No Potassium, No Acid: K+Channels and Gastric Acid Secretion

, 2007
The gastric H+-K+-ATPase pumps H+ into the lumen and takes up K+ in parallel. In the acid-producing parietal cells, luminal KCNE2/KCNQ1 K+ channels play a pivotal role in replenishing K+ in the luminal fluid.

Cancer‐Associated Fibroblasts Promote Tumor Immunosuppression in Hepatocellular Carcinoma via the NNMT‐ANGPTL4 Axis

Advanced Science, EarlyView.
ABSTRACT Background & Aims: Cancer‐associated fibroblasts (CAFs) drive immunosuppression in hepatocellular carcinoma (HCC). However, their metabolic regulation remains poorly defined. We investigated the role of nicotinamide N‐methyltransferase (NNMT) in CAFs. Approach & Results: High NNMT expression in CAF tissues was confirmed by western blotting and

A novel gastric ulcer model in rats using filter paper with acetic acid

Gastric ulcer animal models are essential for research, but conventional acetic acid-based methods are limited by technical complexity, prolonged modeling duration, and poor applicability for solid anti-ulcer drug testing.

Pharmacologic Modulation of ARID3A with Rimegepant Reactivates Type I Interferon Signaling and Sensitizes Triple‐Negative Breast Cancer to PD‐1 Blockade

Advanced Science, EarlyView.
This study identifies ARID3A as a key immunosuppressive transcription factor in TNBC. Its inhibition activates the type I IFN pathway, boosting CD8+ T cell infiltration and sensitizing tumors to anti‐PD‐1. The FDA‐approved migraine drug Rimegepant targets ARID3A, enhances immunotherapy efficacy in preclinical models, and establishes a druggable axis to

A model study of the regulation of gastric acid secretion

, 1989
A computer simulation model is presented of the gastric phase regulation of gastric acid secretion in humans. The model is based on experimental data from the literature and includes terms representing gastric pH and gastric volume-dependent gastrin ...

Enhancing CAR‐T Cell Efficacy in Solid Tumors by Inhibiting CCL5/VEGF‐Mediated Angiogenesis

Advanced Science, EarlyView.
This study reveals that CAR‐T cells in solid tumors produce CCL5, which paradoxically induces VEGF and angiogenesis to promote tumor growth. Blocking CCL5/VEGF signaling—through gene knockout, or the CCR5 inhibitor maraviroc—significantly enhances the antitumor efficacy of CAR‑T therapy (the diagram was created in Biorender).

The influence of low versus high fibre haylage diets in combination with training or pasture rest on equine gastric ulceration syndrome (EGUS)

, 2007
The aim of this field study was to examine the influence of a low fibre (LF) and a high fibre (HF) diet on the presence of gastric ulceration in thirty 3-year old Dutch Warmblood horses during training period and during pasture rest. In the first part of

ETHANOL EXTRACT TURMERIC (Curcuma domestica val) IN PREVENTING AN INCREASED GASTIC ACIDITY ON Rattus norvegicus WHICH INDUCED BY HISTAMINE

Jurnal Ilmiah Kedokteran Wijaya Kusuma, 2017
Gastric ulcer is one of the increase gastric acid causes which mediated by H2 reseptor. Tumeric is extracted using the ethanol 96% and it is tested using Rattus norvegicus Wistar strain to know the effect as anti gastritis. There’s a suspicion whether an

A Chirality‐Converted Bacteriolytic Dodecapeptide Regulates Vibrio‐Induced Polymicrobial Infection and Ameliorates Invasion‐Associated Gut Microbiota Disequilibrium

Advanced Science, EarlyView.
Multidrug‐resistant Vibrio infections are rising rapidly and threaten coastal populations worldwide. This study introduces D‐zp37, a chirality‐engineered antimicrobial peptide with exceptional potency against resistant Vibrio species. D‐zp37 kills planktonic cells, blocks mixed‐species biofilms, disrupts essential bacterial stress responses, and shows ...
