H. Pylori-Facilitated TERT/Wnt/β-Catenin Triggers Spasmolytic Polypeptide-Expressing Metaplasia and Oxyntic Atrophy.

Persistent H. pylori infection triggers the repair program of the mucosa, such as spasmolytic polypeptide-expressing metaplasia (SPEM). However, the mechanism underlying the initiation of SPEM in gastric tissues by H.

Plant mucus-derived microgels: Blood-triggered gelation and strong hemostatic adhesion.

Arrest of bleeding usually applies clotting agents to trigger coagulation procedures or adhesives to interrupt blood flow through sealing the vessel; however, the efficiency is compromised. Here, we propose a concept of integration of hemostasis and adhesion via yam mucus's microgels. The mucus microgels exhibit attractive attributes of hydrogel with uniform size and shape.

Comprehensive profiling of cell subsets of gastric cancer and liver metastasis based on single cell RNA-sequencing analysis.

Background: Liver metastasis (Li) is one of the most common distant metastatic sites for gastric cancer. A deeper understanding of its mechanism of action from a bioinformatics perspective may provide new insights. Therefore, the aim of this study was to use single cell RNA sequencing (scRNA-seq) to evaluate cell subtypes and understand the molecular mechanism of gastric cancer Li.

Plasma and urine proteomics and gut microbiota analysis reveal potential factors affecting COVID-19 vaccination response.

The efficacy of COVID-19 vaccination relies on the induction of neutralizing antibodies, which can vary among vaccine recipients. In this study, we investigated the potential factors affecting the neutralizing antibody response by combining plasma and urine proteomics and gut microbiota analysis. We found that activation of the LXR/FXR pathway in plasma was associated with the production of ACE2-RBD-inhibiting antibodies, while urine proteins related to complement system, acute phase response signaling, LXR/FXR, and STAT3 pathways were correlated with neutralizing antibody production.

RNF112-mediated FOXM1 ubiquitination suppresses the proliferation and invasion of gastric cancer.

Forkhead box M1 (FOXM1) plays a critical role in development physiologically and tumorigenesis pathologically. However, insufficient efforts have been dedicated to exploring the regulation, in particular the degradation of FOXM1. Here, the ON-TARGETplus siRNA library targeting E3 ligases was used to screen potential candidates to repress FOXM1.

Is an Independent Prognostic Factor that Promotes the Progression of Colon Cancer.

Trigger transposable element-derived 1 () is a human-specific gene, but no studies have been conducted to determine its mechanism of action. Our aim is to ascertain the function and mode of action of in the development of colon cancer. The authors used bioinformatics to analyze the relationship between and the clinical characteristics of colon cancer, as well as its prognosis.

and unignorable extragastric diseases: Mechanism and implications.

Considered as the most popular pathogen worldwide, is intensively associated with diverse gastric diseases, including gastric ulcers, chronic progressive gastritis, and gastric cancer. Aside from its pathogenic effect on gastric diseases, growing evidences reveal that may be related to numerous extragastric diseases. In this article, we reviewed recent studies and systematically elucidated that may interfere with many biological processes outside the stomach and influence the occurrence of various extragastric diseases.

Nature-Derived Okra Gel as Strong Hemostatic Bioadhesive in Human Blood, Liver, and Heart Trauma of Rabbits and Dogs.

Bioadhesive performance can be compromised due to bleeding. Bleeding increases mortality. Adhesives with hemostatic function are of great significance.

Helicobacter pylori infection induces stem cell-like properties in Correa cascade of gastric cancer.

Gastric cancer (GC) is the fourth leading cause of cancer-related death. Its poor prognosis is attributed to unclear pathogenesis. Currently, the most widely accepted model for elucidating the mechanism of GC is the Correa cascade, which covers several histological lesions of the gastric mucosa.

An acidic polysaccharide from Oxalis corniculata L. and the preliminary study on its antioxidant activity.

It has been reported that the aqueous extract from Oxalis corniculate has excellent pharmacological effects, but its polysaccharide as the major ingredient in the aqueous extract has not been reported. When the temperature of 50°C, ultrasonic power of 270 W, time of 25 min, solid to liquid ratio of 30 ml·g , the optimal O. corniculate polysaccharide (OCP) yield was 9.

Proteolysis-targeting chimeras: A promising technique in cancer therapy for gaining insights into tumor development.

Proteolysis-targeting chimeras (PROTACs) are small molecules that specifically link E3 ubiquitin ligases to proteins of interest to mediate targeted ubiquitination and degradation. PROTACs are advantageous since they can target undruggable proteins with multiple domains, particularly those with smooth surfaces that lack a common binding domain for small-molecule inhibitors (SMIs). This review provides an overview of PROTAC technology and third-generation PROTAC development.

Different Effects of Leucine Supplementation and/or Exercise on Systemic Insulin Sensitivity in Mice.

Objective: Obesity-related diseases such as diabetes, hypertension, dyslipidemia, and cardiovascular diseases have increased due to the obesity epidemic. Early intervention for obesity through lifestyle and nutrition plays an important role in preventing obesity-related diseases. Therefore, the purpose of this study is to explore the role of leucine and exercise in adiposity, systemic insulin resistance, and inflammation to provide theoretical and guiding basis for the early prevention and treatment of obesity.

Corrigendum to "Viscosity and degradation controlled injectable hydrogel for esophagealendoscopic submucosal dissection" [Bioact. Mater. 6 (2021) 1150-1162].

Viscosity and degradation controlled injectable hydrogel for esophageal endoscopic submucosal dissection.

Endoscopic submucosal dissection (ESD) is a common procedure to treat early and precancerous gastrointestinal lesions. Via submucosal injection, a liquid cushion is created to lift and separate the lesion and malignant part from the muscular layer where the formed indispensable space is convenient for endoscopic incision. Saline is a most common submucosal injection liquid, but the formed liquid pad lasts only a short time, and thus repeated injections increase the potential risk of adverse events.

Microwave-assisted extraction, physicochemical characterization and bioactivity of polysaccharides from Camptotheca acuminata fruits.

Microwave-assisted extraction of polysaccharides from Camptotheca acuminate (CAPs) was optimized by response surface methodology. The optimal parameters were as follows: microwave power, 600 W; liquid-solid ratio, 40:1 g/mL; extraction time, 14 min; and extraction temperature, 70 °C. Under these conditions, the yield of CAPs reached up to 8.
