Early oesophageal carcinoma with a defect of the oesophageal muscularis propria: a rare case report.

We herein report a rare case of early oesophageal cancer combined with an oesophageal muscularis propria defect discovered under endoscopic submucosal dissection. The surgeon did not damage the muscularis propria during endoscopic resection; however, we observed the mediastinal cavity as well as the later occurrence of subcutaneous emphysema. Consequently, the patient was considered to have a muscularis propria defect.

Identification of gene-specific DNA methylation signature for Colorectal Cancer.

Background: Colorectal Cancer (CC), a common disease causing approximately million deaths annually, has been the third most frequent type of malignancy. We aimed to identify gene-specific DNA methylation signature to function as prognostic and predictive markers for CC patient survival.

Methods: Expression profiles of gene-specific DNA methylation and the corresponding clinical information of 201 CC patients were downloaded from The Cancer Genome Atlas (TCGA) dataset and differentially expressed gene-specific DNA methylation was identified after tumor subtype classification.

Eph/ephrin signalling serves a bidirectional role in lipopolysaccharide‑induced intestinal injury.

A growing body of evidence has demonstrated that Eph/ephrin signalling may serve a central role in intestinal diseases. However, whether erythropoietin‑producing hepatocellular (Eph)/ephrin signalling is associated with the development of post‑infectious irritable bowel syndrome (PI‑IBS) is still unknown. In the present study, the role of Eph/Ephrin signalling in lipopolysaccharide (LPS)‑induced intestinal injury was evaluated in vivo and in vitro.

A Novel EphA2 Inhibitor Exerts Beneficial Effects in PI-IBS and Models via Nrf2 and NF-κB Signaling Pathways.

Though the detailed pathological mechanism of post-infectious irritable bowel syndrome (PI-IBS) remains unclear, accumulating evidence indicates that oxidative stress and inflammation are implicated in the process of PI-IBS. Oxidative stress and inflammation are regulated by Nrf2 and NF-κB signaling pathways, respectively. EphA2, a member of Eph receptor family, promotes oxidative stress and inflammatory responses via regulation of Nrf2 and NF-κB signaling pathways in various types of human diseases.
