Abstract

Due to their properties, numerous polyphenols and a static magnetic field could have therapeutic potential. Therefore, the aim of our research was to investigate the effect of caffeic acid (CA), a moderate-strength static magnetic field (SMF) and their simultaneous action on human fibroblasts in order to determine the molecular pathways they affect, which might contribute to their potential use in therapeutic strategies. The research was conducted using normal human dermal fibroblasts (NHDF cells) that had been treated with caffeic acid at a concentration of 1 mmol/L and then exposed to a moderate-strength static magnetic field. The RNA that had been extracted from the collected cells was used as a template for next-generation sequencing (NGS) and an RT-qPCR reaction. We identified a total of 1,006 differentially expressed genes between CA-treated and control cells. Exposure of cells to a SMF altered the expression of only 99 genes. Simultaneous exposure to both factors affected the expression of 953 genes. It has also been shown that these genes mainly participate in cellular processes, including apoptosis. The highest fold change value were observed for HSPA6 and HSPA7 genes. In conclusion, the results of our research enabled the modulators, primarily caffeic acid and to a lesser extent a static magnetic field, of the apoptosis signaling pathway in human fibroblasts to be identified and to propose a mechanism of their action, which might be useful in the development of new preventive and/or therapeutic strategies. However, more research using other cell lines is needed including cancer cells.
