These cases were divided into two groups: group 1 (HCC; n = 35), samples were collected from patients diagnosed and treated at the National Cancer Institute, Cairo University, between December 2005 and August 2008; group 2 (CH; n = 34), samples were collected from HCV associated chronic hepatitis (CH) patients admitted to Kasr Al-Aini School of Medicine, Cairo University, in the same period

and enrolled in routine diagnosis or therapeutic procedures. The mean age of CH patients was 47.5 years and M:F ratio was 1.5:1, whereas the mean age of HCC was 51.6 years and M:F ratio was 1.3:1. All cases of CH were graded and staged according to the modified Knodell scoring system [23] and all HCC selleck chemicals cases were graded according to the World Health Organization (WHO) classification criteria and staged according to the American Joint Pritelivir committee on Cancer [24]. The percent of normal to tumor ratio were more than 80% in all studied cases to overcome the nominalization effect of the tumor stroma and/or necrosis as well as the cirrhotic tissues factors in the studied specimens. Table 1 illustrates the clinico-pathological features of the studied cases. Normal liver tissue samples this website were obtained from liver transplant donors (15 samples) and were used as controls. A written consent was obtained from

all patients and normal liver donors prior to enrollment in the study and the ethical committee of NCI approved the protocol, which was in accordance with the ethical guidelines of the 1975 Declaration of Helsinki.

HepG2 cell culture HepG2 cells were used to establish the in vitro HCV replication. HepG2 culturing and infection were carried out according to previous protocols [25]. Briefly, HepG2 cells were maintained in 75 cm culture flasks (Greiner bio-one GmbH, Germany) containing Dulbecco’s Modified Eagle’s Medium (DMEM) supplemented with 4.
