Flow diagram of analyses and associated miRNAs found to be dysregulated. A final qPCR verification step was also completed to confirm the magnitude and expression levels determined by microarray but not described herein [1]. A Venn diagram [8] highlights overlapping miRNAs identified in analysis three and analysis four, yielding seven overlapping miRNAs. Abbreviations are as follows: Intrahepatic cholangiocarcinoma tumor tissue (CTT); distal non-tumor tissue (D-NT); and normal non-tumor tissue (N-NT).
