?S3) when compared to all other wave forms. Resiquimod At 150?mV/mm and 60?Hz, keloid fibroblasts subjected to DW stimulation underwent higher level of apoptosis than by AC stimulation (Supporting Information Fig.?S3d2). The cytotoxic effects of high electric field stimulations by AC and DW on keloid fibroblasts were significantly higher than for normal cells. DW was demonstrated to be the least cytotoxic to normal fibroblasts when compared to all other stimulations. Amongst all forms of ES, collagen I gene expression in keloid fibroblasts was shown to be the highest by AC treatment at 20 and 150?mV/mm at 10?Hz (Fig.?2a1, c1). PAI-1 pathway was also upregulated by AC stimulation at 20?mV/mm and 10?Hz (Fig.?2a2). At 75?mV/mm and 10?Hz electric field, collagen I gene was increasingly expressed with time by DW and AC (Supporting Information Fig.?S4c1). But when the frequency was increased to 60?Hz, the expression of collagen I gene in keloid fibroblasts was significantly downregulated, and this appeared more by AC than DW (Supporting Information Fig.?S4d1). During AC stimulation at 150?mV/mm and 10?Hz electric field, keloid fibroblasts exhibited the same collagen 3-MA order I gene expression pattern as in 20?mV/mm and 10?Hz. But collagen I gene was downregulated and apoptosis for keloid fibroblasts was increased when the frequency was increased to 60?Hz. This was also observed for DW (Fig.?2d1). Collagen I and PAI-1 syntheses were increased at 150?mV/mm by DC stimulation more than AC and DW for both normal and keloid fibroblasts. The activity of voltage-gated calcium ion channel gene showed a statistically significant difference (P?Compound Library supplier 60?Hz by DW and AC stimulations, (Supporting Information Fig. S5a, b), when compared to stimulations at 10?Hz. This emphasizes the variation in gene expression at different frequencies, even at the same electric field strength. Normal and keloid fibroblasts increased the level of collagen production by all stimulations at 150?mV/mm and 10?Hz, when compared to cells without ES. But the effect was decreased when subjected to ES at 150?mV/mm and 60?Hz. Therefore, it appears that type I collagen synthesis is highly dependent on the applied frequency of ES.
