A fish antimicrobial peptide, tilapia hepcidin TH2-3, shows potent antitumor activity against human fibrosarcoma cells
چکیده انگلیسی

As part of a continuing search for potential anticancer drug candidates from antimicrobial peptides of marine organisms, tilapia (Oreochromis mossambicus) hepcidin TH2-3 was evaluated in several tumor cell lines. The results indicated that TH2-3, a synthetic 20-mer antimicrobial peptide, specifically inhibited human fibrosarcoma cell (HT1080 cell line) proliferation and migration. The way in which TH2-3 inhibited HT1080 cell growth was then studied. TH2-3 inhibited HT1080 cell growth in a concentration-dependent manner according to an MTT analysis, which was confirmed by a soft-agar assay and AO/EtBr staining. Scanning electron microscopy revealed that TH2-3 caused lethal membrane disruption in HT1080 cancer cells, and a wound healing assay supported that TH2-3 decreased the migration of HT1080 cells. In addition, c-Jun mRNA expression was downregulated after treatment with TH2-3 for 48–96 h compared to the untreated group. These findings suggest a mechanism of cytotoxic action of TH2-3 and indicate that TH2-3 may be a promising chemotherapeutic agent against human fibrosarcoma cells.
