Cardiac hypertrophy is one of adaptive responses of the heart to a variety of pathological stimuli, including hypertension, myocardial infarction, congenital heart disease, heart valvula disease, and perturbations in sarcomeric function due to altered expression or mutations of contractile proteins. Increase in wall tension and hormonal stimuli are thought to directly activate various membrane-bound receptors and signal transduction cascade within cardiomyocytes resulting in the activation of immediate early genes and responsive genes such as c-jun, c-fos, c-myc, egr-1, ANF, BNP. Then the expression of construction proteins such as MLC-1, skeletal α-actin was unregulated.
