CRISPR-Cas9 based target validation revealed that the sensitivity of the p53-reactivating compound RITA is independent of functional p53 and is reliant on the regulation of the DNA damage-activated Fanconi anemia pathway.
25-Hydroxycholesterol induces miR-185 to suppress lipid and cholesterol synthesis pathways and inhibit viruses such as hepatitis C virus (HCV), that use host membranes to propagate. HCV counteracts this by suppressing miR-185 expression to drive increased cellular lipid content.
We asked a collection of chemical biologists: “What is the most exciting frontier area in chemical biology, and what key technology is needed to advance knowledge and applications at this frontier?”
Abundant frontiers at the interface of chemistry and biology promise another decade of technological innovation and scientific discovery by chemical biologists.
A new high-resolution crystal structure of the subdomain from a catalytically active group II intron reveals important conformational rearrangements necessary to achieve the fully formed catalyst. This structure provides the first atomic-resolution structure of an RNA folding intermediate.
Misregulated transcription factors play prominent roles in human disease, but their dynamic protein-protein interaction network has long made the goal of transcription-targeted therapeutics impractical. Recent advances in technologies for modulating protein interaction networks mean that the end of the quest is in sight.
X-ray crystallography, the workhorse of structural biology, has been revolutionized by the advent of serial femtosecond crystallography using X-ray free electron lasers. Here, the fast pace and history of discoveries are discussed together with current challenges and the method's great potential to make new structural discoveries, such as the ability to generate molecular movies of biomolecules at work.
Negatively charged lipids act as allosteric modulators for structural changes and activation of the GPCR β2-adrenergic receptor through direct intracellular interactions between lipid headgroups and the receptor.
Stable-isotope tracing and metabolomics analysis comparing pre-adipocytes and differentiated adipocytes revealed a shift from glucose and glutamine utilization to increased branched chain amino acid catabolic flux to generate acetyl–coenzyme A.
