Project description:Balbc J mouse received vehicle (solvent) or OGG1 inhibitor 1 h prior to treatment via intraperitoneal route. Tumor necrosis factor alpha (TNFa, 20 ng per ml) was installed into lungs via intranasal route in 60 microliters of solvent). One hour after TNFa challenge mice were sacrificed, lungs were removed and RNAs were isolated from individual lungs (n=6) After reverse transcription cDNAs were pooled and changes in gene expression was determined by using SABiosciences Mouse Inflammatory Cytokines & Receptors PCR Array (PAMM-011Z)

Project description:Respiratory syncytial virus (RSV), along with other prominent respiratory RNA viruses such as influenza and SARS-CoV-2, significantly contributes to the global incidence of respiratory tract infections. These pathogens induce the production of reactive oxygen species (ROS), which play a crucial role in the onset and progression of respiratory diseases. However, the mechanisms by which viral RNA manages ROS-induced base oxidation remain poorly understood. Here we reveal that 8-oxo-7,8-dihydroguanine (8-oxoGua) is not merely an incidental byproduct of ROS activity but serves as a strategic adaptation of RSV RNA to maintain genetic fidelity within host cells. Through 8-oxoguanine DNA glycosylase 1 (OGG1) immunoprecipitation and LC_MS/MS, we discovered that RSV nucleoprotein is a principal partner of OGG1. Further investigation revealed that viral ribonucleoprotein complexes specifically hijack OGG1. Importantly, inhibiting OGG1's ability to recognize 8-oxoGua significantly reduces RSV progeny production. Our results underscore the viral replication machinery's adaptation to oxidative challenges, suggesting that inhibiting OGG1's reading function could be a novel strategy for antiviral intervention.

Project description:To investigate the role of 8-oxo-7, 8-dihydroguanine (8-oxoguanine) accumulation in DNA or nucleotide pools during the development of AD pathology, we introduced a Mth1/Ogg1-double deficiency into homozygous triple-transgenic AD model (3xTg-AD-H) mice. Mth1 encodes 8-oxo-7, 8-dihydro-2'-deoxyguanosine-5'-triphosphatase (8-oxo-dGTPase) and Ogg1 encodes 8-oxoguanine DNA glycosylase 1. One-way eBays ANOVA of microarray data from hippocampi revealed that the gene expression profiles are most significantly altered in the hippocampi of 3xTg-AD-H with Mth1/Ogg1-double deficient (ADH/TO-DKH) mice compared to non-Tg control (NT) mice. Comparative analysis between 3xTg-AD-H (ADH/WT) and ADH/TO-DKH mice showed that the expression of genes involved in neuroprotection are significantly altered. Among them, expression of the AD-related genes including Ttr, Enpp2, Kcnj13 and Kl was significantly downregulated in ADH/TO-DKH mice.

Project description:We report the application of ChIP-Sequencing for profiling genome-wide distribution of 8-oxoguanine DNA glycosylase (OGG1) which is a DNA base excision repair protein, after TNF exposure of cells. By obtaining an average of over 18 million of total reads per sample and over 19.5 million of unique reads per sample from chromatin immunoprecipitated DNA, we generated genome-wide chromatin-state maps of HEK293 cells. We performed gene ontology and functional pathway analysis of genes associate with peaks, and identify regions of the genomes (e.g. promoter, introns, etc) where the peaks tend to occur. The results show that OGG1 is primarily associated with promoter regions in vicinity of transcription factor binding sites 5' of transcription start sites (TSS). This pattern of distribution occurs in spite of genome-wide oxidative modifications of guanine (primarily 8-oxoG). OGG1 increased highly significant (1e-09 to 1e-517) enrichment of 57 transcription factor binding sites including those for Sox(2, 3, 6, 10), RUNX, RUNX(1, 2), HOX(C, D), STAT(1, 3, 6), IRF(1 to 4), NF-κB. In controls, the DNA was chromatin immunoprecipitated using antibody to NF-κB/RelA. These and other data derived from further analysis, suggest that OGG1 modulates binding of transcription factors and gene expression.

These pathogens prompt the production of reactive oxygen species (ROS), which play a crucial role in the onset and progression of respiratory diseases.

Here we uncover that 8-oxo-7,8-dihydroguanine (8-oxoGua) is not merely an incidental byproduct of ROS activity but serves as a strategic adaptation of RSV RNA during replication within host cells. Through RNA immunoprecipitation and next-generation sequencing, we discovered that 8-oxoguanine DNA glycosylase 1 (OGG1) binding sites are predominantly found in the RSV antigenome, especially within guanine-rich areas. Further investigation revealed that viral ribonucleoprotein complexes specifically hijack OGG1. Crucially, our findings show that inhibiting OGG1's ability to recognize 8-oxoGua leads to a substantial reduction in RSV progeny production. Our results underscore the viral replication machinery's adaptation to oxidative challenges, pointing to the inhibition of OGG1's reading function as a potential novel strategy for antiviral intervention.

Project description:7,8-dihydro-8-oxoguanine (OG) is one of the major DNA oxidative damages, which has been concerned by researchers for its potential of mutagenesis and epigenetic regulation. Genome-wide mapping of oxidative DNA damage is of great value for understanding the biological impact of these modifications. Here we present a novel appoach to profile guanine oxidation in the mouse genome. Through structure-guided mutagenesis, we've successufully engineered 8-oxoguanine DNA glycosylase into a useful tool for OG detection. By enrichment of glycosylase-DNA complex, thousands of OG peaks were identified in the mouse genome.
