In presence of DTT, only five of carvacrol-sensitive cells responded to hemin. In addition, the redoxinsensitive mutant hTRPA1-3C displayed a decreased hemin-induced calcium influx as compared to wildtype hTRPA1 (Figure 7C,D, n = 612, 14 hemin-sensitive cells). In patch 12 Tazemetostat-d8 custom synthesis exclamp experiments nonetheless, 1 M hemin failed to induce membrane currents in cellsof 17 pressing hTRPA1 (Figure 7E, n = six). Finally, hemin didn’t potentiate carvacrol-induced inward currents on hTRPA1 (Figure 7F,G, n = 12, paired t-test, p = 0.07).Figure 7.
