CAV1 and cancer: Importantly, however, CAV1 also functions as a tumor suppressor by aiding E-cadherin in the sequestration of β-catenin, thereby impeding activation of the β-catenin/Tcf-Lef-dependent transcription of genes, like survivin, cyclooxygenase-2, cyclin D1, and many others that favor cancer development [140, 165, 166].
