British research finds that frog skin extract can fight cancer

The field of cancer biotherapy has always been a new direction of cancer treatment Compared with chemical therapy, biotherapy has incomparable advantages, no side effects on human body, and can enhance human immunity It is a new trend in the field of cancer treatment in recent years When we were in primary school, our teacher told us that frogs are beneficial insects and the God of crop protection, so that everyone can protect our friends Recently, British scientists have found another great benefit in these cute little things - two kinds of proteins in the sticky and slippery skin can prevent the growth of cancer cells, which brings new hope for cancer patients The skin protein extracted from frogs and toads can inhibit cancer growth, according to the Daily Telegraph website, which was discovered by pharmacists at Queen's University in Belfast after studying the skin of frogs and toads Among the proteins extracted from the skin of frogs and toads, they found that two kinds of proteins can cut off the blood needed for the growth and spread of cancer cells, and prevent the growth of blood vessels in tumors "When most malignant tumors grow to a certain size, usually 3 mm, they need blood vessels to grow into the tumor to provide the necessary oxygen and nutrition, so curbing the growth of blood vessels will also prevent the spread of the tumor and eventually lead to the killing of the tumor," Chris Shaw, the leader of the research group and professor of Queen's University of Belfast, told Indian media Say During the clinical trial, the vaccine is expected to come out four years later The researchers said that they have carried out experiments on mice The results show that regular injection of proteins from frog skin into mice can slow down the growth of blood vessels in tumors "Because this treatment is targeted and uses only natural proteins, it is almost non-toxic and has few side effects," professor Chris said They have received a considerable bonus for this research result, which can promote their research and development to continue At the same time, the British and Indian governments have also supported the research, which may accelerate the research and development of new drugs based on the research results The R & D team worked with the India's National Institute of immunology in New Delhi to prepare for the human clinical trial phase Professor avadhesha surolia of the National Institute of immunology of India said in an interview with the media that he had extracted a large number of the polypeptide protein from frogs around the world and expected to use it in human trials within four to six months Some of them have been used to treat ovarian cancer, and the other part has been determined to treat cervical cancer "We hope that therapeutic vaccines will be available in the next four years," suloria said.
