[PMID: 39254870 DOI: 10.1007/s11010-024-05110-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2024] [Accepted: 08/27/2024] [Indexed: 09/11/2024]
Abstract
Chronic obstructive pulmonary disease (COPD) is a deteriorating condition triggered by various factors, such as smoking, free radicals, and air pollution. This worsening disease is characterized by narrowing and thickening of airways, painful cough, and dyspnea. In COPD, numerous genes as well as microRNA (miRNA) play a significant role in the pathogenesis of the disease. Many in vivo and in vitro studies suggest that upregulation or suppression of certain miRNAs are effective treatment options for COPD. They have been proven to be more beneficial than the current symptomatic treatments, such as bronchodilators and corticosteroids. MiRNAs play a crucial role in immune cell development and regulate inflammatory responses in various tissues. MiRNA treatment thus allows for precision therapy with improved outcomes. Nanoparticle drug delivery systems such as polymeric nanoparticles, inorganic nanoparticles, dendrimers, polymeric micelles, and liposomes are an efficient method to ensure the biodistribution of the miRNAs to the target site. Identification of the right nanoparticle depending on the requirements and compatibility is essential for achieving maximum therapeutic effect. In this review, we offer a thorough comprehension of the pathology and genetics of COPD and the significance of miRNAs concerning various pathologies of the lung, as potential targets for treating the disease. The present review offers the latest insights into the nanoparticle drug delivery systems that can efficiently carry and deliver miRNA or antagomirs to the specific target site and hence help in effective management of COPD.

Investigation into the potential mechanism and therapeutic targets of Cangzhu Erchen decoction for the treatment of chronic obstructive pulmonary disease based on bioinformatics and network pharmacology. Medicine (Baltimore) 2024; 103:e39338. [PMID: 39151493 PMCID: PMC11332823 DOI: 10.1097/md.0000000000039338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2024] [Revised: 07/20/2024] [Accepted: 07/26/2024] [Indexed: 08/19/2024] Open
Abstract
This study aimed to elucidate the molecular mechanisms underlying the therapeutic effects of Cangzhu Erchen decoction (CZECD) in the treatment of chronic obstructive pulmonary disease (COPD) using microarray analysis, network pharmacology, and molecular docking. The active components and candidate targets of CZECD were obtained using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform and Swiss Target Prediction. COPD-related targets were collected from 5 databases. Access to drug-disease interface targets in the Venny platform. The Cytoscape program and the STRING database were used for protein-protein interaction analysis and subsequent core target screening. The DAVID database was used for Gene Ontology (GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes enrichment pathway analysis, while AutoDockTools was used for molecular docking to confirm binding affinity between drugs and key targets. A total of 140 compounds from CZECD and 5100 COPD-related targets were identified. SRC, PIK3CA, STAT3, PIK3R1, AKT1, HSP90AA1, PIK3CB, GRB2, PIK3CD, and MAPK1 were identified as the major targets of CZECD in its anti-COPD activity. GO and Kyoto Encyclopedia of Genes and Genomes enrichment studies revealed that CZECD mainly affects biological processes such as protein phosphorylation, xenobiotic response, positive regulation of the MAPK cascade, and inflammatory responses. Cancer, PI3K/AKT, and MAPK were the key pathways mediating these effects. The positive association between the core targets and the compounds was further validated by molecular docking. CZECD exerts its therapeutic role in COPD mainly through multiple compounds, targets, and pathways.

