Adrenomedullin was originally isolated from pheochromocytoma cells and reduces insulin resistance by decreasing oxidative stress.
White matter lesions induced by aging and hyperglycemia play a crucial role in cognitive impairment in poststroke patients.
Here, we examine whether adrenomedullin deficiency and aging exacerbate ischemic white matter injury after prolonged cerebral hypoperfusion.
Adrenomedullin heterozygous, wild-type young/aged mice were subjected to prolonged hypoperfusion.
Prolonged cerebral hypoperfusion followed by immunohistochemical analysis was used to evaluate white matter injury.
After prolonged hypoperfusion, white matter damage progressed in a time-dependent manner in AM+/− group compared with the wild-type group.
The number of oligodendrocyte progenitor cells gradually increased after prolonged hypoperfusion, whereas oligodendrocytes decreased following a transient increase, but the ratio of increase was mild in the AM+/− group (P<0.05).
Oxidative stress was detected in oligodendrocytes, with a larger increase in the AM+/− group (P<0.05).
Aged mice showed the same tendency, but white matter damage was worse, especially in the aged AM+/− group.
Our results demonstrated that white matter injury was increased in adrenomedullin deficiency, which induced oxidative stress.
White matter injury was more exacerbated because of hyperglycemia in aged AM+/− group.
Adrenomedullin may be an important target in the control of ischemic white matter injury.
