NDUFA7 and cardiac hypertrophy: We further provide several lines of evidence showing the important role of ndufa7 in cardiac hypertrophy: Knockdown of ndufa7 leads to cardiac defect in developing zebrafish embryos; ndufa7 depletion contributes to the elevated expression of hypertrophic biomarkers nppb and nppa; calcineurin signalling is involved in ndufa7 inhibition induced cardiac hypertrophy.
