“…S100 proteins have been linked to the development of many cancers [ 40 , 46 ], including HCC. Deregulated mRNA expression of many S100 isoforms, i.e., S100P , S100A2 , S100A5 , S100A6 , S100A7 , S100A7A , S100A8 , S100A9 , S100A10 , S100A11 , S100A12 , S100A13 , S100A14 , S100G and S100Z , has indeed been associated with HCC in patients [ 144 ]. In addition, upregulation of several S100 isoforms, i.e., S100P , S100A2 , S100A6 , S100A8 , S100A9 , S100A10 , S100A11 , S100A13 and S100A14 , correlates with poor survival in patients [ 65 , 144 ].…”
