Abstract: Hepatitis C virus is responsible for liver damage and various metabolic disorders. HCV infections promote oxidative stress and cause damage to macromolecules. The aim of our study was to design a preliminary study with establishment of HCV genotype 3a infectivity assay in order to determine DNA damage in Huh-7 cell line at 72 hours post inoculation. Quantitative expression levels of COX-2 and GSR (oxidants and antioxidants), DNAPKCs, ATM, ATR and PARP (DNA damage and repair genes), RB and P53 (tumor suppressor genes) and VEGF (angiogenesis marker) were observed via real time PCR. Our findings revealed 1.533 fold upregulated expression of COX-2. The expression level of GSR was increased by1.27 fold and VEGF expression decreased by 0.367 fold. Thus, preventing cells to enter cancerous phase.
