ALDOA‐Mediated Metabolic Reprogramming is a Targetable Vulnerability for Ferroptosis Sensitization in Cancer

Advanced Science, EarlyView.
ALDOA‐depletion‐mediated glycolytic reprogramming promotes autophagy‐mediated degradation of MBOAT2, increasing the ratio of phospholipids containing pro‐ferroptotic polyunsaturated fatty acids over anti‐ferroptotic monounsaturated fatty acids, and thus sensitizing cancer cells to ferroptosis.

Single muscle fiber proteomics reveals unexpected mitochondrial specialization [PDF]

, 2015
Mammalian skeletal muscles are composed of multinucleated cells termed slow or fast fibers according to their contractile and metabolic properties. Here, we developed a high-sensitivity workflow to characterize the proteome of single fibers.

FSTL1 Orchestrates Metabolic‐Epigenetic Crosstalk: Glycolysis‐Dependent H3K18 Lactylation Drives Cartilage Fibrosis in Osteoarthritis

Advanced Science, EarlyView.
FSTL1 promotes glycolysis during chondrocyte fibrosis by triggering the HIF‐1 signaling pathway, which causes lactate to accumulate. The buildup of lactate leads to changes in histone lysine lactylation, which in turn enhances the expression of genes associated with fibrosis.

Differential Effects of Buffer pH On Ca\u3csup\u3e2+\u3c/sup\u3e-Induced ROS Emission with Inhibited Mitochondrial Complexes I and III [PDF]

, 2015
Excessive mitochondrial reactive oxygen species (ROS) emission is a critical component in the etiology of ischemic injury. Complex I and complex III of the electron transport chain are considered the primary sources of ROS emission during cardiac ...

Cardiosphere-derived cells demonstrate metabolic flexibility that Is influenced by adhesion status [PDF]

, 2017
Adult stem cells demonstrate metabolic flexibility that is regulated by cell adhesion status. The authors demonstrate that adherent cells primarily utilize glycolysis, whereas suspended cells rely on oxidative phosphorylation for their ATP needs.

The Mitochondrial Guardian α‐Amyrin Mitigates Alzheimer's Disease Pathology via Modulation of the DLK‐SARM1‐ULK1 Axis

Advanced Science, EarlyView.
Dietary habits play a key role in chronic diseases, and higher annual consumption of fruit and vegetable may lower risk of dementia. Artificial intelligence predicts the lipid‐like compound α‐Amyrin (αA) from plants with edible peels as a drug candidate against Alzheimer's disease.

Unraveling the Morphological and Functional Maturation Mechanisms Underlying Human Neural Development Using iPSCs‐Derived Neuronal Model

Advanced Science, EarlyView.
Using human induced pluripotent stem cells (hiPSCs)‐derived neuronal model, Tian and colleagues reveal that voltage‐gated calcium channels Cav1.2 and Cav1.3, and their mediated calcium ion influx, are essential for early morphogenesis of human neuronal development, while ECEL1 underlies human neuronal functional developmental maturation through CALM3 ...

Covalently bound substrate at the regulatory site triggers allosteric enzyme activation [PDF]

, 2008
The mechanism by which the enzyme pyruvate decarboxylase from yeast is activated allosterically has been elucidated. A total of seven three-dimensional structures of the enzyme, of enzyme variants or of enzyme complexes form two yeast species (three of ...

Coupling Nitrogenous Organic Wastewater Treatment and Biorefinery via N‐Cycling Bacterium

Advanced Science, EarlyView.
The vast reservoir of nitrogenous organic pollutants in industrial wastewaters can serve as untapped carbon‐nitrogen resources. This study employs the newly discovered Paracoccus sp. ZQW‐1 as a versatile chassis to simultaneously achieve N‐methylpyrrolidone (NMP) wastewater depuration and polyhydroxybutyrate (PHB) synthesis.
