ASK reduces invasiveness of BCa cell lines. UMUC-3, RT4 and T24 cells (50,000 cells/well) were transfected with Andes-1537 or ASO-C or left untreated (NT) for 48 h. (A) Invasion was determined with Matrigel Transwell Assay. (B) A triplicate analysis showed that ASK induces a drastic and significant reduction of invasiveness in all 3 cell lines. *p<0.05, **p<0.01. (C) UMUC-3 cells transfected as in (A) for 48 h were collected and total lysate was subjected to Western blot analysis of E-cadherin (E-cad), N-cadherin (N-cad) and Matrix Metallopeptidase 11 (MMP), using GAPDH as loading control. ASK induces down regulation of N-cadherin and MMP11.
