Controlled Peptide Capture and Release in 3D‐Printed Multimaterial Microstructures

open access: yesAdvanced Science, EarlyView.
Two‐photon laser printing of 3D microstructures using a peptide‐containing ink is shown. The microstructures allow for controlled capture and release of target peptides through coiled‐coil interaction with the printed peptide inside the material. Based on these properties, orthogonal capture and stimuli‐mediated release possibilities inside printed ...

New strategies in Bioconjugation : chemical modification of nucleic acids and peptides [PDF]

open access: yes, 2015
One of the open challenges in chemical biology is to identify reactions that proceed with large rate constants in water at neutral pH values. Once assembled, these conjugates may be used for a broad variety of applications (e.g., therapeutics, imaging ...

TET1 Inhibition Promotes Therapeutic Sensitivity in TP53‐Mutant GBM by Influencing Genome Fragility and Altering TAMs Biology

open access: yesAdvanced Science, EarlyView.
In TP53mut GBM cells, reduced P53 function is associated with increased TET1 expression. Genetic or pharmacological inhibition of TET1 correlates with genome fragility, including DNA damage, cellular senescence, telomere shortening, and reactive oxygen species accumulation, which may contribute to increased efficacy of antitumor therapy.

Multiple nucleic acid cleavage modes in divergent type III CRISPR systems [PDF]

open access: yes, 2016
CRISPR-Cas is an RNA-guided adaptive immune system that protects bacteria and archaea from invading nucleic acids. Type III systems (Cmr, Csm) have been shown to cleave RNA targets in vitro and some are capable of transcription-dependent DNA targeting ...

Optimized Lipid Nanoparticles with Tail‐Modified Ionizable Lipids for Safer mRNA Delivery

open access: yesAdvanced Science, EarlyView.
Systematic engineering of hydrophobic tail architecture in vitamin B5‐derived ionizable lipids establishes a comprehensive structure–activity relationship framework for mRNA delivery. Combined lipidtail and formulation optimization identifies TM1‐OPT3‐C, a lipid nanoparticle platform that improves efficacy–safety balance through efficient mRNA delivery,

Probiotic‐Derived Vesicles Rectally Delivered via Thermo‐Gelling Copolymer Promote Mucosal Healing and Reduce Inflammation in Ulcerative Colitis

open access: yesAdvanced Science, EarlyView.
A thermo‐responsive rectal delivery platform integrating probiotic‐derived extracellular vesicles within a hyaluronic acid‐based copolymer enables localized and sustained therapy for ulcerative colitis. The formulation effectively suppresses inflammation, promotes macrophage polarization toward a regenerative phenotype, restores epithelial barrier ...

An Extended Dot-Bracket-Notation for Functional Nucleic Acids

open access: yes, 2008
Functional nucleic acids are an attractive substrate for molecular computing. A nucleic acid molecule is a linear chain of covalently bound building blocks assembled in arbitrary order from a set of typically four nucleotides.

Nucleic Acids for Computation

open access: yes, 2009
Nucleic acids have many features that are ideal for molecular computation. Using nucleic acids, we have constructed a full set of molecular logic gates, with modular stem-loop-controlled deoxyribozymes as switches and single-stranded oligonucleotides as ...