Abstract
Background Jinshuibao capsules has been utilized in treating stable chronic obstructive pulmonary disease (COPD) for a long time. While the evidence-based evidence and network pharmacology to clarify the therapeutic efficacy and pharmacological mechanisms of Jinshuibao capsules have remained elusive. Objectives Integrating evidence-based medicine and network pharmacology to explain the therapeutic efficacy and pharmacological mechanisms of Jinshuibao capsules for stable COPD. Methods Cochrane Library, Web of Science, EMBASE, PubMed, China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, VIP Information Resource Integration Service Platform (CQVIP), and China Biomedicine (SinoMed) databases were searched. Studies were selected according to the inclusion and exclusion criteria. Statistical analysis was performed using the RevMan 5.3 software (Cochrane, London, UK). In network pharmacology, components of Jinshuibao capsules were screened, stable COPD-related genes were then identified and the 'component-target-pathway' network constructed. Results Meta-analysis revealed that Jinshuibao capsules exerts therapeutic effects on stable COPD by increasing the levels of FEV1% pred, FEV1/FVC ratio, FEV1, FVC, and PaO2 while decreasing the level of PaCO2. In addition, Jinshuibao capsules could effectively increase the levels of CD3+, CD4+/CD8+ ratio, Th17/Treg ratio, and SOD while reduce the levels of IL-8 and TNF-α. Network pharmacology identified 22 active compounds and 419 intersection gene targets. AKT1, SRC, MAPK1, STAT3, and MAPK3 were top 5 key target proteins. Besides, 20 potential pathways of Jinshuibao capsules on stable COPD were identified, like endocrine resistance, AGE-RAGE signaling pathway in diabetic complications, and chemical carcinogenesis-receptor activation. Conclusion Jinshuibao capsules could positively influence patients with stable COPD, while the efficacy and safety of Jinshuibao capsules in the treatment of COPD could not be reliably confirmed. These findings suggest that Jinshuibao capsules exerts effect on stable COPD through multi-target, multi-component and multi-pathway mechanism. Future studies may explore the active components of Jinshuibao capsules.

An open-label pilot study of losmapimod to evaluate the safety, tolerability, and changes in biomarker and clinical outcome assessments in participants with facioscapulohumeral muscular dystrophy type 1. J Neurol Sci 2024; 462:123096. [PMID: 38959779 DOI: 10.1016/j.jns.2024.123096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Revised: 06/05/2024] [Accepted: 06/12/2024] [Indexed: 07/05/2024]
Abstract
INTRODUCTION Facioscapulohumeral muscular dystrophy (FSHD) is a genetic disease caused by aberrant DUX4 expression, leading to progressive muscle weakness. No effective pharmaceutical treatment is available. Losmapimod, a small molecule selective inhibitor of p38 α/β MAPK, showed promising results in a phase 1 trial for the treatment of FSHD, prompting additional studies. We report the findings of an open-label phase 2 trial (NCT04004000) investigating the safety, tolerability, pharmacokinetics, pharmacodynamics, and exploratory efficacy of losmapimod in participants with FSHD1. METHODS This study was conducted at a single site in the Netherlands from August 2019 to March 2021, with an optional, ongoing open-label extension. Participants aged 18 to 65 years with FSHD1 took 15 mg of losmapimod twice daily for 52 weeks. Primary endpoints were measures of losmapimod safety and tolerability. Secondary endpoints were assessments of losmapimod pharmacokinetics and pharmacodynamics. RESULTS Fourteen participants were enrolled. No deaths, serious treatment-emergent adverse events (TEAEs), or discontinuations due to TEAEs were reported. Losmapimod achieved blood concentrations and target engagements that were previously associated with decreased DUX4 expression in vitro. Clinical outcome measures showed a trend toward stabilization or improvement. CONCLUSIONS Losmapimod was well tolerated and may be a promising new treatment for FSHD; a larger phase 3 study is ongoing.

Abstract
Albumin has a variety of biological functions, such as immunomodulatory and antioxidant activity, which depends largely on its thiol activity. However, in clinical trials, the treatment of albumin by injection of commercial human serum albumin (HSA) did not achieve the desired results. Here, we constructed reduced modified albumin (SH-Alb) for in vivo and in vitro experiments to investigate the reasons why HSA did not achieve the expected effects. SH-Alb was found to delay the progression of liver fibrosis in mice by alleviating liver inflammation and oxidative stress. Although R-Alb also has some of the above roles, the effect of SH-Alb is more remarkable. Mechanism studies have shown that SH-Alb reduces the release of pro-inflammatory and pro-fibrotic cytokine through the mitogen-activated protein kinase (MAPK) signaling pathway. In addition, SH-Alb deacetylates SOD2, a key enzyme of mitochondrial reactive oxygen species (ROS) production, by promoting the expression of SIRT3, thereby reducing the accumulation of ROS. Finally, macrophages altered by R-Alb or SH-Alb can inhibit the activation of hepatic stellate cells and endothelial cells, further delaying the progression of liver fibrosis. These results indicate that SH-Alb can remodel the phenotype of macrophages, thereby affecting the intrahepatic microenvironment and delaying the process of liver fibrosis. It provides a good foundation for the application of albumin in clinical treatment.

