Immunohistochemical staining was performed on 5-μm sections of paraformaldehyde- fixed, paraffin-embedded tumor samples, adjacent nontumoral liver tissue, normal liver tissue and mouse lung tissue. The details of the immunohistochemistry were described previously [28 (link)]. The slides were incubated with mouse anti-SIRT1 (Abcam), rabbit anti-TFAM (Abcam), rabbit anti-COXIV (Cell Signaling Technology, Danvers, MA, USA) and rabbit anti-TOMM20 (Abcam) primary antibodies. The mouse lung tissue sections (5-μm thick) were stained with hematoxylin and eosin (H&E) so that tumor nodules could be observed. The slides were evaluated under a light microscope (Leica, DM6000M).
