(A) Effects of EGS on expression levels of GFP mRNA in PD4251 worms. Shown is the GFP mRNA expression level, as measured by QPCR. (B) Effects of EGS on expression levels of Ngfp and Mtgfp proteins in PD4251 worms treated with EGSs. Shown are the Ngfp and Mtgfp protein expression levels, as measured by Western-blot analysis. Actin protein was used as an internal control.
