Nascent Extracellular Matrix Converts Biomaterial Cues into Cell Fate Decisions

open access: yesAdvanced Science, EarlyView.
This study uncovers a tri‐directional interplay among cells, hydrogels, and their nascent extracellular matrix. Hydrogel norbornene modification alters CD44‐mediated cell–hydrogel interactions, which shape nascent matrix deposition, composition, and spatial organization.

Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism

open access: yesAdvanced Science, EarlyView.
Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.

Bioelectrochemically Powered Out‐of‐Equilibrium Hydrogels Enable Feedback‐Regulated Functions

open access: yesAdvanced Science, EarlyView.
A bioelectrochemically powered hydrogel operates far from equilibrium via an antagonistic redox cycle that regulates disulfide exchange within a polyrotaxane network. Coupling electrochemical mediator cycling with enzymatic feedback enables dynamic control of hydrogel mechanics and transport properties, driving glucose‐responsive insulin release with ...

Cysteine Thioaldehydes: Photolytic Generation, Reactivity, and Biological Implications

open access: yesAngewandte Chemie, EarlyView.
Photolysis of cysteine phenacylsulfides bearing non‐conjugating electron‐withdrawing substituents leads to high conversions into cysteine thioaldehydes through a Norrish type‐II pathway. This methodology enabled the study of the aqueous reactivity of these important biosynthetic intermediates, which, depending on peptide sequence, pH and buffer ...

Non‐Coding Transcripts From Diversified Members of IgLec Family Protect Antiviral Effectors From Viral miRNA

open access: yesAdvanced Science, EarlyView.
The IgLec gene family generates both protein‐coding antiviral effectors and non‐coding transcripts. Upon viral infection, non‐coding transcripts are preferentially targeted by viral miR‐N48, thereby buffering protein‐coding isoforms from repression. Depletion of these decoy transcripts compromises antiviral defense, revealing a non‐coding RNA‐mediated ...

Intermolecular Carbon–Carbon Naphthalene Coupling Involves a Radical Mechanism Driven by Cytochrome P450 in Alternaria alternata

open access: yesAngewandte Chemie, EarlyView.
1,8‐DHN is an important intermediate to form complex aromatic ring systems. Phenol‐coupling reactions are important for the dimerization of two molecules. Here, we show that a fungal cytochrome P450 enzyme catalyzes specific C─C bonds. ABSTRACT Dihydroxynaphthalene (DHN) derivatives are precursors of biologically important molecules, including melanin ...

Characterization of Glucose Oxidase from Penicillium notatum

open access: yesFood Technology and Biotechnology, 2009
In the present study glucose oxidase (GOD) has been isolated from a culture filtrate of Penicillium notatum. The enzyme was purified by ammonium sulphate precipitation, diethylaminoethyl (DEAE) cellulose ion-exchange chromatography and Sephadex gel ...
