Tumours formed from THAP10‐expressing cells were significantly smaller than the empty‐vector control (P = 0.0016) or parental counterparts (P = 0.0015) at day 28 post‐cell inoculation (Fig 7A–C), with an average tumour weight of 1.80 g for THAP10‐expressing cells vs. 5.25 g for empty‐vector controls (P = 0.0009, Fig 7D). This evidence concerns the gene THAP10 and neoplasm.
