing the input power significantly decrease the survival and migration rate of the cells. The results of the present investigation will greatly contribute to improve the CAP efficiency in cancer therapy by using the SMF and vitamin C as a complement to conventional CAP therapies.
