Global impact of Salmonella type III secretion effector SteA on host cells
(Elsevier, 2014-07-11)
Salmonella enterica is a Gram-negative bacterium that causes gastroenteritis, bacteremia and typhoid fever in several animal species including humans. Its virulence is greatly dependent on two type III secretion systems, ...

Nitric oxide synthesis by nitrate reductase is regulated during development in Aspergillus
(Wiley-Blackwell, 2016)
Nitric oxide (NO) is a signalling molecule involved in many biological processes in bacteria, plants and mammals. However, little is known about the role and biosynthesis of NO in fungi. Here we show that NO production is ...

Selection of small-colony variants of salmonella enterica serovar typhimurium in nonphagocytic eucaryotic cells
(American Society for Microbiology, 2003-07)
Salmonella enterica strains are enteropathogenic bacteria that survive and proliferate within vacuolar compartments of epithelial and phagocytic cells. Recently, it has been reported that fibroblast cells are capable of ...

One step back before moving forward: regulation of transcription elongation by arrest and backtracking
(Wiley-Blackwell, 2012)
RNA polymerase II backtracking is a well-known phenomenon, but its involvement in gene regulation is yet to be addressed. Structural studies into the backtracked complex, new reactivation mechanisms and genome-wide approaches ...

Descripción y caracterización de la interacción física entre los complejos MCM y RNR en respuesta a daños en el ADN
(2022-05-24)
El complejo MCM junto con el factor Cdc45 y el complejo GINS forman la helicasa replicativa en eucariotas, cuya actividad es esencial para la viabilidad de la célula y una diana clave en la regulación de la replicación. ...

The essential WD-repeat protein Rsa4p is required for rRNA processing and intra-nuclear transport of 60S ribosomal subunits
(Oxford University Press, 2005)
We report the characterization of a novel factor, Rsa4p (Ycr072cp), which is essential for the synthesis of 60S ribosomal subunits. Rsa4p is a conserved WD-repeat protein that seems to localize in the nucleolus.In ...

Influence of chromatin factors and DNA-RNA hybrids in the repair of replication-born DSBs
(2021-06-02)
La información genética debe estar almacenada de manera segura en la molécula de ADN. Sin embargo, el ADN está continuamente expuesto a daños que alteran su estructura y secuencia dando lugar al proceso conocido cómo ...
