Genome-wide analysis of factors affecting transcription elongation and DNA repair: a new role for PAF and Ccr4-not in transcription-coupled repair
(Public Library of Science, 2009)
RNA polymerases frequently deal with a number of obstacles during transcription elongation that need to be removed for transcription resumption. One important type of hindrance consists of DNA lesions, which are removed ...

Molecular evidence that the eukaryotic THO/TREX complex is required for efficient transcription elongation
(American Society for Biochemistry and Molecular Biology Inc., 2003)
THO/TREX is a conserved eukaryotic complex formed by the core THO complex plus proteins involved in mRNA metabolism and export such as Sub2 and Yra1. Mutations in any of the THO/TREX structural genes cause pleiotropic ...

Conjugal transfer of the Salmonella enterica virulence plasmid in the mouse intestine
(American Society for Microbiology, 2008)
BALB/c mice were infected with two Salmonella enterica serovar Typhimurium strains, one of which lacked the virulence plasmid. Transconjugants were found at high frequencies in the mouse feces and at low frequencies in the ...

Control metabólico de la sensibilidad a TRAIL en células epiteliales de mama : papel de AMPK
(2009)
La apoptosis es el mecanismo por el cual las células son eliminadas del organismo tras una serie de procesos bioquímicos controlados, en ausencia de procesos inflamatorios que dañen a los tejidos circundantes. El ligando ...

Papel del RNA en expresión genética y recombinación en Saccharomyces cerevisiae
(2004)
La información necesaria para la supervivencia celular se encuentra codificada en el genoma. Cualquier proceso que conlleve la alteración de dicha información puede provocar la incapacidad del organismo para sobrevivir, ...

The S-phase checkpoint is required to respond to R-loops accumulated in THO mutants
(American Society for Microbiology, 2009)
Cotranscriptional R-loops are formed in yeast mutants of the THO complex, which functions at the interface between transcription and mRNA export. Despite the relevance of R-loops in transcription-associated recombination, the ...

Identification and functional characterization of Sphingomonas macrogolitabida strain TFA genes involved in the first two steps of the tetralin catabolic pathway
(American Society for Microbiology, 2003-03)
Five genes involved in the two initial steps of the tetralin biodegradation pathway of Sphingomonas macrogolitabida strain TFA have been characterized. ThnA1A2 and ThnA3A4, components of the ring-hydroxylating dioxygenase, ...
