Ultraviolet-B-Induced Cyclobutane-pyrimidine Dimer Formation and Repair in Arctic Marine Macrophytes(para)

ABSTRACT

The significance of ultraviolet-B radiation (UVBR: 280-315 nm)-induced DNA damage as a stress factor for Arctic marine macrophytes was examined in the Kongsfjord (Spitsbergen, 78 deg 55.5'N, 11 deg 56.0'E) in summer. UVBR penetration in the water column was monitored as accumulation of cyclobutanepyrimidine dimers (CPD) in bare DNA. This showed that UVBR transpar...

DNA Damage, a Biomarker of Carcinogenesis: Its Measurement and Modulation by Diet and Environment
Critical Reviews in Food Science and Nutrition ; Free radicals and other reactive oxygen or nitrogen species are constantly generated in vivo and can cause oxidative damage to DNA. This damage has been implicated to be important in many diseases, including cancer. The assessment of damage in various biological matrices, such as tissues, cells,
Application of the Comet Assay for Investigation of Oxidative DNA Damage in Equine Peripheral Blood Mononuclear Cells1,2
The Journal of Nutrition ; ABSTRACT Oxidative stress occurs when antioxidant defense mechanisms are overwhelmed by free radicals and may lead to DNA damage, which has been implicated in processes such as aging and diseases such as cancer. The two main techniques presently used to quantify DNA damage are measurement of
DNA damage response
The Scientist ; FOUNDATIONS "In 1986, I was trying to identify a RecA-related protein in Saccharomyces cerevisiae whose abundance increased in response to DNA damage. I expected a recombinase but when I cloned the gene, it encoded ribonucleotide reductase, which cross-reacted with the antibody I used. I was

Ccr4-Not Complex mRNA Deadenylase Activity Contributes to DNA Damage Responses in Saccharomyces cerevisiae
Genetics ; ABSTRACT DNA damage checkpoints regulate gene expression at the transcriptional and post-transcriptional level. Some components of the yeast Ccr4-Not complex, which regulates transcription as well as transcript turnover, have previously been linked to DNA damage responses, but it is unclear if this

Compared to the control group of dogs (n =
Genetic Analysis of Saccharomyces cerevisiae H2A Serine 129 Mutant Suggests a Functional Relationship Between H2A and the Sister-Chromatid Cohesion Partners Csm3-Tof1 for the Repair of Topoisomerase I-Induced DNA Damage
Genetics ; ABSTRACT Collision between a topoisomerase I-DNA intermediate and an advancing replication fork represents a unique form of replicative damage. We have shown previously that yeast H2A serine 129 is involved in the recovery from this type of damage. We now report that efficient repair also requires
Photosensitized DNA Damage and its Protection via a Novel Mechanism[dagger]
Photochemistry and Photobiology ; ABSTRACT UVA, which accounts for approximately 95% of solar UV radiation, can cause mutations and skin cancer.
