Tafazzin knockdown induces hypertrophy in neonatal myocytes in vitro; hypothesis-generating for Barth syndrome mechanisms and should not yet change practice.
Does tafazzin knockdown cause hypertrophy in neonatal ventricular myocytes?
Decreased tafazzin expression causes cardiomyocyte hypertrophy in vitro, providing mechanistic insight into dilated cardiomyopathy in Barth syndrome.
Quan He (2010) studied Cardiomyocyte hypertrophy / Barth syndrome. Tafazzin small hairpin RNA (shRNA) adenovirus vs. Scrambled shRNA controls was evaluated on Cardiomyocyte hypertrophy (surface area, protein synthesis, and brain natriuretic peptide expression). Tafazzin knockdown using shRNA adenovirus in neonatal ventricular myocytes significantly increased cell surface area, protein synthesis, and brain natriuretic peptide expression, causing hypertrophy.
