Data source for bio-informatics analysis
A total of 488 mRNA expression profiles for patients with HCC were downloaded from Gene Expression Omnibus (GEO; accession number GSE14520), which were detected using a single-channel platform (Affymatrix Genechip HG-U133A 2.0 arrays) (14). All of the patients had transcriptomic data form the tumor and peri-tumor samples.
