Researchers converted bad fat to good fat

brown-adipocytes-in-white-adipose

Scientists from ETH Zurich have shown for the first time that brown and white fat cells in a living organism can be converted from one cell type to the other. Their work, using mice as a model organism, provides important new insights into the origin of brown fat cells, which is a prerequisite for the development of successful anti-obesity therapies. Two More...

The binding of Sonig Hedgehog (Shh) to its receptor Patched (Ptch) causes the activation of Smo. In the previously known canonical pathways Smo in turn regulates gene expression via Gli transcription factors. In the newly discovered pathway, the activation triggers the influx of calcium and leads to the activation of various calcium-dependent enzymes, such as the calmodulin kinase (Camkk2), AMP-activated kinase (Ampk) and liver kinase B1 (Lkb1). This signalling pathway can also be specifically activated by agents such as cylcopamine. Both signal pathways change the metabolisms of muscle and brown fat cells, enabling them to rapidly absorb and utilise large quantities of glucose.
