The platypus is the sole living representative or monotypic taxon of its family and genus, though a number of related species appear in the fossil record. A large range of useful molecules have already been identified in snake venom, and many of these are currently in use in human medicine. The platypus ,3 sometimes referred to as the duck-billed platypus,4 is a semiaquatic, egg-laying mammal endemic to eastern Australia, including Tasmania. Secreted in the gut, GLP-1 ultimately lowers blood sugar levels by making its way through the blood stream to the pancreas. These compounds serve as metabolic hormones that stimulate a decrease in blood glucose levels. Functional studies and pharmacological evaluation of the identified toxins will then lay the foundations for the future development of novel biomedical substances. GLP-1 Found in all mammals, glucagon-like peptide-1 (GLP-1) belongs to a family of biomolecules called incretins. Guided by this bioassay, we identified 11 novel peptides, including the heptapeptide H-His-Asp-His-Pro-Asn-Pro-Arg-OH (1). We previously found that its crude venom potently induces Ca (2+) influx in human neuroblastoma IMR-32 cells. ![]() (Photo: Biodiversity Heritage Library/CC BY 2.0) According to Ann Moyal’s book Platypus, theories. Home > Animals > Mammals > Duck-billed Platypus Duck-billed Platypus When first discovered it was so odd that it was thought to be a hoax. The duck-billed platypus (Ornithorhynchus anatinus) is one of the few venomous Australian mammals. We propose that such construction and analysis of mammalian venom transcriptomes from small samples of venom gland, in tandem with proteomics studies, will allow the identification of the full range of mammalian venom components. A platypus depicted as a duck mole from the 1880 title Johnson’s Household Book of Nature. Platypuses bear a beaver tail, venomous spurs (males only), a duckbill, webbed feet, and fur, as well as being one of the only mammals to lay eggs. Here we describe the status of current research into the venom of the platypus, a semi-aquatic egg-laying Australian mammal, and discuss our approach to platypus venom transcriptomics. Only five mammalian species are known to be venomous, and while a large amount of research has been carried out on reptile venom, mammalian venom has been poorly studied to date. ![]()
