An Aggregation‐Induced Polymerization Poly(Disulfide)‐Drug Nanoplatform for Autoimmune Uveitis Therapy via Inhibiting the cGAS‐STING Pathway

Advanced Science, EarlyView.
A cationic poly(disulfide)‐drug nanoplatform (LA/DexP) was developed to treat experimental autoimmune uveitis (EAU). With potent blood‐retinal barrier penetrability, LA/DexP releases DSP in response to high ROS and scavenges cfDNA to inhibit the cGAS‐STING signaling pathway.

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

Advanced 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 ...

Scalable Separation and Purification of M13‐Bacteriophage‐Derived Particles Containing Artificial Single‐Stranded DNA Produced by Escherichia coli

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Single‐stranded DNA (ssDNA) solutions are promising innovations shaping the future of genetic research and medical therapies. In principle, biotechnological mass production of ssDNA can be achieved using Escherichia coli in a high‐cell density fed‐batch process by secreting phagemid particles derived from the filamentous M13 bacteriophages ...

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

Pest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

A Novel Antioxidant Peptide Cath‐Np Derived from Nanorana parkeri Attenuates UVB‐Induced Skin Photodamage in Mice

Integrative Zoology, EarlyView.
Schematic representation of Cath‐Np as an antioxidant suppressing acute skin damage caused by ultraviolet B (UVB) radiation in mice. Cath‐Np inhibits the activation of p53 and mitogen‐activated protein kinase pathways while it activates the Nrf2 pathway by its strong antioxidant effects, and accordingly suppresses the expression of inflammatory factors

Co‐Culture of Mammalian Cells and Photosynthetic Microorganisms for Oxygen Supply in Engineered Tissues

Cell Proliferation, EarlyView.
Continuous 28‐day light exposure alters behaviours of articular cartilage progenitor cells (ACPCs) and mesenchymal stromal cells (MSCs). Co‐culture with Leptolyngbya and Synechococcus does not adversely affect the chondrogenic capacity of ACPCs over a 28‐day period, in contrast to co‐culture with Chlorella.

KU80 suppresses endonuclease G activity to preserve genomic integrity

The FEBS Journal, EarlyView.
Under normal conditions, EndoG remains restricted to mitochondria and the genome remains intact. When KU80 is absent, EndoG translocates into the nucleus, where it promotes DNA fragmentation and genomic instability. Thus, this work highlights the importance of KU80 in tightly controlling EndoG localization to preserve genome stability.

Analysis of topological organization of chromatin during spermatogenesis in mouse testis

Genetics and Molecular Biology, 2004
Eukaryotic chromatin is organized as radial DNA loops with periodical attachments to an underlying nucleoskeleton known as nuclear matrix. This higher order chromatin organization is revealed upon high salt extraction of cells.
