Association Between ACOX1 and NRF1 Gene Expression and Hepatitis B and C Virus Infections and Hepatocellular Carcinoma in Liver Transplant Patients (Shiraz, Iran).

Abstract

Liver transplantation is used to treat both patients with end-stage liver diseases and those with hepatocellular carcinoma; in Iran, these patients are commonly infected with hepatitis B and C viruses. In the present study, for the first time, we investigated the association between ACOX1 and NRF1 gene and protein expression and presence of hepatitis B virus, hepatitis C virus, and hepatocellular carcinoma in liver transplant patients in South-Central Iran. In this cross-sectional study, we included 200 patients who were seen between 2008 and 2017 for liver transplant at the Namazi Hospital, Shiraz University of Medical Sciences (Shiraz, Iran). All patients received liver grafts from brain dead donors. Donors and recipients were unrelated. ABO compatibility blood group analyses for donor-recipient pairs were conducted. Liver transplant recipients were divided into 3 different groups: hepatitis B virus infected, hepatitis C virus infected, and presence of hepatocellular carcinoma. We also had a control group that included 30 healthy individuals. NRF1 and ACOX1 gene expression levels were evaluated using the SYBER green real-time polymerase chain reaction method. NRF1 and ACOX1 protein expression levels were evaluated using enzymelinked immunosorbent analyses. We used SPSS software for statistical analyses (version 19.0). NRF1 gene expression was increased in all 3 liver transplant recipient groups compared with the control group (not significant, P > .05). Furthermore, ACOX1 gene expression was decreased in all patients compared with control (P > .05). However, we found ACOX1 and NRF1 protein expression to be significantly decreased in all 3 liver transplant recipients groups compared with the control group (P < .05). NRF1 and ACOX1 genes and their protein expressions could affect the development of chronic liver disease.
