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 ...

Neoeriocitrin Targeting Beclin1 Deubiquitination and Autophagy in Osteogenic Differentiation of Human Dental Pulp Stem Cells

open access: yesAdvanced Science, EarlyView.
Neoeriocitrin enhances osteogenesis in hDPSCs and bone regeneration by targeting Beclin1 to inhibit ubiquitination‐mediated degradation, thereby stabilizing Beclin1 and increasing its protein abundance to activate autophagy. Abstract Human dental pulp stem cells (hDPSCs) are dental‐derived mesenchymal stem cells with robust multipotent differentiation ...

Optimized Monothiol Thioredoxin Derivative (ORP100S) Protects In Vitro and In Vivo from Radiation and Chemotoxicity Without Promoting Tumor Proliferation

open access: yesAdvanced Science, EarlyView.
Native thioredoxin‐1 (TRX) stimulates proliferation and rescues stem cells and cancer cells from multiple stressors by suppressing p53 and inhibiting ferroptosis via GPX4/SLC7A11 upregulation mediated by enhanced KLF4 expression and p53 promoter binding.

Microwave‐Activated Bacterial Biorobot for Multimodal Cancer Therapy

open access: yesAdvanced Science, EarlyView.
An Escherichia coli bacterial biorobot is engineered for localized microwave activation in cancer therapy. Upon activation at tumor sites, the biorobot releases glucose oxidase, inducing tumor cell death via glucose depletion and H2O2 generation catalyzed by Cu2O.

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.

Restoring Histone Acetylation Accelerates Diabetic Wound Repair by Improving the Spatiotemporal Dynamics of Macrophages

open access: yesAdvanced Science, EarlyView.
Butyrate—via epigenetic modulation of the histone core—rebalance dysregulated macrophage function and promotes wound healing under persisting hostile conditions of diabetic mice. Additionally, butyrate harmonizes macrophage interactions with keratinocytes and fibroblasts as well as breaks the vicious cycle of inflammation in chronic wounds by restoring

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.

SIRT6 Lysine‐Demyristoylates ATF2 to Ameliorate Vascular Injury via PRKCD/VE‐Cadherin Pathway Regulating Vascular Endothelial Barrier

open access: yesAdvanced Science, EarlyView.
A novel modified SIRT6 variant (dSIRT6) H133Y‐mediated enrichment technique unmasks 15 new human lysine‐myristoylated proteins. Notably, Sirtuin 6 (SIRT6) demyristoylation of activating transcription factor 2 (ATF2) at K296 orchestrates its nucleoplasmic translocation.

CircSMEK1 Suppresses HCC via the hnRNPK‐IGF2‐AKT Axis: A Diagnostic Biomarker and Therapeutic Target

open access: yesAdvanced Science, EarlyView.
CircSMEK1 is downregulated in MASH/HCC and predicts poor prognosis. It suppresses tumor progression by promoting hnRNPK ubiquitination and inhibiting the IGF2/PI3K/AKT axis, while its loss activates immunosuppressive cancer‐associated fibroblasts. Serum circSMEK1 serves as a non‐invasive diagnostic biomarker, and its restoration potently inhibits HCC ...
