Hepatocellular carcinomas (HCCs) are characterized by frequent somatic genomic copy number alterations (CNAs), with most of them biologically unexplored. Here, we performed integrative analyses combining CNAs with the transcriptomic data to reveal the cis- and trans-effects of CNAs in HCC. We identified recurrent genomic gains of chromosome 8q, which exhibit strong trans-effects and are broadly associated with ribosome biogenesis activity.

Article Synopsis
  • Conducted an integrative omics analysis to identify lncRNAs related to hepatocellular carcinoma (HCC) using mRNA and lncRNA profiles from HCC tissues.
  • Discovered that the lncRNA named PSTAR inhibits HCC cell growth by activating p53, leading to cell cycle arrest.
  • Found that low levels of PSTAR in HCC tissues are linked to worse patient outcomes, particularly in those with wild-type p53, highlighting its potential as a tumor suppressor.

Hepatitis B virus (HBV) infection is a common infectious disease. Here we perform a genome-wide association study (GWAS) among Chinese populations to identify novel genetic loci involved in persistent HBV infection. GWAS scan is performed in 1,251 persistently HBV infected subjects (PIs, cases) and 1,057 spontaneously recovered subjects (SRs, controls), followed by replications in four independent populations totally consisting of 3,905 PIs and 3,356 SRs.

Objective: HJURP (Holliday Junction-Recognizing Protein) plays dual roles in DNA repair and in accurate chromosome segregation during mitosis. We examined whether the single nucleotide polymorphisms (SNPs) of HJURP were associated with the risk of occurrence of hepatocellular carcinoma (HCC) among chronic hepatitis B virus (HBV) carriers from well-known high-risk regions for HCC in China.

Methods: Twenty-four haplotype-tagging SNPs across HJURP were selected from HapMap data using the Haploview software.

Objective: To evaluate the efficacy and safety of wuling Capsule combined with Pinaverium Bromide in treatment of irritable bowel syndrome (IBS).

Methods: Sixty-four IBS patients were randomized into two groups, the treatment group and the control group, 32 in each group. Patients in the treatment group took wuling Capsule (0.

Background And Aims: Steroid resistance presents an administration difficulty in inflammatory bowel disease (IBD). The reason of steroid resistance is still unclear, but cytomegalovirus (CMV) infection may be a potential cause in some IBD patients. We carried out a meta-analysis to investigate the relationship between CMV infection and steroid-resistant IBD.

Aim: To investigate the relationship between Helicobacter pylori infection and inflammatory bowel disease (IBD) in an Asian population.

Methods: The PubMed, EMBASE, and Cochrane Library databases were searched for observational studies published up until June 2014, without language restrictions. Additional references were obtained from reviewed articles.

The aim of the present study was to evaluate the efficacy of ciprofloxacin (cipro) for the treatment of Crohn's disease (CD) through a meta-analysis of randomized controlled trials. The PubMed, Embase and Cochrane Library databases were searched up to May 2014, with no language restrictions, for randomized placebo-controlled trials. Additional references were obtained from the reviewed studies.

Background: The coinhibitory receptor Programmed Death-1 (PD-1) inhibits effector functions of activated T cells and prevents autoimmunity, however, cancer hijack this pathway to escape from immune attack. The costimulatory receptor glucocorticoid-induced TNFR related protein (GITR) is up-regulated on activated T cells and increases their proliferation, activation and cytokine production. We hypothesize that concomitant PD-1 blockade and GITR triggering would synergistically improve the effector functions of tumor-infiltrating T cells and increase the antitumor immunity.

Chymase, a chymotrypsin-like protease, is a non-angiotensin-converting enzyme (ACE) angiotensin II (Ang II)-generating enzyme. The aim of the present study was to investigate whether chymase activity was increased in inflammatory polyps of elderly patients with functional bowel disorder (FBD). This study enrolled 45 elderly patients with FBD and 44 healthy control individuals.

Purpose: Epithelial cellular adhesion molecule (EpCAM) is an attractive immunotherapeutic target to overcome metastasis of a variety of epithelium-oriented cancers. Edrecolomab, one kind of EpCAM monoclonal antibody (Panorex), has been approved for clinical application as postoperative adjuvant therapy in breast and colorectal cancer. However, the role of EpCAM in gastric cancer metastasis remains unclear.

Aim: To evaluate the diagnostic role of serum RASSF1A promoter hypermethylation in gastric and colorectal adenocarcinoma.

Methods: Methylation-specific polymerase chain reaction (MSPCR) was used to examine the promoter methylation status of the serum RASSF1A gene in 47 gastric adenocarcinoma patients, 45 colorectal adenocarcinoma patients, 60 patients with benign gastrointestinal disease (30 with benign gastric disease and 30 with benign colorectal disease), and 30 healthy donor controls. A paired study of RASSF1A promoter methylation status in primary tumor, adjacent normal tissue, and postoperative serum were conducted in 25 gastric and colorectal adenocarcinoma patients who later were underwent surgical therapy.

Hypoxia inducible factor-1alpha (HIF-1alpha) was well correlated with carcinogenesis and tumor progression in many kinds of cancer. In this study, high expression of HIF-1alpha was found in 37 of the 72 (51.39%) tumor specimens, and significantly correlated with venous invasion and lymphonode invasion.
