Fig. 1From: Role of AP-2α and MAPK7 in the regulation of autocrine TGF-β/miR-200b signals to maintain epithelial-mesenchymal transition in cholangiocarcinomamiR-200b is downregulated in CCA patients. a-b The mRNA and protein expression of E-cadherin, TTF-1, fibronectin, and α-SMA was determined in CCA tissues by Q-PCR and western blot. c-d The mRNA expression of TGF-β and miR-200b was determined in CCA tissues by Q-PCR. e The correlation between miR-200b and TGF-β was analyzed; the correlation between miR-200b and EMT markers were analyzed. **p < 0.01, ***p < 0.001, data represent the mean ± SDBack to article page
