Introduction

Hepatitis C virus is associated with diverse liver diseases including acute and chronic hepatitis, steatosis, cirrhosis and hepatocellular carcinoma. Several studies have explored viral mechanisms involved in the establishment of persistent infection and oncogenic Hepatitis C virus. Expression assays of Hepatitis C virus core protein suggest that this protein has transforming and carcinogenic properties with multifunctional activities in host cells. Characterization of expressed genes in cells expressing Core protein is important in order to identify candidate genes responsible for these pathogenic alterations.

Objective

To compare and identify gene expression profiles in the human hepatocarcinoma derived cell line, HepG2, with transient expression of Hepatitis C virus Core protein.

Materials and methods

We have used comparative PCR-mediated differential display of mRNA from HepG2 hepatocarcinoma with and without transient expression of HCV Core protein or green fluorescent protein, previously obtained using the Semliki Forest Virus-based expression, through transduction of recombinant particles, rSFV-Core and rSFV-GFP, respectively.

Results

We observed differences in band intensities of mRNA in HepG2 cells transduced with rSFV-Core compared with those detected in cells without transduction, and transduced with rSFV-GFP. Cloning and sequencing of a gene fragment (258 bp) that was expressed differentially in HepG2 cells transduced with rSFV-Core, was identified as selenocystein lyase.

Conclusion

The results confirm that HCV Core protein expressed in HepG2 is associated with specific changes in mRNA expression, including the gene for selenocystein lyase. This gene may be involved in the pathophysiology of hepatocellular carcinoma."xsd:string
