The Total mRNA Concentration Buffering System in Yeast is Global Rather than Gene-specific
(Cold Spring Harbor Laboratory Press, 2021)
Gene expression in eukaryotes does not follow a linear process from transcription to translation and mRNA degradation. Instead it follows a circular process in which cytoplasmic mRNA decay crosstalks with nuclear transcription. ...

Topoisomerase IIα represses transcription by enforcing promoter-proximal pausing
(Elsevier, 2021)
Accumulation of topological stress in the form of DNA supercoiling is inherent to the advance of RNA polymerase II (Pol II) and needs to be resolved by DNA topoisomerases to sustain productive transcriptional elongation. ...

Surface modulation of single-walled carbon nanotubes for selective bacterial cell agglutination
(Dove Medical Press, 2019)
Background: Bacterial resistance to antibiotics is one of the biggest challenges facing medicine today. Anti-adhesive therapy, using inhibitors of bacterial adhesion to epithelial cells, one of the first stages 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 ...

Calmodulin in Paramecium: Focus on Genomic Data
(MDPI, 2022)
Calcium (Ca2+) is a universal second messenger that plays a key role in cellular signaling. However, Ca2+ signals are transduced with the help of Ca2+-binding proteins, which serve as sensors, transducers, and elicitors. ...

Adaptation of Salmonella enterica to bile: essential role of AcrAB-mediated efflux
(Society for Applied Microbiology, 2018)
Adaptation to bile is the ability to endure the lethal effects of bile salts after growth on sublethal concentrations. Surveys of adaptation to bile in Salmonella enterica ser. Tyhimurium reveal that active efflux is ...

Proteomic insight into the effects of the Salmonella ubiquitin ligase SlrP on host cells
(Elsevier, 2016)
The virulence of the human and animal pathogen Salmonella enterica serovar Typhimurium is dependent on two type III secretion systems. These systems translocate proteins called effectors into eukaryotic host cells. SlrP ...

Fusarium photoreceptors
(MDPI, 2023-03-04)
Light is an important modulating signal in fungi. Fusarium species stand out as research models for their phytopathogenic activity and their complex secondary metabolism. This includes the synthesis of carotenoids, whose ...
