  Development of treatment resistance and lack of specificity are common problems in cancer chemotherapy, resulting in diverse and negative side effects. Emerging studies have shown that certain anti-microbial peptides (AMPs) have a destructive effect on cancer cells but no effect on normal eukaryotic cells. We isolated a cationic antimicrobial peptide--Cecropin B from silk worms infected with staphylococcus aureus and investigated its effects on breast cancer growth in vitro and in vivo. Treatment with Cecropin B induced cell death of murine breast cancer cells but not of normal nonmalignant cells. Cecropin B inhibited cancer cell proliferation as compared with control. Cecropin B treatment increased gene expression of Caspase3, Fas and high mobility group box 1 (HMGB 1). Administration of Cecropin B in vivo reduced tumor growth. In conclusi.. Read More»
