These 8 HCC cell lines consist of 6 metastatic (all with mutant p53) and 2 non-metastatic (with a mutant and a lost p53) ones, being all HBV traceable for relatively close genetic-backgrounds. We have analyzed the related dataset and obtained transcrip- tome (16353 genes) and proteome (7861 proteins) of these 8 HCC cell lines, and explored a group of up-regulated and down-regulated genes [3].展开更多
