[Progress in the mechanisms of anticancer peptides].

In recent years, cancer has become a major concern in relation to human morbidity and mortality. Anticancer peptides (ACPs) are the bioactive peptide with antitumor activity and found in many organisms, including mammals, amphibians, insects, plants and microorganisms. ACPs have been suggested as promising agents for antitumor therapy due to their numerous advantages over traditional chemical agents such as low molecular masses, relatively simple structures, greater tumor selectivity, fewer adverse reactions, ease of absorption, a variety of routes of administration and low risk for inducing multi-drug resistance. Combining with the related research in our group, we summarized the mechanisms of ACPs to provide some directions for research and development of peptide-based anticancer drugs.
