The qPCR results showed that the mRNA expression of FGFR2 and CEBPB were significantly upregulated in CC samples compared to that in HB, while some other genes from the analysis results had a varied expression level in CC samples vs. HB and the differences did not reach a statistical significance (Fig 2; Table 1). The gene discussed is FGFR2; the disease is cholangiocarcinoma.
