A Sacrificial 3D Printed Vessel‐on‐Chip Demonstrates a Versatile Approach to Model Granulation Tissue

Advanced Healthcare Materials, EarlyView.
A novel method that combines 3D printing and organ‐on‐chip technology enables the creation of hollow channels lined with endothelial cells through a fibroblast‐populated connective tissue matrix. The model supports stable metabolic culture conditions, angiogenic sprouting, and immune cell migration, thereby demonstrating an easy and versatile method to

Monitoring phosphorylation of the pyruvate dehydrogenase complex [PDF]

Analytical Biochemistry, 2009
The pyruvate dehydrogenase multienzyme complex (PDC) is a key regulatory point in cellular metabolism linking glycolysis to the citric acid cycle and lipogenesis. Reversible phosphorylation of the pyruvate dehydrogenase enzyme is a critical regulatory mechanism and an important point for monitoring metabolic activity.

Annexin A13 Protects Against Acute Kidney Injury by Inactivating TGF‐β/Smad3 Signaling

Advanced Science, EarlyView.
ANXA13 is negatively regulated by Smad3 and exerts its protective role in AKI by inactivating TGF‐β/Smad3 signaling and Smad3‐p21 cell cycle arrest pathway through binding to TβRI, inhibiting the interaction between TβRI and TβRII, thereby suppressing TβRI phosporylation.

Icaritin Ameliorates Cisplatin‐Induced Mitochondrial Metabolic Dysfunction‐Associated Nephrotoxicity and Synergistically Potentiates Its Antitumor Efficacy

Advanced Science, EarlyView.
In this study, scRNA‐seq and chemoproteomics are integrated to characterize CDDP‐bound proteins at single‐cell resolution in tumor‐bearing mice. Additionally, the research demonstrates that ICA alleviates CDDP‐induced nephrotoxicity while enhancing its chemotherapeutic efficacy.

Intracellular acetyl phosphate modulates Escherichia coli pyruvate metabolism

Acta Biochimica et Biophysica Sinica
Lysine acetylation has been shown to be an abundant and vital post-translational modification (PTM) that utilizes acetyl phosphate (AcP) as one of the acetyl group donors in bacteria. The pyruvate dehydrogenase (PDH) complex catalyzes the conversion from

Cryo-EM snapshots of a native lysate provide structural insights into a metabolon-embedded transacetylase reaction

Nature Communications, 2021
How is acetyl-CoA produced in the context of the endogenous, eukaryotic pyruvate dehydrogenase complex metabolon? Here the authors dissect the embedded transacetylase reaction through biochemical, cryo-EM, HADDOCKing and molecular dynamics methods.

Alterations of the mitochondrial proteome caused by the absence of mitochondrial DNA: A proteomic view [PDF]

, 2006
The proper functioning of mitochondria requires that both the mitochondrial and the nuclear genome are functional. To investigate the importance of the mitochondrial genome, which encodes only 13 subunits of the respiratory complexes, the mitochondrial ...

Perfluorooctanoic Acid Exposure Causes Macrophage Ammonia Retention and Induces Spontaneous Miscarriages

Advanced Science, EarlyView.
PFOA exposure induces pregnancy loss by promoting glutaminolysis, which further causes ammonia accumulation in macrophages. Cellular ammonia retention results in damage to mitochondria and lysosomes, which leads to cell death eventually. Impaired lysosomes also decrease the secretion of the Cathepsin B (CTSB), and attenuate macrophage infiltration and ...
