An AI-guided screen identifies probucol as an enhancer of mitophagy through modulation of lipid droplets

PLoS Biology, 2023
Failures in mitophagy, a process by which damaged mitochondria are cleared, results in neurodegeneration, while enhancing mitophagy promotes the survival of dopaminergic neurons.

Mechanosensitive Piezo1/Osteocalcin/Irisin Axis Protects Against Disuse‐Induced Muscle Atrophy

Advanced Science, EarlyView.
Mechanical unloading suppresses bone Piezo1 expression, which reduces circulating undercarboxylated osteocalcin (unOCN). unOCN reduction subsequently exacerbates IMM‐induced Fndc5/Irisin decrease and drives severe muscle atrophy. Bone Piezo1 activation or exogenous osteocalcin/Irisin ameliorate muscle atrophy, while muscle‐specific Gprc6a or Fndc5 ...

Mitophagy in intracerebral hemorrhage: a new target for therapeutic intervention

Neural Regeneration Research
Intracerebral hemorrhage is a life-threatening condition with a high fatality rate and severe sequelae. However, there is currently no treatment available for intracerebral hemorrhage, unlike for other stroke subtypes.

Progress in research on mitophagy and pulmonary diseases [PDF]

Jichu yixue yu linchuang, 2020
Mitophagy is one of the important forms of selective autophagy, which affects the occurrence and development of lung diseases by regulating the quality of mitochondria in vivo. Mitophagy has different functions in different lung diseases.

NET‐DNA Activates the ANXA2/TMEM215/BiP Axis to Promote Mitophagy‐Mediated Anoikis Resistance in Endometriosis

Advanced Science, EarlyView.
NET‐DNA is enriched during early endometriotic lesion establishment and drives anoikis resistance by promoting an ANXA2–TMEM215–BiP axis. This pathway strengthens ER–mitochondria contacts, enhances PINK1/Parkin‐associated mitophagy, preserves mitochondrial homeostasis, and supports ectopic stromal cell survival, thereby facilitating lesion persistence ...

Activation of NIX-mediated mitophagy by an interferon regulatory factor homologue of human herpesvirus

Nature Communications, 2019
Impaired removal of damaged mitochondria by mitophagy can activate innate immune signaling, but impact on virus replication remains unclear. Here the authors show that viral IRF-1 of human herpesvirus 8 activates mitophagy via interaction with the ...

Synthetic Quantitative Array Technology Identifies the Ubp3-Bre5 Deubiquitinase Complex as a Negative Regulator of Mitophagy

Cell Reports, 2015
Mitophagy is crucial to ensuring mitochondrial quality control. However, the molecular mechanism and regulation of mitophagy are still not fully understood.

Drug‐Induced Cuproptosis Defines the Therapeutic Window of Celecoxib in Intervertebral Disc Degeneration via the HSP90‐RBX1 Axis

Advanced Science, EarlyView.
This study reveals the dual role of celecoxib in intervertebral disc degeneration. While low concentrations are protective, high concentrations induce toxicity by upregulating HSP90, which synergizes with USP15 to deubiquitinate and stabilize RBX1. This leads to degradation of COMMD1/ATP7B, copper dyshomeostasis, and ultimately, cuproptosis.

Orchestrated Engineered Polyphenol‐Peptide Condensates Coupled With β‐GP Reverses Diabetic Osteoporosis by Remodeling Mitophagy

Advanced Science, EarlyView.
A multifunctional β‐GP@EGCG‐E7 nanoplatform is engineered by polyphenol–peptide condensation and phosphate loading. Bone‐targeted delivery, antioxidant and anti‐inflammatory activity, and mitophagy restoration are integrated in one system, enabling protection of osteoblasts and endothelial cells and promoting bone regeneration under diabetic ...

Perilipin‐2‐Anchored Lipid Droplet‐Targeting Phototheranostics

Angewandte Chemie, EarlyView.
This study reports two NIR theranostic dyes, C‐BDP‐OH and C‐BDP‐OMe. C‐BDP‐OMe targets lipid droplets via a dual‐anchoring mechanism with PLIN2, enabling wash‐free tumor imaging. With 62.6% photothermal conversion efficiency, it achieves tumor ablation by downregulating PLIN2, disrupting LD‐mitochondria crosstalk, and triggering apoptosis and ...
