A tetrameric peptide derived from bovine lactoferricin as a potential therapeutic tool for oral squamous cell carcinoma: A preclinical model.

ABSTRACT: Oral squamous cell carcinoma is the fifth most common epithelial cancer in the world, and its current clinical treatment has both low efficiency and poor selectivity. Cationic amphipathic peptides have been proposed as new drugs for the treatment of different types of cancer. The main goal of the present work was to determine the potential of LfcinB(20-25)4, a tetrameric peptide based on the core sequence RRWQWR of bovine lactoferricin LfcinB(20-25), for the treatment of OSCC. In brief, OSCC was induced in the buccal pouch of hamsters by applying 7,12-Dimethylbenz(a)anthracene, and tumors were treated with one of the following peptides: LfcinB(20-25)4, LfcinB(20-25), or vehicle (control). Lesions were macroscopically evaluated every two days and both histological and serum IgG assessments
