(Submitter supplied) Background: Hepatocellular carcinoma (HCC) is increasing in incidence and treatment is often unsuccessful. Thus, prevention in high-risk patients with established cirrhosis has been proposed as an alternative strategy. It has been suggested that the increased inflammation and fibrogenesis observed during cirrhosis predisposes the liver to future malignant transformation to HCC through a “field effect”. more...

(Submitter supplied) Background & Aims: Cirrhosis and chronic inflammation precede development of hepatocellular carcinoma (HCC) in approximately 80% of cases. We investigated immune-related gene expression patterns in liver tissues surrounding early-stage HCCs and chemopreventive agents that might alter these patterns to prevent liver tumorigenesis. Methods: We analyzed gene expression profiles of non-tumor liver tissues from 392 patients with early-stage HCC (training set, n=167 and validation set, n=225) and liver tissue from patients with cirrhosis without HCC (n=216, controls) to identify changes in expression of genes that regulate the immune response that could contribute to hepatocarcinogenesis. more...

(Submitter supplied) BACKGROUND & AIMS: Cirrhosis affects 1% to 2% of the world population and is the major risk factor for hepatocellular carcinoma (HCC). Hepatitis C cirrhosis-related HCC is the most rapidly increasing cause of cancer death in the United States. Noninvasive methods have been developed to identify patients with asymptomatic early-stage cirrhosis, increasing the burden of HCC surveillance, but biomarkers are needed to identify patients with cirrhosis who are most in need of surveillance. more...

(Submitter supplied) Background: It is a challenge to identify those patients who, after undergoing potentially curative treatments for hepatocellular carcinoma, are at greatest risk of recurrence. Such high-risk patients could receive novel interventional measures. An obstacle to the development of genome-based predictors of outcome in patients with hepatocellular carcinoma has been the lack of a means to carry out genomewide expression profiling of fixed, as opposed to frozen, tissues. more...

(Submitter supplied) Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare transcriptome profiling (RNA-seq) between treatment and control model samples. Results: Using the RNA-seq analysis workflow, we mapped about an average of 80 million sequence reads per sample to the rat genome (Rnor_6.0) and identified 34,194 transcripts. more...

(Submitter supplied) Hepatocellular carcinoma (HCC) is one of the leading cause of cancer-related mortality worldwide. Liver cirrhosis is well-established risk factor of HCC development, although prevention of HCC in cirrhosis patients is challenging. By utilizing bioinformatic compound screening based on a clinical HCC-risk-predicitve gene signature, we identified captopril as a potential HCC chemoprevention agent. We tested the drug in rats with diethylnitrosamine (DEN)-induced cirrhosis and HCC, and confirmed its HCC-preventive effect.
