In this study, the expression of the protein-coding genes ring finger protein 135 (RNF135), ephrin-B2 (EFNB2), ring finger protein 125 (RNF125), homeobox-C 4 (HOXC4), actin-binding LIM protein 1 (ABLIM1) and oncostatin M receptor (OSMR) and the long non-coding RNAs (lncRNA) prospero homeobox 1 antisense RNA 1 (PROX1-AS1) and leukemia inhibitory factor receptor antisense RNA 1 (LIFR-AS1) was investigated in hepatocellular carcinoma, cholangiocarcinoma, colorectal liver metastases and pancreatic ductal adenocarcinoma liver metastases. The gene discussed is OSMR; the disease is cholangiocarcinoma.
