PCSK9 Loss‐of‐Function Disrupts Cellular Microfilament Network via LIN28A/HES5/JMY Axis in Neural Tube Defects

open access: yesAdvanced Science, EarlyView.
PCSK9 acts as a molecular chaperone promoting LIN28A lysosomal degradation. LIN28A elevates transcription factor HES5, increasing JMY expression. PCSK9 loss causes neural tube defects (NTDs) by disrupting the LIN28A/HES5/JMY axis, and high JMY disorganizes the neural progenitor cell microfilament network, leading to incomplete neural tube structure in ...

NEAT1 Promotes Epileptogenesis in Tuberous Sclerosis Complex

open access: yesAdvanced Science, EarlyView.
The primary neurological manifestations of tuberous sclerosis complex (TSC) are intractable epilepsy and intellectual disability. NEAT1 is differentially expressed in TSC‐related epilepsy and influences neuronal excitability by regulating the PI3K/AKT/mTOR signaling pathway.

Snord15b Maintains Stemness of Intestinal Stem Cells via Enhancement of Alternative Splicing of Btrc Short Isoform for Suppression of β‐Catenin Ubiquitination

open access: yesAdvanced Science, EarlyView.
In intestinal stem cells (ISCs), Snord15b associates with Ilf2 to recruit splicing factors for alternative splicing of Btrc mRNA, leading to the generation of short Btrc. This short Btrc fails to form a functional E3 ubiquitin ligase complex for β‐catenin ubiquitination and degradation.

Arginine Metabolic Disruption Impairs Hair Regeneration via ROS‐Mediated Inactivation of mTOR Signaling in Androgenetic Alopecia

open access: yesAdvanced Science, EarlyView.
Arginine deficiency accelerates androgenetic alopecia. Serum metabolome shows reduced circulating arginine, while local metabolic disruption depletes follicular reserves, triggering reactive oxygen species (ROS) accumulation and mTOR suppression that induce hair miniaturization.

Sympathetic Activation Promotes Kidney Fibrosis in Mice via Macrophage‐Derived N2ICD‐Enriched Extracellular Vesicles

open access: yesAdvanced Science, EarlyView.
Norepinephrine/α2B‐adrenoceptor axis promotes the secretion of Notch2 intracellular domain (N2ICD)‐enriched extracellular vesicles (EVs) from macrophages. These EVs deliver N2ICD into fibroblasts, thereby inducing their activation. Deletion of Notch2 or α2B‐AR in macrophages disrupts N2ICD‐enriched EV formation and alleviates kidney fibrosis in mice ...

GSK461364 Inhibits NLRP3 Inflammasome by Targeting NEK7 Phosphorylation

open access: yesAdvanced Science, EarlyView.
Schematic diagram of the mechanism by which GSK461364 inhibits NLRP3 inflammasome activation. GSK461364 inhibits the phosphorylation of NEK7 likely at serine 221 and serine 260 by suppressing the activity of PLK1, thereby restraining the formation of the NLRP3 inflammasome.

Lactylation of HMGB1 at K177 Drives Nuclear Export of TIAR to Promote Hypoxia‐Induced Stress Granule Formation

open access: yesAdvanced Science, EarlyView.
This study uncovers a novel mechanism in which p300‑catalyzed lactylation of HMGB1 triggers nuclear export of the HMGB1‐TIAR complex, driving TIAR‐dependent SGs formation in the cytoplasm. Mass spectrometry and mutagenesis reveals that K177 lactylation is essential for this export and subsequent SGs formation.

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.

Targeting eRNA‐Producing Super‐Enhancers Regulates TNFα Expression and Mitigates Chronic Inflammation in Mice and Patient‐Derived Immune Cells

open access: yesAdvanced Science, EarlyView.
Targeting eRNAs from TNFα‐associated super‐enhancers with ASOs effectively reduces TNFα expression and inflammatory responses in both mouse models and patient‐derived immune cells. The conserved nature of these regulatory regions between species highlights the potential of eRNA‐targeted approaches as a therapeutic strategy for chronic inflammatory ...

Preservation of ALYREF Phase Separation Mitigates Doxorubicin‐Induced Cardiomyocyte DNA Damage and Cardiotoxicity

open access: yesAdvanced Science, EarlyView.
Binding of Doxorubicin to ALYREF disrupts its phase‐separated condensate and induces DNA damage and apoptosis in cardiomyocytes Abstract The clinical utility of the anticancer agent doxorubicin (DOX) is limited by its dose‐dependent cardiotoxicity.
