Balanced Expression of the Diiron Oxygenase BioE Is Essential for Biotin Homeostasis in Elizabethkingia meningoseptica

open access: yesAdvanced Science, EarlyView.
BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.

Temporal Transcriptional Regulation of Human Neuronal Differentiation via Forward Programming

open access: yesAdvanced Science, EarlyView.
Single‐cell profiling of TF‐induced forward programming versus stepwise dual‐SMAD differentiation reveals that divergent trajectories set the pace of neurogenesis. OLIG TFs advance cell‐cycle exit via NOTCH modulation, while NEUROD2 later accelerates maturation. The study elucidates transcriptional mechanisms governing differentiation timing, providing

FXYD3 Promotes Tumor Progression by Binding With IRF7 to Regulate JAK2/STAT5 Signaling in Intrahepatic Cholangiocarcinoma

open access: yesAdvanced Science, EarlyView.
FXYD3 binds IRF7 via its 60–87aa domain, triggering a cGAS/STING‐mediated positive feedback loop amplified by type I interferon. This sustains JAK2/STAT5 activation, accelerating ICC progression. Targeting FXYD3 with siFXYD3@PEP suppresses tumors and enhances chemotherapy sensitivity. Abstract Intrahepatic cholangiocarcinoma (ICC) has a poor prognosis,

Spatially Resolved Mapping of Voltage‐Gated Proton Channel Activity Reveals Delayed Proton Transport in Local Microenvironments

open access: yesAdvanced Science, EarlyView.
A revolutionary imaging platform integrating quantitative single‐molecule photobleaching with ratiometric fluorescence probes enables high‐throughput (≈2300 individually resolvable channels) mapping of individual proton channels in a large field (≈3000 µm2), overcoming the spatial and temporal limitations of conventional electrophysiology.

Piezo1 Upregulation in Monocyte‐Derived Macrophages Impairs Post‐Myocardial Infarction Cardiac Repair via Defective Efferocytosis and Enhanced Ferroptosis

open access: yesAdvanced Science, EarlyView.
This study reports early Piezo1 activation in bone marrow monocyte‐derived macrophages (MoMs) during myocardial infarction (MI), which governs the fate and function of recruited macrophages. The recruited MoMs with increased Piezo1 expression exhibit increased ferroptosis and defective efferocytosis, delayed clearance of dead cells and resolution of ...

Universal Regulation of DNA Polymerase via Photocaged Primer Enables Light‐Start Isothermal Amplification on Demand

open access: yesAdvanced Science, EarlyView.
A simple and general photoactivatable approach is developed to regulate DNA polymerase activity, enabling light‐start isothermal amplification on demand. The molecular dynamics simulations reveals that the photocaged primer blocks DNA polymerase activity by inhibiting the conformational change of the polymerase.

Molecular Insights into Fungal Glycosylphosphatidylinositol Transamidase Complex

open access: yesAdvanced Science, EarlyView.
The glycosylphosphatidylinositol (GPI) biosynthesis pathway is critical for antifungal drug development. This study reports three cryo‐electron microscopy structures of fungal GPI transamidase (GPIT), captured in two substrate‐bound states and a novel dimeric assembly.

Promoting Autophagy Mitigates Stress‐Induced Remodeling in Patient iPSC‐CMs with the Phospholamban R9C Mutation

open access: yesAdvanced Science, EarlyView.
The Phospholamban (PLN) R9C mutation reduces SERCA2a binding, increasing calcium recycling and baseline contractility. However, the excess of free PLN promotes pentamer formation, limiting phosphorylation and blunting β‐adrenergic signaling. Under cardiac stress, enhanced functional demands overwhelm proteostasis in PLN R9C cells, leading to misfolded ...
