Understanding growth signals

Growth hormones and cytokines regulate the key physiological processes of growth and differentiation as well as responses to injury and infection. FIBRODYSPLASIA OSSIFICANS PROGRESSIVA Growth factors and signals are fundamental to many diseases. A single point mutation in the DNA coding for a bone morphogenetic protein is responsible for the development of FOP, a very debilitating disease where muscles are progressively turned into bones. Understanding these mechanisms allowed the selection of a drug, currently used to treat cancer, that may possibly be repurposed to treat FOP.
