In two tumors expressing DUSP28 (#1 and #2), levels of the N-cadherin and phospho-FAK, phospho-ERK1/2, and phospho-p38 proteins were quite higher in b fractions than those in a fractions, whereas no difference was detected between a and b fractions in DUSP28-reduced tumor sample (#3) (Fig. 6F). Here, PTK2 is linked to neoplasm.