[PMID: 38730482 PMCID: PMC11084090 DOI: 10.1186/s12964-024-01627-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Accepted: 04/21/2024] [Indexed: 05/12/2024] Open
Abstract
BACKGROUND Helicobacter pylori (H. pylori) is the predominant etiological agent of gastritis and disrupts the integrity of the gastric mucosal barrier through various pathogenic mechanisms. After H. pylori invades the gastric mucosa, it interacts with immune cells in the lamina propria. Macrophages are central players in the inflammatory response, and H. pylori stimulates them to secrete a variety of inflammatory factors, leading to the chronic damage of the gastric mucosa. Therefore, the study aims to explore the mechanism of gastric mucosal injury caused by inflammatory factors secreted by macrophages, which may provide a new mechanism for the development of H. pylori-related gastritis. METHODS The expression and secretion of CCL3 from H. pylori infected macrophages were detected by RT-qPCR, Western blot and ELISA. The effect of H. pylori-infected macrophage culture medium and CCL3 on gastric epithelial cells tight junctions were analyzed by Western blot, immunofluorescence and transepithelial electrical resistance. EdU and apoptotic flow cytometry assays were used to detect cell proliferation and apoptosis levels. Dual-luciferase reporter assays and chromatin immunoprecipitation assays were used to study CCL3 transcription factors. Finally, gastric mucosal tissue inflammation and CCL3 expression were analyzed by hematoxylin and eosin staining and immunohistochemistry. RESULTS After H. pylori infection, CCL3 expressed and secreted from macrophages were increased. H. pylori-infected macrophage culture medium and CCL3 disrupted gastric epithelial cells tight junctions, while CCL3 neutralizing antibody and receptor inhibitor of CCL3 improved the disruption of tight junctions between cells. In addition, H. pylori-infected macrophage culture medium and CCL3 recombinant proteins stimulated P38 phosphorylation, and P38 phosphorylation inhibitor improved the disruption of tight junctions between cells. Besides, it was identified that STAT1 was a transcription factor of CCL3 and H. pylori stimulated macrophage to secret CCL3 through the JAK1-STAT1 pathway. Finally, after mice were injected with murine CCL3 recombinant protein, the gastric mucosal injury and inflammation were aggravated, and the phosphorylation level of P38 was increased. CONCLUSIONS In summary, our findings demonstrate that H. pylori infection stimulates macrophages to secrete CCL3 via the JAK1-STAT1 pathway. Subsequently, CCL3 damages gastric epithelial tight junctions through the phosphorylation of P38. This may be a novel mechanism of gastric mucosal injury in H. pylori-associated gastritis.

Abstract
Purpose Investigate the efficacy of blood microRNAs (miRNAs) as diagnostic biomarkers for Chronic Obstructive Pulmonary Disease (COPD). Patients and Methods We conducted a comprehensive search in English and Chinese databases, selecting studies based on predetermined criteria. Diagnostic parameters like summarized sensitivity (SSEN), summarized specificity (SSPE), summarized positive likelihood ratio (SPLR), summarized negative likelihood ratio (SNLR), and diagnostic odds ratio (DOR), and area under the curve (AUC) of the summary receiver operating characteristic (SROC) curves were analyzed using a bivariate model. Each parameter was accompanied by a 95% confidence interval (CI). Results Eighteen high-quality studies were included. For diagnosing COPD with blood miRNAs, the SSEN was 0.83 (95% CI 0.76-0.89), SSPE 0.76 (95% CI 0.70-0.82), SPLR 3.50 (95% CI 2.66-4.60), SNLR 0.22 (95% CI 0.15-0.33), DOR 15.72 (95% CI 8.58-28.77), and AUC 0.86 (95% CI 0.82-0.88). In acute exacerbations, SSEN was 0.85 (95% CI 0.76-0.91), SSPE 0.80 (95% CI 0.73-0.86), SPLR 4.26 (95% CI 3.05-5.95), SNLR 0.19 (95% CI 0.12-0.30), DOR 22.29 (95% CI 11.47-43.33), and AUC 0.89 (95% CI 0.86-0.91). Conclusion Blood miRNAs demonstrate significant accuracy in diagnosing COPD, both in general and during acute exacerbations, suggesting their potential as reliable biomarkers.

