Identification of hub genes and key miRNAs associated with oxidative stress in radiation-induced lung injury via RNA sequencing and bioinformatics analysis

ABSTRACT: In this study, through X-ray irradiation and RNA sequencing of human bronchial epithelial BEAS-2B cells, central genes and enrichment pathways related to oxidative stress of radiation lung injury were found, and the potential molecular mechanism of RILI was elucidated.The GO function annotation and KEGG pathway enrichment analysis of candidate genes were performed using David database.The STRING database and Cytoscape platform were used to construct PPI network diagram.The result was 421 DEGs.The candidate genes (158 up-regulated genes and 101 down-regulated genes) enriched 289 GO terms and 38 KEGG pathways.The top 10 pivot genes and the top 3 key miRNAs were found by constructing the network map.In summary, we identified central genes, key miRNAs and enrichment pathways related to oxidative stress, as well as the potential molecular mechanisms of RILI.These results provide new ideas for elucidating the potential molecular mechanism of RILI and identifying new targets and new approaches for prevention and control of RILI.

Gene expression during CCK-induced damaged pancreatic acinar cells with or without the addition of OCA

Project description:Obeticholic acid (OCA) has shown pharmacological protection activity in acinar cell injury and pancreatic necrosis in vitro. RNA sequencing was performed by extracting mRNA from CCK-induced damaged pancreatic acinar cells with or without the addition of OCA. Gene enrichment analysis by Kyoto Encyclopedia of Genes and Genomes (KEGG) identified oxidative phosphorylation in the top ten significantly changed pathways. Similarly, Gene Set Enrichment Analysis (GSEA) enrichment analysis revealed clear alterations in "mitochondrial ATP synthesis coupled electron transport", "mitochondrial respiratory chain complex assembly", "NADH dehydrogenase complex assembly", and "oxidative phosphorylation".

Exploring the Impact of m6A Methyltransferase Mettl3 on MASLD through Multi-Omics Analysis

Project description:Background: N6-methyladenosine (m6A) RNA modification plays a crucial role in various biological events and is implicated in various metabolic-related diseases. However, its role in MASLD remains unclear. This study aims to investigate the impact of Mettl3 on MASLD through multi-omics analysis, with a focus on exploring its potential mechanisms of action. Methods: MASLD mouse models were established by feeding a high-fat diet for 12 weeks, and Mettl3 stable overexpression AML12 cell models were constructed via lentiviral transfection. Subsequent transcriptomic and proteomic analyses, as well as integrated analysis between different omics datasets, were conducted. Results: Mettl3 expression significantly increased in MASLD mouse models. In the transcriptomic and proteomic analyses, we identified 848 genes with significant inconsistencies between transcriptomic and proteomic datasets. GO/KEGG enrichment terms may involve post-transcriptional modifications, particularly Mettl3-mediated m6A modification. Subsequently, through integrated proteomic analysis of Mettl3-overexpressed AML12 cell models and MASLD mouse models, we selected the top 20 co-upregulated and co-downregulated GO/KEGG terms as the main biological processes influenced by Mettl3 in MASLD. By intersecting with pathways obtained from previous integrated analyses, we identified GO/KEGG terms affected by Mettl3-induced m6A modification. Protein-protein interaction analysis of proteins involved in these pathways highlighted GAPDH, ENO1, and TPI1 as three key hub genes. Conclusion: In MASLD, Mettl3 regulates the glycolytic pathway through m6A modification, influencing the occurrence and development of the disease via the key hub genes GAPDH, ENO1, and TPI1. These findings expand our understanding of MASLD and provide strong evidence for potential therapeutic targets and drug development.

Targeted experimentation to increase functional coverage in omics dataset

Project description:To increase the GO coverage of Ecomics, we investigated which new conditions would lead to the most informative transcriptional profiles. We first transcriptionally profiled and included in the compendium 9 KO experiments that we had identified before as being highly informative for both GO coverage and model performance. We assumed that a GO term is represented in the compendium if the compendium has profiles where one or more genes that include that GO term have been perturbed. We identified the gene rank iteratively under the assumption that all genes of higher rank have been perturbed. Based on the resulting ranked list, we performed transcriptional profiling for the top 16 genetic perturbations (in triplicate; 48 profiles total), which led to an increase in coverage by 19.8% for KEGG, 24.3% for BP and 63.9% for MF. Genome-wide expression profiling of 25 single-gene knockouts for BW25113 and its wild-type grown with either LB or M9 media supplemented with glucose (total 87 samples).

Transcriptomic changes in bovine skeletal muscle cells after resveratrol treatment

Project description:Resveratrol (RSV) has been confirmed to benefit human health. Resveratrol supplemented in the feeds of animals improved pork, chicken, and duck meat qualities. In this study, we identified differentially expressed (DE) messenger RNAs (mRNAs) (n = 3,856) and microRNAs (miRNAs) (n = 93) for the weighted gene co-expression network analysis (WGCNA) to investigate the co-expressed DE mRNAs and DE miRNAs in the primary bovine myoblasts after RSV treatment. The mRNA results indicated that RSV treatments had high correlations with turquoise module (0.91, P-value = 0.01) and blue module (0.93, P-value < 0.01), while only the turquoise module (0.96, P-value < 0.01) was highly correlated with the treatment status using miRNA data. After biological enrichment analysis, the 2,579 DE genes in the turquoise module were significantly enriched in the Gene Ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. The top two GO terms were actin filament-based process (GO:0030029) and actin cytoskeleton organization (GO:0030036). The top two KEGG pathways were regulation of actin cytoskeleton (bta04810) and tight junction (bta04530). Then, we constructed the DE mRNA co-expression and DE miRNA co-expression networks in the turquoise module and the mRNA–miRNA targeting networks based on their co-expressions in the key module. In summary, the RSV-induced miRNAs participated in the co-expression networks that could affect mRNA expressions to regulate the primary myoblast differentiation. Our study provided a better understanding of the roles of RSV in inducing miRNA and of the characteristics of DE miRNAs in the key co-expressed module in regulation of mRNAs and revealed new candidate regulatory miRNAs and genes for the beef quality traits.

RNA sequencing analysis of lung samples of control and irradiated animals

Project description:Purpose: Radiation-induced lung injury (RILI) is a progressive condition, with an early phase, radiation pneumonitis (RP), and a late phase, lung fibrosis (LF). RILI may occur after partial body ionizing radiation exposures or by internal radioisotope exposure, with wide individual variability in timing and extent of lung injury. This study aims to provide new insights into the pathogenesis and progression of RILI in the non-human primate (NHP) rhesus macaque model. Methods:We used an integrative approach to understand RILI and its evolution at clinical and molecular levels in seventeen NHPs exposed to10 Gy of whole thorax irradiation in comparison to three sham-irradiated control NHPs. Lung samples were collected at necropsy for molecular and histopathological analyses using RNA sequencing and immunohistochemistry Results: Our data enhances understanding of RILI in non-survivors and survivors in a NHP model. RNA sequencing highlighted the role of SERPINA3, ATP12A, GJB2, CLDN10, TOX3, LPA as possible biomarkers and potential therapeutic targets of RILI. Their differential expression in nonsurvivors and survivors correlated with the severity of the disease.
