Diagnosis of Inverted Meckel's diverticulum by double-balloon enteroscopy: a case report.

Background: Meckel's diverticulum (MD) is the most common congenital defect of the gastrointestinal tract, occurring in about 1% to 2% of population. Most MD are rarely symptomatic, with presenting symptoms including diverticulitis, digestive tract hemorrhage and intestinal obstruction. The semblance of symptoms to enteritis and appendicitis makes preoperative diagnosis challenging.

iTRAQ-Based Proteomics Screen identifies LIPOCALIN-2 (LCN-2) as a potential biomarker for colonic lateral-spreading tumors.

The improvement and implementation of a colonoscopy technique has led to increased detection of laterally spreading tumors (LSTs), which are presumed to constitute an aggressive type of colonic neoplasm. Early diagnosis and treatment of LSTs is clinically challenging. To overcome this problem, we employed iTRAQ to identify LST-specific protein biomarkers potentially involved in LST progression.

Decreased expression of PBLD correlates with poor prognosis and functions as a tumor suppressor in human hepatocellular carcinoma.

Recent accumulating genomic and proteomic data suggested that decreased expression of phenazine biosynthesis-like domain-containing protein (PBLD) was frequently involved in hepatocellular carcinoma (HCC). However, there is lack of systematical investigation focusing on its expression pattern, clinical relevance, and biological function. Here, we found that PBLD was frequently decreased in HCC tissues relative to adjacent non-tumorigenic liver tissues.

Endoscopic submucosal dissection for the treatment of rectal carcinoid tumors 7-16 mm in diameter.

Objective: Small rectal carcinoid tumors (<10 mm) are often removed via endoscopic submucosal dissection (ESD). However, the use of ESD for tumors of an intermediate size (7-16 mm) is less well documented. This study aimed to evaluate the efficacy and safety of ESD compared with endoscopic mucosal resection using a cap (EMR-C) for the treatment of 7-16-mm rectal carcinoids.

Interleukin-11 induces the expression of matrix metalloproteinase 13 in gastric cancer SCH cells partly via the PI3K-AKT and JAK-STAT3 pathways.

Interleukin (IL)-11 is expressed in the majority of gastric carcinomas and has been associated with an aggressive phenotype and poor prognosis of gastric adenocarcinoma. Matrix metalloproteinase (MMP)-13 has been detected in numerous invasive malignant tumor types and exhibits a broad spectrum of activities on connective tissue components. In this study, we investigated whether IL-11 affects the expression of MMP-13 in human gastric cancer cells, as well as the underlying mechanism.

ZNF703 acts as an oncogene that promotes progression in gastric cancer.

ZNF703, a member of the NET/Nlz family of zinc finger transcription factors, contributes to aspects of developmental growth and patterning across evolutionarily diverse species. ZNF703 has been identified as a novel oncogene in human breast cancer. In the present study, we investigated the expression of ZNF703 in gastric carcinoma and attempted to determine, using cell line models, its biological actions.
