Sirt3 deficiency impairs neurovascular recovery in ischemic stroke.

ABSTRACT:

Aims

Sirt3 is one member of the NAD⁺ -dependent protein deacetylase family and plays crucial roles in diverse aspects of mammalian biological function. Then the role of Sirt3 on ischemia stroke is unknown.

Methods

To examine the effect of Sirt3 on ischemic stroke, we performed transient middle cerebral artery occlusion (tMCAO) in adult male Sirt3 knockout (KO) and wild-type (WT) mice.

Results

The level of Sirt3 in infarct region is decreased after ischemic stroke. In addition, we found that Sirt3 KO mice showed worse neurobehavioral outcome compared with WT mice, accompanied by decreased neurogenesis and angiogenesis as shown by the reduction in number of DCX⁺ /BrdU⁺ cells, NeuN⁺ /BrdU⁺ cells, and CD31⁺
