In this study we applied our new mouse model of cerebral aneurysms to the iNOS gene knockout mice and observed experimental cerebral aneurysms in these animals to elucidate the role of iNOS in the process of cerebral aneurysm formation. iNOS produces large quantities of NO upon stimulation, such as by proinflammatory cytokines (e.g. n = 3 mice per group for Sham; n = 5 mice per group for Burn. Our data suggest that Sirt1 S-nitrosylation may play a role in iNOS-mediated enhanced inflammatory response and apoptotic change, which, in turn, contribute to muscle wasting and supposedly to insulin resistance after burn injury.
