IL6 and colorectal carcinoma: Myocytes pre-incubated with IL-6 and subsequently superfused with AZM (1-times CRC, 41.5 mg/L) and HCQ (0.1 or 0.5 or 1-times CRC, 5.0 or 24.9 or 49.8 mg/L) for 5–8 min periods for each concentration, significantly decreased ICaL, INa and IKr densities in a concentration-dependent manner (Fig. 5b,c,e–l and Table 3A).
