Murine Models of Gastric Corpus PreneoplasiaSummary

open access: yesCellular and Molecular Gastroenterology and Hepatology, 2017
Intestinal-type gastric adenocarcinoma evolves in a field of pre-existing metaplasia. Over the past 20 years, a number of murine models have been developed to address aspects of the physiology and pathophysiology of metaplasia induction. Although none of

Role for Complement C5 in Eosinophilic Inflammation of Severe Asthma

open access: yesAllergy, EarlyView.
Complement activation module, particularly C5, is positively associated with eosinophilic inflammation in severe asthma cohorts. Elevated C5 expression correlates with poor lung function improvement and persistent eosinophilic inflammation. Mouse model studies confirm that C5 exacerbates eosinophilic inflammation, highlighting its potential as a ...

Acetylcholine From Solitary Chemosensory Cell, Not Neuron, Regulates Basal Cell Fate Driving Eosinophilic Chronic Rhinosinusitis With Nasal Polyps

open access: yesAllergy, EarlyView.
This study identifies that Ach levels are elevated in eCRSwNP and primarily released from SCCs rather than neurons. Ach induces epithelial remodeling in eCRSwNP by binding to M1R/M3R and activating YAP signaling in basal cells, driving basal cell hyperplasia and abnormal differentiation. Blocking M1R/M3R with TB inhibits eCRSwNP progression.

hTERT, MYC and TP53 deregulation in gastric preneoplastic lesions

open access: yesBMC Gastroenterology, 2012
Background Gastric cancer is a serious public health problem in Northern Brazil and in the world due to its high incidence and mortality. Despite the severity of the disease, more research is needed to better understand the molecular events involved in ...

Clinical manifestations of precancerous lesions of the stomach: characteristics and warnings

open access: yesGastroenterologìa, 2020
Background. Chronic gastritis is largely associated with clinical manifestations such as dyspepsia, but often, even in a severe form, it is asymptomatic, which causes difficulties in its timely diagnosis.

Lower Risk of Gastric Atrophy and Intestinal Metaplasia in Patients with MALT Lymphoma despite Infection [PDF]

open access: yesThe Korean Journal of Helicobacter and Upper Gastrointestinal Research, 2019
Background/Aims Atrophic gastritis and intestinal metaplasia are sequential consequences of chronic Helicobacter pylori (H. pylori) infection. These conditions are well known to increase the risk of gastric adenocarcinoma development.

The OLGIMA system for gastric cancer risk assessment. A useful method based on the histological Sydney consensus

open access: yesHistopathology, EarlyView.
The new OLGIMA method for histological gastric cancer risk assessment is based on the severity of glandular atrophy and intestinal metaplasia, in both antrum and corpus, according to the Updated Sydney classification. The highest score of either atrophy or intestinal metaplasia from each location will be used for the final OLGIMA stage.

Evaluating Cost‐Effectiveness of 85 Endoscopic Surveillance Strategies of Nondysplastic Barrett's Esophagus

open access: yesJournal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Background Barrett's esophagus is the known precursor to esophageal adenocarcinoma (EAC), a cancer with poor prognosis. While endoscopic surveillance detects early dysplasia and prevents progression, most Barrett's esophagus patients do not progress to EAC, leading to invasive and costly surveillance.
