A label-free proteomics method to investigate the protective effect of Gu-Ben-Fang-Xiao in a chronic persistent murine asthma model

ABSTRACT: Ethnopharmacological relevance: Gubenfangxiao decoction (GBFXD) is a traditional Chinese medicine formula derived from Yupingfensan, an ancient formula widely used to treat respiratory diseases such as repeated respiratory infection, allergic rhinitis, bronchitis, and asthma. In recent years, GBFXD has been applied to efficaciously and safely treat asthma. However, the mechanism of GBFXD is still not fully elucidated. Aim of the study: A label-free proteomic method was to employed to explore the protective mechanism of GBFXD in respiratory syncytial virus (RSV)-ovalbumin (OVA)-induced chronic persistent asthmatic mice. Materials and methods: After RSV-OVA challenge, mice were orally administered GBFXD at a dose of 36 g/kg/d accompanied with OVA nasal spray once every 3 days for 28 days. The label-free proteomics-based liquid chromatography-tandem mass spectrometry method was used to explore the differentially abundant proteins (DAPs) in the serum from model mice compared with that in control mice (M:C), and in GBFXD-treated mice compared with that in model mice (G:M). We utilized OmicsBean (http://www.omicsbean.cn), a multi-omics data analysis platform, to perform bioinformatics analysis of DAPs. Enzyme-linked immunosorbent assay and Western Blotting were performed to measure the levels of related proteins and verify the results of proteomics analysis. Results: A total of 69 significant DAPs were identified including 39 in M:C, 46 in G:M, and 16 common differential proteins. Bioinformatics analysis revealed that the DAPs of M:C were mainly involved in inflammatory response and were related to lipid metabolism. However, the DAPs of G:M mostly participated in stress response, inflammatory response, and epithelial cell proliferation. Serum levels of Apoa-1, Apoc-1, Cfd, and Lrg1, EGFR and Lrg1 in the lungs were consistent with the results of proteomic analysis. Apoa-1 and Apoc-1 are closely related to cholesterol transport, lipid metabolism balance, and airway epithelial integrity; Cfd participates in immune response, affecting the occurrence and development of inflammation; EGFR and Lrg1 are involved in epithelial cell proliferation, influencing the process of airway remodeling. Conclusions: GBFXD may affect inflammatory and immune responses of asthma by regulating cholesterol transport and complement factor activation. Furthermore, it could repair damaged airway epithelium and avoid airway remodeling to prevent and treat asthma.

Project description:Murine Pulmonary Responses to Ambient Baltimore Particulate Matter: Genomic Analysis and Contribution to Airway Hyperresponsiveness; Asthma is a complex disease characterized by airway hyperresponsiveness (AHR) and chronic airway inflammation. Environmental factors such as ambient particulate matter (PM), a major air pollutant, has been demonstrated in epidemiological studies to contribute to asthma exacerbation and increased asthma prevalence. OBJECTIVE: We investigated the genomic and pathophysiological effects of Baltimore PM (median diameter 1.78 Âµm) in a murine model of asthma to identify potential biomarkers. METHODS: A/J mice with ovalbumin (OVA) âinduced AHR were exposed to PM (20 mg/kg, intratracheal), and both AHR and bronchoalveolar lavage (BAL) were assayed on days 1, 4, and 7 post exposure. Lung gene expression profiling (Affymetrix Mouse430_ 2.0) by PM (20 mg/kg, intratracheal) were assayed on OVA- and / or PM--challenged mice. RESULTS: Significant increases of airway responsiveness in OVA-treated mice were observed, indicating an asthmatic phenotype. Ambient PM exposure induced significant changes in AHR in both naive mice and OVA-induced asthmatic mice. In both naive and OVA challenged asthmatic mice, PM induced eosinophil and neutrophil infiltration into airways, elevated BAL protein content, and stimulated secretion of TH1 cytokines (IFN-g, IL-6, and TNF-a) and TH2 cytokines (IL-4, IL-5, and eotaxin) into BAL. Consistent with these results, PM induced expression of genes of innate immune response, chemotaxis and complementary system. CONCLUSION: These studies, consistent with epidemiological data, indicate that PM increases AHR and lung inflammation in naÃ¯ve mice and exacerbates the asthma phenotype of increased AHR and gene expression pattern changes correlated with acute lung inflammation and airway damage. We used microarrays to detail the global programme of gene expression induced by rhPBEF treatment and VALI. Experiment Overall Design: animals were treated by PBS, Oval albumin, PM, or both OVA/PM

Project description:Mechanisms by which regulatory T (Treg) cells fail to control inflammation in asthma remain poorly understood. We show that a severe asthma-associated polymorphism in the interleukin-4 receptor alpha chain (IL-4RÎ±-R576) biases induced Treg (iTreg) cells towards a T helper 17 (TH17) cell fate. This skewing reflects the recruitment by IL-4RÎ±-R576 of the adaptor protein growth factor receptor-bound protein 2 (GRB2), which drives IL-17 expression by an extracellular signal-regulated kinase-, IL-6- and STAT3-dependent mechanism. We showed that the IL-4RÎ±-R576 mutation elicits TH17 airway responses in vivo, in a house dust mite (HDM)- or ovalbumin (OVA)-driven model of airway inflammation in the mice carry the IL-4RÎ±-R576 mutation (Il4raR576 mice). Treg cell-specific deletion of genes encoding IL-6RÎ± or the master TH17 cell regulator Retinoid-related Orphan Receptor Î³t (RORÎ³t), but not IL-4 and IL-13, protected mice against exacerbated airway inflammation induced by IL-4RÎ±--576. Analysis of lung tissue Treg cells revealed that the expression of IL-17 and the TH17 cell-associated chemokine receptor CCR6 was largely overlapping and highly enriched in Treg and conventional T (Tconv) cells of allergen-treated Il4raR576 mice. To further characterize the subset of IL-17 producing Foxp3+ Treg in the lung of OVA-treated mice we utilized CCR6 as a marker of Treg cells committed towards the TH17 cell lineage to examine their functional, epigenetic and transcriptional profiles. CCR6+Foxp3EGFP+ Treg cells isolated from OVA-sensitized and challenged Il4raR576 mice, by FACS (Fluorescence Activated Cell Sorting) exhibited decreased methylation of the Foxp3 CNS2 locus comparing to CCR6âFoxp3EGFP+ Treg cells from same animals, indicative of decreased stability. They also exhibited profoundly decreased suppressive function as compared to CCR6â WT and CCR6â Il4raR576 counterparts. Transcriptional profiling of CCR6+Foxp3EGFP+ Treg cells revealed increased relative expression in CCR6+ Il4raR576 Treg cells of genes associated with a TH17 cell signature, including Rorc, Ccr6, Il23r, Il17a, Il17f, Il1r1, Nr1d1, Cstl, and Ahr comparing to CCR6âFoxp3EGFP+ Treg cells from same animals. Three CCR6+Foxp3EGFP+ Il4raR576 replicates and four CCR6âFoxp3EGFP+ Il4raR576 Treg replicates (controls) were sampled
