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

Advanced 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.

KRAS Withdrawal in Cholangiocarcinoma Leads to Immune Infiltration and Tumor Regression

Advanced Science, EarlyView.
Cholangiocarcinoma (CCA) driven by oncogenic KRAS depends on its continuous activation for tumor maintenance. Using a conditional KRAS model, the authors show that turning off KRAS triggers rapid tumor regression accompanied by immune cell infiltration and cytokine release. The findings uncover a KRAS–senescence–immune signaling axis and highlight KRAS

Induced Proprioceptor and Low‐Threshold Mechanoreceptor Neurons Derived from Human Pluripotent Stem Cells Exhibit Distinct Functional Mechanosensory Properties

Advanced Science, EarlyView.
This study describes derivation of two distinct mechanosensory subpopulations from human pluripotent stem cells using a transcription factor mediated approach. Of significance, functional interrogation of induced mechanosensory subtypes reveal their unique responses to mechanical stimulation in the absence of end‐organs.

Regulating the antibiotic drug release from ß-tricalcium phosphate ceramics by atmospheric plasma surface engineering [PDF]

, 2016
Calcium phosphate (CaP) ceramics are of interest in bone substitution due to their good biocompatibility and bioresorbability. Currently certain CaPs in the market are loaded with antibiotics in order to prevent infections but further control is needed ...

Extracellular Vesicles of Streptococcus anginosus Mediate Gastritis via Epithelial Barrier Disruption and Macrophage‐driven Inflammation

Advanced Science, EarlyView.
Streptococcus anginosus extracellular vesicles (SA‐EVs) accumulate in gastric tissue, disrupt epithelial tight junctions, and induce gastritis characterized by neutrophil infiltration and elevated cytokines (TNF‐α, IL‐6, IL‐17A). Proteomics identifies TMPC and FBP62 as key SA‐EVs virulence factors; their genetic deletion attenuates inflammation ...
