(A) Apoptosis assays were conducted by labeling the deoxyribonucleic acid with 5-bromo-2′-deoxyuridine 5′-triphosphate) in heart and liver tissue from the affected patient (family 600, II-16) and control heart samples. A positive control was created by adding 1 μg/μl deoxyribonucleic acids. Apoptotic cells were detected as brown dots. No signs of apoptosis were detected in all tested tissue. (B) Terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling staining of fibroblasts and flow cytometry from patient and Ctrl1 and Ctrl3. The histograms of the fluorescein signal collected by using the terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling method are shown. There is no difference in the apoptotic signals between the 2 control subjects and patient cells. (C) Western blot analysis of apoptotic markers (annexin V, caspase 3 [2 subunits: 17 and 19 KD]) in patient and control fibroblasts on the left panel. GAPDH was used as loading control. Quantification of apoptotic markers by densitometry does not show a significant difference in expression levels (n = 3 experiments with each 2 to 3 replicates). Abbreviations as in Figures 2, 3, and 4.
