8-oxoG RNA IP data set 2: Air pollution mixture derived from the reaction of 100 ppb acrolein, 97 ppb methacrolein, 44 ppb alpha-pinene and 100 ppb O3 for 1.5 h

Project description:While environmental agents such as air pollution have been shown to be causative to diseases, yet limited knowledge exist on their mechanism of action. Here we used RNA-sequencing in combination with specific immunoprecipitation of 8-oxo-7,8-dihydroguanosine (8-oxoG) to identify transcripts accumulating oxidation after exposure to air pollution (derived from the reaction of acrolein, methacrolein, alpha-pinene and ozone) in bronchial epithelial BEAS-2B cells. Results from this analysis suggest a functional role of the 8-oxoG modified transcripts after air pollution exposure in pathways that are central regulators of cell metabolism, growth, proliferation and maintenance of cellular structure. This study highlights a critical role for a RNA epitranscriptomics modification that can be used to further characterize biological responses to external stressors once considered indistinguishable.

Acrolein-mediated changes in HUVEC miRNA

Project description:Acrolein is a major reactive component of vehicle exhaust, cigarette and wood smoke. It is also present in several food substances and is generated endogenously during inflammation and lipid peroxidation. Although previous studies have shown that dietary or inhalation exposure to acrolein results in endothelial activation, platelet activation and accelerated atherogenesis, the basis for these effects is unknown. Moreover, the effects of acrolein on microRNA (miRNA) have not been studied. Using AGILENT miRNA microarray high throughput technology, we have thus characterized the effects of acrolein exposure on miRNA expression in human umbilical vein endothelial cells (HUVEC).

Acrolein-induced transcriptomic alterations in male Wistar-Kyoto rats

Project description:Acute acrolein inhalation in male rats resulted in multi-tissue transcriptomic alterations that were observed through Illumina mRNA sequencing. Specifically, site-specific respiratory expression profile differences were noted between air- and acrolein-exposed groups. Nasal epithelial tissue demonstrated 452 differentially expressed genes (DEGs) (310 up-regulated and 142 down-regulated)and lung tissue demonstrated 95 DEGs (80 up-regulated and 15 down-regulated). Notable transcriptomic alterations were also observed in liver tissue of acrolein-exposed rats, with 1699 identified DEGs (788 up-regulated and 911 down-regulated). A variety of mRNA expression profile differences resulting from acute acrolein inhalation was observed in other peripheral tissues, including adipose, muscle, adrenals, hippocamus, and hypothalamus. Gene changes were largely representative of oxidative and inflammatory response in the nose, as well as xenobiotic metabolism changes in the lung. Liver changes, which were most numerous, included alterated metabolic signaling (Sirtuin and FXR signaling), as well as alterated oxidoreductive, GPCR, and glucocorticoid pathways. Together, these data demonstrate acrolein, a well-characterized respiratory irritant, induces systemic neuroendocrine immunological and metabolic stress.

Next Generation Sequencing Facilitates Quantitative Analysis of Wildtype, akr1a1a-/- and Wildtype with Acrolein Treatment Zebrafish Larvae Transcriptomes

Project description:Our previous experiments showed the function of Akr1a1a was related to insulin resistance. The knockout of Akr1a1a led to poor acrolein detoxification and accumulated acrolein inhibits insulin receptors (insra/insrb) expression. To understand how the loss of Akr1a1a and acrolein reflects at the transcriptome level, we performed full genome RNA-Seq between akr1a1a+/+, akr1a1a-/- and akr1a1a+/+ with acrolein treatment zebrafish larvae at 120 hpf. An overview of RNA-Seq, including quality control, principal component analysis (PCA), and volcano plots of regulated genes showed comparable properties between akr1a1a mutants, wild type and acrolein treated wild type zebrafish larvae. We found the insulin receptor signaling pathway was down-regulated significantly in akr1a1a mutants and acrolein treated wild type larvae as compared to wild type larvae via gene set enrichment analysis (normalized enrichment score, -1.888, p=0.028; -1.93, p=0.019). Intriguingly, downstream signaling pathways including MAPK, signal transduction by protein phosphorylation and transmembrane receptor protein tyrosine kinase signaling pathway were also significantly down-regulated in akr1a1a mutants and acrolein treated wild type larvae. Taken together, these results further suggest akr1a1a and acrolein as an important regulator in insulin receptor signaling transduction. Furthermore, we offer a comprehensive and more detailed evaluation of mRNA content within zebrafish larvae. We conclude that RNA-seq based transcriptome would clearly illustrate genetic network and clarify complex biological functions.

Dysregulation of acrosome formation network by 8-oxoguanine (8-oxoG) in infertile sperm

Project description:Various environmental factors contribute to dysregulated spermatogenic gene network, abnormal spermatogenesis, and eventually impaired sperm fertility. 8-hydroxyguanine (8-oxoG) is the most common and well-studied oxidative DNA lesion of the four DNA bases and unrepaired 8-oxoG modifications are associated with DNA fragmentation in sperms. However, the molecular effects of 8-oxoG generated in sperm DNA by oxidative stress on spermatogenesis are not entirely understood. Here, we identified one infertile Korean native striped cattle at 6-year old (C14) due to asthenozoospermia and teratozoospermia. We compared global concentration of 8-oxoG by reverse-phase liquid chromatography/mass spectrometry (RP-LC/MS), the genomic distribution of 8-oxoG by next-generation sequencing (OG-seq), and expression of sperm proteins by 2-dimensional electrophoresis followed by mass spectrometry (2D/MS) in sperms of C14 with those of normal counterpart (C13). We found that averaged levels of 8-oxoG in C13 and C14 sperms were 0.027% and 0.044% of total dG and 8-oxoG was significantly greater in infertile sperm DNA (p = 0.0028). More than 81% of the 8-oxoG loci were distributed around the transcription start site (TSS) and 8-oxoG harboring 165 genes, including phospholipases, were annotated exclusively into infertile sperm DNA. Gene set enrichment analysis (GSEA) and the protein-protein interaction networking revealed that the Golgi apparatus was significantly enriched with the 8-oxoG genes of infertile sperm (q = 2.20E-07). Proteomic analysis verified that acrosome-related proteins including Acrosin-binding protein (ACRBP) and Sperm equatorial segment protein 1 (SPESP1) were 1.6-fold and 2.6-fold down-regulated in infertile sperm, respectively. These results suggest that 8-oxoG formation during spermatogenesis would dysregulate the acrosome-related gene network, causing structural and functional defects of sperm, leading to infertility.
