[PMID: 38012972 DOI: 10.1016/j.jep.2023.117494] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 11/17/2023] [Accepted: 11/21/2023] [Indexed: 11/29/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The herbal pair Alpinia officinarum-Cyperus rotundus (HPAC) has an extended history of use in the treatment of gastric ulcers, and its curative effect is definite. AIM OF THE STUDY To explore the material basis and holistic mechanism of HPAC on ethanol-induced gastric ulcers. MATERIALS AND METHODS Three chemometrics, GRA, OPLS, and BCA, were used to construct the spectrum-effect relationship between the HPLC fingerprints of HPAC extracts and the bioactivity indices (cell viability; the levels of TNF-α, IL-6, COX-2, and PGE2; and wound healing rate) against GES-1 cell damage to screen the bioactive ingredients. The bioactive components were isolated and validated in vitro. Simultaneously, the effects of HPAC with concentrated bioactive ingredients was tested on ethanol-induced gastric ulcers in vivo, and the mechanism was investigated using transcriptomics and metabolomics. The mechanism was further validated by Western blotting. Finally, the contents of the main components of HPAC were determined before and after compatibility. RESULTS Twelve bioactive components were screened, and the structures of nine compounds were confirmed. An in vitro verification test showed that DPHA and galangin could protect GES-1 cells from injury, and that their content increased after compatibility. The CH2Cl2 fraction of HPAC (HP-CH2Cl2) can protect mice from ethanol-induced gastric mucosal injury by reducing hemorrhage and decreasing inflammatory cell infiltration. Western blot analysis indicated that this fraction may up-regulate TRPV1 protein and down-regulate PI3K and AKT proteins. CONCLUSIONS DPHA and galangin may be the bioactive components against ethanol-induced GES-1 cell injury. HP-CH2Cl2 may exert gastroprotective effects by regulating PI3K, AKT and TRPV1 proteins.

Lv Y, Li J, Li Y, Su J, Ding X, Yuan Y, Liu S, Mou Y, Li G, Zhang L. Unveiling the potential mechanisms of Amomi fructus against gastric ulcers via integrating network pharmacology and in vivo experiments. JOURNAL OF ETHNOPHARMACOLOGY 2024; 319:117179. [PMID: 37777029 DOI: 10.1016/j.jep.2023.117179] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 09/04/2023] [Accepted: 09/11/2023] [Indexed: 10/02/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As a well-known traditional Chinese medicine, Amomi fructus (A. fructus) (Sharen) has been used therapeutically to treat gastrointestinal illnesses, including gastric ulcer (GU). The mechanism underlying this impact is still not fully known, though. AIM OF THE STUDY To investigate the hidden mechanism by which A. fructus influences the pathogenesis of GU, we employed network pharmacology approaches and in vivo validated studies. MATERIALS AND METHODS Multiple public databases were used to compile information on bioactive compounds, potential targets of A. fructus, and associated genes of GU. Then, the STRING database's protein-protein interaction (PPI) data of the drug-disease overlapping gene targets was obtained, and the core targets for A. fructus against GU were discovered. Additionally, molecular docking was done to examine the binding capabilities of the active substances and core targets. Then, the pathways of A. fructus that target GU were examined using the Annotation, Visualization and Integrated Discovery (DAVID)'s Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway studies. In a mouse model of acute stomach mucosal damage brought on by absolute ethanol, the findings of network pharmacology were finally validated. RESULTS In total, 610 targets derived from the 196 bioactive compounds in A. fructus, were discovered, and along with 115 A. fructus target genes for therapy of GU. Then, ten core targets associated with apoptosis and inflammation were determined based on node degree, and ALB, AKT1, TNF, EGFR, MAPK3, CASP3, MMP9, STAT3, SRC, and HRAS were identified as promising therapeutic targets of A. fructus against GU. The results of molecular docking also revealed that 65 active compounds had strong binding activity with the core targets, with volatile chemicals being the most significant active ingredients. So, for following in vivo tests, A. fructus volatile oils (AVO) were used. The KEGG analysis showed that the phosphoinositide-3-kinase/protein kinase B (PI3K/AKT) signaling pathway may be crucial for the therapeutic mechanism of GU. In experiments that were validated in vivo, AVO considerably decreased the ulcer area and enhanced the histological appearance of the gastric tissues. In addition, compared to the model group, up-regulated the expression of IGF-1, p-PI3K, and p-AKT and down-regulated the protein levels of TNF-α and Caspase 3 in the stomach tissues. CONCLUSION According to preliminary findings from this work, A. fructus may influence inflammatory response and apoptosis via regulating the PI3K/AKT signaling pathway and associated gene targets. Importantly, our research might offer a theoretical foundation for future research into the intricate anti-GU mechanism of A. fructus.

Abstract
Gastroesophageal Reflux Disease (GERD) is a chronic ailment that results from the backward flow of stomach acid into the esophagus, causing heartburn and acid regurgitation. This review explores nanotechnology as a novel treatment approach for GERD. Chitosan nanoparticles (CSNPs) offer several advantages, including biocompatibility, biodegradability, and targeted drug delivery capabilities. CSNPs have been extensively studied due to their ability to encapsulate and release medications in a controlled manner. Different nanoparticle (NP) delivery systems, including gels, microspheres, and coatings, have been developed to enhance drug retention, drug targeting, and controlled release in the esophagus. These nanoparticles can target specific molecular pathways associated with acid regulation, esophageal tissue protection, and inflammation modulation. However, the optimization of nanoparticle formulations faces challenges, including ensuring stability, scalability, and regulatory compliance. The future may see CSNPs combined with other treatments like proton pump inhibitors (PPIs) or mucosal protectants for a synergistic therapeutic approach. Thus, CSNPs provide exciting opportunities for novel GERD treatment strategies.

