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. Here, MTUS1 is linked to head and neck squamous cell carcinoma.
