WebFeb 25, 2024 · This leads to clonal expansion of epigenetically altered hepatocytes that resist infection by HBV. These foci of altered hepatocytes also resist death by CTLs and thus can evolve into HCC (Fig. 1). Interestingly, Mason et al. 7 demonstrated the presence of clones of epigenetically altered hepatocytes in patients with IT-CHB. In addition, they ...

WebJan 2, 2024 · On one hand, the clonal expansion of integrated hepatocytes may be a marker of HCC risk. On the other hand, each integration event provides a unique genetic marker for the cells in which it occurred. Thus, this kind of clonal expansion can be tracked by quantitative detection of integrated HBV DNA. In the present study, we investigated it …
