Aprotinin is a nonspecific serine protease inhibitor, which can inhibit plasminogen-plasmin system and matrix metalloproteinases. Aprotinin has been investigated as an antitumor agent. However, its antineoplastic effects on breast cancer (BC) have not been investigated yet. The objective of this study was to assess the inhibitory effects of aprotinin on human BC cell lines. We assessed the effects of aprotinin on local invasion and survival of human BC cell lines MDA-MB-231, SK-BR-3 and MCF-7 in vitro. CHEMICON cell invasion assay kit was used to assess local invasion, and (3-(4,5-dimethylthiazol2-yl)-2,5-diphenyltetrazolium bromide) tetrazolium reduction (MTT) assay was used to determine the antiproliferative activity of aprotinin. Human dermal fibroblast (HDF-1) cell line was used as control normal cells. Cancer cell lines showed more invasion characteristics compared to HDF-1. Aprotinin significantly decreased the invasiveness of MDA-MB-231 in concentrations of 1 trypsin inhibitor unit (TIU)/mL, 1.3 TIU/mL and 1.7 TIU/mL in comparison with the untreated group (analysis of variance (ANOVA) p < 0.001). Treatment of SK-BR-3 with 1.3 TIU/mL aprotinin caused no significant reduction in invasiveness (p = 0.06). Treatment with diff...Continue Reading
