Background.
Mammalian sterile 20-like kinase 1 (MST1), the key component of the Hippo-YAP pathway, exhibits an important role in the pathophysiological process of various neurological disorders, including ischemic stroke and spinal cord injury.
However, during subarachnoid hemorrhage, the involvement of MST1 in the pathophysiology of early brain injury remains unknown.
Methods.
We employed intravascular filament perforation to establish the subarachnoid hemorrhage (SAH) mouse model.
The MST1 inhibitor XMU-MP-1 was intraperitoneally injected at 1 h after SAH, followed by daily injections.
MST1 in vivo knockdown was performed 3 weeks prior to SAH via intracerebroventricular injection of adeno-associated virus (AAV) packaged with MST1 shRNA.
The SAH grade, behavioral deficits, TUNEL staining, Evans blue dye extravasation and fluorescence, brain water content, protein and cytokine expressions by Western blotting, immunofluorescence, and proteome cytokine array were evaluated.
Results.
Following SAH, the phosphorylation level of MST1 was upregulated at 12 h, with a peak at 72 h after SAH.
It was colocalized with the microglial marker Iba1.
Both XMU-MP-1 and MST1 shRNA alleviated the neurological deficits, blood-brain barrier (BBB) disruption, brain edema, neuroinflammation, and white matter injury, which were induced by SAH in association with nuclear factor- (NF-) κB p65 and matrix metallopeptidase-9 (MMP-9) activation and downregulated endothelial junction protein expression.
Conclusions.
The current findings indicate that MST1 participates in SAH-induced BBB disruption and white matter fiber damage via the downstream NF-κB-MMP-9 signaling pathway.
Therefore, MST1 antagonists may serve as a novel therapeutic target to prevent early brain injury in SAH patients.
