In contrast, two down-regulated genes in OVCAR-3 and OAW-42 cells, the USP12 and PTK2, reported to promote tumor cell growth, both exhibited a weak positive correlation with an adverse OS, (HR = 1.17, p = 0.018) and (HR = 1.18, p = 0.016), respectively. This evidence concerns the gene PTK2 and neoplasm.
