Cholesterol Depletion ReducesHelicobacter pyloriCagA Translocation and CagA-Induced Responses in AGS Cells [PDF]
ABSTRACTInfection withHelicobacter pylori cagA-positive strains is associated with gastritis, ulcerations, and gastric cancer. CagA is translocated into infected epithelial cells by a type IV secretion system and can be tyrosine phosphorylated, inducing signal transduction and motogenic responses in epithelial cells.

circMAN1A2 as an Isoform‐Resolved Circular RNA Hub in Cancer
circMAN1A2 as an isoform‐resolved circular RNA hub in cancer. circMAN1A2 is generated by back‐splicing of MAN1A2 pre‐mRNA, with alternative circularization producing multiple isoforms, including the predominant circMAN1A2(2–5). Its mechanistic interfaces include miRNA‐associated regulation, RBP binding/proteostasis control, BSJ‐mediated RNA–RNA pairing,

Analysis of Helicobacter pylori cagA Promoter Elements Required for Salt-Induced Upregulation of CagA Expression [PDF]
ABSTRACT Helicobacter pylori infection and consumption of a high-salt diet are each associated with an increased risk for the development of gastric cancer. To investigate potential synergism between these factors, we used a global proteomic approach to analyze H. pylori

ABSTRACT Background Although Helicobacter pylori plays a central role in gastric cancer (GC), other microorganisms involved in gastric dysbiosis may also impact carcinogenesis. We aimed to characterize gastric dysbiosis and its role in the transition from non‐atrophic gastritis (NAG) to gastric premalignant lesions (GPLs) in two populations from Nariño,

Genotyping of the cagA gene of Helicobacter pylori on immunohistochemistry with East Asian CagA‐specific antibody [PDF]
The cytotoxin‐associated antigen A (CagA) of Helicobacter pylori prevalent in East Asian countries, where the mortality rate due to gastric cancer is high, has been reported to be structurally different from that in Western countries, where the gastric cancer mortality rate is relatively low. Based on the structural features of the EPIYA motifs located

While several oncogenic pathogens cause site‐specific cancers, uncertainties remain about many other chronic infections and combined pathogen effects, especially in non‐Western populations. Using a large case–cohort study nested within the China Kadoorie Biobank, the authors found that co‐infection was common, with a mean of 10 pathogens per individual.

Helicobacter pylori cagAPromoter Region Sequences Influence CagA Expression and Interleukin 8 Secretion [PDF]
Heterogeneity at the Helicobacter pylori cagA gene promoter region has been linked to variation in CagA expression and gastric histopathology. Here, we characterized the cagA promoter and expression in 46 H. pylori strains from Portugal. Our results confirm the relationship between cagA promoter region variation and protein expression originally ...

Hypoxia, oncogenic signaling, transcriptional and epigenetic remodeling, and H. pylori–microbiota interactions drive the Warburg effect in gastric cancer. Enhanced glycolysis and lactate export support biosynthesis, remodel the tumor microenvironment, promote stromal activation and immune suppression, and reveal actionable biomarkers and therapeutic ...
