Free‐Standing Halogen‐Bonded Nanosheets Formed by Ultrasonic Liquid Exfoliation

Advanced Science, EarlyView.
Free‐standing nanosheets held together by halogen bonding interactions (XB), formed through ultrasonic liquid exfoliation of layered molecular crystals, are reported here for the first time. The work challenges the conventional requirement for strong in‐layer interactions for the formation of stable nanosheets through liquid exfoliation and establishes

Self-assembled guanine ribbons as wide-bandgap semiconductors

, 2001
We present a first principle study about the stability and the electronic properties of a new biomolecular solid-state material, obtained by the self-assembling of guanine (G) molecules.

Sonoepigenetic Modification Mechanoprimes Early Osteogenic Commitment in Mesenchymal Stem Cells

Advanced Science, EarlyView.
Brief 10 min bursts of high frequency (10 MHz) vibrational mechanostimulation to stem cells are shown to activate their epigenetic machinery to condition their differentiation down an osteogenic lineage within just 3 days, which is much earlier than that with other forms of mechanostimuli, and without requiring any biochemical additives. Abstract Cells

Lactylation‐Driven YTHDC1 Alleviates MASLD by Suppressing PTPN22‐Mediated Dephosphorylation of NLRP3

Advanced Science, EarlyView.
In MASLD, YTHDC1 undergoes increased lactylation and ubiquitination, reducing its expression. AARS1 mediates lactylation at lysine 565, while disrupted binding to LDHA further promotes lactylation, suppressing YTHDC1. This downregulation enhances PTPN22 mRNA stability, leading to NLRP3 dephosphorylation and activation, which exacerbates inflammation ...

Uric Acid Functions as an Endogenous Modulator of Microglial Function and Amyloid Clearance in Alzheimer's Disease

Advanced Science, EarlyView.
Higher serum UA levels are associated with reduced AD risk in epidemiological studies. UA enhances microglial phagocytic capacity primarily by restoring CD36 and TREM2 receptor recycling that is impaired by Aβ exposure. Therapeutically, UA supplementation improves cognitive function and reduces neuropathology in AD mouse model by enhancing microglial ...

Intermediate filaments spatially organize intracellular nanostructures to produce the bright structural blue of ribbontail stingrays across ontogeny

Frontiers in Cell and Developmental Biology
In animals, pigments but also nanostructures determine skin coloration, and many shades are produced by combining both mechanisms. Recently, we discovered a new mechanism for blue coloration in the ribbontail stingray Taeniura lymma, a species with ...

Design and Properties of Ligand-Conjugated Guanine Oligonucleotides for Recovery of Mutated G-Quadruplexes

Molecules, 2018
The formation of a guanine quadruplex DNA structure (G4) is known to repress the expression of certain cancer-related genes. Consequently, a mutated G4 sequence can affect quadruplex formation and induce cancer progression. In this study, we developed an

Modulating a Massive Set of Biomolecular Structures by Sono‐Mechanical Force

Advanced Science, EarlyView.
Using low‐power ultrasound exposure, picoNewton forces are generated to release loaded drugs after unfolding secondary structures in DNA nanoassemblies. This opens a door to reversibly manipulate a large set of biomolecular structures both inside and outside cells without the damages incurred by high‐power sonications currently used in the field ...
