Figure Lengend Snippet: The effects of flavonoid compounds on recombinant TMEM16A currents in CHO cells. (A) Chemical structures of flavonoids. (B) Chemical structures of tannic acid. (C) The time course for the effects of luteolin (Lute), galangin (Gala), quercetin (Quer) and fisetin (Fise), all at 100 μM and DMSO (0.1%) on TMEM16A currents tested at +100 mV. The protocol was shown at the top of the figure. (D) The representative current traces recorded when the effect of drugs has stabilized. (E) The inhibition by flavonoids (100 μM), DMSO (0.1%), tannic acid, T16Ainh‐A01 and CaCCinh‐A01 (100 μM) of TMEM16A current tested at +100 mV. NS, not significant; *P < 0.05, significant effect of treatments.

Article Snippet: CHO cells, LA795 cells, HEK293 cells and normal lung 2BS cells were cultured in F‐12K (Solarbio, China) (1% nonessential amino acids, 600 μg·mL −1 G418), RPMI 1640 (Solarbio, China) or DMEM medium (Solarbio, China) supplemented with 10% fetal bovine serum (Gibco, USA) and antibiotics (100 IU·mL −1 penicillin G and 100 mg·mL −1 streptomycin; Solarbio, China) in a humidified incubator at 37°C and 5% CO 2 .

Figure Lengend Snippet: The effects of luteolin (Lute), galangin (Gala), quercetin (Quer) and fisetin (Fise) on I–V relationship and deactivation kinetics of TMEM16A currents in CHO cells. (A) Representative traces of TMEM16A currents recorded using the voltage protocol indicated at the top of B. Dotted lines indicated the zero current level. The effects of luteolin, galangin, quercetin and fisetin (all at 100 μM) or tannic acid (100 μM) are shown. (B) Normalized current–voltage relationships of TMEM16A currents in the absence or presence of the compounds; n = 5 for each experimental group. (C) The effects of luteolin, galangin, quercetin and fisetin on the deactivation kinetics of TMEM16A currents from +100 to −100 mV. The red line shows the deactivating currents in the presence of the compounds, which were scaled up to match the amplitude of the deactivating currents in the absence of the compounds. (D) Summary of effects of luteolin, galangin, quercetin and fisetin on the time constants of TMEM16A deactivating currents. *P < 0.05, significantly different from control, n = 5 for each experimental group.

Figure Lengend Snippet: The concentration–response relationships for luteolin (Lute), galangin (Gala), quercetin (Quer) and fisetin (Fise) on recombinant TMEM16A currents in CHO cells. (A) The time course for the effects of galangin (1–100 μM) on TMEM16A currents tested at +100 mV. (B) The representative current traces recorded when the effect of different concentrations of galangin had stabilized. (C) Concentration–response relationships for luteolin, galangin, quercetin and fisetin on TMEM16A currents recorded at +100 mV. Data were fitted with logistic function. Luteolin: n = 5, 5, 5, 5 and 8; galangin: n = 5, 5, 9, 5 and 7; quercetin: n = 5, 5, 5, 7 and 9; fisetin: n = 5, 5, 5, 6 and 9 (1, 3, 10, 30 and 100 μM).
