Data‐Independent Acquisition Mass Spectrometry in Tumor Classification and Cancer Biomarker Research

Mass Spectrometry Reviews, EarlyView.
Abstract Cancer treatment is far from optimal also because current classification systems do not reflect the complex molecular status of the tumor and its phenotype in sufficient detail. To construct molecular tumor classifiers, omics tools provide complex molecular data reflecting many aspects from genotype to phenotype.

A membrane-inserted structural model of the yeast mitofusin Fzo1 [PDF]

, 2017
Mitofusins are large transmembrane GTPases of the dynamin-related protein family, and are required for the tethering and fusion of mitochondrial outer membranes.

Microglial Activation Under Hypoxic Conditions in Early Alzheimer's Disease: Can Natural SIRT1 Activators Be Therapeutic Allies in the Inflammation–Energy Axis?

Phytotherapy Research, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a progressive neurodegenerative condition characterized by a preclinical stage that typically lasts for decades. Early on during this time, microglia react to pathological changes and become protective and even transiently delay neurodegeneration.

Heme Oxygenase Induction Suppresses Hepatic Hepcidin and Rescues Ferroportin and Ferritin Expression in Obese Mice [PDF]

, 2017
Hepcidin, a phase II reactant secreted by hepatocytes, regulates cellular iron levels by increasing internalization of ferroportin-a transmembrane protein facilitating egress of cellular iron.

Mitofusins Mfn1 and Mfn2 Are Required to Preserve Glucose- but Not Incretin-Stimulated β-Cell Connectivity and Insulin Secretion

bioRxiv, 2020
Aims/hypothesis Mitochondrial glucose metabolism is essential for stimulated insulin release from pancreatic beta cells. Whether mitochondrial networks may be important for glucose or incretin sensing has yet to be determined.

Harnessing energy metabolism for enhanced bone defect repair: Mechanisms and therapeutic strategies

VIEW, EarlyView.
This review addresses the critical challenge of bone defect repair by focusing on the underexplored role of cellular energy metabolism. It synthesizes regulatory mechanisms in bone‐forming cells and sums up innovative strategies—leveraging cell derivatives, active factors, and biomimetic scaffolds—to modulate metabolism for enhanced regeneration.

Mitochondrial Quality Control in Age-Related Pulmonary Fibrosis. [PDF]

, 2020
Idiopathic pulmonary fibrosis (IPF) is age-related interstitial lung disease of unknown etiology. About 100,000 people in the U.S have IPF, with a 3-year median life expectancy post-diagnosis.

Ageing‐Dependent Thyroid Hormone Receptor α Reduction Activates IP3R1‐Meditated Ca2+ Transfer in MAM and Exacerbates Skeletal Muscle Atrophy in Mice

Cell Proliferation, EarlyView.
During skeletal muscle ageing, down‐regulation of TRα expression activates IP3R1 transcriptional expression, promotes MAM calcium transport, triggers mitochondrial calcium overload and apoptosis, leading to skeletal muscle atrophy. Restoring TRα expression can improve IP3R1‐mediated mitochondrial calcium overload and apoptosis in ageing skeletal muscle

Cyclin B1/Cdk1 phosphorylation of mitochondrial p53 induces anti-apoptotic response. [PDF]

, 2010
The pro-apoptotic function of p53 has been well defined in preventing genomic instability and cell transformation. However, the intriguing fact that p53 contributes to a pro-survival advantage of tumor cells under DNA damage conditions raises a critical ...
