Moreover, Western blotting and qRT-PCR experiments were performed on nine pairs of matched CCA normal and tumor tissues and indicated that the protein and mRNA expression levels of GOLGA7B were significantly higher in tumor tissues than in normal tissues (Figure 3F, G) and that the lncRNA AGAP2−AS1 was substantially expressed at lower levels in normal tissues than in tumor tissues (Figure 3F). This evidence concerns the gene GOLGA7B and cholangiocarcinoma.
