Comparison of gene expression profiles between paired primary and metastasis colorectal carcinoma. Homo sapiens

Paired tissues (normal colon, primary colorectal carcinoma, normal liver, liver metastasis of colorectal carcinoma) from 2 colorectal carcinoma patients in Taiwan were processed to generate total RNA, which was subsequently analyzed for gene expression using Affymetrix U133 plus 2.0 arrays. Overall design: Comparison of gene expression profiles between paired normal colon and primary colorectal carcinoma; between primary colorectal carcinoma and liver metastasis colorectal carcinoma
