Base excision repair is the major mechanism for repair of DNA base damage by reactive oxygen species but recent evidence indicate that nucleotide excision repair proteins, that are mutated in human syndromes, are involved too. The mechanisms of repair dealing with the direct oxidation of DNA will ...
(RTEs). Genetic elements abundant in mammalian genomes that move throughout the genome by a copy–paste mechanism involving reverse transcription and may accumulate in the cytoplasm, triggering inflammation. Sterile inflammation Inflammation arising in the absence of a pathogen or external inflammatory st...

Although miRNAs can epigenetically regulate DNA repair gene expression, the expression levels of many miRNAs may themselves be subject to epigenetic regulation. One mechanism of epigenetic regulation of miRNA expression is hypomethylation of the promoter region of the DNA sequence that codes for the ...
Gap endonuclease I (GEN1) is a cytosolic protein that can bind to Holliday junctions upon breakdown of the nuclear envelope during cell division. Previous studies have shown that GEN1 forms dimers to cleave Holliday junctions, but the exact mechanism by which it ensures the full resolution of Hol...
Fig. 1.A. Mechanism of DNA mismatch repair (MMR). There are five key MMR proteins in mammalian cells including MSH2, MSH3, MSH6, MLH1, and PMS2. These proteins form heterodimer complexes to recognize and correct erroneous insertion, deletion, and misincorporation of bases that arise during ...
