"We assessed the effect of knockdown of these 10 genes on ER homeostasis by RNAi treatment in a zcIs4 transgenic strain harboring the
hsp-4 promoter-driven GFP transgene that exhibits ER stress-dependent induction of GFP fluorescence." Y39G10AR.8 RNAi resulted in decreased expression of the Phsp-4::GFP transgene (Table 1)
