Complex transcriptional and post‐transcriptional regulation of an enzyme for lipopolysaccharide modification [PDF]
Molecular Microbiology, 2013 SummaryThe PhoQ/PhoP two‐component system activates many genes for lipopolysaccharide (LPS) modification when cells are grown at low Mg2+ concentrations. An additional target of PhoQ and PhoP is MgrR, an Hfq‐dependent small RNA that negatively regulates expression of eptB, also encoding a protein that carries out LPS modification.

Multi-faceted regulation of CREB family transcription factors
Frontiers in Molecular NeurosciencecAMP response element-binding protein (CREB) is a ubiquitously expressed nuclear transcription factor, which can be constitutively activated regardless of external stimuli or be inducibly activated by external factors such as stressors, hormones ...

Transcriptional control: repression by local chromatin modification
, 2008 It is becoming increasingly clear that chromatin modification plays a fundamental part in transcriptional control. Recent studies provide new insights into how transcriptional repressors, in addition to blocking activators, may recruit repression ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Hyperlipidemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD). Although statins are the cornerstone of lipid‐lowering therapy, their use may be limited in some patients by adverse effects. This study evaluated the possible impact of non‐drug treatment using double‐filtration plasmapheresis (DFPP) on CD14+

The essential role of YAP O-GlcNAcylation in high-glucose-stimulated liver tumorigenesis
Nature Communications, 2017 Yap is a transcriptional factor involved in tumorigenesis. Here the authors show that a previously unknown post-translational modification of Yap, O-GlcNAcylation, increases its transcriptional activity and is required for high glucose-induced liver ...
