Figure 1. The effect of dusp7 knockdown on the lifespan of Drosophila. (A) The dusp7 expression level when RU486 was added to induce dusp7 knockdown (*** p<0.001; > means hybridization). (B) The lifespan curve when dusp7 was knocked down in Drosophila. (C) The lifespan curve under specific knockdown of dusp7 in the Drosophila intestinal track.
