Increase of mitochondria mass in cardiomyocytes and decrease of survival time caused by MAP1S depletion suggest an impairment of autophagosomal degradation. A, increased mitochondrial mass in stressed MAP1S-deficient cardiomyocytes is shown. Data are the mean ± S.D. of three pairs of littermates. Significance was determined by Student's t test. B, reduced survival in starved MAP1S-deficient neonates is shown. The indicated significance of difference between survival curves for wild-type and knock-out mice was determined by Kaplan-Meier analysis.
