Principal factors that determine the extension of detection range in molecular beacon aptamer/conjugated polyelectrolyte bioassays. [PDF]

, 2015
A strategy to extend the detection range of weakly-binding targets is reported that takes advantage of fluorescence resonance energy transfer (FRET)-based bioassays based on molecular beacon aptamers (MBAs) and cationic conjugated polyelectrolytes (CPEs).

A new type of Na+-driven ATP synthase membrane rotor with a two-carboxylate ion-coupling motif [PDF]

, 2013
: The anaerobic bacterium Fusobacterium nucleatum uses glutamate decarboxylation to generate a transmembrane gradient of Na+. Here, we demonstrate that this ion-motive force is directly coupled to ATP synthesis, via an F1Fo-ATP synthase with a novel Na ...

ATP Hydrolysis by α‐Synuclein Amyloids is Mediated by Enclosing β‐Strand

Advanced Science, EarlyView.
Pathological amyloids have been considered chemically inert until recently. Here it is shown that α‐synuclein amyloids catalyze the hydrolysis of the universal energy molecule, ATP. The cryo‐EM structure of the complex reveals an additional β‐strand (purple) that encloses the ATP‐binding site. Within the cavity, several lysine residues are required for

Intranasal Mitochondrial Transplantation Restores Mitochondrial Function and Modulates Glial–Neuronal Interactions in a Genetic Parkinson’s Disease Model of UQCRC1 Mutation

Cells
The intranasal delivery of exogenous mitochondria is a potential therapy for Parkinson’s disease (PD). The regulatory mechanisms and effectiveness in genetic models remains uncertain, as well as the impact of modulating the mitochondrial permeability ...

Nanoscale ATP-Responsive Zeolitic Imidazole Framework-90 as a General Platform for Cytosolic Protein Delivery and Genome Editing.

Journal of the American Chemical Society, 2019
Metal-organic frameworks (MOFs) are an emerging class of nanocarriers for drug delivery, owing to their tunable chemical functionality. Here we report ATP-responsive zeolitic imidazole framework-90 (ZIF-90) as a general platform for cytosolic protein ...

Photo‐Empowered Macrophage‐Based Drug Delivery System Overcomes Motility Suppression and Significantly Enhances Deep Tumor Drug Delivery

Advanced Science, EarlyView.
This study develops a photo‐empowered macrophage‐based (PEM) drug delivery system that provides a novel and effective solution for restoring cellular motility to enhance drug delivery and overcome hypoxia‐induced multidrug resistance. The construction of the PEM system fully exploits the unique biological properties of macrophages and the energy ...

Elleborus in Anglo-Saxon England, 900–1100: Tunsingwyrt and Wodewistle [PDF]

, 2013
This article examines the meanings of the Latin word elleborus in later Anglo-Saxon England. They prove to have varied, from Ælfric’s implicit assertion around 1000 that elleborus had no vernacular Old English counterpart, to the association by the ...

H+ Transport is an Integral Function of the Mitochondrial ADP/ATP Carrier

Nature, 2019
The mitochondrial ADP/ATP carrier (AAC) is a major transport protein of the inner mitochondrial membrane. It exchanges mitochondrial ATP for cytosolic ADP and controls cellular production of ATP.
