K. Quantification of luciferase activity of midguts with indicated genotypes. Error bars show the SD of six independent experiments. Data information: Error bars represent SDs. p-values for lifespan curves (N) were calculated by the log-rank test. The statistical tests used in other panels were student's t-tests. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001, and non-significant (NS) represents p > 0.05.
