What Kind of Animals Can Be Significant in Human Health?
Based on recent foreign media reports, spider goats can be used to make artificial silk, which will attract increasing concerns in scientific groups around the whole world. Referring to the “drug development”, people may immediately think of mass scientists who wear a white lab coat standing in front of the table to do experiments, with a variety of test tubes and petri dishes.
However, a variety of animals have made an important contribution for the development of modern science, including sequencing technology, peptide synthesis of ghk-cu, recombinant techniques, and so on. Almost everyone has heard of the story of Spiderman, but has anyone ever heard of a spider goat?
In fact, the genetically modified goats are unique because they produce ordinary spider silk. The same substances that make up the cobweb are produced by their mammary glands. Many scientists have taken spider silk as a kind of “biosteel”. As shown in the film, spider silk has a strong tensile strength. The researchers said that if a lot of spider silk twisted into a rope, it is strong enough to be made bulletproof vest, parachute rope, aircraft and some other equipment. In addition, spider silk can also be made into artificial ligaments and artificial tendons, supporting tissue, bone and nerve cells to remain stable during growth. As the cell grows, these rayon parts gradually break down. But why is the goat? Spiders and silkworms are different, which means spiders together will erode each other.
“Conceptually, this process is very simple,” said Randy Lewis, a molecular biologist at the University of Wyoming, who helped “produce” the goats. “The spider silk gene used for silk proteins is associated with the DNA of the goat that controls the organization of the protein. In this case, it is the mammary gland, formed only during lactation, and then the cells combine with the egg to produce the embryo, so the embryo has genes to synthesize its DNA, and when the ewe begins to secrete the milk, the silk protein is produced.” The process is similar to Gonadorelin in peptide synthesis, which is also beneficial to human health.
Certainly, there are some other creatures who are significant to human health care. Taken cone snails as an example, one of the most dangerous creatures in nature, their venom can cause death. Do not be fooled by its beautifully vortexed and mottled shells or their steady nature. Whereas, some of these compounds may be useful if used appropriately. Cone snails belong to the family of fish-eating mollusks, which, by muscle contraction, can release venom to the prey through, filled with venom of the harpoon from the beak, and the venom can instantly paralyze the nearby fish.
Actually, there are not many mechanisms available for catching prey, and they probably use more of their venom as a weapon than most other creatures. They use venom to protect themselves. While on the other hand, their venom contains about 150 to 200 different compounds, which may be unique in other animals or creatures. The diversity of compounds provides researchers with a pharmacology laboratory to study various compounds such as Exenatide. Other potential applications of their venom compounds include the treatment of neuropathic pain, epilepsy, heart disease and stroke.
However, scientific discovery is much more than that. Recently, a new kind of sponge polyketone that can inhibit protein synthesis can effectively kill cancer cells. Developing a fundamental understanding of the links between animals and the chemicals could be necessary, which requires further research and mass trials, enabling to develop new and effective therapy.
