TUSC3 resides on chromosome 8p which is frequently deleted in advanced stage tumors. Here, the authors show that TUSC3 loss mediated by miR-224/-520c promotes NSCLC metastasis where it enhances ATF-6α-dependent UPR and HRD-1 dependent ERAD, which in turn suppress p53-NM23H1/2 tumor suppressor pathway.
