Upregulation of arylsulfatase B in carotid atherosclerosis is associated with symptoms of cerebral embolization

Abstract The aim of this study was to identify genes for which the expression within carotid atherosclerosis was reproducibly associated with the symptoms of cerebral embolization. Two publically available microarray datasets E-MEXP-2257 and GSE21545 were analysed using GeneSpring 11.5. The two data...

Two publically available microarray datasets E-MEXP-2257 and GSE21545 were analysed using GeneSpring 11.5.

Only 7 differentially expressed genes or 0.4% (7/1,752) were consistent between the datasets.

In vitro incubation of VSMCs with the ARSB inhibitor L-ascorbic acid resulted in marked upregulation of SIRT1 and AMPK.
