In this Time Machine post, we travel back to 1938 to check out a manuscript on the importance of amino acids in nutrition authored by Dr. William Cumming Rose (1887-1985), professor of biochemistry at the University of Illinois, published in Physiological Reviews. His research on the importance of amino acids in the physiology of an organism culminated in 124 research, review or biographical articles and his receipt of the National […]
Phoenixin-20 is a small peptide that has been detected in mammals, birds, amphibians and fish. Studies have shown that it can modify reproductive processes in female mammals and fish. In addition, it has been shown in mammalian studies to act as a pain reducer and modulator of food intake. In a new study published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology, researchers explored whether phoenixin-20 has […]
Leptin is a hormone that signals the brain to suppress appetite in humans. While researchers at the University of Michigan described a similar appetite regulating role for leptin in South African clawed frogs (Xenopus), they also discovered that leptin signals limb development in tadpoles. They suspect that this happens once there are sufficient energy stores to begin the process of metamorphosis. Shalitin and Kiess (2017) also described a role for leptin in skeletal development of children and researchers implicate leptin in […]
