SLC2A3‐Mediated Lactate Metabolism Promotes Lung Cancer Bone Metastasis by Modulating P53 Lactylation and Immune Evasion

Advanced Science, EarlyView.
SLC2A3 derived lactate promotes metastasis through p53 lactylation at K120 and osteoclast differentiation. Pharmacological inhibition of SLC2A3 upregulates PD‐1 expression on CD8+ T cells via lactate induced p53 lactylation, which modulates immune evasion. ABSTRACT Bone metastasis is a devastating consequence of lung cancer.

X-ray structure of a carpet-like antimicrobial defensin–phospholipid membrane disruption complex

Nature Communications, 2018
Defensins are cationic antimicrobial peptides that permeabilize membranes of pathogens presumably via the assembly of defensin–lipid oligomers. Here authors provide evidence for this by solving the crystal structure of a plant defensin in an oligomeric ...

The Role of Cationic Polypeptides in Modulating HIV-1 Infection of the Cervicovaginal Mucosa

Antibiotics, 2014
The mucosa and overlying fluid of the female reproductive tract (FRT) are portals for the heterosexual transmission of HIV-1. Toward the ongoing development of topically applied microbicides and mucosal vaccines against HIV-1, it is evermore important to

A Glucose‐Responsive Intelligent Antibacterial and Oxygen‐Producing Hydrogel Promotes the Healing of Diabetic Wounds by Regulating Cellular Heterogeneity

Advanced Science, EarlyView.
We have developed a glucose‐triggered on‐demand drug delivery CF‐CPGaMPN hydrogel based on borate ester bonds. It inactivates microbes, releases oxygen, and enables on‐demand drug release in high‐glucose environments to promote healing of diabetic wounds. Single‐cell sequencing reveals that the CF‐CPGaMPN hydrogel significantly alleviates dysfunctional

Potent cationic antimicrobial peptides against Mycobacterium tuberculosis in vitro

Journal of Global Antimicrobial Resistance, 2019
Tuberculosis (TB) is known to be one of the 10 causes of global death by infectious agents. The increasing numbers of multiple antibiotic resistance (MDR-TB) and cases of extensive resistance to antibiotics (XDR-TB) have led to the development of new and effective TB therapy.

Precise Construction of an Antimicrobial Peptide Targeting Bacterial Cell Membranes Derived From Natural Peptides

Advanced Science, EarlyView.
An AMP (P 3‐3R‐8I) based on natural peptides, which can target bacterial cell membranes, was precisely constructed via amino acid mutation. P 3‐3R‐8I exhibits antibacterial capability which could be attributed to the ability of P 3‐3R‐8I to quickly penetrate bacterial cell membranes and then to bind to bacterial DNA.

Detergent-like actions of linear amphipathic cationic antimicrobial peptides

Biochimica et Biophysica Acta (BBA) - Biomembranes, 2006
Antimicrobial peptides have raised much interest as pathogens become resistant against conventional antibiotics. We review biophysical studies that have been performed to better understand the interactions of linear amphipathic cationic peptides such as magainins, cecropins, dermaseptin, delta-lysin or melittin.

Targeted H2S Delivery System Attenuates Blood‐Spinal Cord Barrier Disruption after Spinal Cord Injury by Reshaping the Ferritinophagy Pathway

Advanced Science, EarlyView.
The αvβ3‐mediated SPRC@MPDA‐RGD targets broken endothelial cells and controllably releases SPRC. CSE is then activated to produce endogenous H2S, which inhibits ferritinophagy. In brief, H2S inhibits autophagy by activating the PI3K/Akt/mTOR pathway, thereby suppressing the ferroptosis process mediated by NCOA4, and ultimately promoting the ...

DOTA‐grafted Cationic Polymers Behaving as Powerful Macromolecular Resistance‐reversal Agents (MRRAs) Combating Against New Delhi Metallo‐β‐lactamase (NDM)‐producing Bacteria

Advanced Science, EarlyView.
Two macromolecular resistance‐reversal agents (MRRAs)—linear (MRRAL) and nanostructured (MRRAN) polymers were fabricated by integrating DOTA motifs into tunable polycationic scaffolds. MRRAs exhibit superior antibacterial potency once combined with meropenem (MEM) through (i) bacterial membrane disruption via localized cationic charge and ...
