Sirtuin 1 activation protects against early brain injury after experimental subarachnoid hemorrhage in rats.

ABSTRACT: Increasing evidence indicates that sirtuin 1 (SIRT1) is implicated in a wide range of cellular functions, such as oxidative stress, inflammation and apoptosis. The aim of this study was to investigate the change of SIRT1 in the brain after subarachnoid hemorrhage (SAH) and its role on SAH-induced early brain injury (EBI). In the first set of experiments, rats were randomly divided into sham group and SAH groups at 2, 6, 12, 24, 48 and 72 h. The expression of SIRT1 was evaluated by western blot analysis, immunohistochemistry and immunofluorescence. In another set of experiments, SIRT1-specific inhibitor (sirtinol) and activator (activator 3) were exploited to study the role of SIRT1 in SAH-induced EBI. It showed that the protein level of SIRT1 was markedly elevated at the early stage of SAH
