The DNA glycosylases Ogg1 and Nth1 do not contribute to Ig class switching in activated mouse splenic B cells. [PDF]
During activation of B cells to undergo class switching, B cell metabolism is increased, and levels of reactive oxygen species (ROS) are increased. ROS can oxidize DNA bases resulting in substrates for the DNA glycosylases Ogg1 and Nth1.

Synergistic Actions of Ogg1 and Mutyh DNA Glycosylases Modulate Anxiety-like Behavior in Mice
Ogg1 and Mutyh DNA glycosylases cooperate to prevent mutations caused by 8-oxoG, a major premutagenic DNA lesion associated with cognitive decline. We have examined behavior and cognitive function in mice deficient of these glycosylases.

The Kinetic Mechanism of 3′-5′ Exonucleolytic Activity of AP Endonuclease Nfo from E. coli
Escherichia coli apurinic/apyrimidinic (AP) endonuclease Nfo is one of the key participants in DNA repair. The principal biological role of this enzyme is the recognition and hydrolysis of AP sites, which arise in DNA either as a result of the ...

Differential Binding of NLRP3 to non-oxidized and Ox-mtDNA mediates NLRP3 Inflammasome Activation
The NLRP3 inflammasome is a key mediator of the innate immune response to sterile tissue injury and is involved in many chronic and acute diseases. Physically and chemically diverse agents activate the NLRP3 inflammasome.

The Base Excision Repair Pathway in the Nematode Caenorhabditis elegans
Exogenous and endogenous damage to the DNA is inevitable. Several DNA repair pathways including base excision, nucleotide excision, mismatch, homologous and non-homologous recombinations are conserved across all organisms to faithfully maintain the ...

Biogenesis of Iron–Sulfur Clusters and Their Role in DNA Metabolism
Iron–sulfur (Fe/S) clusters (ISCs) are redox-active protein cofactors that their synthesis, transfer, and insertion into target proteins require many components. Mitochondrial ISC assembly is the foundation of all cellular ISCs in eukaryotic cells.

This work presents new data on human endonuclease VIII-like 2 protein (hNEIL2), a part of DNA glycosylases of the helix–two-turn–helix structural superfamily. While X-ray structure of oNEIL2 (opossum Monodelphis) was resolved partially [1], the structure
