The Src family kinases: distinct functions of c-Src, Yes, and Fyn in the liver
The Src family kinases Yes, Fyn, and c-Src play a pivotal role in regulating diverse liver functions such as bile flow, proteolysis, apoptosis, and proliferation and are regulated by anisoosmotic cell volume changes, death receptor ligands, and bile acids. For example, cell swelling leads to an inte...

| Summary: | The Src family kinases Yes, Fyn, and c-Src play a pivotal role in regulating diverse liver functions such as bile flow, proteolysis, apoptosis, and proliferation and are regulated by anisoosmotic cell volume changes, death receptor ligands, and bile acids. For example, cell swelling leads to an integrin-sensed and focal adhesion kinase-mediated activation of c-Src-triggering choleresis, proteolysis inhibition, regulatory volume decrease via p38MAPK and proliferation via the activation of the epidermal growth factor receptor and extracellular regulated kinases 1 and 2. In contrast, hepatocyte shrinkage generates an almost instantaneous oxidative stress response that triggers the activation of c-Jun N-terminal kinase and the Src family kinases Fyn and Yes. Whereas Fyn activation mediates cholestasis, Yes triggers CD95 activation and apoptosis. This review will discuss the role of Src family kinases in the regulation of liver function with emphasis on their role in osmo-signaling and bile acid signaling. |
