Xu and colleagues found that MSC-derived exosomal miR-133b inhibited proliferation, migration, and invasion of U87 glioma cells by decreasing EZH2 expression in vitro and inhibited tumor growth in vivo via modulating the Wnt/β-catenin signaling pathway by inhibiting the expression of EZH2 (136). The gene discussed is EZH2; the disease is glioma.
