USP11 and breast cancer: These results show that overexpression of E-cadherin in mammary tumor cells does not induce the expression of β-catenin or α-catenin, nor rescues the reduction of β-catenin or α-catenin by Usp11 deficiency, which suggests that Usp11 deficiency reduces the expression of β-catenin or α-catenin independent of the decrease of E-cadherin.
