On the other hand, hsa-miR-647, which was found to be overexpressed in PC patients (logFC 1.49), has also been reported as an inhibitor of hepatocellular carcinoma progression by possibly regulating PTPRF [60], as a regulator of glioma progression and invasion by directly regulating HOXA9 [61], and conversely as a tumour promoter in gastric cancer by regulating the TP73 gene [62]. This evidence concerns the gene TP73 and pachyonychia congenita.
