Figure 1 Hepatitis B virus S gene integration cluster near the human origin recognition complex subunit 1 gene locus on chromosome 1 (Chr1 1p32. 3). Genome-wide analysis of hepatitis B virus (HBV) integration in 15 HBV-related hepatocellular carcinoma tumor tissues revealed 14 cases with HBV-human integration. Among these, 10 (71.4%) harbored integration events clustered within a 6 Mb region centered around the origin recognition complex subunit 1 gene (indicated by orange dashed box). A representative case showed HBV S gene integration at the origin recognition complex subunit 1 promoter region. ORC1: Origin recognition complex subunit 1; HBV: Hepatitis B virus.
