Biological function and mechanism of circRNA in the occurrence and development of hepatocellular carcinoma

ABSTRACT: In order to study the biological function and regulatory mechanism of circRNA in the occurrence and development of HCC, we collected cancer and adjacent tissues of 5 HCC patients, extracted total RNA and mixed samples of equal quality. RNA-seq was used to obtain the expression profiles of differential circRNA in HCC tissues, and the expression profiles were annotated and analyzed for differential expression.

Human circRNA expression profiling in plasma sample of hepatocellular carcinoma

Project description:Arraystar Human circRNA Microarray is designed for the global profiling of human circRNAs. In this study, we applied a circRNA microarray to screen the potential biomarker for HCC. 20 samples extracted from plasma samples including HCC group before operation, and after operation, CH group and control group. Each group contained five samples.

The circular RNA profiling of 10 paired HCC and matched peritumor tissues

Project description:We collected primary HCC tumor and matched peritumor tissues from 10 HBV-related HCC patients to analyze the circRNA profile and its alteration in HCC through RNA-seq. A total of 92,204 circRNAs were identified in these 20 tissue samples with more than two unique back-spliced reads, of which 42 circRNAs were dysregulated in all HCC tumor tissue samples when compared with matched peritumor tissues (fold change≥2 and p<0.05). As the detailed analysis of circRNA profiles in HCC, our study undoubtedly improved the comprehensiveness of HCC associated circRNA profiles.

Low SLC22A7 expression in noncancerous liver promotes hepatocellular carcinoma occurrence - a prospective study

Project description:Background & Aims: The recurrence determines the postoperative prognosis of patients with hepatocellular carcinoma (HCC). It is unknown whether de novo HCCs derive from the liver with disability of an organic anion transport. This study was designed to elucidate the link between such transporters and the multicentric occurrence (MO) after radical hepatectomy. Results: SLC22A7 expression was the best predictor of metastasis-free survival (MFS) as judged by the GA (Fold, 0.726; P=0.001). High SLC22A7 gene expression in noncancerous tissue prevent HCC occurrence after hepatectomy (Odds Ratio (OR), 0.2; 95%CI, 0.1-0.6; P=0.004). Multivariate analyses of MFS revealed the independent risk factor to be SLC22A7 expression (OR, 0.3; 95%CI, 0.1-1.0, P=0.043). Low SLC22A7 expression caused MO of HCC significantly (log-rank, P=0.001). In the validation study, multivariate analyses of MFS revealed the independent risk factor to be SLC22A7 expression (OR, 0.5; 95%CI, 0.3-0.8; P=0.012). As judged by Gene set-enrichment analysis, SLC22A7 down-regulation associated with mitochondrion (P=0.008; false discovery rate (FDR)=0.199; normalized enrichment score (NES) =1.804), oxidoreductase activity (P=0.006; FDR=0.157; NES=1.854) and fatty acid metabolic process (P=0.021; FDR=0.177; NES=1.723). Sirtuin3 also determined MFS (P= 0.018). Conclusions: These pathways involving SLC22A7 dysfunction may promote the occurrence of HCC. The 49 noncancerous liver tissues of HCC patients within Milan criteria, treated at our institution between January 2004 and August 2008, were examined as a training set by genome-wide gene expression analysis (GA). Cox proportional hazards regression analyses for MO-free survival (MFS) were performed to estimate the risk factors. Using the independent two institutional cohorts of 134 patients between September 2008 and December 2009, a validation study was employed using tissue microarrays.

Expression profiles in circRHOT1-deficient or control HCC cells.

Project description:RNA-sequencing of Human hepatocellular carcinoma (HCC) cells We analyzed two circRNA profiles expressed in human HCC tissues and identified circRHOT1 as a conserved and dramatically upregulated circRNA in HCC tissues. HCC patients displaying high circRHOT1 level possessed poor prognosis. We demonstrated circRHOT1 significantly promoted HCC growth and metastasis. In order to investigate the mechansim of circRHOT1, we constructed circRHOT1-deficient HCC cell lines. Through RNA-sequencing, we sough to identify the key gene regulated by circRHOT1 in HCC.

The expression of circular RNAs in tumor tissues from three non-cirrhotic hepatocellular carcinoma patients and three cirrhotic hepatocellular carcinoma patients

Project description:Six frozen hepatocellular carcinoma (HCC) samples (three without cirrhotic and three with cirrhotic background) were selected to analyze the circRNA expression profile through circRNA-seq. A total of 20334 circRNAs were identified in these tumor tissues, which were widely distributed in all chromosomes. Differential analysis revealed that 393 were significantly dysregulated in non-cirrhotic HCC when compared with cirrhotic HCC tissues (log2(fold change) > 1 and p < 0.05). Our study undoubtedly provide a new insight in investigating the initiation of HCC.
