Figure 4. (A, B) The results of detecting the binding of PUM1 to Cripto-1 by GST pull-down and CO-IP experiments. (C) The results of the protein expression levels of PUM1 and Cripto-1 in each group in which the expression level of PUM1 was regulated by gene editing. The symbol * means p < 0.05 compared to p-NC group. The symbol # means p < 0.05 compared to si-NC group.
