To simulate complex processes in the liver mathematically, the scientists chose three phenomena each they could transform in a model: The liver
regeneration after injury by cuts, the defense of the liver cells against infections and finally the further development of a fatty liver to liver
cancer. In a fatty liver (hepatic steatosis) larger accumulations of fat can be found which represent normally a benign phenomenon.
However, it can also trigger an inflammatory response that leads in the most likely cases to a liver of cirrhosis
(Pathological change of liver tissue) ending in liver cancer.
Goal was to interrupt this process and to find a point on which it would be possible to intervene. Prof. Gebhardt found this point in the so-called
Hedgehog signaling pathway. This pathway controls the embryonic cell growth. If the signal pathway is interrupted in the liver, the rhythm of the
cell processes changes resulting in a fatty liver. "It is a gearwheel that combines the rhythm of the work cell with steatosis and metabolism"
explains Gebhardt in a recent press release.
