Integration of hepatitis B virus and alteration of the 1p36 region found in cancerous tissue of primary hepatocellular carcinoma with viral replication evidenced only in noncancerous, cirrhotic tissue
Daniela Simon, Brian I. Carr – 1 November 1995 – We have studied the genetic profile of the host genome and hepatitis B virus (HBV) in HBV‐associated primary hepatocellular carcinoma (HCC). Comparative analyses of HCC cell line Hep 40 and the original biopsy specimens showed the episomal and replicating form of HBV only in the biopsy specimen from nontumor (NT) cirrhotic liver tissue, where a molecular change in the 1p36 region was detected (NT tissue showed a normal 46XY karyotype). In contrast, only integrated HBV was detected in HCC tumor (T) tissue and Hep 40 cells.
