UVA generates pyrimidine dimers in DNA directly. [PDF]
There is increasing evidence that UVA radiation, which makes up approximately 95% of the solar UV light reaching the Earth's surface and is also commonly used for cosmetic purposes, is genotoxic. However, in contrast to UVC and UVB, the mechanisms by which UVA produces various DNA lesions are still unclear.

Formation of Cyclobutane Pyrimidine Dimers after UVA Exposure (Dark-CPDs) Is Inhibited by an Hydrophilic Extract of Polypodium leucotomos [PDF]
Exposure to sun and especially to ultraviolet radiation (UVR) exerts well known detrimental effects on skin which are implicated in malignancy. UVR induces production of cyclobutane pyrimidine dimers (CPDs), immediately during exposure and even hours ...

The compost metagenome as a source of T4 bacteriophage pyrimidine dimer glycosylase homologues [PDF]
Compost is a promising source of thermotolerant enzymes for their application in biotechnology. Homologues of bacteriophage T4 DNA glycosylase can find their application in pharmaceuticals and perfumery.

Recombination between homologous chromosomes induced by unrepaired UV-generated DNA damage requires Mus81p and is suppressed by Mms2p. [PDF]
DNA lesions caused by UV radiation are highly recombinogenic. In wild-type cells, the recombinogenic effect of UV partially reflects the processing of UV-induced pyrimidine dimers into DNA gaps or breaks by the enzymes of the nucleotide excision repair ...

Perspectives on Cyclobutane Pyrimidine Dimers—Rise of the Dark Dimers† [PDF]
ABSTRACTSome early reports demonstrate that levels of cyclobutane pyrimidine dimers (CPD) may increase after UVR exposure had ended, although these observations were treated as artifacts. More recently, it has been shown unequivocally that CPD formation does occur post‐irradiation, with maximal levels occurring after about 2–3 h.
