Invasive colon cancer but not non-invasive adenomas induce a gradient effect of Wnt pathway receptor frizzled 1 (Fz1) expression in the tumor microenvironment

摘要

BackgroundWnt signaling in the colon cancer tumor microenvironment (TME) may affect cancer biologic properties including invasion and metastatic dissemination. Prior reports have suggested that the expression of select frizzled (Fz) receptors may be altered in cancers and in the TME.
