Chloroplast Stress Signals Orchestrate Epidermis‐Specific Remodeling of Mitochondria and ER Under High Light

Advanced Science, EarlyView.
High light exposure triggers an epidermis‐specific remodeling of mitochondria and ER in Arabidopsis, driven by chloroplast‐derived signals. Live‐cell imaging shows that HL rapidly suppresses mitochondrial motility, followed by fusion‐driven elongation and ER cisternal expansion.

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

Inhibition of Calcium‐Dependent Lipid Droplets Relocation of ACSL4‐PKCβ‐ALOX15 Complex Alleviates Ferroptosis and Acute Pancreatitis

Advanced Science, EarlyView.
This study identifies L‐type calcium channel blockers as novel ferroptosis inhibitors. It reveals that PKCβ, activated in calcium dependent manner, phosphorylates and activates ACSL4 and ALOX15, relocating them to lipid droplets to promote lethal lipid peroxidation and ferroptosis.

Thyroid Hormone as a Method of Reducing Damage to Donor Hearts after Circulatory Arrest [PDF]

, 2017
There is a chronic lack of donor hearts to meet the need for heart transplant both in the US and worldwide. Further, the use of available hearts is limited by the short period between collection and implantation during which the heart can be safely ...

Mitochondrial heat shock protein 70, a molecular chaperone for proteins encoded by mitochondrial DNA [PDF]

, 1994
Mitochondrial heat shock protein 70 (mt-Hsp70) has been shown to play an important role in facilitating import into, as well as folding and assembly of nuclear-encoded proteins in the mitochondrial matrix.

Disulfide‐Bridged Ru Complex–Mediated Photo‐Disulfidptosis for Colorectal Cancer Therapy

Advanced Science, EarlyView.
In this work, a binuclear ruthenium complex, RuSSRu was developed for efficient colorectal cancer (CRC) treatment. The synergistic interaction between disulfidptosis and lysosomal damage‐induced apoptosis induced by RuSSRu amplified tumor cell death. This innovative approach offers a potent therapeutic strategy for CRC.

3D Bioprinted Fat‐Myocardium Model Unravels the Role of Adipocyte Hypertrophy in Atrial Dysfunction

Advanced Science, EarlyView.
A human‐derived 3D bioprinted fat–myocardium model is developed to investigate how adipocyte hypertrophy drives atrial dysfunction in obesity. Palmitate‐induced adipocyte hypertrophy promotes adipose dysfunction that impairs atrial cardiomyocyte metabolism and electrophysiology through both paracrine and direct interactions. This platform recapitulates

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 ...

Early cerebellar deficits in mitochondrial biogenesis and respiratory chain complexes in the KIKO mouse model of Friedreich ataxia

Disease Models & Mechanisms, 2017
Friedreich ataxia (FRDA), the most common recessive inherited ataxia, results from deficiency of frataxin, a small mitochondrial protein crucial for iron-sulphur cluster formation and ATP production.
