We also confirmed that staurosporine decreased nuclear MYH9 phosphorylation at S1943 to inhibit the MYH9-CTNNB1 axis-mediated canonical Wnt/β-catenin signaling activation in cell lines and in the GC mouse models (orthotropic xenograft GC mouse models and conditional transgenic GC mouse models). This evidence concerns the gene CTNNB1 and gastric cancer.
