Fig. 1. hsd-1 expression in the XXX cells globally regulates DAF-16
activity. (A-C) hsd-1 is exclusively expressed in the paired XXX
cells of the head. (A) Phsd-1::GFP expression. (B)
Psdf-9::RFP expression in the XXX cells. (C) Merged image
showing that Phsd-1::GFP co-localizes with Psdf-9::RFP.
(D-F) Level of DAF-16::GFP nuclear localization. Anterior of animal indicated
by the arrows. (D) Diffuse (cytoplasmic) GFP in wild-type control L2
larva. Partially diffuse and punctate (nuclear) GFP (E) and almost
entirely punctate GFP (F) in hsd-1(mg433); ncr-1(nr2022) L2d
larvae.
