Pentagalloyl Glucose, a Major Compound in Mango Seed Kernel, Exhibits Distinct Gastroprotective Effects in Indomethacin-Induced Gastropathy in Rats via Modulating the NO/eNOS/iNOS Signaling Pathway. Front Pharmacol 2022; 13:800986. [PMID: 35211013 PMCID: PMC8862146 DOI: 10.3389/fphar.2022.800986] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2021] [Accepted: 01/10/2022] [Indexed: 11/13/2022] Open
Abstract
Gastric ulcers are a common health disorder that affect up to 10% of the world’s population. The gastroprotective potential of pentagalloyl glucose (PGG) against indomethacin-induced ulcer in rats and the possible underlying mechanisms were investigated. Gastric ulceration was induced by indomethacin (single dose, 60 mg/kg). Pretreatment with PGG (100 or 200 mg/kg, orally) for 8 days prior to the administration of indomethacin furnished significant reductions in gastric mucosal lesions as well as a significant increase in mucus concentration. Also, PGG significantly declined the elevations in gastric mucosal MDA, TNF-α, IL-6, PECAM-1, VEGF, and iNOS expression. It also mitigated the decrease in GSH and GPx and eNOS expression observed with indomethacin. The protective effects furnished by PGG were comparable to that of famotidine. The obtained results suggested that the anti-ulcer effects of PGG are mediated by increasing mucus production, scavenging free radicals, decreasing inflammation, and attenuating the NO/NOS signaling in favor of eNOS. To sum up, PGG could provide a potential therapy for gastric ulcer after evaluating its efficacy and effectiveness.

Abstract
Banana is one of the most nutritious fruits, as it is rich in carbohydrates, proteins, fatty acids, and minerals. Banana has been used in traditional medicines for managing coughs and colds, ulcers, burns, and diarrhea. Banana contains various bioactive compounds, such as alkaloids, phenols, flavonoids, tannins, and saponins, with reported therapeutic benefits, including antioxidant, anti-diabetic, anti-cancer, anti-inflammatory, and anti-microbial activities. The present review focuses on a comprehensive overview of the nutritional and biological properties and phytochemicals of different species of banana and its different parts. Although detailed characterization of the compounds that are present in many parts of the plant has been carried out, chemical profiling of the seed, pseudostem, and leaves of banana is lacking and requires further exploration. Moreover, the functions of the reported compounds were elucidated using computational tools, supporting their potential role in managing life-threatening diseases and physiological complications.

Inhibition of caspase-3-mediated GSDME-derived pyroptosis aids in noncancerous tissue protection of squamous cell carcinoma patients during cisplatin-based chemotherapy. Am J Cancer Res 2020; 10:4287-4307.

Abstract
The side effects of platinum-based chemotherapy are important factors limiting the survival of oral squamous cell carcinoma (OSCC) patients. Current research suggests that pyroptosis is involved in this process. However, how this mechanism can be used to reduce side effects has not yet been elucidated. In this study, we reported that GSDME was expressed at higher levels in normal tissues than in cancerous tissues in OSCC patients and was the main cause of platinum-based side effects. In an OSCC xenograft model, the inflammatory status and GSDME expression were increased after cisplatin chemotherapy. Cellular experiments showed that higher expression of GSDME was associated with less chemoresistance to cisplatin. A subsequent study demonstrated that cisplatin treatment promotes the maturation of caspase-3, triggers GSDME-mediated pyroptosis and induces cell death. When the amino acid sequence of GSDME cleaved by caspase-3 was mutated, cellular death and pyroptosis induced by cisplatin were significantly inhibited. Moreover, application of vitamin D during cisplatin-based chemotherapy could successfully inhibit GSDME cleavage and pyroptotic cell death in vitro and in vivo. Taken together, our study revealed that vitamin D can inhibit caspase-3-mediated GSDME cleavage and thus reduce normal tissue pyroptosis, relieving chemotherapeutic side effects. Inhibition of systemic GSDME during chemotherapy is currently unachievable. Vitamin D supplementation during chemotherapy in OSCC patients might be able to reduce the process described above and benefit patients. However, additional follow-up clinical studies are needed.

Efficacy of a new nutraceutical formulation (CHETOGERD ®) in patients with nonerosive reflux disease (NERD): a prospective observational study. Intern Emerg Med 2020; 15:1265-1269. [PMID: 32198722 DOI: 10.1007/s11739-020-02309-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2020] [Accepted: 03/05/2020] [Indexed: 02/07/2023]
Abstract
Nonerosive reflux disease (NERD) is a gastrointestinal disorder that leads to symptoms such as heartburn and regurgitation without visible esophageal mucosal injury, and it is treated with proton-pump inhibitors (PPIs). CHETOGERD® gel or orosoluble (oro) formulations-an association of natural active ingredient: hyaluronic acid, altea, malva, apple active TM, Aloe vera, L-triptophan, calcium gluconate, sodium bicarbonate, Musa paradisiaca)-may be an alternative or a coadjutant treatment in patients with NERD. The aim of the study was to evaluate, prospectively, the efficacy of CHETOGERD® gel and oro in inducing symptom's reduction or remission, in consecutive patients with NERD. Patients were divided in two groups and treated with CHETOGERD® gel or CHETOGERD® oro, 3 sachets/day for 3 months, decreased to 1 sachet/day for other 3 months. Symptoms were evaluated at baseline, 3 and 6 months using the reflux disease questionnaire (RDQ). Symptoms' remission was defined as reduction of retrosternal pain or burning, epigastric pain or burning, regurgitation and acid sensation in mouth. Frequency, distribution analyses and non-parametric tests were used for the statistical analysis. Results were considered statistically significant for p values < 0.05. Four hundred and twenty-three patients (M/F 240/183; mean age 50 years) were diagnosed with NERD and were consecutively enrolled. 146 patients underwent therapy with CHETOGERD® gel, while 277 were treated with CHETOGERD® oro. 108 patients from the first group and 172 patients from the second group completed follow up at 3 months, while 100 patients from each group completed follow-up at 6 months. Both formulations were able to significantly reduce the frequency and intensity of symptoms analysed with RDQ. No adverse events were reported. CHETOGERD® gel and oro are two valid alternatives to control symptoms in patients with nonerosive reflux disease.

Abstract
PURPOSE OF REVIEW The gastroduodenal mucosal layer is a complex and dynamic system that functions in an interdependent manner to resist injury. We review and summarize the most updated knowledge about gastroduodenal defense mechanisms and specifically address (a) the mucous barrier, (b) membrane and cellular properties, and vascular, hormonal, and (c) gaseous mediators. RECENT FINDINGS Trefoil factor family peptides play a crucial role in cellular restitution by increasing cellular permeability and expression of aquaporin channels, aiding cellular migration and tissue repair. Additionally, evidence suggests that the symptoms of functional dyspepsia may be attributed to alterations in the duodenum, including low-grade inflammation and increased mucosal permeability. The interaction of the various mucosal protective components helps maintain structural and functional homeostasis. There is increasing evidence suggesting that the upper GI microbiota plays a crucial role in the defense mechanisms. However, this warrants further investigation.
