PARKIN is not required to sustain OXPHOS function in adult mammalian tissues

npj Parkinson's Disease
Loss-of-function variants in the PRKN gene encoding the ubiquitin E3 ligase PARKIN cause autosomal recessive early-onset Parkinson’s disease (PD). Extensive in vitro and in vivo studies have reported that PARKIN is involved in multiple pathways of ...

Fzd7 Restrains Pink1‐Dependent Mitophagy in Suture Stem Cells to Maintain Cranial Suture Patency

Advanced Science, EarlyView.
How suture stem cells fail to preserve cranial suture patency remains incompletely understood. Integrated single‐cell and high‐resolution spatial transcriptomic analyses identify reduced Fzd7 expression in Prrx1+ suture stem cells as an early feature of craniosynostosis.

Parkinson's disease-associated parkin colocalizes with Alzheimer's disease and multiple sclerosis brain lesions

Neurobiology of Disease, 2009
Parkin is implicated in the pathogenesis of Parkinson's disease. Furthermore, parkin targets misfolded proteins for degradation and protects cells against various forms of cellular stress, including unfolded-protein and oxidative stress.

Arrestin‐3 binds parkin and enhances parkin‐dependent mitophagy

Journal of Neurochemistry
Abstract Arrestins were discovered for their role in homologous desensitization of G‐protein‐coupled receptors (GPCRs). Later non‐visual arrestins were shown to regulate several signaling pathways. Some of these pathways require arrestin binding to GPCRs, the regulation of others is receptor independent.

CDK4/MERCs/PINK1 Axis Drives PFOA/HFPO‐TA‐Induced Cardiac Senescence via Mitophagy Defect and cGAS‐STING Activation: In Vitro Amelioration by Cycloastragenol

Advanced Science, EarlyView.
The present study demonstrated that PFOA and HFPO‐TA exposure suppressed CDK4, disrupted MERCs and impaired PINK1/Parkin‐mediated mitophagy, thereby accelerating cardiac senescence, whereas CAG effectively reversed these pathological changes in vitro. Our findings identify CDK4 as a critical regulator bridging mitophagy defects and cardiac senescence ...

Stabilization of Ultrafast Domain Wall Motion by Edge‐Anisotropy Engineering in Ferrimagnetic Nanowires

Advanced Electronic Materials, EarlyView.
Localized laser annealing transforms distorted, edge‐pinned domain‐wall motion in ferrimagnetic Pt/GdFe nanowires into straight, stable, and ultrafast propagation. Experiments and micromagnetic simulations reveal an optimum anisotropy‐engineering window in which moderate edge softening suppresses pinning, whereas excessive anisotropy reduction or ...

Natural Anionic Interfacial Reconstruction for Suppressing Pitting Corrosion Enables Durable Seawater Zinc‐Ion Batteries

Advanced Energy Materials, EarlyView.
In situ electrochemically induced molecular sieve‐alginate interface layer can suppress chloride‐induced pitting corrosion, hydrogen evolution, and dendrite growth, while regulating zinc ion transport and deposition, thereby protecting the zinc anode in seawater electrolyte.

Altered Mitochondrial Respiration and Other Features of Mitochondrial Function in Parkin-Mutant Fibroblasts from Parkinson’s Disease Patients

Parkinson's Disease, 2016
Mutations in the parkin gene are the most common cause of early-onset Parkinson’s disease (PD). Parkin, an E3 ubiquitin ligase, is involved in respiratory chain function, mitophagy, and mitochondrial dynamics.

Single‐cell atlas of neuroglial dynamics in SNCA‐A53T Parkinson's disease mouse model

Animal Models and Experimental Medicine, EarlyView.
We performed single‐cell RNA sequencing of midbrain and striatal tissues from SNCA‐A53T Parkinson's disease (PD) mice, revealing glia‐enriched PD‐risk gene signatures and disease‐specific subpopulations. Transcriptional dysregulation of key TFs (e.g., Rorb, Foxc1) and enhanced neuroinflammatory signaling (SEMA, CCL, MIF) were identified.

Parkin Sensitizes toward Apoptosis Induced by Mitochondrial Depolarization through Promoting Degradation of Mcl-1

Cell Reports, 2014
Mitochondrial depolarization promotes Parkin- and PTEN-induced kinase 1 (PINK1)-dependent polyubiquitination of multiple proteins on mitochondrial outer membranes, resulting in the removal of defective mitochondria via mitophagy. Because Parkin mutations
