Reactive Oxygen Species-Mediated Control of Mitochondrial Biogenesis

International Journal of Cell Biology, 2012
Mitochondrial biogenesis is a complex process. It necessitates the contribution of both the nuclear and the mitochondrial genomes and therefore crosstalk between the nucleus and mitochondria. It is now well established that cellular mitochondrial content

m6A‐Driven Pexophagy Triggers Placental Ferroptosis to Impair Fetal Growth Upon Environmental Stress

Advanced Science, EarlyView.
Prenatal environmental stress exposure promotes m6A modification to drive PEX2‐dependent pexophagy, thereby causing placental ferroptosis and FGR. ABSTRACT The role and underlying mechanisms of placental ferroptosis in fetal growth restriction (FGR) induced by environmental stress remain poorly understood.

Shikonin blocks CAF-induced TNBC metastasis by suppressing mitochondrial biogenesis through GSK-3β/NEDD4-1 mediated phosphorylation-dependent degradation of PGC-1α

Journal of Experimental & Clinical Cancer Research
Background Triple-negative breast cancer (TNBC) is characterized by its high metastatic potential, which results in poor patient survival. Cancer-associated fibroblasts (CAFs) are crucial in facilitating TNBC metastasis via induction of mitochondrial ...

USP30‐Mediated Deubiquitination of PEX5 Suppresses Pexophagy to Drive Tubular Injury in Diabetic Kidney Disease

Advanced Science, EarlyView.
USP30 accumulation in diabetic renal tubular epithelial cells deubiquitinates PEX5, suppresses pexophagy, and drives dysfunctional peroxisome accumulation and tubular injury. USP30 depletion restores PEX5 ubiquitination and pexophagy, improves peroxisomal function, and alleviates tubular damage, highlighting USP30 as a therapeutic target in diabetic ...

A novel mechanism involved in the coupling of mitochondrial biogenesis to oxidative phosphorylation

, 2014
Mitochondria are essential organelles that are central to a multitude of cellular processes, including oxidative phosphorylation (OXPHOS), which produces most of the ATP in animal cells.

Lactate promotes mitochondrial biogenesis and fusion via GPR81 to enhance synaptic plasticity-related protein expression in hippocampal cells

Frontiers in Cell and Developmental Biology
BackgroundBeyond its traditional role as a glycolysis end-product, lactate is now recognized as an important signaling molecule influencing synaptic plasticity and mitochondrial activity.ObjectiveWe examined whether lactate, acting through its receptor ...

SPARC Drives Podocyte Mitochondrial Damage and Ferroptosis in Diabetic Kidney Disease Following Klotho Deficiency

Advanced Science, EarlyView.
Klotho deficiency promotes podocyte mitochondrial dysfunction and ferroptosis through activation of the PKCα/CUX1/SPARC/TGFβ‐RII axis. SPARC emerges as a key mediator linking Klotho loss to podocyte injury in DKD and other kidney injury models, suggesting broader implications for CKD progression.

Photobiomodulation‑Engineered Extracellular Vesicles Enhance Neural Differentiation via UFL1‑Mediated UFMylation in Spinal Cord Injury

Advanced Science, EarlyView.
Photobiomodulated microglia release engineered extracellular vesicles that deliver UFL1 to the injured spinal cord. UFL1 competitively binds p53 with MDM2, inhibiting p53 ubiquitination and stabilizing p53 signaling. This dual mechanism simultaneously promotes anti‐inflammatory microglial polarization and directs neural stem cell differentiation toward

METTL3-dependent m6A modification of GHR mRNA regulates mitochondrial function through mitochondrial biogenesis during myoblast differentiation

Poultry Science
N6-methyl-adenosine (m6A) methylation has recently been shown to play a critical role in muscle development. We recently revealed that local GHR knockdown impairs mitochondrial function by inhibiting mitochondrial biogenesis, thereby repressing myoblast ...
