Figure 3. Wnt ligand/EGL-20 is required for cell-non-autonomous UPR^mt induction in animals with Q40∷YFP expression in neurons.

(A) Representative photomicrographs of D2 adult animals expressing neuronal Q40∷YFP; hsp-6p∷gfp in WT or egl-20 animals.

(B) Quantification of hsp-6p∷gfp expression. The genotypes are as in (A).

(C) Immunoblots of GFP expression. The genotypes are as in (A).

(D) Representative photomicrographs of D2 adult animals expressing neuronal Q40∷YFP; DVE-1∷GFP in WT and egl-20 animals. Arrows highlight the DVE-1∷GFP signal localized in the intestinal nuclei.

(E) Quantification of the number of intestinal nuclei with DVE-1 puncta. The genotypes are as in (D).

(F) Representative photomicrographs of D1 animals expressing hsp-6p∷gfp in WT or egl-20 animals grown on EV or cco-1 RNAi from hatching.

(G) Quantification of hsp-6p∷gfp expression. The genotypes are as in (F).

(H) Representative photomicrographs of hsp-6p∷gfp expression in neuronal specific cco-1 RNAi animals in WT or egl-20 background.

(I) Quantification of hsp-6p∷gfp expression. The genotypes are as in (H).
