FOXQ1 Regulates Brain Endothelial Mitochondrial Function by Orchestrating Calcium Signaling and Cristae Morphology

open access: yesAdvanced Science, EarlyView.
FOXQ1 emerges as a master transcriptional regulator of brain endothelial metabolism, orchestrating mitochondrial function through dual control of calcium signaling and cristae organization. This study reveals that brain endothelial cells rely on oxidative phosphorylation rather than glycolysis alone, challenging the current metabolic paradigm and ...

Method of detecting and counting bacteria [PDF]

open access: yes, 1976
An improved method is provided for determining bacterial levels, especially in samples of aqueous physiological fluids. The method depends on the quantitative determination of bacterial adenosine triphosphate (ATP) in the presence of nonbacterial ATP ...

SENP6 Maintains Mitochondrial Homeostasis by Regulating Mitochondrial Protein Import Through deSUMOylation of TOM40

open access: yesAdvanced Science, EarlyView.
SUMOylation regulates mitochondrial processes, but its impact on protein import remains unclear. TOM40 is identified, a mitochondrial outer membrane channel protein, as a substrate of deSUMOylase SENP6. TOM40 SUMOylation disrupts outer membrane complex assembly, inhibits protein import, and compromises mitochondrial homeostasis.

Rapid, quantitative determination of bacteria in water [PDF]

open access: yes, 1978
A bioluminescent assay for ATP in water borne bacteria is made by adding nitric acid to a water sample with concentrated bacteria to rupture the bacterial cells.

Hepatic ENTPD5 Is Critical for Maintaining Metabolic Homeostasis and Promoting Brown Adipose Tissue Thermogenesis

open access: yesAdvanced Science, EarlyView.
ENTPD5‐mediated conversion of extracellular adenosine triphosphate to ADP of hepatocytes is critical for maintaining hepatic glucose/lipid metabolism and promoting brown adipose tissue thermogenesis via the inhibition of adrenomedullin expression and secretion.

Increased NTPDase Activity in Lymphocytes during Experimental Sepsis

open access: yesThe Scientific World Journal, 2012
We investigated in rats induced to sepsis the activity of ectonucleoside triphosphate diphosphohydrolase (NTPDase; CD39; E.C. 3.6.1.5), an enzyme involved in the modulation of immune responses.

Microwave‐Activated Bacterial Biorobot for Multimodal Cancer Therapy

open access: yesAdvanced Science, EarlyView.
An Escherichia coli bacterial biorobot is engineered for localized microwave activation in cancer therapy. Upon activation at tumor sites, the biorobot releases glucose oxidase, inducing tumor cell death via glucose depletion and H2O2 generation catalyzed by Cu2O.

Draper‐ATG3 Interaction Positively Regulates Autophagy to Mediate Silk Gland Degradation in Bombyx mori

open access: yesAdvanced Science, EarlyView.
Draper is evolutionarily conserved across most insect species. Loss of Draper inhibits autophagy activation, delaying middle silk gland degradation in the silkworm during metamorphosis. Draper interacts with autophagy ‐ related protein 3 (ATG3) to orchestrate autophagosome formation—a process essential for silk gland degradation during the larval‐pupal
