Mathematical and computational modelling of post-transcriptional gene relation by micro-RNA [PDF]

open access: yes, 2009
Mathematical models and computational simulations have proved valuable in many areas of cell biology, including gene regulatory networks. When properly calibrated against experimental data, kinetic models can be used to describe how the concentrations of

Staphylococcus aureus Small Colony Variants (SCVs): A Road Map for the Metabolic Pathways Involved in Persistent Infections

open access: yesFrontiers in Cellular and Infection Microbiology, 2014
Persistent and relapsing infections, despite apparently adequate antibiotic therapy, occur frequently with many pathogens, but it is an especially prominent problem with Staphylococcus aureus infections. For the purposes of this review, persistence will

Structural insights into the dynamics and function of the C-terminus of the E. coli RNA chaperone Hfq [PDF]

open access: yes, 2011
The hexameric Escherichia coli RNA chaperone Hfq (Hfq(Ec)) is involved in riboregulation of target mRNAs by small trans-encoded RNAs. Hfq proteins of different bacteria comprise an evolutionarily conserved core, whereas the C-terminus is variable in ...

RBPs in Hematopoietic Stem Cell Maintenance and Leukemia Initiation: Critical Gaps

open access: yesArchives of Advances in Biosciences
Context RNA-binding proteins (RBPs) are key regulators of post-transcriptional gene expression and play essential roles in hematopoietic stem cell (HSC) function.

Mechanisms and therapeutic opportunities of the ribotoxic stress response in cancer

open access: yesMolecular Oncology, EarlyView.
Cancer cells' high translational demand creates opportunities to therapeutically target ribosome function. Ribosome stalling and collisions activate ZAKα and the ribotoxic stress response (RSR), which can trigger rapid, p53‐independent apoptosis in cancer.

Regulation of the lncRNA NEAT1 by p53‐ΔNp63 crosstalk modulates the DNA damage response and therapeutic efficacy in HNSCC

open access: yesMolecular Oncology, EarlyView.
In head and neck squamous cell carcinoma (HNSCC) p53 and p63 exert opposite roles on the transcription regulation of the lncRNA NEAT1. Under basal conditions, p53 levels are low and p63 represses NEAT1 expression. Upon genotoxic stress, p53 is rapidly induced, displacing p63 from the NEAT1 promoter leading to NEAT1 transcriptional activation and ...

p190A/ARHGAP35 and p190B/ARHGAP5 proteins in endometrial cancer: a novel cancer‐relevant paralog interplay

open access: yesMolecular Oncology, EarlyView.
This study identifies ARHGAP5, in addition to the frequently mutated ARHGAP35, as significantly mutated in endometrial cancer. Mutations in both genes co‐occur and are associated with their correlated downregulation. Functional CRISPR studies show that both paralogs regulate similar pathways, including actin cytoskeleton organization.

Processing and turn-over of small non-coding RNA OxyS in E. coli & post-transcriptional regulation of RpoS levels by small non-coding RNAs OxyS and DsrA and the Hfq protein in E. coli

open access: yes, 2010
RpoS ist ein bedeutender Sigmafaktor der stationären Wachstumsphase in E. coli. Die rpoSmRNA ist eine der ersten RNAs für die unter verschiedenen Stressbedingungen eineRegulation durch mindestens drei small non-coding RNAs gezeigt wurde. Zwei dieser dreisRNAs sind an der Aktivierung der rpoS mRNA Translation beteiligt.

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

open access: yesFEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

open access: yesFEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.
