Background/Aim:
Hepatitis C virus core protein (HCV-C) has been known to play an important role in hepatocarcinogenesis. But, up to now there is no certain evidence in pathomorphology directly supporting this standpoint. In this study, a human hepatocytes model expressing HCV-C was established for investigating the influence of HCV-C on hepatocytes biological properties.
Methods:
The HCV-C expression plasmid, PcDNA3-C, was transfected into Chang-liver cells to establish HCV-C expressing cells. Proliferation rate and variation index of DNA content of these cells were measured by MTT and FCM. The malignant transformation of these cells was observed by electron microscope. Furthermore, these cells were subcutaneous injected into nude mice to observed their tumor genesis.
Results:
Proliferation rate and variation index of DNA content of these cells markedly increased. 10/10 of BALB/c-nu/nu nude mice generated tumors at 3 weeks after subcutaneous inoculation of the HCV-C expressing cells. And, histological structure of the tumors coincided with that of hepatocarcinoma.
Conclusions:
The HCV-C may play a key role in hepatocarcinogenesis resulting from HCV infection.

The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...
