Stochastic Nanoscale Biophysical Cues as a Basis for the Induction of Glioblastoma‐Like Transcriptional Programs in Astrocytes

Advanced Science, EarlyView.
Stochastic nanoscale physical cues induce glioblastoma (GBM)‐associated transcriptional traits in naïve astrocytes leading to spontaneous formation of spheroids. Cells within spheroids express activated‐MMP2 and a differential gene expression pattern involving P53 and NOTCH3, providing evidence for a role for changes in brain topography, as observed in

Thiamine Acquisition Strategies Impact Metabolism and Competition in the Gut Microbe Bacteroides thetaiotaomicron. [PDF]

, 2017
Thiamine (vitamin B1) is an essential cofactor for all organisms. Humans primarily acquire thiamine through their diet, and thiamine deficiencies have adverse neurological effects.

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.

A Mussel‐Inspired Bioadhesive Patch to Selectively Kill Glioblastoma Cells

Advanced Science, EarlyView.
An innovative mussel‐inspired bioadhesive patch has been developed for post‐surgical glioblastoma treatment. The patch, which adheres strongly in biological environments, releases a localized treatment. This treatment, acting via reactive oxygen species, shows specific toxicity to glioblastoma cells.

Biogenesis of cytochrome c1 [PDF]

, 1989
The biogenesis of cytochrome c1 involves a number of steps including: synthesis as a precursor with a bipartite signal sequence, transfer across the outer and inner mitochondrial membranes, removal of the first part of the presequence in the matrix ...

The Disordered Region of ASXL1 Acts as an Auto‐Regulator Through Condensation

Advanced Science, EarlyView.
ASXL1's long IDR encodes an electrostatic “basic platform + acidic brake” that autoregulates condensation. Truncation at a clinical hotspot lifts this brake, forming condensates that retarget BRD2, remodel local chromatin accessibility, and impair neutrophil maturation.

Inhibiting heme piracy by pathogenic Escherichia coli using de novo-designed proteins

Nature Communications
Iron is an essential nutrient for most bacteria and is often growth-limiting during infection, due to the host sequestering free iron as part of the innate immune response.

Domestication of Tartary Buckwheat Shaped a Regulatory Module for Seedling Salt Tolerance by Targeting the Magnesium Transporter Gene FtMGT2

Advanced Science, EarlyView.
Domestication of Tartary buckwheat is selected for a salt tolerance mechanism involving the magnesium transporter FtMGT2. Its expression is controlled by the FtAGL16‐FtMYB15L module, which is stabilized under salt stress through a competitive interaction that blocks its degradation by the E3 ligase FtBRG1, ultimately boosting Na⁺ efflux and plant ...

Beyond Catalytic Therapy: Copper‐Paeonol Nanozymes Disrupt Fascin‐Mediated Actin Bundling to Suppress Tumor Growth and Metastasis

Advanced Science, EarlyView.
Copper‐paeonol nanozymes target tumor‐specific reactive oxygen species generation and disrupt fascin‐mediated actin bundling, effectively suppressing tumor growth and metastatic colonization. Abstract Fascin, an actin‐bundling protein universally upregulated in metastatic tumors, drives tumor migration and invasion by promoting filopodia and ...
