Phosphorylation of Parkin at serine 65 is essential for its activation in vivo [PDF]

Open Biology, 2018
Mutations in PINK1 and Parkin result in autosomal recessive Parkinson's disease (PD). Cell culture and in vitro studies have elaborated the PINK1-dependent regulation of Parkin and defined how this dyad orchestrates the elimination of damaged ...

Role of Cleaved PINK1 in Neuronal Development, Synaptogenesis, and Plasticity: Implications for Parkinson’s Disease

Frontiers in Neuroscience, 2021
Mitochondrial dysfunction plays a significant role in the pathogenesis of Parkinson’s disease (PD). Consistent with this concept, loss of function mutations in the serine/threonine kinase- PINK1 (PTEN-induced putative kinase-1) causes autosomal recessive

PINK1, cancer and neurodegeneration

Oncoscience, 2016
Cancer and neurodegeneration are two age-related diseases that arise from aberrant signaling in similar cellular systems, those that balance survival and death. Thus, deregulated molecular processes such as DNA damage repair, intracellular energy balance, and key signal transduction systems, including the PI3-kinase/Akt axis can promote tumorigenesis ...

Mechanism of parkin activation by PINK1 [PDF]

Nature, 2018
Mutations in the E3 ubiquitin ligase parkin (PARK2, also known as PRKN) and the protein kinase PINK1 (also known as PARK6) are linked to autosomal-recessive juvenile parkinsonism (AR-JP)1,2; at the cellular level, these mutations cause defects in mitophagy, the process that organizes the destruction of damaged mitochondria3,4.

Mitochondrial stress in advanced fibrosis and cirrhosis associated with chronic hepatitis B, chronic hepatitis C, or nonalcoholic steatohepatitis

Hepatology, EarlyView., 2022
Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

PINK1 points Parkin to mitochondria [PDF]

Autophagy, 2010
For decades, it has been presumed that mitochondrial dysfunction, in the form of impaired complex I activity, may contribute to the cause of Parkinson disease (PD). ( 1) The discovery that several gene mutations cause familial forms of PD ( 1) has led to a renewed enthusiasm for the mitochondrial hypothesis of PD, but this time from a quite distinct ...

Interaction of PINK1 with nucleotides and kinetin

Science Advances, 2023
The ubiquitin kinase PINK1 accumulates on damaged mitochondria to trigger mitophagy, and PINK1 loss-of-function mutations cause early onset Parkinson’s disease. Nucleotide analogs such as kinetin triphosphate (KTP) were reported to enhance PINK1 activity and may represent a therapeutic strategy for the treatment of Parkinson’s ...

The effect of 4 weeks of continuous aerobic training with different volumes and starvation on the expression of some genes involved in liver mitophagy in healthy male Wistar rats [PDF]

ورزش و علوم زیست حرکتی
Introduction and Purpose: An increase in the number of defective mitochondria and their persistence can lead to apoptosis and necrosis of cells. Regular physical exercise along with time-restricted eating (TRE) can play an important role in improving ...

PINK1/PARKIN signalling in neurodegeneration and neuroinflammation [PDF]

Acta Neuropathologica Communications, 2020
Abstract Mutations in the PTEN-induced kinase 1 (PINK1) and Parkin RBR E3 ubiquitin-protein ligase (PARKIN) genes are associated with familial forms of Parkinson’s disease (PD). PINK1, a protein kinase, and PARKIN, an E3 ubiquitin ligase, control the specific elimination of dysfunctional or superfluous mitochondria, thus fine-tuning ...
