Regeneration of gastric mucosa in rats [PDF]

open access: yesAmerican Journal of Anatomy, 1961
Since Bensley's ( 1898) classical description of the specialized cell types in the gastric mucosal epithelium much uncertainty has existed concerning their life history. Grant ('45), Stevens and Leblond ('53), Hunt ('57) and Messier ('60) observed that both surface and mucous neck cells arise from the proliferation of cells in the neck region of the ...

Diagnosis of autoimmune gastritis in patients with different status of Нelicobacter pylori infection: a medical decision support system

open access: yesЛечащий Врач
Background. Autoimmune inflammation in the gastric mucosa and Helicobacter pylori (H. pylori) infection are the main etiologic factors of chronic gastritis. Diagnostics of H.

Effect of hydrogen sulfide-releasing aspirin on esophageal and gastric mucosa compromised by stress injury [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2017
Recent data of study H2S in gastrointestinal tract has proven its potent cytoprotection on mucosal defense among acid-related diseases in the gut. The aim was to evaluate the effects of H2S-releasing aspirin derivative (ATB-340) on esophageal and gastric

Genome‐Wide In Vivo RNAi Screening Identifies HOXD4 as a Tumor Metastasis Suppressor in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
Metastasis remains a major challenge in colorectal cancer. Using an in vivo shRNA screening system, this study identifies Homeobox D4 as a key metastasis suppressor. Reduced Homeobox D4 expression is associated with aggressive tumor features. Functional and mechanistic analyses show that it inhibits epithelial‐mesenchymal transition by repressing ...

Integrative roles of transforming growth factor-α in the cytoprotection mechanisms of gastric mucosal injury

open access: yesBMC Gastroenterology, 2006
Background Transforming growth factor α (TGFα) protects against gastric mucosal injury and facilitates wound healing. However, its overexpression is known to induce hypertrophic gastropathy resembling Menetrier's disease in transgenic (TG) mice on an FVB

Loss of E3 Ubiquitin Ligase RINES via CpG Methylation Relieves Suppression of STAT3 and MYC, Facilitating Multiple Tumorigeneses

open access: yesAdvanced Science, EarlyView.
Dysregulated protein modifications drive tumorigenesis. RINES, an E3 ubiquitin ligase, represses tumor cell proliferation and metastasis by facilitating RING domain‐dependent, ubiquitin–proteasome‐mediated degradation of STAT3 and MYC, which consequently restrains cancer stemness and oncogenic progression.

The pepsinogens of human gastric mucosa [PDF]

open access: yesGut, 1973
Fundic mucosal pepsinogens reveal six major bands of protease activity on gel electrophoresis and four minor bands. Antral mucosa shows two major bands of activity; the four rapidly moving bands found in fundic mucosa are found in lesser activity in the antral mucosa. Duodenal mucosa shows only one slowly moving band of protease activity.

Transferable Deep Reinforcement Learning With Edge‐Contour‐Depth Fusion for Autonomous Wireless Capsule Endoscopy Navigation

open access: yesAdvanced Science, EarlyView.
This study presents an anatomical landmark‐guided DRL framework for autonomous wireless capsule endoscopy navigation. Using a lightweight edge‐contour‐depth fusion module, it achieves over 97% coverage across diverse gastric anatomies. To ensure reliability, a two‐stage sim‐to‐real pipeline with an adaptive dynamic programming controller mitigates ...
