Human interferon β from HB1.F3.CD.IFN-β cell line prevented epithelial-mesenchymal transition (EMT) and metastasis in melanoma cell line (A375SM). To confirm the effect of recombinant interferon-β of HB1.F3.CD.IFN-β on EMT and metastasis, the melanoma cell line (A375SM) was cultured with conditioned media from HB1.F3.CD.IFN-β for 0, 24, 48, and 72 hours. Expressions of epithelial protein E-cadherin, mesenchymal protein Slug, and metastasis protein cathepsin-B were measured by western blot. (A) The melanoma cell line was cultured with conditioned media from the HB1.F3.CD cell line as a control. (B) The melanoma cell line was cultured with conditioned media from HB1.F3.CD.IFN-β cell line. Data are displayed as the mean±standard deviation of three distinct experiments each conducted in triplicate. *p < 0.05 vs. 0 hour. GAPDH, glyceraldehyde 3-phosphate dehydrogenase.
