Fig. 1. Expression of let-7c is differentially regulated in both tumor and sera of cholangiocarcinoma patients.
a Expression of let-7c in 13 cholangiocarcinoma and paratumor tissues by RT-qPCR. b Collected data show the expression of let-7c in 13 cholangiocarcinoma and paratumor tissues. c Immunochemistry to evaluate the expression of let-7c in cholangiocarcinoma and paratumor tissues. d The level of let-7c in serum from distant metastatic patients and non-metastatic patients by RT-qPCR. e Collected data show the expression of let-7c in serum from distant metastatic patients and non-metastatic patients. *P < 0.05; N Normal bile duct tissue; T cholangiocarcinoma (tumor group)
