AimElucidating differences in gene expression may be useful in understanding the molecular pathogenesis and for developing specific markers for the outcome of hepatitis B virus (HBV) infection. In the present study, expressions of host gene interferon gamma-inducible protein (IP-10), p53, and Foxp3 were studied in hepatocytes of patients with chronic HBV infection to determine a possible link between selected host gene expression and the outcome of HBV infection.Materials and methodsThe study was conducted in 60 patients with chronic HBV infection and they were divided into four groups: HBV-positive cirrhosis (n = 15), HBV-negative cirrhosis (n = 15), HBV-positive hepatocellular carcinoma (HCC) (n = 15) and HBV-negative HCC (n = 15). Total messenger ribonucleic acid (mRNA) extraction was done followed by complementary deoxyribonucleic acid (cDNA) synthesis, and finally gene expression was performed using real-time polymerase chain reaction (PCR) technique.ResultsIP-10 and p53 gene expressions were lower in HBV-positive cirrhosis, and Foxp3 gene expression was upregulated in HBV-positive cirrhosis in comparison to HBV-negative cirrhosis. The expressions of all the three genes were upregulated among HBV-positive HCC in comparison to HBV-negative HCC. The expression of IP-10, p53, and Foxp3 genes was upregulated in HBV-positive HCC in comparison to HBV-positive cirrhosis.ConclusionThis study indicates that there are variations in the expression of the selected genes among cirrhosis and HCC patients with or without HBV. All the three selected genes were more or less upregulated in HBV-positive HCC patients, but only Foxp3 expression was upregulated in HBV-positive cirrhosis. These three particular genes may have a role in the molecular pathogenesis and clinical outcome of HBV-positive cirrhosis and HCC patients. These aspects need further evaluation by studies with larger numbers of cirrhosis and HCC patients.How to cite this articleShahera U, Munshi S, Jahan M, Nessa A, Alam S, Tabassum S.

Interferon-gamma induced protein 10 (IP-10), a chemokine is suggested to be involved in liver injury during Hepatitis B virus infection (HBV). The increase of IP-10 is a critical step for recruitment of inflammatory cells to the local focus of the liver and hepatopathology. This study was designed to assess the correlation of IP-10 gene expression with HBV-DNA and serumAlanine transaminase(ALT) in patients with cirrhosis and HCC.The study was conducted among 60 patients. The study populationwere divided into four groups (15 in each groups)-HBV positive cirrhosis, HBV negative cirrhosis, HBV positiveHCC and HBV negative HCC. Expression of IP-10 gene was observed using real time PCR.IP-10 gene expressions in the above mentioned groups were correlated with serum ALT level and HBV viral load.IP-10 gene was significantly higher in HBV-positive patients with HCC than HBVpositive cirrhosis. Similarly, the expression of IP-10 was significantly higher in HBV-positive HCC than HBVnegative HCC patients. However, the expression of IP-10 was reduced in HBV-positive cirrhosis in comparison with HBV-negative cirrhosis.IP-10 gene expression in liver was not correlated with the serum levels of ALT in any of the study groups. HBV- DNA load also did not correlated with IP-10 gene expression in HBV positive HCC and HBV positive cirrhosis patients.This study shows that there was no significant change with the expression of IP-10 gene in any of the study groups with ALT level or viral load, though differential expression of IP-10 gene were observed in cirrhosis and HCC patients.
