Figure 7. STL-1 resides at mitochondria and is regulated by SKN-1. The fluorescence of (A,B) STL-1::GFP from a Pglr-1::STL-1::GFP transgene, and (C,D) TOM20::mCherry from a Pglr-1::TOM20::mCherry transgene, was observed in (A,C,E) command interneuron cell bodies, including PVC, and (B,D,F) ventral cord neurites of wild-type animals. (E,F) Merged images. The fluorescence of (G) STL-1::GFP from a Pstl-1 ::STL-1::GFP transgene was observed in the hypodermal epithelia of wild-type animals stained with (H) MitoTracker Red. (I) Merged image. (J) Mean levels of
stl-1 mRNA (relative to wild type) as measured by qRTPCR in the indicated genotypes and conditions. Red bars indicate normoxia, blue bars indicate anoxia, and gray bars indicate paraquat treatment. Bar, 5 mm.
