Endothelin-1 Induced Middle Cerebral Artery Occlusion Model for Ischemic Stroke with Laser Doppler Flowmetry Guidance in Rat

Saeed Ansari¹, Hassan Azari², Kenneth J. Caldwell¹, Robert W. Regenhardt³, Vishnumurthy S. Hedna⁴, Micheal F. Waters⁴, Brian L. Hoh¹, Adam P. Mecca³

¹Department of Neurosurgery, University of Florida , ²Department of Anatomical Sciences, Shiraz University of Medical Sciences, Shiraz, Iran , ³Department of Physiology and Functional Genomics, University of Florida , ⁴Department of Neurology, University of Florida

Several animal models of cerebral ischemia have been developed to simulate the human condition of stroke. This protocol describes the endothelin-1 (ET-1) induced middle cerebral artery occlusion (MCAO) model for ischemic stroke in rats. In addition, important considerations, advantages, and shortcomings of this model are discussed.

Utilizing a Cranial Window to Visualize the Middle Cerebral Artery During Endothelin-1 Induced Middle Cerebral Artery Occlusion

Robert W. Regenhardt¹, Saeed Ansari², Hassan Azari³, Kenneth J. Caldwell², Adam P. Mecca¹

¹Department of Physiology and Functional Genomics, University of Florida , ²Department of Neurosurgery, McKnight Brain Institute, University of Florida , ³Department of Anatomical Sciences, Shiraz University of Medical Sciences, Shiraz, Iran

This article describes a method for visualizing rat cerebral arteries through a cranial window using temporal craniectomy in order to view proximal portions of the middle cerebral artery (Figure 1). This versatile method can be combined with various techniques of drug delivery to measure cerebral artery reactivity in vivo.

Here we describe a protocol to investigate the prenylation and guanosine-5'-triphosphate (GTP)-loading of Rho GTPase. This protocol consists of two detailed methods, namely membrane fractionation and a GTPase-linked immunosorbent assay. The protocol can be used for measuring the prenylation and GTP loading of different other small GTPases.
