For example, overexpression of C1QTNF6 was found in gastric carcinoma23 (although it has been reported that the C1QTNF6 protein significantly suppresses the proliferation of oral squamous cell carcinoma cells)24; PARP12 upregulation was associated with the inhibition of metastasis in hepatocellular carcinoma cell lines25. Here, PARP12 is linked to oral cavity squamous cell carcinoma.
