Description

A small molecular polypeptide of shark cartilage angiogenesis inhibitory factor and its production and purification method and application technical field The invention relates to the field of small molecule peptides, in particular to a small molecule polypeptide of shark angiogenesis inhibitory factor and its production and purification method and application. Background technique Sharks are one of the marine animals that rarely suffer from malignant tumors, and the incidence rate is one in a million. American scientist Luer injected a high dose of aflatoxin B1, a strong carcinogen, into sharks, but it could not induce cancer in sharks. Inoculating sharks with cancer cells also failed to induce cancer. This suggests that sharks have a unique anti-tumor mechanism (He Lihong 1, Huang Jianhua 2, Shen Songdong et al., Marine Science / 2005 / Volume 29 / Period 11: 63-66). Over the years, researchers from all over the world have mostly studied shark cartilage tissue, and isolated...
