The effect of sodium arsenite on the expression of TPH-1 in ADF and NSM neurons of C. elegans. (a) Expression of TPH-1 in ADF neurons of C. elegans after exposure to sodium arsenite. (b) Quantitative analysis of ADF fluorescence intensity. (c) Quantitative analysis of NSM fluorescence intensity (the comparison between the two groups was conducted using Student's t-test). (∗∗∗∗p < 0.0001 and nsp > 0.05).
