Electron Transport Chain Protocol v1

This protocol describes the procedure for analyzing Electron Transport Chain activity of Complexes 1, 2, and 4 in mitochondria isolated from fibroblasts used by the Seifert Lab. It follows the "Electron Transport Chain Protocol" (ETCP) described in: Vekaria, H.J., Kalimon, O.J., Prajapati, P., Velmurugan, G.V., Sullivan, P.G., 2024.

Electron transport in xanthine oxidase. A model for other biological electron transport chains

Biophysical Journal, 1976
Part of the catalytic function of xanthine oxidase (XO) involves the transfer of two electrons from a substrate to a molybdenum ion on the enzyme followed by equilibration of these electrons among other electron resting sites on the enzyme. The electrons are removed from the enzyme at a flavin by oxygen to form hydrogen peroxide.

Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

Advanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Mandibular-Derived Monocytes from 1-Year-Old Mice Have Enhanced Osteoclast Differentiation and Differentially Regulated Gene Expression Compared to Femur-Derived Monocytes

Biology
It is well established that both men and women lose bone as they age. While recent studies suggest unique molecular signatures of mineral-resorbing cells at different anatomical locations, most studies focus on long bones, and little is known about ...

Synergistic Osteogenesis After Co‐Administration of cmRNAs Encoding BMP‐2 and BMP‐7 Utilizing a Transcript‐Activated Matrix

Advanced Functional Materials, EarlyView.
This study demonstrates that the dual delivery of BMP‐2/‐7 coding cmRNAs for bone healing is demonstrated as feasible, safe, and highly osteogenic. Compared to single BMP‐2 or BMP‐7 cmRNAs, the combination enhances the production of both mineral and organic components of the extracellular matrix when delivered using a collagen‐HA scaffold, supporting ...

The association of mitochondrial morphology and supercomplex redistribution with skeletal muscle oxidative capacity in older adults

Physiological Reports
Skeletal muscle maximal oxidative capacity (ATPmax) is a key component of age‐related sarcopenia and muscle health. The contribution of mitochondrial morphology and electron transport chain supercomplex (SC) assemblies to ATPmax has yet to be determined ...

Mechanically Tunable Bone Scaffolds: In Vivo Hardening of 3D‐Printed Calcium Phosphate/Polycaprolactone Inks

Advanced Functional Materials, EarlyView.
A 3D bone scaffold with osteogenic properties and capable of hardening in vivo is developed. The scaffold is implanted in a ductile state, and a phase transformation of the ceramic induces the stiffening and strengthening of the scaffold in vivo. Abstract Calcium phosphate 3D printing has revolutionized customized bone grafting.

DENTA: A Dual Enzymatic Nanoagent for Self‐Activating Tooth Whitening and Biofilm Disruption

Advanced Functional Materials, EarlyView.
The nanoapatite with dual enzymes (DENTA) accumulates in dentinal tubules, reducing hypersensitivity caused by dental nerve exposure and facilitating continuous ROS generation through salivary glucose for effective, long‐term whitening. The dentin structures remain non‐destructive due to the low concentration of ROS, demonstrating excellent cell ...
