Solar uv radiation-induced dna bipyrimidine photoproducts: Formation and mechanistic insights
(Springer Verlag, 2015)
Excited States of Proton-Bound DNA/RNA Base Homodimers: Pyrimidines
(American Chemical Society, 2014-07)
We are presenting the electronic photofragment spectra of the protonated pyrimidine DNA base homodimers. Only the thymine dimer exhibits a well structured vibrational progression, while the protonated monomer shows broad ...
Major roles of for pyrimidine dimers, nucleotide excision repair and ATR in the alternative splicing response to UV irradiation
(Elsevier B.V., 2017-03-21)
We have previously found that UV irradiation promotes RNA polymerase II (RNAPII) hyperphosphorylation and subsequent changes in alternative splicing (AS). We show now that UV-induced DNA damage is not only necessary but ...
Quantification of Cyclobutane Pyrimidine Dimers Induced by UVB Radiation in Conidia of the Fungi Aspergillus fumigatus, Aspergillus nidulans, Metarhizium acridum and Metarhizium robertsii
(WILEY-BLACKWELL, 2010)
Conidia are responsible for reproduction, dispersal, environmental persistence and host infection of many fungal species. One of the main environmental factors that can kill and/or damage conidia is solar UV radiation. ...
Functional acclimation to solar UV-B radiation in Gunnera magellanica, a native plant species of southernmost Patagonia
(Wiley Blackwell Publishing, Inc, 2003-12)
The ecosystems of Tierra del Fuego (in southern Patagonia, Argentina) are seasonally exposed to elevated levels of ultraviolet-B radiation (UV-B: 280-315 nm), due to the passage of the 'ozone hole' over this region. In the ...
p53 Mutant Human Glioma Cells Are Sensitive to UV-C-Induced Apoptosis Due to Impaired Cyclobutane Pyrimidine Dimer Removal
(AMER ASSOC CANCER RESEARCH, 2009)
The p53 protein is a key regulator of cell responses to DNA damage, and it has been shown that It sensitizes glioma cells to the alkylating agent temozolomide by up-regulating the extrinsic apoptotic pathway, whereas it ...
The electrochemical reduction of the purines guanine and adenine at platinum electrodes in several room temperature ionic liquids
(2010-02-05)
The reduction of guanine was studied by microelectrode voltammetry in the room temperature ionic liquids (RTILs) N-hexyltriethylammonium bis (trifluoromethanesulfonyl) imide [N6,2,2,2][N(Tf)2], 1-butyl-3-methylimidazolium ...

Biflavonoids from Araucaria angustifolia protect against DNA UV-Induced damage
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Ultraviolet radiation is one of the most deleterious forms of radiation to terrestrial organisms and is involved in formation of mutagenic pyrimidine dimers and oxidized nucleotides. The biflavonoid fraction (BFF), extracted ...
