PTTG3P and neoplasm: Metastasis assays showed that potential pulmonary metastases could be detected by CT scanning in the PTTG3P overexpression group (Fig. 6C bottom, red arrows indicate the suspicious tumour masses), whereas tumour masses were not detected in the empty‐vector control group (Fig. 6C top), which was further confirmed by H&E staining (Fig. 6D).
