S1 Table summarizes the age, gender, diagnosis, fibrosis and inflammation scores for the subjects. The number of subjects with grade 3 or 4 fibrosis were equal in the HCV and the non-HCV liver tissues (n = 3). PTPRE levels were significantly lower in tissue obtained from HCV-infected humans compared to liver tissues from people with liver disease other than HCV infection when normalized to GAPDH (Fig 6A and 6B), and PTPRE levels did not correlate with inflammation or fibrosis score (Fibrosis data shown in S1 Fig). The gene discussed is PTPRE; the disease is fibrosis.
