JAG1 and cancer: We moreover verified that protein levels for E-cadherin and P-cadherin, encoded by CDH1 and CDH3, respectively, as well as CD44 and Jagged1 proteins were elevated in H661-p190A cells relative to control cells and H661 cells expressing the aforementioned p190A cancer mutations with exception of CD44 protein in p190A(S229L) expressing cells (Fig. 4d).
