In case of breast cancer, GSE9195 and GSE1456-GPL96 sets provided data that patients with decreased expression of TAP1 gene (n = 57 and n = 139 respectively) had significant higher relapse-free survival in comparison with the ones with a greater expression of TAP1 (n = 20, for both) (Fig. 7A, 7B). Here, TAP1 is linked to breast carcinoma.
