Differential gene expression in adrenal medulla after cardiac pressure overload

ABSTRACT: Transcriptom analysis of microdissect adrenal medulla after 8 weeks of cardiac pressure overload caused by transverse aortic constriction. Comparative transcriptome analysis was determined using the GeneChip Mouse Genome 430 2.0 Array (Affymetrix, Santa Clara, CA, USA). Six microarrays from microdissected adrenal medulla of mice were performed 8 weeks after transverse aortic constriction or sham operation.

Increased activity of the sympathetic system is an important feature contributing to the pathogenesis and progression of chronic heart failure. While the mechanisms and consequences of enhanced norepinephrine release from sympathetic nerves have been intensely studied, the role of the adrenal gland in the development of cardiac hypertrophy and progression of heart failure is less well known. Thus, the aim of the present study was to determine the effect of chronic cardiac pressure overload in mi  ...[more]
