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.

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.

Reprogramming Tumor‐Associated Macrophages via Targeted NAT10 Inhibition to Enhance Colorectal Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
This study presents the sono‐sensitive nanorobot Sono@NAT10, which targets NAT10 condensates to reprogram tumor‐associated macrophages in colorectal cancer. By reducing the acetylation level of SRSF2 protein and activating HDAC10, Sono@NAT10 promotes M1 polarization, suppresses tumor progression, and strengthens immunotherapy. The approach demonstrates
