2024年11月21日 · In this study, we address this technological gap by presenting a detailed analysis of DSB repair factor localization in single cells. We use two methods to map DNA-binding proteins, namely...

DNA repair proteins, such as DNA-dependent protein kinase (DNA-PK), Ku, and ataxia-telangiectasia-mutated (ATM), have been linked to cellular DNA repair pathways that work to fix DNA DSBs, while ataxia-telangiectasia and Rad3-related (ATR) is activated by many forms of DNA damage. Ku70/80 and Artemis are involved in non-homologous end joining ...

2024年1月24日 · A database called DNArepairK tracks the kinetics of 70 fluorescently titled DNA repair proteins’ recruitment and clearance from complicated DNA damage sites in vivo in HeLa Kyoto cells.

As described previously, the major proteins involved with DNA repair include sensory (DNA binding) proteins, enzymes that remove damaged bases, and enzymes that restore the normal DNA sequence. A large number of regulatory enzymes also control each DNA repair pathway.

2022年2月4日 · We review the current knowledge of C. elegans DNA repair, recombination, and DNA damage response pathways, and their role during development, growth, and in the germ line. We also discuss how the analysis of mutational signatures in C. elegans is helping to inform cancer mutational signatures in humans.

2023年2月13日 · To preserve genomic integrity, cells have an arsenal of repair proteins that engage the appropriate repair pathway or, if damage is irreparable, induce cell cycle arrest and/or apoptosis.

1995年2月1日 · DNA repair proteins act to correct mutagenic and toxic DNA damage, which can lead to cancer, aging and death. These proteins and their mechanisms of action have been found to be widely conserved between species, often from bacteria to man.

2017年12月20日 · Here, we will describe the five main mechanisms by which DNA avoids mutation, namely the processes of base excision repair, mismatch repair, nucleotide excision repair, homologous recombination, and nonhomologous end joining.

Guarding genes against damage is a crucial and complex job, so it’s to be expected that cells have several mechanisms to repair DNA breakages, each providing support under different...

2023年7月25日 · DNA repair is crucial to correcting the mistakes our replicative machinery makes when forming new materials within our bodies. Damage to DNA molecules, if left unrepaired, can often lead to carcinogenesis, which is the development of cancer cells in the affected area that can easily spread and replicate through mitosis.
