Research Abstract

We evaluated the role of a transcription factor, SREBP-1, in the development of hypertesive heart disease. We continuously administrated the vasocontractile agent angiotensin II (Ang II) to the SREBP-1-knockout (KO) mice and wild type mice. The wild mice showed the marked fibrous changes around the coronary vasculature in the heart, whereas KO showed the slight changes. We analyzed the alteration of cardiac gene expression by DNA microarray system and confirmed by real-time RT-PCR. The gene groups for extracellular matrix and inflammatory chemokine and cytokine were significantly changed in the wild mice; however, those were suppressed in the KO mice. These findings suggest that SREBP-1 is involved in the development of fibrous changes seen in the hypertensive heart disease.
