TFF1 and neoplasm: To explore the association of Myh9 with expression of Ctnnb1 and Wnt/β-catenin-targeted genes, we performed qPCR on the tumor tissues listed above and found that conditional hMYH9 expression in Tff1-/- mice upregulated the expression of Wnt/β-catenin targeted genes, while conditional Myh9 knockout in Tff1-/- mice significantly downregulated the expression of Wnt/β-catenin targeted genes (Figure S21E, S21F).
