Sodium arsenite promotes escape behavior in C. elegans via TPH-1. (a) Escape behavior of N2 and tph-1(mg280) C. elegans exposed to 0 and 0.2-mM sodium arsenite for 8, 12, and 24 h. (b) 8-h avoidance index. (c) 12-h avoidance index. (d) 24-h avoidance index. (e) Turning index (the comparison between the two groups was conducted using Student's t-test). (∗p < 0.05, ∗∗p < 0.01, ∗∗∗∗p < 0.0001, and ns p < 0.05).
