AtCAF-1 mutants show different DNA damage responses after ultraviolet-B than those activated by other genotoxic agents in leaves
(Wiley Blackwell Publishing, Inc, 2019-06)
Chromatin assembly factor-1 (CAF-1) is a histone H3/H4 chaperone that participates in DNA and chromatin interaction processes. In this manuscript, we show that organs from CAF-1 deficient plants respond differently to ...
Estudo do gene da fotoliase de tripanossomatídeos: expressão heteróloga do gene de Trypanosoma brucei EM Trypanosoma cruzi
(Universidade Federal de Minas GeraisUFMG, 2014-03-31)
The Trypanosoma cruzi and Trypanosoma brucei are the protozoa parasites that cause African and American trypanosomiasis. Both are characterized by the presence of a single flagellum, a kinetoplast, which is elongated and ...
Micronucleated erythrocytes in newborns rats exposed to three different types of ultraviolet-A (UVA) lamps from commonly uses devices
(Elsevier, 2016-12)
Exposure to ultraviolet-A (UVA) light can accidentally cause adverse effects in the skin and eyes. UVA induces DNA damage directly by creating pyrimidine dimers or by the formation of reactive oxygen species that can ...
Ultraviolet-A Light Induces Micronucleated Erythrocytes in Newborn Rats
(SciTechnol, 2016-04-08)
Background: Ultraviolet-A (UV-A) light induce DNA damage by
creating pyrimidine dimers, or indirectly affects DNA by the formation
of reactive oxygen species. The objective was to determine DNA
damage by micronucleus ...
Ensayo de clonación de la proteína dihidropirimidina deshidrogenasa (DHPD) de papa en el vector pGBKT7
(Universidad de los AndesMicrobiologíaFacultad de CienciasDepartamento de Ciencias Biológicas, 2022-07-25)
La proteína dihidropirimidina deshidrogenasa (DHPD) es la primera enzima involucrada en la ruta del catabolismo de pirimidinas. Se ha observado que la DHPD se sobreexpresa en plantas de Oryza sativa (arroz) sometidas a ...
The interplay of UV and cutaneous papillomavirus infection in skin cancer development
(Public Library Of Science, 2017-11)
Cutaneous human papillomaviruses (HPVs) are considered as cofactors for non-melanoma skin cancer (NMSC) development, especially in association with UVB. Extensively studied transgenic mouse models failed to mimic all aspects ...
Solar UV radiation modulates daily production and DNA damage of marine bacterioplankton from a productive upwelling zone (36°S), Chile
(Elsevier Science, 2007-04)
In upwelling ecosystems, such as the Humboldt Current system (HCS) off Concepción, the effects of solar radiation on bacterioplankton incorporation rates have been related to previous light acclimation and responses to ...
Extensive loss of cell-cycle and DNA repair genes in an ancient lineage of bipolar budding yeasts
(Public Library of Science, 2019-05)
Cell-cycle checkpoints and DNA repair processes protect organisms from potentially lethal mutational damage. Compared to other budding yeasts in the subphylum Saccharomycotina, we noticed that a lineage in the genus ...
