Venomous creatures have long been a source of fascination and fear, but they also hold the key to groundbreaking medical discoveries. Mandë Holford, a renowned scientist and professor, has dedicated her career to studying the deadly venom of marine snails and cephalopods, with the ultimate goal of developing life-saving drugs. Her journey began with a simple video of a snail hunting a fish, which sparked her interest in the potential of venom as a natural drug factory. Holford's research focuses on the Terebridae family of marine gastropods, known as 'auger snails', and their venom-producing glands. These snails use venom to hunt and kill their prey, delivering it through a proboscis with harpoon-like teeth. The venom is a complex mixture of peptides, which have evolved over 500 million years to target specific biological systems with ruthless efficiency. Holford's work has revealed the incredible diversity and potential of venom, with many genes being co-opted from 'housekeeping' functions to become powerful weapons. The study of venom has led to the discovery of numerous potential treatments for human diseases, including painkillers, cancer therapies, and blood thinners. Holford's team has patented several discoveries, such as the ability of a terebrid snail peptide to inhibit liver cancer cell proliferation. She has also launched VenomsBase, a platform to integrate venom data and create a more open research ecosystem. Holford's passion for science began at a young age, with her parents taking her to the American Museum of Natural History as a child. She initially believed science was about memorizing facts, but a summer job in a chemistry lab sparked her interest in discovery. Holford's work combines chemistry and biology, using nature's own tools to create new medicines. Her research agenda, 'mollusks to medicine', aims to unlock the secrets of venom and harness its power for human benefit. Holford's dedication to science and her commitment to promoting diversity in STEM make her a true pioneer in her field.
