Antimicrobial peptides have been shown to exert cytotoxic activity towards cancer cells through their ability to interact with negatively charged cell membranes. In this study the cytotoxic effect of the antimicrobial peptide, LfcinB was tested in a panel of human neuroblastoma cell lines. LfcinB displayed a selective cytotoxic activity against both(More)
Cationic antimicrobial peptides (CAPs) exhibit promising anticancer activities. In the present study, we have examined the in vivo antitumoral effects of a 9-mer peptide, LTX-302, which is derived from the CAP bovine lactoferricin (LfcinB). A20 B cell lymphomas of BALB/c origin were established by subcutaneous inoculation in syngeneic mice. Intratumoral(More)
Several components of blood, e.g. lipids, coagulation and fibrinolytic factors, are thought to be important risk factors in cardiovascular diseases. The aim of this study was to correlate these risk factors and the soluble adhesion proteins, soluble P-selection (sP-selectin) and soluble vascular cell adhesion molecule (sVCAM-1), in healthy men and women as(More)
In a structure-antibacterial activity relationship study of a peptide fragment of bovine lactoferricin consisting of FKCRRWQWRMKKLGA (LFB 17-31), it was revealed that the two Trp residues were important for antibacterial activity. It has further been demonstrated that the size, shape and the aromatic character of the side chains were even more important(More)
BACKGROUND Bovine lactoferrin (LFB) and its pepsin-generated peptide lactoferricin (LfcinB) possess antitumor activities. The mechanism underlying the antitumor activities of LfcinB in vivo has not been elucidated. In this study the antitumor activities exerted by LFB, LfcinB and murine lactoferricin (LfcinM) on murine tumor cell lines and experimental(More)
Oncolytic immunotherapies represent a new promising strategy in the treatment of cancer. In our efforts to develop oncolytic peptides, we identified a series of chemically modified 9-mer cationic peptides that were highly effective against both drug-resistant and drug-sensitive cancer cells and with lower toxicity toward normal cells. Among these peptides,(More)
Biological activities of peptides representing two different regions in the TNF molecule were investigated. We have earlier reported that one of the peptides studied, TNF 36-62, induced chemotaxis in granulocytes and monocytes. TNF 41-62, a shorter analog of TNF 36-62, possessed similar chemotactic effects. Both peptides caused a weak enhancement of LPS(More)