Abstract
Polysaccharides are biomolecules composed of monosaccharides that are widely found in animals, plants and microorganisms and are of interest for their various health benefits. Cumulative studies have shown that the modulation of radiation-induced apoptosis by polysaccharides can be effective in preventing and treating a wide range of radiation injuries with safety and few side effects. Therefore, this paper summarizes the monosaccharide compositions, molecular weights, and structure-activity relationships of natural polysaccharides that regulate radiation-induced apoptosis, and also reviews the molecular mechanisms by which these polysaccharides modulate radiation-induced apoptosis, primarily focusing on promoting cancer cell apoptosis to enhance radiotherapy efficacy, reducing radiation damage to normal tissues, and inhibiting apoptosis in normal cells. Additionally, the role of gut microbiota in mediating the interaction between polysaccharides and radiation is discussed, providing innovative ideas for various radiation injuries, including hematopoiesis, immunity, and organ damage. This review will contribute to a better understanding of the value of natural polysaccharides in the field of radiation and provide guidance for the development of natural radioprotective agents and radiosensitizers.

Abstract
BACKGROUND Currently, the primary treatment for gastroesophageal reflux is acid suppression with proton pump inhibitors, but they are not a cure, and some patients don't respond well or refuse long-term use. Therefore, alternative therapies are needed to understand the disease and develop better treatments. Laparoscopic anti-reflux surgery (LARS) can resolve symptoms of these patients and plays a significant role in evaluating esophageal healing after preventing harmful effects. Successful LARS improves typical gastroesophageal reflux symptoms in most patients, mainly by reducing the exposure time to gastric contents in the esophagus. Amelioration of the inflammatory response and a recovery response in the esophageal epithelium is expected following the cessation of the noxious attack. AIM To explore the role of inflammatory biomolecules in LARS and assess the time required for esophageal epithelial recovery. METHODS Of 22 patients with LARS (pre- and post/5.8 ± 3.8 months after LARS) and 25 healthy controls (HCs) were included. All subjects underwent 24-h multichannel intraluminal impedance-pH monitoring and upper gastrointestinal endoscopy, during which esophageal biopsy samples were collected using endoscopic techniques. Inflammatory molecules in esophageal biopsies were investigated by reverse transcription-polymerase chain reaction and multiplex-enzyme-linked immunosorbent assay. RESULTS Post-LARS samples showed significant increases in proinflammatory cytokines [interleukin (IL)-1β, interferon-γ, C-X-C chemokine ligand 2 (CXCL2)], anti-inflammatory cytokines [CC chemokine ligand (CCL) 11, CCL13, CCL17, CCL26, CCL1, CCL7, CCL8, CCL24, IL-4, IL-10], and homeostatic cytokines (CCL27, CCL20, CCL19, CCL23, CCL25, CXCL12, migration inhibitory factor) compared to both HCs and pre-LARS samples. CCL17 and CCL21 levels were higher in pre-LARS than in HCs (P < 0.05). The mRNA expression levels of AKT1, fibroblast growth factor 2, HRAS, and mitogen-activated protein kinase 4 were significantly decreased post-LARS vs pre-LARS. CCL2 and epidermal growth factor gene levels were significantly increased in the pre-LARS compared to the HCs (P < 0.05). CONCLUSION The presence of proinflammatory proteins post-LARS suggests ongoing inflammation in the epithelium. Elevated homeostatic cytokine levels indicate cell balance is maintained for about 6 months after LARS. The anti-inflammatory response post-LARS shows suppression of inflammatory damage and ongoing postoperative recovery.

Abstract
Central neurological disorders are significant contributors to morbidity, mortality, and long-term disability globally in modern society. These encompass neurodegenerative diseases, ischemic brain diseases, traumatic brain injury, epilepsy, depression, and more. The involved pathogenesis is notably intricate and diverse. Ferroptosis and neuroinflammation play pivotal roles in elucidating the causes of cognitive impairment stemming from these diseases. Given the concurrent occurrence of ferroptosis and neuroinflammation due to metabolic shifts such as iron and ROS, as well as their critical roles in central nervous disorders, the investigation into the co-regulatory mechanism of ferroptosis and neuroinflammation has emerged as a prominent area of research. This paper delves into the mechanisms of ferroptosis and neuroinflammation in central nervous disorders, along with their interrelationship. It specifically emphasizes the core molecules within the shared pathways governing ferroptosis and neuroinflammation, including SIRT1, Nrf2, NF-κB, Cox-2, iNOS/NO·, and how different immune cells and structures contribute to cognitive dysfunction through these mechanisms. Researchers' findings suggest that ferroptosis and neuroinflammation mutually promote each other and may represent key factors in the progression of central neurological disorders. A deeper comprehension of the common pathway between cellular ferroptosis and neuroinflammation holds promise for improving symptoms and prognosis related to central neurological disorders.
