Human hepatocellular carcinoma: primary tumor vs.lung metastasis. Homo sapiens

microRNA exprssion profiling of HCC comparing primary tumor with lung metastasis. To explore differentially expressed microRNAs involved in process of HCC metastasis, and identify their biological functions. Overall design: Two-condition experiment, primary tumor specimens vs. lung metastasis specimens. Biological replicates: 3 primary tumor replicates, 3 lung metastatic replicates. One replicate per array.
