Transcriptome of Paraquat-induced Pulmonary Fibrosis

ABSTRACT: PURPOSE: Pulmonary fibrosis (PF) is a pathological state presenting at the progressive stage of heterogeneous interstitial lung disease (ILD). The molecular mechanisms are incompletely understood. We built a mouse model of lung fibrosis induced by paraquat. Using transcriptome analysis, we identified differentially expressed proteins (DEGs) and provided further functional analysis. METHODS: We built a mouse model of lung fibrosis through intratracheal instillation of paraquat. After instillation, mice were kept for 7 and 28 days, respectively. we performed time-series RNA sequencing (RNA-Seq) on the lung samples from paraquat treated mice and saline control. The DEGs were verified by qPCR. RESULTS: The transcriptome data found a total of 1345 of differentially expressed genes (DEGs) up-regulated and 844 DEGs down-regulated significantly in paraquat group on day 7. There were 511 DEGs up-regulated and 179 DEGs down-regulated remarkably on day 28 after PQ instillation (Fold Change ≥2 and Q value ≤0.001). We verified 6 significantly changed genes by qPCR, proving the accuracy of RNA-seq. CONCLUTION: Our transcriptomic study assigns genes for fibrogenesis and reveals their dynamic changes from lung injury to repair, providing new insights for the and development of biomarkers and treatment in fibrotic diseases.

Dose-dependent hepatic transcriptional responses in Atlantic salmon (Salmo salar) exposed to sublethal doses of gamma radiation

Project description:To study the short term (48 h) hepatic transcriptional changes and identify potential modes of action, Atlantic salmon (Salmo salar) were exposed to 15 mGy, 70 mGy and 280 mGy external gamma radiation. A combination of high density (60 k) custom oligonucleotide salmonid microarray and quantitative real-time reverse transcription polymerase chain reaction (qPCR) was employed to perform gene expression analyses. Differentially expressed genes (DEGs) were determined using one-way analysis of variance (ANOVA) and Tukey posthoc tests. Functional enrichment analysis based on Gene Ontology (GO) was performed to link DEGs to their biological functions. The Salmo salar DEGs were further mapped to mammlian orthologs. By using ortholog DEGs, gene networks were built based on well-curated mammlian protein-protein interactions and pathways analyses were performed to link DEGs to specific toxicological/biological functions. The results obtained from microarray analysis were further verified using qPCR. Juvenile Atlantic salmon were exposed to external gamma radiation emitted from a cobalt-60 source for 48 h. Liver were sampled and used for gene expression analysis.

Project description:To study the short term (48 h) hepatic transcriptional changes and identify potential modes of action, Atlantic salmon (Salmo salar) were exposed to 0.25 mg/L, 0.5 mg/L and 1.0 mg/L depleted uranium. A combination of high density (60 k) custom oligonucleotide salmonid miacroarray and quantitative real-time reverse transcription polymerase chain reaction (qPCR) was employed to perform gene expression analyses. Differentially expressed genes (DEGs) were determined using one-way analysis of variance (ANOVA) and Tukey posthoc tests. Functional enrichment analysis based on Gene Ontology (GO) was performed to link DEGs to their biological functions. The Salmo salar DEGs were further mapped to mammlian orthologs. By using ortholog DEGs, gene networks were built based on well-curated mammlian protein-protein interactions and pathways analyses were performed to link DEGs to specific toxicological/biological functions. The results obtained from microarray analysis were further verified using qPCR. Juvenile Atlantic salmon were exposed to waterborne depleted uranium for 48 h. Liver were samples and used for gene expression analysis.

long non-coding RNA expression profiles in Paraquat-induced pulmonary fibrosis

Project description:In this study, using the next generation transcriptome sequencing and microarray analysis, we profiled expression of long non-coding RNAs (lncRNAs) in a mouse model of paraquat-induced pulmonary fibrosis. We identified 513 up-regulated and 204 down-regulated lncRNAs (fold-change ≥5.0) when comparing fibrotic to normal lung tissues. Quantitative real-time PCR, Gene Ontology analysis, Pathway analysis and Bioinformatics analysis were performed for further research. Furthermore, we predicted and verified the target genes of two up-regulated lncRNAs, uc.77 and 2700086A05Rik, as Zeb2 and Hoxa3 respectively, both of which are important regulators of EMT.

Aberrant differentiation of epithelial progenitors is accompanied by a hypoxic microenvironment in the paraquat-injured human lung

Project description:Paraquat is a toxic herbicide that can cause severe lung injury, leading to alveolar epithelial cell death, subsequent lung fibrosis and respiratory failure. Understanding the repair process following paraquat injury is critical for developing effective therapeutic strategies to treat paraquat-poisoned patients. However, the lung repair program in paraquat-injured lungs is currently unknown. In this study, we analyzed lung parenchyma samples from an 18-year-old female patient who had ingested paraquat and subsequently underwent a double-lung transplantation on the 34th day after poisoning. By the combination of single cell RNA sequencing analysis and immunostaining analysis, we reveal that the airway stem/progenitor cells and AT2 cells in the paraquat-injured lung exhibit a significantly reduced capacity to regenerate alveolar epithelium epithelial in the paraquat-injured lung. The hypoxic microenvironment may contribute to this aberrant repair program by activating the NOTCH signaling pathway, ultimately leading to an irreversible loss of gas-exchange units and an exacerbated lung tissue damage.

Integrative Transcriptomic and Proteomic Analysis Reveals Mechanisms of Silica-induced Pulmonary Fibrosis in Rats

Project description:To explore proteomic and transcriptomic changes in rat model of silicosis, transcriptomic analysis by microarray and tandem mass tags (TMT)-based proteomic analysis were performed to reveal the expression of mRNAs and proteins in lung tissues. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were applied to analyze the alterated genes and proteins. The integrated analysis was performed between transcriptome and proteome. Furthermore, the data were further verified by RT-qPCR and parallel reaction monitoring (PRM). In total, 244 differentially expressed proteins (DEPs) showed the same trend as that of the corresponding differentially expressed genes (DEGs) (named DEPs/DEGs). GM2a, CHI3L1, LCN2 and GNAI1, which were validated consistently by RT-qPCR and PRM, are involved in the extracellular matrix (ECM) and inflammation contributed to fibrosis in silicosis.

Transcriptional profile of mouse lung during the fibrotic phase of the response to bleomycin

Project description:Wildtype mice were given saline or bleomycin by oropharyngeal instillation. After 14 days, during the fibrotic phase of the response, lungs were dissected and total RNA was extracted and used for gene expression profiling. The aim was to identify those genes regulated during the development of fibrosis in this animal model of bleomycin-induced lung fibrosis.

Proteomic profiling of young and old mice in the bleomycin model

Project description:The most preclinical used in vivo model to study lung fibrosis is the bleomycin-induced lung fibrosis model in 2-3-month-old mice. Although this model resembles key aspects of idiopathic pulmonary fibrosis (IPF), there are limitations in its predictability for the human disease. One of the main differences is the juvenile age of animals that are usually used in experiments, resembling humans of around 20 years. Because IPF patients are usually older than 60 years, aging appears to play an important role in the pathogenesis of lung fibrosis. We here compared young (3 months) and old (21 months) mice 21 days after intratracheal bleomycin instillation.
