Title	Western diet triggers cardiac dysfunction in heterozygous Mybpc3-targeted knock-in hypertrophic cardiomyopathy mice
Description	The study investigates the effect of a heterozygous MYBPC3 mutation combined with Western diet feeding on protein expression in a HCM mouse model. Hypertrophic cardiomyopathy (HCM) is the most common inherited genetic heart disease, characterized by asymmetric left ventricular hypertrophy and diastolic dysfunction. It is generally accepted that HCM is caused by mutations in genes encoding sarcomere proteins (e.g. MYBPC3, MYH7). However, not all mutation carriers will develop HCM and, moreover, phenotypical variation in terms of clinical presentation is large. The phenotypical expression of HCM thus requires additional disease modifiers on top of a sarcomere gene mutation. Clinical reports identify obesity and related comorbidities (diabetes, hyperlipidemia, hypertension) as a major factor contributing to disease expression and severity. We aimed to mimic this situation in a HCM mouse model by feeding a Western diet (8 weeks) to mice carrying a heterozygous mutation in MYBPC3. These heterozygous mice are phenotype negative under normal conditions, but developed cardiac dysfunction and hypertrophy upon Western diet feeding. The main goal of this proteomic screening is to identify clusters of proteins and pathways that are down/upregulated specifically in the left ventricle of mice suffering from a mutation and Western diet feeding. Also, we are interested in protein expression differences caused solely by mutation or Western diet. Group 1 are Wild type mice that received normal chow; group 2 are heterozygous mice that received normal chow; group 3 are Wild type mice that received a Western diet; group 4 are heterozygous mice that received a Western diet.
