RESUMO
Malignant tumor is a disease that severely threaten human health. Common chemotherapeutical drugs currently used in clinical practice have some problems in severe side effects and chemoresistance. In contrast, natural venom peptides and artificially designed targeting peptides have excellent biological activities and potential druggability due to their small molecular weights and high affinity to tumor tissues. Thus, the methods for the discovery of anti-tumor peptides have attracted much attention. In this paper, we summarized the types of anti-tumor peptides from recent literatures. Then, we systematically reviewed screening theories, methods and applications based on traditional chromatographic separation, peptidomics, phage display, phenotypic screening, and artificial intelligence. These strategies and technologies will provide a methodological reference for accelerating anti-tumor peptides research.
RESUMO
Aim To evaluate whether the combination of polypeptide AP25 and docetaxel is more efficient in treating experimental breast cancer,than either reagent used alone,and to offer suggestions for clinical use. Methods An experimental breast carcinoma model was set up to investigate the anti-tumor effects of AP25 and docetaxel combination.The Q value was caluculat-ed by Guinness rules and the anti-tumor effects of the combination of polypeptide AP25 and docetaxel were e-valuated.Results The treatment by the combination of polypeptide AP25 and docetaxel showed a better tumor inhibition rate.The combination of AP25 20 mg ·kg -1 and docetaxel 10 mg·kg -1 significantly inhibi-ted the tumor growth with 0.85 1.15,showing a synergistic effect.Conclusions The combination of AP25 and docetaxel can significantly in-hibit the tumor growth with a synergistic effect and de-crease the dose of chemotherapy.
