RAGE participates in the intracellular transport of Campylobacter jejuni cytolethal distending toxin.

Background: Cytolethal distending toxin (CDT) belongs to the genotoxin family and is closely related to Campylobacter jejuni-associated gastroenteritis. We recently reported that CDT triggers the danger-associated molecular pattern (DAMP) signaling to exert deleterious effects on host cells. However, how CDT traffics in cells and the mechanism of CDT intoxication remain to be elucidated.

Gastroprotective Effect of on Aspirin-Induced Gastric Ulcer in Mice.

Gastric ulcers are commonly seen in the upper gastrointestinal tract and may be related to the infection and the use of aspirin, a nonsteroidal anti-inflammatory drug (NSAID). Typically, proton-pump inhibitors (PPIs) are used to treat gastric ulcers; however, adverse effects have emerged following long-term treatment. Natural medicines are used as alternative therapeutic agents in the treatment of gastric ulcers, with few side effects.

Primary Ewing's sarcoma of sphenoid sinus: A case report and literature review.

Background: Primary Ewing's sarcoma of sphenoid sinus, observed in children and adolescents, is an extremely rare malignancy. Such rarity makes the imaging features and treatment strategies for Ewing's sarcoma of sphenoid sinus unclear. This study aimed to offer guidance for treating this very disease by describing a patient with a rare primary Ewing's sarcoma of sphenoid sinus and reviewing the available data in the literature.

Triple-Negative Breast Cancer Analysis Based on Metabolic Gene Classification and Immunotherapy.

Triple negative breast cancer (TNBC) has negative expression of ER, PR and HER-2. TNBC shows high histological grade and positive rate of lymph node metastasis, easy recurrence and distant metastasis. Molecular typing based on metabolic genes can reflect deeper characteristics of breast cancer and provide support for prognostic evaluation and individualized treatment.

Gut Commensal MTS01 Alters Gut Microbiota Composition and Reduces Cholesterol to Mitigate -Induced Pathogenesis.

infection is closely associated with various gastrointestinal diseases and poses a serious threat to human health owing to its increasing antimicrobial resistance. possesses two major virulence factors, vacuolating cytotoxin A (VacA) and cytotoxin-associated gene A (CagA), which are involved in its pathogenesis. Probiotics have recently been used to eradicate infection and reduce the adverse effects of antibiotic-based therapies.

Model for Studying Gut Microbiota in Behaviors and Neurodegenerative Diseases.

Mounting evidence indicates that the gut microbiota is linked to several physiological processes and disease development in mammals; however, the underlying mechanisms remained unexplored mostly due to the complexity of the mammalian gut microbiome. The fruit fly, , is a valuable animal model for studying host-gut microbiota interactions in translational aspects. The availability of powerful genetic tools and resources in allowed the scientists to unravel the mechanisms by which the gut microbes affect fitness, health, and behavior of their hosts.

cholesterol-α-glucosyltransferase manipulates cholesterol for bacterial adherence to gastric epithelial cells.

infection is associated with several gastrointestinal diseases, including gastritis, peptic ulcers, and gastric cancer. Infection of cells with is dependent on lipid rafts, which are cholesterol-rich microdomains located in the cell membrane. cholesterol-α-glucosyltransferase (CGT) catalyzes the conversion of membrane cholesterol to cholesteryl glucosides, which can be incorporated into the bacterial cell wall, facilitating evasion from immune defense and colonization in the host.

Cytolethal Distending Toxin C Exploits Lipid Rafts to Mitigate -Induced Pathogenesis.

infection is associated with several gastrointestinal diseases, including gastritis, peptic ulcer, and gastrointestinal adenocarcinoma. Two major cytotoxins, vacuolating cytotoxin A (VacA) and cytotoxin-associated gene A (CagA), interact closely with lipid rafts, contributing to -associated disease progression. The cytolethal distending toxin consists of three subunits: CdtA, CdtB, and CdtC.

Bacterial Genotoxin-Coated Nanoparticles for Radiotherapy Sensitization in Prostate Cancer.

Prostate cancer (PCa) is one of the most commonly diagnosed cancers in men and usually becomes refractory because of recurrence and metastasis. CD44, a transmembrane glycoprotein, serves as a receptor for hyaluronic acid (HA). It has been found to be abundantly expressed in cancer stem cells (CSCs) that often exhibit a radioresistant phenotype.
