Gene expression data of human hepatocellular carcinoma (HCC) and Cholangiocarcinoma (CCA) from Thailand Initiative in Genomics and Expression Research for Liver Cancer (TIGER-LC)

We used Affymetrix HTA2.0 microarray profiling to analyze gene expression patterns in tumor and paired non-tumor tissue of HCC and CCA patients. We used microarrays data to identified molecular subgroup of HCC and CCA patients from Thailand For gene expression profiling, tumors and paired non-tumor tissues were profiled separately using Affymetrix Human Transcriptome Array 2.0 according to the manufacturer's protocol. Raw gene expression data were normalized using the Robust Multi-array Average (RMA) method and sketch-quantile normalization method on Affymetrix Expression Console Software Build 1.3.1.187.
