Fig. 8: Schematic figure showing the crucial roles of AIFM2 in the promotion of HCC metastasis.

AIFM2 is frequently overexpressed in HCC, which is probably caused by DNA hypomethylation and downregulation of miR-150-5p. AIFM2 plays a crucial role in the promotion of tumor metastasis by increasing mitochondrial biogenesis and oxidative phosphorylation through activation of NAD+/SIRT1/PGC-1α signaling.
