We investigated insulin-like growth factor II (IGF-II) mRNA in three groups of human liver samples including primary liver cancers, benign liver tumors and cirrhosis; indeed these pathological conditions would allow us to distinguish between different steps in liver carcinogenesis. A 40- to 100-fold increase in IGF-II mRNA was shown in 9/40 of the liver(More)
The definition of the risk of hepatocellular carcinoma (HCC) recurrence after resection represents a central issue to improve the clinical management of patients. In this study we examined the prognostic relevance of infiltrating immune cell subsets in the tumor (TIL) and in nontumorous (NT) liver (LIL), and the expression of immune-related and(More)
Insulin-like growth factor II (IGF-II) is a polypeptide growth factor thought to be involved in fetal tissue development. We previously showed an increased expression of IGF-II mRNA in human primary liver cancer. The present investigation was undertaken to characterize the overexpressed IGF-II transcripts and to determine whether they are translated into(More)
BACKGROUND Quantitative real-time PCR assays, which are more rapid and practical than pp65 antigenemia determination, are progressively becoming the preferred method for monitoring Human Cytomegalovirus (HCMV) reactivation. However, the relationship between HCMV DNA and antigenemia levels is still under investigation. The aim of this study was to analyse(More)
Hepatitis C virus (HCV) carriers with normal aminotransferase levels often show histological chronic hepatitis. This study was undertaken to determine the effect of interferon (IFN) in such patients. Nineteen HCV carriers with normal aminotransferase activities and chronic hepatitis were randomized to receive IFN-alpha2b (3 million units 3 times weekly for(More)
Hepatitis B virus (HBV) DNA integration has been shown to occur frequently in human hepatocellular carcinomas. We have investigated whether common cellular DNA domains might be rearranged, possibly by HBV integration, in human primary liver tumors. Unique cellular DNA sequences adjacent to an HBV integration site were isolated from a patient with hepatitis(More)
Evasion from protective CD8 responses by mutations within immunodominant epitopes represents a potential strategy of HCV persistence. To investigate the pathogenetic relevance of this mechanism, a careful search for immunodominant CD8 epitopes was conducted in six patients with chronic evolution of HCV infection by analyzing their global CD8 response with a(More)
Hepatitis B virus (HBV) reactivation is a potentially fatal complication of chemotherapy in asymptomatic HBV carriers. Prophylactic lamivudine has proven effective for its prevention, but the potential emergence of lamivudine-resistant HBV YMMD mutants, as shown in patients treated for chronic hepatitis, may limit its use. To evaluate the frequency of HBV(More)
The viral genotype may influence the response to interferon (IFN) treatment in chronic hepatitis C virus (HCV) infection. To characterize potential mechanisms responsible for this effect, we assessed whether IFN modulation of HCV-specific T-cell responses differs in patients infected by different genotypes. The T-cell response to HCV core protein was(More)
Sera from 30 women at high risk for infection, one half of which were SEN virus positive (SENV(+)), were collected at delivery to study SENV mother-to child transmission. Thirteen of their babies were positive for at least one SENV strain: one baby was SENV(+) at birth, eight became positive within 6 months from delivery, and four became positive in the(More)
