On the other hand, analysis of tumors (n=150), including metastatic tumors (n = 19), detected a similar positive correlation between expression of Slug and c-Jun (r = 0.39, P = 1.016e-06) and a modest positive correlation between expression of Slug and cyclin D1 (r = 0.22, P = 0.00595) (Supplementary Figure S4). This evidence concerns the gene JUN and metastatic neoplasm.
