Glycolytic Enzyme HK2 Phosphorylates nSMase1 to Promote Astrocytic Exosomes Biogenesis Contributing to Acute Ischemic Stroke Injury

open access: yesAdvanced Science, EarlyView.
This study reveals that the glycolytic enzyme HK2 mediates hypoxia‐induced astrocytic exosome biogenesis by directly phosphorylating nSMase1. These astrocytic exosomes impair brain endothelial tight junctions. Astrocyte‐specific knockdown of HK2 reduces exosome release and alleviates brain injury after MCAO.

A genetic toolkit for the analysis of metabolic changes in Drosophila provides new insights into metabolic responses to stress and malignant transformation [PDF]

open access: yes, 2019
Regulation of the energetic metabolism occurs fundamentally at the cellular level, so analytical strategies must aim to attain single cell resolution to fully embrace its inherent complexity.

Weak and Tunable Adhesion–Clutch Drives Rapid Cell Migration and Glioblastoma Invasion

open access: yesAdvanced Science, EarlyView.
This study proposes that adhesion–clutch can mediate both cell motility and immobilization depending on the force amplitude. Weak adhesion–clutch is well‐suited for cell migration, without forming strong adhesions that impede cell motility. It propels rapid dendritic cell migration controlled by extracellular chemicals, as well as pathologically ...

Editorial focus: understanding off-target effects as the key to successful RNAi therapy

open access: yesCellular & Molecular Biology Letters, 2019
With the first RNA interference (RNAi) drug (ONPATTRO (patisiran)) on the market, we witness the RNAi therapy field reaching a critical turning point, when further improvements in drug candidate design and delivery pipelines should enable fast delivery ...

Polyhalogenated Carbazole Impairs Dopaminergic Neurons through Dysregulation of Liquid–Liquid Phase Separation in Caenorhabditis elegans

open access: yesAdvanced Science, EarlyView.
Polyhalogenated carbazoles (PHCZ), persistent environmental contaminants, preferentially accumulate in neuronal tissues. Studies using Caenorhabditis elegans and human neuronal cell lines reveal that PHCZ induce dopaminergic neurodegeneration by promoting liquid–liquid phase separation of α‐synuclein, reducing condensate fluidity, impairing ...

A Study on the Cell Layer Patterns of a Citrus Periclinal Chimera Reveals β‐Cryptoxanthin Regulation in Citrus Fruits

open access: yesAdvanced Science, EarlyView.
Researchers have identified a citrus chimera with distinctive tissue origins and carotenoid profiles. It is discovered that fruit tissues develop from all three cell layers but in different proportions. A key transcription factor, MYB107, regulates β‐cryptoxanthin production by directly activating carotenoid biosynthesis genes, explaining why some ...

Use of RNAi technology to develop a PRSV-resistant transgenic papaya

open access: yesScientific Reports, 2017
Papaya ringspot virus (PRSV) seriously limits papaya (Carica papaya L.) production in tropical and subtropical areas throughout the world. Coat protein (CP)- transgenic papaya lines resistant to PRSV isolates in the sequence-homology-dependent manner ...

SENP6 Maintains Mitochondrial Homeostasis by Regulating Mitochondrial Protein Import Through deSUMOylation of TOM40

open access: yesAdvanced Science, EarlyView.
SUMOylation regulates mitochondrial processes, but its impact on protein import remains unclear. TOM40 is identified, a mitochondrial outer membrane channel protein, as a substrate of deSUMOylase SENP6. TOM40 SUMOylation disrupts outer membrane complex assembly, inhibits protein import, and compromises mitochondrial homeostasis.

Activation of Spinal Astrocyte α2A Adrenoceptors Protects Against Sepsis‐Induced Heart Injury Through Inhibition of GABAergic Neuronal Necroptosis

open access: yesAdvanced Science, EarlyView.
The study in this paper found that activating the α2A receptors of astrocytes in the thoracic spinal cord can reduce the release of inflammatory factors, thereby decreasing the necroptosis of GABAergic neurons and consequently alleviating myocardial injury caused by sepsis.

Mesenchymal Stromal Cells Play an Analgesic Role Through a Npy2r Sensory Neuron‐Mediated Lung‐to‐Brain Axis

open access: yesAdvanced Science, EarlyView.
Mesenchymal stromal cells (MSC) are considered a promising alternative for neuropathic pain (NP) treatment, but underlying mechanisms remain elusive. Huang et al. illustrate that a Npy2r sensory neuron‐related lung–brain axis contributes to MSC analgesia.
