Figure 6: Effect of transient receptor potential channel inhibitor on the effects of isoliquiritigenin in 5637 cells. Cell viability was checked after co-treating 5637 cells with isoliquiritigenin plus (a) TG100-115 (transient receptor potential melastatin 7 inhibitor) or (b) tranilast (transient receptor potential vanilloid 2 inhibitor) for 24 h. Results are presented as mean ± standard error of the mean. ISL: Isoliquiritigenin; CTRL: Control. **P < 0.01 versus untreated controls.^#P < 0.05 for comparisons between treatments
