Cells Control Energy Metabolism Via Hedgehog Signalling Pathway

[Northerner]

Cancer, diabetes, and excess body weight have one thing in common: they alter cellular metabolism. 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.
