| pubmed-article:15240405 | pubmed:abstractText | We studied the effect of treatment with the Angiotensin II AT(1) receptor antagonist candesartan (0.3 mg/kg/day via osmotic minipumps for 4 weeks compared with administration of vehicle) in brain microvessels in adult spontaneously hypertensive rats (SHR) that were vulnerable to stroke and normotensive control rats (WKY). At the dose administered, candesartan normalized blood pressure in SHR without significantly affecting blood pressure in WKY rats. We performed the gene expression analysis in rat brain microvessels using the Affymetrix Gene Chip Expression Analysis Technique. From a total of 8,799 probe array sets analyzed, we found abundant abnormalities in gene expression in SHR. Because stress has been suggested as a precipitant factor in brain ischemia and treatment with AT(1) receptor antagonist candesartan prevents the hormonal and sympathoadrenal reaction to isolation stress and protects from stress-induced gastric ulcers, we focused on the expression of stress-related genes. We found a higher number of probe array sets modified by candesartan treatment in normotensive WKY rats than in hypertensive SHR. AT(1) receptor blockade decreased the transcription levels of the stress-related tyrosine kinase receptor, stathmin, and fibroblast growth receptor genes in WKY and SHR rats. Our results indicate that Angiotensin II and its AT(1) receptors can influence gene expression independently of the effects on blood pressure. In addition, AT(1) receptor regulation of stress-related genes in brain microvessels may explain the proposed association between stress and ischemic disorders of the brain. | lld:pubmed |
