A ROS‐Responsive and Mucoadhesive Thermosensitive Hydrogel Encapsulated with Mizoribine for Synergistic Dry Eye Therapy

open access: yesAdvanced Science, EarlyView.
The ROS‐responsive in situ thermosensitive MZR@SPPP hydrogel system enables dual‐stage drug loading and sustained ocular delivery. Upon administration, it gelates at ocular surface temperature, enhancing ocular adhesion. By scavenging free radicals, restoring NRF2‐mediated antioxidant defense and mitochondrial homeostasis, and suppressing inflammatory ...

SEC Mediates m6A Deposition and Transcription Pause Release to Drive Cell Identity Transition

open access: yesAdvanced Science, EarlyView.
The SEC promotes cell identity transitions by facilitating transcription pause release at key identity‐associated genes, including Klf4 and Myc during iPSC reprogramming and Nes and Tubb3 during ESC‐to‐neuroectodermal differentiation. During early iPSC reprogramming, this function additionally involves cooperation with METTL3‐associated m6A regulation.

Semi‐Artificial Photosynthesis Enables Light‐Driven Biomanufacturing in Non‐Photosynthetic Bacteria

open access: yesAdvanced Science, EarlyView.
A non‐invasive strategy exploits endogenous H2S metabolism in B. subtilis to drive in situ CdS biomineralization, enabling tight bio‐abiotic contact without genetic modification. Light harvested by the biomineralized nanoparticles powers NADPH regeneration, elevating 2’‐fucosyllactose and surfactin titres two‐ to three‐fold.

Tubocapsenolide A Overcomes Oxaliplatin Resistance in Colorectal Cancer by Targeting PLK1 to Impair CEP55–ESCRT‐Associated Vesicular Damage Clearance

open access: yesAdvanced Science, EarlyView.
Oxaliplatin‐resistant colorectal cancer cells utilize a previously unappreciated PLK1‐CEP55‐ESCRT‐driven vesicular extrusion mechanism to clear L‐OHP‐induced cellular damage. The natural withanolide Tubocapsenolide A directly targets and inhibits PLK1 to disrupt this specific damage‐clearance machinery. This blockade induces severe nucleolar stress and

Molybdenum–Gold Nanoclusters Using 2-Mercapto-5-nitrobenzimidazole as Ligand for Sensing Guanosine and Mg Ions Through a Fluorescence Turn Off–On Mechanism

open access: yesApplied Spectroscopy Practica
In this study, a new sensor for the fluorescence detection of guanosine and Mg 2+ ions using a “turn-off–on” mechanism was successfully constructed using 2-mercapto-5-nitrobenzimidazole (MNB) modified bimetallic molybdenum–gold nanoclusters (Mo-AuNCs ...

Safety and pharmacokinetics of mosliciguat, a new, inhaled soluble guanylate cyclase activator, in healthy adult subjects

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Mosliciguat (BAY 1237592), the first soluble guanylate cyclase (sGC) activator in a dry powder inhaler (DPI), could potentially treat pulmonary hypertension with a more targeted delivery than systemic sGC stimulators. We report safety and tolerability of mosliciguat in healthy men.

RNA‐centric world of retroviruses: unravelling the molecular strategies of genomic RNA packaging

open access: yesBiological Reviews, EarlyView.
ABSTRACT Retroviruses constitute a unique group of RNA viruses that have profoundly influenced both evolutionary trajectories and biomedical research. Their ability to reverse transcribe and integrate into host genomes has shaped genomic architecture across species and contributed to our understanding of oncogenes, gene regulation, and RNA biology ...

How developmental stressors affect mitochondrial respiratory function: a systematic review and meta‐analysis

open access: yesBiological Reviews, EarlyView.
ABSTRACT The environmental conditions organisms experience during early development can have powerful and sustained effects on morphology, physiology, behaviour, and performance. Such developmental effects can influence reproductive success, survival, and life‐history strategies and can be transmitted across generations (i.e.

A Cytosine‑Bulged (3+1) Hybrid G‑Quadruplex Formed by the Chicken DNA Replication Origin

open access: yesChemistry – A European Journal, EarlyView.
The first high‐resolution structure of an OGRE‐derived G‐quadruplex from the chicken β‐globin replication origin reveals an intramolecular three‐layer (3+1) hybrid fold with a cytosine bulge and an unprecedented 5'‐outer‐quartet anti guanine, creating a distinctive surface for molecular recognition.
