Application of XAV939 or Wnt-c59 with FGF2 blocks the accumulation of nuclear b-catenin in MGPCs, and increases levels of p38MAPK in Muller glia, whereas levels of cFos are unaffected. a, b, Eyes were injected with four consecutive daily injections of FGF2 6 XAV939 or Wnt-c59, BrdU 24 h after the last injection of FGF2, and retinas harvested 24 h later. Wnt-c59 (treated). a, b-catenin in the nuclei of Sox91 Muller glia/MGPCs on 70% grayscale background.

Nestin silencing inhibits the Wnt/β-catenin signaling in breast CSC. Nestin-si and Nestin-c breast CSC were cultured for 48 h, and the relative levels of target proteins and phosphorylation were determined by western blotting. Data are presented as the mean ± SD of the levels of target proteins vs. the β-actin control, or the phosphorylated vs. the total form, from six separate experiments. In addition, Nestinhigh in the presence or absence of LGK974 (1 nM), Nestinlow in the presence or absence of SB216763 (5 uM), and control CSC were tested for their proliferation via mammosphere formation assays. Quantitative analysis of the formed mammospheres. *P <0.05, vs. the Nestin-c or control, except for specifically indicated. CSC, cancer stem cell; SD, standard deviation.
