Highly Potent Fluorogenic Ligands for Triplex DNA: 5‐Substituted 2‐(Naphthalen‐2‐yl)‐4H‐Chromen‐4‐Ones

open access: yesChemistry – A European Journal, EarlyView.
5‐Substituted 2‐(naphthalen‐2‐yl)‐4H‐chromen‐4‐ones are reported as a novel class of highly potent and selective triplex DNA ligands. These ligands induce triplex formation at submicromolar concentrations and inhibit enzymatic activity via ligand‐mediated triplex formation.

Dynamic Control of Nucleic Acids Self‐Assembly and Expression Using Photoswitches

open access: yesChemistry – A European Journal, EarlyView.
We review here the recent progress made in the design of molecular photoswitches, and highlight their implementation for the dynamic control over nucleic acids self‐assembly and expression. ABSTRACT Synthetic nucleic acids have become readily available and now constitute versatile building blocks in materials science—where they can be used to engineer ...

Spatiotemporal cellular dynamics of the notochord shape intervertebral disc morphogenesis in the mouse embryo through apoptosis and proliferation

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The notochord is a midline structure essential for vertebrate embryogenesis, contributing to the development of the nervous system, digestive tract, and vertebral column. In particular, notochord signaling is indispensable for proper patterning and coordinated development of alternating vertebrae and intervertebral discs (IVDs ...
