Epinecidin-1, a synthetic 21-mer antimicrobial peptide originally identified from grouper (Epinephelus coioides), specifically exhibited high antimicrobial activities against both Gram-negative and Gram-positive bacteria. In the current study we report on the in vitro cytotoxicity of the peptide, an important factor before it can be considered for further(More)
The antimicrobial peptide, tilapia hepcidin (TH) 2-3, belongs to the hepcidin family, and its antibacterial function has been reported. Here, we examined the TH2-3-mediated regulation of proinflammatory cytokines in bacterial endotoxin lipopolysaccharide (LPS)-stimulated mouse macrophages. The presence of TH2-3 in LPS-stimulated cells reduced the amount of(More)
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)(More)
Epinecidin-1 is an antimicrobial peptide present in the grouper (Epinephelus coioides). In this study, the antitumor activity of a synthetic epinecidin-1 peptide was tested. The in vitro results showed that epinecidin-1 inhibited the proliferation of human leukemia U937 cells and increased the ADP/ATP ratio after 24h of treatment. The DNA fragmentation(More)