[PMID: 36159581 PMCID: PMC9507741 DOI: 10.1155/2022/4743041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Accepted: 08/27/2022] [Indexed: 11/18/2022]
Abstract
Gastric ulcer is an injury that develops on the lining of the stomach due to an imbalance between aggressive and defensive agents. Chitosan derivatives demonstrate promising biological activities in accelerating the healing activity of gastric lesions. Thus, this study aimed at investigating the healing activity of gastric lesion, induced by acetic acid (80%), of the chitosan derivative with acetylacetone (Cac) modified with ethylenediamine (Cacen) or diethylenetriamine (Cacdien). The biological activity was determined based on cytotoxicity, antibacterial activity, and gastroprotective activities. The results showed no significant difference in the cytotoxicity, a better antibacterial activity against S. aureus and E. coli, and a positive result on the healing of gastric lesions of the materials (Cac 18.4%, Cacen 55.2%, and Cacdien 68.1%) compared to pure chitosan (50.7%). Therefore, the results indicate that derivatives of chitosan are promising biomaterials for application in the control of lesions on the gastric mucosa.

Uncovering the pharmacological mechanism of Wei-Tong-Xin against gastric ulcer based on network pharmacology combined with in vivo experiment validation. JOURNAL OF ETHNOPHARMACOLOGY 2022; 293:115282. [PMID: 35405254 DOI: 10.1016/j.jep.2022.115282] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Revised: 02/27/2022] [Accepted: 04/05/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The prescription of Wei-Tong-Xin (WTX) is improved based on the prescription "Wanyingyuan", a famous decoction documented in the book of Huatuozhongzangjing in the Han dynasty. Many years of clinical verification have demonstrated that WTX can be used to treat gastrointestinal diseases, especially gastric ulcer (GU). However, the potential pharmacological mechanism is undefined. AIM OF THE STUDY This research was conducted to explore the pharmacological mechanisms under the consideration of the therapeutical effect of WTX against GU by combining the network pharmacology strategy and in-vivo verified experiments. MATERIALS AND METHODS A prediction network describing the relationship between WTX and GU was established based on information collected from multiple databases. Then, the intersecting protein-protein interaction (PPI) network of the drug-disease overlapping gene targets was constructed, and several key targets related to both WTX and GU were obtained. Besides, the Gene Ontology (GO) biological enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed to investigate the key target genes and pathways of WTX against GU. Then, the candidate targets and signaling pathways of network pharmacology were validated in a rat model of GU induced by indomethacin following the results and available proof. RESULTS There are 243 targets obtained from the 65 active ingredients in WTX, and 1362 disease targets related to GU were identified. Then, 6 key targets were determined with the PPI interaction network, which was structured from 126 overlapping gene targets. GO and KEGG analyses revealed that the phosphoinositide-3-kinase/protein kinase B (PI3K/AKT) signaling pathway might play a crucial role in the therapeutic mechanism of GU. In vivo verified experiments, WTX significantly reduced the ulcer area and improved the histopathological appearance of gastric tissues. Moreover, down-regulated the protein levels of IL6, TNF-α, and Caspase 3 in the gastric tissues while up-regulating the expression of p-PI3K, p-AKT, p-P53, and VEGFA compared to the model group. CONCLUSION WTX, an ancient traditional Chinese medicine (TCM) compound prescription, may affect the inflammatory response and apoptosis process by regulating PI3K/AKT signaling pathway and related gene targets. Therefore, it is an effective drug candidate for the modern treatment of GU.

Abstract
PURPOSE OF REVIEW The mucosal barrier serves as a primary interface between the environment and host. In daily life, superficial injury to the gastric or duodenal mucosa occurs regularly but heals rapidly by a process called 'restitution'. Persistent injury to the gastroduodenal mucosa also occurs but initiates a regenerative lesion with specific wound healing mechanisms that attempt to repair barrier function. If not healed, these lesions can be the site of neoplasia development in a chronic inflammatory setting. This review summarizes the past year of advances in understanding mucosal repair in the gastroduodenal mucosa, which occurs as a defense mechanism against injury. RECENT FINDINGS Organoids are an emerging new tool that allows for the correlation of in vivo and in vitro models; organoids represent an important reductionist model to probe specific aspects of injury and repair mechanisms that are limited to epithelial cells. Additionally, proof-of-concept studies show that machine learning algorithms may ultimately assist with identifying novel, targetable pathways to pursue in therapeutic interventions. Gut-on-chip technology and single cell RNA-sequencing contributed to new understanding of gastroduodenal regenerative lesions after injury by identifying networks and interactions that are involved in the repair process. SUMMARY Recent updates provide new possibilities for identifying novel molecular targets for the treatment of acute and superficial mucosal injury, mucosal regeneration, and regenerative lesions in the gastrointestinal tract.
