The Natural Product Corramycin Acts as a DNA Gyrase Poison and Overcomes Fluoroquinolone Resistance in Mycobacterium tuberculosis

open access: yesAdvanced Science, EarlyView.
Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...

Human red blood cells at work: identification and visualization of erythrocytic eNOS activity in health and disease [PDF]

open access: yes, 2012
A nitric oxide synthase (NOS)-like activity has been demonstrated in human red blood cells (RBCs), but doubts about its functional significance, isoform identity and disease relevance remain.

AI Designed Conformation Locking Peptides Target STING to Restore Diabetic Wound Healing

open access: yesAdvanced Science, EarlyView.
A generative AI pipeline identifies SCP‐1, a conformation‐locking peptide that stabilizes inactive STING. Incorporated into a dual‐responsive hydrogel for localized, MMP‐9‐triggered release, SCP‐1 suppresses inflammation, promotes reparative macrophage polarization, and accelerates diabetic wound healing.

Renal Tubular Epithelial CRLF1 Interacts With ITGB1 to Accelerate Fibrosis During the Transition From AKI to CKD

open access: yesAdvanced Science, EarlyView.
During renal fibrosis, SMAD3 acts as a transcription factor for CRLF1, promoting its expression and secretion. CRLF1 then binds to ITGB1 via an autocrine mechanism, activating the PI3K‐AKT signaling pathway to mediate renal fibrosis. This accelerates the progression from AKI to CKD, highlighting the therapeutic potential of targeting CRLF1 for ...

Synergistic p53 Pathway Activation Through Sono‐Gene Therapy Induced by Ultrasound‐Triggered Theranostic Mesoporous Nanoparticles

open access: yesAdvanced Science, EarlyView.
Schematic representation of ultrasound‐mediated ICG/siCD24@MSN‐LCD from nanostructure to synergistic sono‐gene therapy. This nanoplatform targets ASGPR via the LCD shell, which dissociates to release loaded ICG and siCD24. The core mechanism involves ultrasound‐guided sonodynamic therapy by ICG and CD24 knockdown by siCD24, both activating the p53 axis

TRIM28‐Derived Peptide Exerts Anti‐Tumor Roles by Stabilizing Tumor Suppressive BRD7 Protein in Multiple Cancers

open access: yesAdvanced Science, EarlyView.
An α‐helical peptide, TAB12, designed to mimic the TRIM28 binding interface, competitively disrupts the TRIM28‐BRD7 interaction, thereby blocking ubiquitin‐mediated degradation of the tumor suppressor BRD7. This stabilization unleashes potent anti‐tumor effects across multiple tumor types with a favorable safety profile, offering a feasible strategy ...

A prescription-based model for predicting post-hemodialysis urea and electrolytes: a real-world validation study in acute hemodialysis

open access: yesBMC Nephrology
Background Urgent-start hemodialysis often involves severe biochemical abnormalities but is associated with a high risk of complications. Currently, no tool has been validated to predict post-hemodialysis urea and electrolytes in acute settings from ...

DDX3x Regulates NINJ1 Transcription via Histone Lactylation in Sepsis Associated‐Acute Kidney Injury

open access: yesAdvanced Science, EarlyView.
This study identifies a potential therapeutic approach for sepsis‐associated acute kidney injury (SA‐AKI). We found that during SA‐AKI, reduced expression of DDX3x in renal tubular epithelial cells mediates histone delactylation, which in turn upregulates NINJ1 transcription and triggers tubular cell death. Conversely, Odetiglucan confers protection by

Urea-Loaded Core–Shell MOF/Silica Nanocarriers for Continuous Nitrogen Release to Crops

open access: yes
Nitrogen is currently the most crucial nutrient for crop growth, and the overdose of conventional urea nitrogen fertilizer has resulted in both the waste of fertilizer resource and the eutrophication of water bodies due to low nitrogen use efficiency ...
