Hypothesis-generating for thin-filament cooperativity in hypertrophic cardiomyopathy; leaves open validation before any mechanistic or therapeutic translation.
Explores experimental and analytical approaches to broaden the understanding of cooperative regulation of cardiac contraction and the impact of cardiomyopathy mutations.
Loong et al. (2012) conducted a review in Familial hypertrophic cardiomyopathy. Tropomyosin mutations vs. Wild-type tropomyosin was evaluated. Reduced tropomyosin rigidity associated with familial hypertrophic cardiomyopathy mutations is hypothesized to alter cooperative calcium-induced activation of cardiac thin filaments.
