The BER pathway is widely used to repair DNA damage in cells, but it can also introduce unwanted mutations and is sometimes hijacked by other pathways.
Once production of your article has started, you can track the status of your article via Track Your Accepted Article. Help expand a public dataset of research that support the SDGs. The journal publishes original observations on genetic, cellular, biochemical, structural and molecular aspects of DNA repair, mutagenesis, cell cycle regulation, apoptosis and other biological The journal publishes original observations on genetic, cellular, biochemical, structural and molecular aspects of DNA repair, mutagenesis, cell cycle regulation, apoptosis and other biological responses in cells exposed to genomic insult, as well as their relationship to human disease. DNA Repair publishes full-length research articles, brief reports on research, and reviews. The journal welcomes articles describing databases, methods and new technologies supporting research on DNA repair and responses to DNA damage.
The conference discusses through plenary sessions the overall standpoint of DNA repair. The papers presented and other important documents, such as short summaries by the workshop session conveners, comprise this book. The compilation describes the opposing views, those that agree and dispute about certain topic areas. This book, divided into 15 parts, is arranged according to the proceedings in the conference. The plenary sessions are grouped with the related workshop and poster manuscripts.
DNA damage and repair in plants – from models to crops
DNA repair diseases: what do they tell us about cancer and aging? Send correspondence to. The discovery of DNA repair defects in human syndromes, initially in xeroderma pigmentosum XP but later in many others, led to striking observations on the association of molecular defects and patients' clinical phenotypes. For example, patients with syndromes resulting from defective nucleotide excision repair NER or translesion synthesis TLS present high levels of skin cancer in areas exposed to sunlight. However, some defects in NER also lead to more severe symptoms, such as developmental and neurological impairment and signs of premature aging.
The consequences of DNA damage have been the subject of numerous studies in the last few decades. Replication of damaged DNA may result in an increased rate of mutations in the progeny, which may impart deleterious consequence on the organism. Various types of cancers have been linked to DNA damages and it is believed that the initiation of carcinogenesis may result from misreplication of the damaged DNA. DNA repair systems maintain the integrity of the genome by removing the damaged base, sugar, or phosphate from the DNA. In humans, specific DNA repair deficiencies have been associated with elevated risks of diseases, notably cancer, which underscores the importance of DNA repair. DNA damage is also known to induce lesion bypass polymerases which are error-prone on undamaged DNA and may bypass lesions in error-free or error-prone manners.

Competing interests: The author has declared that no competing interests exist. All species require DNA repair pathways to maintain the integrity of their genomes. Bacterial damage repair mechanisms have broader roles encompassing responses to stress, long-term colonization, as well as virulence. This article highlights the bacterial SOS response and its significance in bacterial adaptation and pathogenesis, as well as DNA damage responses provoked by bacterial pathogens in the mammalian host.
DNA Damage, Mutagenesis, and DNA Repair
Metrics details. DNA is subject to constant chemical modification and damage, which eventually results in variable mutation rates throughout the genome. Although detailed molecular mechanisms of DNA damage and repair are well understood, damage impact and execution of repair across a genome remain poorly defined.
It seems that you're in Germany. We have a dedicated site for Germany. Not many years ago most discussion of mutation induction by physical and chemical agents concentrated on the initial lesions induced in the DNA with the implicit assumption that once the lesions were made they were converted almost automatically to mutations by relatively simple processes associated with DNA replication.
