... integrin-dependent cell volume sensing and signaling integrates into the overall context of insulin signaling. Similarly, sensing of glutamine-induced hepatocyte swelling by integrins feeds into Src-dependent ... release of mediators such as ATP [10,11]. Recent studies have identified the integrin system as one major sensor of hepatocyte swelling [12–14]. Integrin-inhibitory peptid...
