VCAM1 and hepatitis A virus infection: Among the 75 unique probes, 7 showed statistically significant differential expression between HCC (n = 49) and hepatitis (HBV or HCV; n = 18) groups: AFP, beta-catenin (CTNNB), and colony stimulating factor-1 (CSF1) were up-regulated in HCC; L-Selectin (SELL), insulin growth factor binding protein-6 (IGFBP6), interleukin 6 receptor (IL6R), and vascular cell adhesion molecule 1 (VCAM1) were very slightly down-regulated in HCC (p < 0.05) (Table 4, Fig. 2).
