WebParkin has a recognized role in mitophagy and quality control in the mitochondria (Pickrell & Youle, 2015). However, Parkin-deficient mice exhibit a different phenotype than that in humans, causing late-onset PD (Noda et al., 2024; Paul & Pickrell, 2024), possibly because laboratory mice are typically housed in specific-pathogen-free ... WebCoordination of phosphorylation and ubiquitination by the protein kinase PINK1 and the E3 ligase parkin provides a robust and tightly regulated pathway that responds to oxidative stress and creates a signal to control mitochondrial damage.
WebParkin sequestration and parkin-suppressed cell death may go hand in hand, supporting a potential role for cell toxicity mediated by protein aggregation or aberrant UPS function … WebMitophagy is an important mitochondrial quality control mechanism that eliminates damaged mitochondria. In mammals, the mitophagy pathway involves PTEN-induced putative …
WebIn the present study, we show that PLC signaling is altered in parkin deficient human neuroblastoma cell lines, resulting in a distrupted [Ca 2+] homeostasis and increased vulnerability to 6OHDA. We further show that blocking of PLC activity or Ryanodine receptors (RyR) could reverse these effects. WebUnit 6 Topic 1 Annotations: The Basics of Cell Signaling Cell Signaling Basics Cell signaling consists of three stages: reception, transduction, and response. Reception Reception involves the target cell's detection of a signal molecule coming from outside the cell, while transduction involves the conversion of the signal to a form that can cause a …
