PADI4 facilitates stem-like properties and cisplatin resistance through upregulating PRMT2/IDs family in oesophageal squamous cell carcinoma.

Background: Oesophageal squamous cell carcinoma (OSCC) is a highly lethal cancer characterized by its aggressive nature and chemotherapy resistance. Peptidylarginine deiminase 4 (PADI4) regulates protein citrullination and is associated with various cancer developments. The role of PADI4 in OSCC progression and chemoresistance remains unexplored.

Alcohol accelerates the development of esophageal squamous cell carcinoma through elevated Gram-negative bacteria in peripheral circulation.

Alcohol consumption is intricately linked to the incidence of esophageal squamous cell carcinoma (ESCC). This study comprehensively investigates the role of alcohol-induced microbial alterations in ESCC progression. A retrospective analysis of 328 patients demonstrated that alcohol consumption markedly increases the risk of ESCC and boosts the expression of the proliferation marker Ki67.

A retrospective analysis of 26 cases of duodenal neuroendocrine tumor treated by endoscopic submucosal dissection.

Background: Duodenal neuroendocrine tumors (D-NETs) are rare but clinically significant tumors that can occur in various parts of the duodenum, including the duodenal papilla. Endoscopic submucosal dissection (ESD) has emerged as a minimally invasive treatment option for D-NETs, offering potential advantages in terms of tumor removal and postoperative recovery. We aimed to retrospectively analyze the clinical characteristics and prognosis of ESD for D-NETs.

Short-term endoscopic alterations of early gastric cancer after successful eradication of Helicobacter pylori.

Background: Detecting and demarcating early gastric cancers (EGC) after eradication therapy of Helicobacter pylori (H. pylori) is a challenging task due to the fact that the lesion's surface is covered with gastritis-like tissue (non-neoplastic epithelium covering the cancerous tissue). However, our study aimed to investigate the endoscopic alterations of EGC within 3 months after eradication, which has not been reported clearly yet.

Free-Hand Endoscopic Full-Thickness Resection for Duodenal Subepithelial Lesions.

Background And Aim: This work aims to evaluate the efficacy and safety of free-hand endoscopic full-thickness resection (EFTR) for duodenal subepithelial lesions (SELs).

Methods: We performed a retrospective review of 105 patients with duodenal SELs who underwent free-hand EFTR. Free-hand EFTR means no other devices (over-the-scope clip or full-thickness resection device) are required.

FOXC1-mediated serine metabolism reprogramming enhances colorectal cancer growth and 5-FU resistance under serine restriction.

Colorectal cancer (CRC) is the most common gastrointestinal malignancy, and 5-Fluorouracil (5-FU) is the principal chemotherapeutic drug used for its treatment. However, 5-FU resistance remains a significant challenge. Under stress conditions, tumor metabolic reprogramming influences 5-FU resistance.

Endoscopic resection for esophageal gastrointestinal stromal tumors: a multi-center feasibility study.

Background: Esophageal gastrointestinal stromal tumors (E-GISTs) are highly uncommon and have not been thoroughly examined.

Objectives: The objective of this multi-center study was to assess the viability of endoscopic resection (ER) in the treatment of E-GISTs and to explore its clinical implications.

Design: This was a multi-center retrospective study.

Alcohol inducing macrophage M2b polarization in colitis by modulating the TRPV1-MAPK/NF-κB pathways.

Background: Macrophages exhibit different phenotypes in inflammatory bowel disease (IBD) and promote inflammation or tissue repair depending on their polarization state. Alcohol is a widely used solvent in pharmaceutical formulations, and its consumption is associated with an increased risk of colitis; however, its effects on macrophages in IBD remain poorly understood.

Purpose: This study aimed to investigate the effect of alcohol on macrophages in dextran sodium sulfate (DSS)-induced colitis and understand the underlying mechanisms.

STK3 kinase activation inhibits tumor proliferation through FOXO1-TP53INP1/P21 pathway in esophageal squamous cell carcinoma.

Purpose: Esophageal squamous cell carcinoma (ESCC) is an aggressive disease with a poor prognosis, caused by the inactivation of critical cell growth regulators that lead to uncontrolled proliferation and increased malignancy. Although Serine/Threonine Kinase 3 (STK3), also known as Mammalian STE20-like protein kinase 2 (MST2), is a highly conserved kinase of the Hippo pathway, plays a critical role in immunomodulation, organ development, cellular differentiation, and cancer suppression, its phenotype and function in ESCC require further investigation. In this study, we report for the first time on the role of STK3 kinase and its activation condition in ESCC, as well as the mechanism and mediators of kinase activation.

IGF-1-mediated FOXC1 overexpression induces stem-like properties through upregulating CBX7 and IGF-1R in esophageal squamous cell carcinoma.

Substantial evidence attests to the pivotal role of cancer stem cells (CSC) in both tumorigenesis and drug resistance. A member of the forkhead box (FOX) family, FOXC1, assumes significance in embryonic development and organogenesis. Furthermore, FOXC1 functions as an overexpressed transcription factor in various tumors, fostering proliferation, enhancing migratory capabilities, and promoting drug resistance, while maintaining stem-cell-like properties.

TRPM8 inhibits substance P release from primary sensory neurons via PKA/GSK-3beta to protect colonic epithelium in colitis.

Transient receptor potential melastatin 8 (TRPM8) is a cold sensory receptor in primary sensory neurons that regulates various neuronal functions. Substance P (SP) is a pro-inflammatory neuropeptide secreted by the neurons, and it aggravates colitis. However, the regulatory role of TRPM8 in SP release is still unclear.

TAOK3 Facilitates Esophageal Squamous Cell Carcinoma Progression and Cisplatin Resistance Through Augmenting Autophagy Mediated by IRGM.

Esophageal squamous cell carcinoma (ESCC) is one of the deadliest cancers because of its robust aggressive phenotype and chemoresistance. TAO kinase belongs to mitogen-activated protein kinases, which mediate drug resistance in multiple cancers. However, the role of TAO kinase in ESCC progression and chemoresistance has never been explored.
