In addition, we found that the expressions of FOXM1, ADAM17, NOTCH1 and N-cadherin were decreased in SPAG5-downregulated tumor tissues, while E-cadherin expression was increased, highlighting the role of SPAG5 in downregulation of the expression of FOXM1, ADAM17 and NOTCH1, and inhibiting EMT. Here, ADAM17 is linked to neoplasm.
