Mitigating disuse‐induced skeletal muscle atrophy in ageing: Resistance exercise as a critical countermeasure

open access: yesExperimental Physiology
The gradual deterioration of physiological systems with ageing makes it difficult to maintain skeletal muscle mass (sarcopenia), at least partly due to the presence of ‘anabolic resistance’, resulting in muscle loss.

HPD is an m6A Methyltransferase that Protects Colorectal Cancer Cells from Ferroptotic Cell Death by m6A Methylating SLC7A11/GPX4

open access: yesAdvanced Science, EarlyView.
This study reveals that the tyrosine metabolic enzyme HPD functions as a previously uncharacterized, METTL3‐independent m6A methyltransferase. It promotes colorectal tumor progression by coordinately regulating the SLC7A11/GPX4 axis to suppress ferroptosis.

A GLUTAMATE CYSTEINE LIGASE Gene StGSH1 Regulated by StERF10 Enhanced Glutathione Accumulation and Adaptation to Low Phosphorus Stress in Potato

open access: yesAdvanced Science, EarlyView.
The StERF10‐StGSH1 module coordinates glutathione (GSH) biosynthesis under low‐phosphorus stress. The low‐phosphate‐induced AP2/ERF transcription factor StERF10 directly activates the transcription of StGSH1 and enhances GSH accumulation. Consequently, GSH scavenges reactive oxygen species and provides sulfur for sulfolipid synthesis, facilitating the ...

IL-1ß and BMPs - Interactive players of cartilage matrix degradation and regeneration [PDF]

open access: yesEuropean Cells & Materials, 2006
Intact human adult articular cartilage is central for the functioning of the articulating joints. This largely depends on the integrity of its extracellular matrix, given the high loading forces during movements in particular in the weight-bearing joints.

NAD⁺ Reduction in Glutamatergic Neurons Induces Lipid Catabolism and Neuroinflammation in the Brain via SARM1

open access: yesAdvanced Science, EarlyView.
NAD⁺ homeostasis maintains neuronal integrity through opposing actions of NMNAT2 and SARM1. Loss of NMNAT2 in glutamatergic neurons reprograms cortical metabolism from glucose to lipid catabolism, depletes lipid stores, and triggers inflammation and neurodegeneration.

Skeletal Muscle HSF1 Alleviates Age‐Associated Sarcopenia and Mitochondrial Function Decline via SIRT3‐PGC1α Axis

open access: yesAdvanced Science, EarlyView.
Aged HSF1 muscle‐specific knockout mice show deteriorated muscle atrophy and metabolic dysfunction, while active HSF1 overexpression improves muscle function via activating SIRT3 to deacetylate both PGC1α1 and PGC1α4, which boosts mitochondrial function and muscle hypertrophy in a fiber‐type specific manner, and induces FNDC5/Irisin for tissue ...

ACSL5 Regulates Glucose Metabolism and Chemotherapy Sensitivity in Colorectal Cancer Cells under Glutamine Deficiency

open access: yesAdvanced Science, EarlyView.
Glutamine deprivation triggers ACSL5 upregulation in tumor cells, sustaining their viability via dual metabolic rewiring programs. ACSL5 enhances glycolysis by relieving p53's inhibition of PGAM1 while also sustaining mitochondrial respiration and TCA cycle flux through promoting IDH2 dimerization.
