MFN2 and head and neck squamous cell carcinoma: As shown in Figure 6A, BAX was sparsely distributed in the cytosol in control HNSCC cells but overlapped with mitochondria in MTUS1/ATIP1-overexpressed cells; MFN2 knockdown decreased the BAX overlapped with mitochondria in MTUS1/ATIP1-overexpressed cells.
