Abstract

The present invention relates to compositions and methods relating to MEK5 and its role in heart disease. This protein has now been identified as a target for therapeutic intervention due to its role molecular events that lead to or contribute to cardiac hypertrophy and/or dilated cardiomyopathy. In particular, inhibition of MEK5 activity will lead to decrease signalling of the pathways and reduce or eliminate the effects on sarcomere assembly, which in turn result or contribute to cardiac dysfunction. Also provided are transgenic animals and methods of screening for inhibitors of MEK5.

Claims (1)

1. A transgenic mouse, the genome of which comprises an exogenous nucleic acid encoding MEK5DD, operably linked to the alpha-myosin heavy chain promoter, wherein said MEK5DD is expressed in the heart cells of said mouse and wherein said mouse exhibits increased heart size, atrial enlargement, ventricular wall thinning, and eccentric hypertrophy, as compared to wild-type mice.
