The genotoxic effects of DNA lesions induced by artificial UV-radiation and sunlight
(ELSEVIER SCIENCE SA, 2010)
Solar radiation sustains and affects all life forms on Earth. The increase in solar UV-radiation at environmental levels, due to depletion of the stratospheric ozone layer, highlights serious issues of social concern. This ...
Resistance to ultraviolet-induced apoptosis in DNA repair deficient growth arrested human fibroblasts is not related to recovery from RNA transcription blockage
(ELSEVIER SCIENCE BV, 2008)
The impact of ultraviolet (UV-C) photoproducts on apoptosis induction was investigated in growth arrested (confluent) and proliferating human primary fibroblasts. Confluent fibroblasts were more resistant to UV-C-induced ...
Freqüência da mutação 844ins68 do gene da cistationina beta-sintetase em pacientes com trombose venosa profunda
(Associação Brasileira de Hematologia e Hemoterapia e daSociedade Brasileira de Transplante de Medula Óssea, 2005-03-01)
A hiper-homocisteinemia, resultante da deficiência na conversão da homocisteína em cistationina, constitui em fator de risco isolado para doenças vasculares. A mutação 844ins68 do gene da cistationina beta-sintetase é um ...
The lncRNA RMEL3 protects immortalized cells from serum withdrawal-induced growth arrest and promotes melanoma cell proliferation and tumor growth
(2018-01-01)
RMEL3 is a recently identified lncRNA associated with BRAFV600E mutation and melanoma cell survival. Here, we demonstrate strong and moderate RMEL3 upregulation in BRAF and NRAS mutant melanoma cells, respectively, compared ...
KatG, the bifunctional catalase of xanthomonas citri subsp. Citri, responds to hydrogen peroxide and contributes to epiphytic survival on citrus leaves
(Public Library of Science, 2016-03)
Xanthomonas citri subsp. citri (Xcc) is the bacterium responsible for citrus canker. This bacterium is exposed to reactive oxygen species (ROS) at different points during its life cycle, including those normally produced ...
Genotoxicity of polar and apolar extracts obtained from Qualea multiflora and Qualea grandiflora
(Elsevier B.V., 2011-10-31)
Ethnopharmacological relevance: The species Qualea grandiflora and Qualea multiflora, which belong to the Vochysiaceae family, are common in the Brazilian savannah (Cerrado biome), and the local inhabitants use these species ...
Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) production from biodiesel by-product and propionic acid by mutant strains of Pandoraea sp.
(2017-07-01)
Pandoraea sp. MA03 wild type strain was subjected to UV mutation to obtain mutants unable to grow on propionic acid (PA) but still able to produce poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [P(3HB-co-3HV)] from glycerol ...
The effect of gene tubC on the vegetative growth of benomyl-resistant strains of Aspergillus nidulans
(1994-06-29)
Two benomyl-resistant mutants, benD3 tubC41 and benD4 tubC42, of Aspergillus nidulans were isolated after UV treatment. The tubC mutations permitted good conidiation of these strains in culture media containing benomyl and ...
