OGG1 activity might be inhibited during postreplicative mismatch repair.
Results show ogg1 is fundamentally required for protecting the developing brain, which may be helpful in understanding the aetiology of congenital brain deficits.
work demonstrates the requirement of ogg1 in cardiac progenitors and heart development in zebrafish
Arabidopsis cells use both FPG and OGG1 to repair 8-oxoG in a pathway that requires ZDP and ARP (show ARFRP1 Proteins) in downstream steps.
Overexpression of OGG1 enhances seed longevity and abiotic stress tolerance.
Overexpressed beta-OGG1 has the same role as alpha-OGG1 in protecting bronchial epithelial cells from apoptosis and mitochondrial dysfunction. Additionally, knocking down OGG1 enhanced oxidative damage-induced apoptosis and mitochondrial dysfunction. The antiapoptotic function of beta-OGG1 involved the JNK (show MAPK8 Proteins) signaling pathway.
The rs2304277 variant in the OGG1 glycosidase gene associated to a significant OGG1 transcriptional down regulation independently of the BRCA mutational status and this variant may exert a synergistic effect together with BRCA1 or BRCA2 (show BRCA2 Proteins) mutations in ovarian cancer
OGG1 can initiate BER at positions off the dyad axis and that this activity is facilitated by spontaneous and transient unwrapping of DNA from the histones. Local nuances in the nucleosome environment and histone-DNA interactions can impact glycosylase activity.
8-oxoguanine DNA glycosylase-1 (OGG1) is the essential protein involved in oxidative stress-induced (show SQSTM1 Proteins) DNA demethylation.
The allele combination of CGC from hOGG1, ITGA2 (show ITGA2 Proteins) and XPD (show ERCC2 Proteins) polymorphisms was significantly associated with increased odds of nasopharyngeal carcinoma.
Increased oxidative DNA damage in primary open angle glaucoma may be attributed to decreased expression of DNA repair enzymes, OGG1 and PARP1 (show PARP1 Proteins), of the base excision repair pathway.
Results show that some polymorphic variants in XRCC1 (show XRCC1 Proteins) and OGG1 are associated with increased DNA damage in Alzheimer's Disease.
The excision of the 8-oxoguanine base with DeltaG# = 16.1 kcal/mol (show DUOXA1 Proteins) proceeded via substitution of the C1-N9 N-glycosidic bond with an H-N9 bond where the negative charge on the oxoG base and the positive charge on the ribose were compensated in a concerted manner by NH3+(Lys249) and CO2-(Asp268), respectively.
The interaction of OGG1 and XRCC1 (show XRCC1 Proteins) DNA repair polymorphisms and arsenic exposure enhances telomeric DNA damage.
Polymorphisms of OGG1 and MTHFR (show MTHFR Proteins) genes are associated with ARC (show NOL3 Proteins) susceptibility
OGG1 plays a role in an LSD1 (show KDM1A Proteins)-dependent pathway of LPS (show TLR4 Proteins)-induced macrophage activation in mice.
These findings demonstrate that OGG-1 negatively regulates inflammatory cytokine release by coordinating molecular interaction with the autophagic pathway in hyperoxia-induced lung injury.
These results together, points to a new paradigm about the role of DNA damage and repair by OGG1 in aging and age-associated disease processes.
results implicate hyperglycemia-induced O-GlcNAcylation of Ogg1 in increased mtDNA damage and, therefore, provide a new plausible biochemical mechanism for diabetic cardiomyopathy.
DNA repair protein (show ATRIP Proteins) OGG1 bound to its substrate is coupled to DNA occupancy of NF-kappaB (show NFKB1 Proteins) and functions in epigenetic regulation of gene expression.
OGG1 plays a protective role in atherosclerosis by preventing excessive inflammasome activation.
OGG1 acts as a STAT1 (show STAT1 Proteins) coactivator and has transcriptional activity in the presence of endotoxin
Ogg1 and Mutyh (show MUTYH Proteins) regulate hippocampal gene expression related to cognition and behavior, suggesting a role for the glycosylases in regulating adaptive behavior.
Data suggest that OGG1 plays a vital role in the protection of DNA bases from oxidative damage induced by radiofrequency electromagnetic radiation.
This gene encodes the enzyme responsible for the excision of 8-oxoguanine, a mutagenic base byproduct which occurs as a result of exposure to reactive oxygen. The action of this enzyme includes lyase activity for chain cleavage. Alternative splicing of the C-terminal region of this gene classifies splice variants into two major groups, type 1 and type 2, depending on the last exon of the sequence. Type 1 alternative splice variants end with exon 7 and type 2 end with exon 8. All variants share the N-terminal region in common, which contains a mitochondrial targeting signal that is essential for mitochondrial localization. Many alternative splice variants for this gene have been described, but the full-length nature for every variant has not been determined.
