Scientists from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and the Medical University of Vienna together with an international research team have jointly resolved a new molecular circuit controlling cellular metabolism. The previously unknown signalling pathway, acting downstream of the hedgehog protein enables muscle cells and brown fat cells to absorb sugars without relying on insulin. Substances that selectively activate the signalling pathway could thus be utilized in the treatment of diabetes and obesity. With their results, the researchers are also able to explain why various new anti-cancer agents have induced mysterious pronounced side effects in the clinics.
Hedgehog was initially identified as an important protein for embryonic development across various organisms.
"Agents that only activate the Smo-calcium/AMP-kinase hedgehog signalling pathway are therefore candidates as medications for treating excess body weight, as well as type-1 and type-2 diabetes.
