wuIs177 [ftn-1p::GFP + lin-15(+)]. GFP expression in the intestine. ftn-1p::GFP transgene shows moderate basal expression under standard culture conditions in an otherwise wild-type background, but is strongly induced by reduced insulin/IGF-1 signalling, reduced HIF signalling, and increased free iron levels.
