IL6 and atrial fibrillation: Acute exposure of AF cells to CTS at 0.1 Hz did not alter inflammatory cytokine gene expression (tumor necrosis factor alpha, Tnfα; interleukin 1 beta, Il‐1β; interleukin 6, Il‐6) or candidate mechanosensitive gene expression (cytochrome c oxidase subunit 2, Cox2; MYC proto‐oncogene, Myc; Fos proto‐oncogene AP‐1 transcription factor subunit, Fos) compared to unloaded controls (Figure 6C, D).
