Description générale

Chemical structure: peptide

Application

Lactoferricin B, fragment 4-14 trifluoroacetate salt has been used to study effect of lactoferricin on cell proliferation of human colon cancer cells. It has been used in study of ultraviolet light-mediated DNA damage in human colon cancer cells.

Actions biochimiques/physiologiques

Lactoferricin B also suppresses liver and lung metastasis in murine melanomas and lymphomas. In addition, it causes cell death in human leukemic and carcinoma cell lines. It is effective against Escherichia coli, Salmonella enteritidis, Klebsiella pneumoniae, Proteus vulgaris, Yersinia enterocolitica, Pseudomonas aeruginosa, Campylobacter jejuni, Staphylococcus aureus, Streptococcus mutans, Corynebacterium diphtheriae, Listeria monocytogenes and Clostridium perfringens.
Antibiotic peptide in colostrum and milk that protects from bacterial infection at mucosal surfaces.

Treatment of Caco-2 cells with the peptide lactoferricin(4-14), results in reduction of the growth rate by prolongation of the S phase of the cell cycle. Lactoferricin(1-25) is formed in the gut by cleavage from lactoferrin and the bioactive amino acids
