[Abstract]:With the increasing incidence of cancer worldwide, cancer has become a major cause of death and a major public health problem. Anticancer peptides can destroy the structure of tumor cell membrane or inhibit the proliferation and migration of cancer cells, as well as the formation of tumor blood vessels, almost no hemolysis and no damage to normal human cells, which has become a hot spot in the research of new anti-tumor drugs. The main sources of anticancer peptides can be divided into four categories: antimicrobial peptides, such as lactoferrin Bu, daponin, have broad-spectrum and high efficiency inhibitory activity against bacteria and other microorganisms, and can inhibit the proliferation and growth of many kinds of cancer cells and induce apoptosis of cancer cells; Peptide hormones such as atrial natriuretic peptide (ANPP) and other peptides in the formation of ANP have the effects of increasing vascular permeability, lowering blood pressure, natriuretic, diuretic, relaxing vascular smooth muscle, regulating water and salt balance and inhibiting cell proliferation, etc. Recent studies have found that they can directly kill tumor cells or strongly inhibit the synthesis of DNA from cancer cells, thereby inhibiting the growth of cancer cells; polypeptide toxins such as bee venom, snake venom, scorpion venom and other highly toxic biotoxins, Endothelin inhibits the angiogenesis of tumor and inhibits the growth and metastasis of cancer cells. Anticancer peptides inhibit the proliferation of cancer cells by inducing cell apoptosis, destroying cell membrane structure, changing pH around or within cells and enhancing immune response. The origin and mechanism of anticancer peptides are reviewed, and the application prospect of anticancer peptides is analyzed in order to provide reference for further research and development of anticancer peptides.
