AMPK/PGC-1α and p53 modulate VDAC1 expression mediated by reduced ATP level and metabolic oxidative stress in neuronal cells

Acta Biochimica et Biophysica Sinica
Voltage-dependent anion channel 1 (VDAC1) is a pore protein located in the outer mitochondrial membrane. Its channel gating mediates mitochondrial respiration and cell metabolism, and it has been identified as a critical modulator of mitochondria ...

Ammonia Accumulation Drives Intervertebral Disc Degeneration by Triggering Ammonia‐Induced Cell Death Through Lysosome–Mitochondria Crosstalk

Cell Proliferation, EarlyView.
Mechanical strain disrupts the lysosome‐mitochondria axis via GLS1‐mediated ammonia toxicity, causing NP cell death and ECM breakdown in IVDD. CB839‐mediated GLS1 inhibition effectively rescues cellular homeostasis and alleviates disc degeneration.

Role of VDAC1 hypoxic form, VDAC1-∆C, in the expression of primary cilia and tumor progression

, 2019
Le voltage-dependent anion channel 1 (VDAC1) est une porine exprimée au niveau de la membrane externe des mitochondries et qui joue un rôle très important dans la régulation du métabolisme cellulaire et de l'apoptose. En condition d’hypoxie (c'est-à-dire

Flexibility of the N-Terminal mVDAC1 Segment Controls the Channel’s Gating Behavior [PDF]

, 2012
Since the solution of the molecular structures of members of the voltage dependent anion channels (VDACs), the N-terminal α-helix has been the main focus of attention, since its strategic location, in combination with its putative conformational ...

Arsenite methyltransferase 3 is required for mitochondrial function and hepatic lipid metabolism

The FEBS Journal, EarlyView.
AS3MT is a protein that helps the body process arsenic, a naturally occurring toxin found in water and soil. We discovered it also helps cells make and use energy properly. Without AS3MT, cells' mitochondria do not work well, leading to fatty liver and reduced activity. Increasing AS3MT in liver cells restores energy and protects against arsenic damage,

Rôle de la forme hypoxique VDAC1, VDAC1-∆C, dans l’expression du cil primaire et la progression tumorale

, 2019
Voltage-dependent anion channel1 (VDAC1) is a porin of the mitochondrial outer membrane that plays a very important role in the regulation of cellular metabolism and apoptosis. As a consequence of hypoxia (i.e.

G6PD maintains the VSMC synthetic phenotype and accelerates vascular neointimal hyperplasia by inhibiting the VDAC1–Bax-mediated mitochondrial apoptosis pathway

Cellular & Molecular Biology Letters
Background Glucose-6-phosphate dehydrogenase (G6PD) plays an important role in vascular smooth muscle cell (VSMC) phenotypic switching, which is an early pathogenic event in various vascular remodeling diseases (VRDs).

Selective autophagy pathways in ageing and neurodegeneration: Emerging roles for mitophagy and nucleophagy

The FEBS Journal, EarlyView.
As we age, cells gradually accumulate damage, which can contribute to disease and neurodegeneration. This review explores how two cellular recycling processes, mitophagy and nucleophagy, remove damaged mitochondria and nuclear material, respectively, to maintain cell health and long‐term neuronal homeostasis.

Bakuchiol: From structural mimicry to systems‐level skin biology

International Journal of Cosmetic Science, EarlyView.
Convergent outcomes, divergent mechanisms: bakuchiol vs. retinol. Bakuchiol exhibits functional convergence with retinol in improving extracellular matrix integrity, epidermal differentiation and barrier function, while operating through distinct mechanisms.

Hypercapnia Induces Mitochondrial Adaptations and Alters Glutamine Metabolism to Drive a Distinct Metabolic Phenotype in Monocytes

Immunology &Cell Biology, EarlyView.
Elevated CO2 (hypercapnia) is a feature of serious lung diseases, for example COPD and contributes to poor patient prognosis through modulation of immune cell function. Here we employ state‐of‐the art metabolomic and isotope tracing approaches to reveal CO2‐dependent mitochondrial alterations linked to suppressed ATP, proline and glutamate levels in ...
