A bidirectional fluorescent two-hybrid system for monitoring protein–protein interactions
Two-hybrid systems have been the cornerstone of research into protein–protein interactions, but these systems typically rely on life/death reporters that put additional selective pressure on the host organism, and potentially lead to false positives ...

Phage inducible islands in the gram-positive cocci [PDF]
The SaPIs are a cohesive subfamily of extremely common phage-inducible chromosomal islands (PICIs) that reside quiescently at specific att sites in the staphylococcal chromosome and are induced by helper phages to excise and replicate.

The LINC01116 long noncoding RNA is induced by hypoxia and associated with poor prognosis and high recurrence rates in two cohorts of lung adenocarcinoma patients. Here, we demonstrate that besides its expression in cancer cells, LINC01116 is markedly expressed in lymphatic endothelial cells of the tumor stroma in which it participates in hypoxia ...

Plant responses to auxin require proteasome-mediated degradation of Aux/IAA transcriptional repressor proteins. Here, Yang et al. show that auxin suppresses proteasome activity in a manner dependent on the proteasome regulator PTRE1 and propose a ...

A Master equation approach to modeling an artificial protein motor
Linear bio-molecular motors move unidirectionally along a track by coordinating several different processes, such as fuel (ATP) capture, hydrolysis, conformational changes, binding and unbinding from a track, and center-of-mass diffusion.

Accurate timekeeping is controlled by a cycling activator in Arabidopsis. [PDF]
Transcriptional feedback loops are key to circadian clock function in many organisms. Current models of the Arabidopsis circadian network consist of several coupled feedback loops composed almost exclusively of transcriptional repressors.

At face value, the Sin3 histone deacetylase (HDAC) complex appears to be a prototypical co-repressor complex, that is, a multi-protein complex recruited to chromatin by DNA bound repressor proteins to facilitate local histone deacetylation and ...

ATF4‐mediated stress response as a therapeutic vulnerability in chordoma
We screened 5 chordoma cell lines against 100+ inhibitors of epigenetic and metabolic pathways and kinases and identified halofuginone, a tRNA synthetase inhibitor. Mechanistically halofuginone induces an integrated stress response, with eIF2alpha phosphorylation, activation of ATF4 and its target genes CHOP, ASNS, INHBE leading to cell death ...

Engineering novel CRISPRi repressors for highly efficient mammalian gene regulation
Background CRISPR interference (CRISPRi), the repurposing of the RNA-guided endonuclease dCas9 as a programmable transcriptional repressor, allows highly specific repression (knockdown) of gene expression.

ZEB1 turns into a transcriptional activator by interacting with YAP1 in aggressive cancer types
The transcription factors ZEB1 and YAP function in different pathways yet both activate aggressive behaviour in cancer cells. Here, the authors describe that the proteins physically interact and that this changes the transcriptional activity of ZEB1 from
