Figure Lengend Snippet: (A) A western blot analysis of lysates from AML12 mouse hepatocytes challenged with Smoothened agonist (SAG) for the indicated times. Insulin treatment is a positive control for AKT phosphorylation. (B–G) Quantification of western blot images for the indicated phosphoproteins relative to their total protein levels (mean ± SEM; * p < 0.05; ** p < 0.01; n.s., not significant; t test). The GLI1 protein is normalized to actin levels. Either the 10- or 15-min time point was used for quantification (see ). (H) A western blot analysis of lysates from cells transfected with either mock or Rictor siRNAs and challenged with vehicle, 0.5 μM SAG (15 min), or 100 nM insulin (30 min). (I) DEGs in the rict-1(mg360) mutant compared to the grd triple mutant (hypergeometric p value reported). (J) A scatterplot showing the differential expression values for the rict-1(mg360) mutant plotted against the grd mutant ( rict-1 -specific DEGs in red, grd -specifc DEGs in blue, and rict-1/grd co-regulated genes in black). R 2 values are reported for linear regression analyses on the union and intersection of the rict-1 and grd DEG datasets. (K and L) (K) Representative images (scale bar, 50 mm; white arrowheads indicate nuclei) and (L) quantification of DAF-16::mKate2 and GFP::PQM-1 nuclear fluorescence in day 1 adult WT and grd mutant animals reared at 20°C (mean ± SD; **** p < 0.0001; t test). (M) The average DAF-16 (left) or PQM-1 (right) enrichment (ChIP-seq signal) at the transcriptional start site (TSS) at all genes (red) or at genes differentially expressed in the grd mutant (black).
