The further analysis showed that a total of 121 genes were included in the 13 OAMs; according to the expression levels of the 121 genes in the microarray data, a total of 7 differentially expressed genes were identified between any two groups, including cyp2b6 (CHB vs. HCC groups), pi3 (cirrhosis vs. HCC groups), and mmp2, pi3, ptk2, timp2, tnfrsf10b (CHB vs. cirrhosis groups). Here, TNFRSF10B is linked to Cirrhosis.
