The role of canopy family proteins: biological mechanism and disease function.

Canopy family proteins are highly sequence-conserved proteins with an N-terminal hydrophobic signal sequence, a unique pattern of six cysteine residues characteristic of the saposin-like proteins, and a C-terminal putative endoplasmic reticulum retention signal sequence. At present, the known canopy family proteins are canopy fibroblast growth factor signaling regulator 1 (CNPY1), CNPY2, CNPY3, and CNPY4. Despite similar structures, canopy family proteins regulate complex signal networks to participate in various biological processes.

A Randomized, Comparative Trial of a Potassium-Competitive Acid Blocker (X842) and Lansoprazole for the Treatment of Patients with Erosive Esophagitis.

Introduction: X842 is a new type of gastric acid-suppressing agent with a rapid onset of action and a long duration of effect. We aim to investigate the efficacy and safety of different doses of X842 versus lansoprazole in the treatment of patients with erosive esophagitis (EE).

Methods: This phase 2 study included 90 patients with EE (Los Angeles grades A-D) who were randomized (1:1:1) to receive oral low-dose X842 (50 mg/day, n=31), high-dose X842 (100 mg/day, n=31), or lansoprazole (30 mg/day, n=30) for 4 weeks.

Helicobacter pylori CagA promotes gastric cancer immune escape by upregulating SQLE.

Helicobacter pylori (H. pylori) infection is a well-established risk factor for gastric cancer, primarily due to its virulence factor, cytotoxin-associated gene A (CagA). Although PD-L1/PD-1-mediated immune evasion is critical in cancer development, the impact of CagA on PD-L1 regulation remains unclear.

Unraveling the tumor microenvironment of esophageal squamous cell carcinoma through single-cell sequencing: A comprehensive review.

Esophageal squamous cell carcinoma (ESCC) is a highly heterogeneous and aggressive malignancy. The progression, invasiveness, and metastatic potential of ESCC are shaped by a multitude of cells within the tumor microenvironment (TME), including tumor cells, immune cells, endothelial cells, as well as fibroblasts and other cell types. Recent advancements in single-cell sequencing technologies have significantly enhanced our comprehension of the diverse landscape of ESCC.

Immune-mediated liver injury caused by immune checkpoint inhibitors exhibits distinct clinical features that differ from autoimmune hepatitis.

Background: Immune-mediated liver injury caused by immune checkpoint inhibitors (ILICI) and autoimmune hepatitis (AIH) are both related to the distorted immune system. However, ILICI differs from AIH in several distinct ways. We aimed to study the differences between ILICI and AIH.

Euglena gracilis polysaccharide modulated gut dysbiosis of obese individuals via acetic acid in an in vitro fermentation model.

Gut dysbiosis is a characteristic feature of obesity and targeting gut microbiota presents a promising approach to attenuate obesity. Euglena gracilis polysaccharide (EGP) has emerged as a potential prebiotic capable of promoting health-beneficial bacteria. However, its effects on the gut dysbiosis of obese individuals remain unclear.

PANoptosis-related genes: Molecular insights into immune dysregulation in ulcerative colitis.

Background And Aim: Ulcerative colitis (UC) is a chronic inflammatory disease driven by immune dysregulation. PANoptosis, a novel form of programmed cell death, has been implicated in inflammatory diseases, but its specific role in UC remains unclear. This study aimed to identify PANoptosis-related genes (PRGs) that may contribute to immune dysregulation in UC.

[Retracted] miR‑92a‑3p promotes the proliferation, migration and invasion of esophageal squamous cell cancer by regulating PTEN.

Following the publication of this paper, a concerned reader drew to the Editor's attention that it appeared as if the authors had calculated the apoptotic rates erroneously. The authors were asked to provide an explanation to account for the concerns raised by the interested reader; however, they did not respond to this request submitted by the Editorial Office. Therefore, owing to the lack of responsiveness on the part of the authors, the Editor of has decided that this paper should be retracted from the journal.

Risk of Clostridioides difficile infection in inflammatory bowel disease patients undergoing vedolizumab treatment: a systematic review and meta-analysis.

Background: Inflammatory bowel disease (IBD) is a chronic, relapsing condition wherein biologics have improved disease prognosis but introduced elevated infection susceptibility. Vedolizumab (VDZ) demonstrates unique safety advantages; however, a comprehensive systematic comparison regarding the risk of Clostridioides difficile infection (CDI) between vedolizumab and alternative medications remains absent.

Method: Medline, Embase, Cochrane, and clinicaltrials.

Clinical performance of a particle enhanced turbidimetric immunoassay (PETIA) for detecting fecal calprotectin.

Particle-enhanced turbidimetric immunoassay (PETIA) is a new measurement procedure for detecting fecal calprotectin (FC). We aimed to investigate the accuracy and clinical performance of PETIA for FC. We assessed the accuracy of PETIA for FC measurements through concordance analysis, Passing-Bablok regression and Bland-Altman analysis, using enzyme-linked immunosorbent assay (ELISA) as the reference.

Clinical features and risk of multiple primary malignancies after endoscopic treatment in patients with early esophageal squamous cell carcinoma: a retrospective cohort study.

Background: The incidence of multiple primary malignancies (MPMs) after early esophageal cancer is increasing. This study aimed to explore the clinical features of patients with MPMs and identify independent risk factors for the development of MPMs after endoscopic treatment in early esophageal squamous cell carcinoma (ESCC) patients.

Methods: Patients diagnosed as early ESCC at Beijing Friendship Hospital were retrospectively analyzed.

PTOV1 facilitates colorectal cancer cell proliferation through activating AKT1 signaling pathway.

Background: Colorectal cancer is a predominant contributor to global cancer-related morbidity and mortality. The oncogene PTOV1 has been linked to various human malignancies, yet its specific role in CRC pathogenesis requires further elucidation.

Methods: Our study used a comprehensive array of authoritative bioinformatics tools, such as TIMER, UCSC Xena, GEO, Human Protein Atlas, UALCAN, CIBERSORTx and others which used to investigate the complex effects of PTOV1 on gene expression profiles, diagnostic and prognostic biomarkers, tumor immunology, signaling pathways, epigenetic alterations, and genetic mutations.

Closure methods for large defects after gastrointestinal endoscopic submucosal dissection.
