Figure 9.
The mouse myocardial cells, transfected with miR-181c mimic/inhibitor, were intervened with TNF-α and underwent the TEM scan. There were no significant changes in the gross morphology of myocardial cells and the number of mitochondria between groups (A–F, magnification: 4000 × to 30000 × ). The mitochondria showed abnormal appearance such as disorganization, rupture of the double membrane and reduction or vanish of the crista after TNF-α intervention. The severity of mitochondrial damage were for mimic group>control group>inhibitor group (G, magnification: 50000 × ).
