Transcription-coupled nucleotide excision repair and its regulation by the DNA damage checkpoint [PDF]

open access: yes, 2009
Elaborate DNA repair mechanisms have evolved, allowing cells to repair damages in their genomes. Nucleotide excision repair (NER) removes a variety of helix-distorting lesions, including those caused by ultraviolet (UV) irradiation.

Guanosine‐Quadruplex Hydrogels as Dynamic, Mechanically Tunable and Ion Conductive 3D Scaffolds for Cell Culture Applications

open access: yesAdvanced Functional Materials, EarlyView.
Versatile guanosine‐quadruplex (GQ) hydrogels are developed as dynamic biomatrices for cell culture. These scaffolds are fabricated under mild aqueous conditions, present improved stability, tunable mechanical properties within physiological ranges; fibrillar, porous microstructure, ion conductivity, and cytocompatibility.

Prostate Cancer Patient‐Derived Organoids (PDOs) as Functional Avatars for Antisense Oligonucleotide (ASO)‐Based Personalized Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
Prostate patient‐derived organoids (PDOs) were established from TURP and biopsy specimens with >90% success and retain key features of their tissues of origin, making them functional avatars for antisense oligonucleotide (ASO) therapy . Transfecting single cells outside the Matrigel matrix and then reconstituting organoids overcomes the 3D delivery ...

Dynamic Loading Regulates Meniscus‐Like Matrix Production in Human Mesenchymal Stromal Cell‐Seeded PET Scaffolds

open access: yesAdvanced Healthcare Materials, EarlyView.
Dynamic compression enhances mesenchymal stromal cell proliferation in nonwoven PET scaffolds under chondrogenic differentiation conditions and triggers mechanosensitive transcriptional programs associated with extracellular matrix remodeling. These findings highlight the potential of mechanically stimulated PET scaffolds as a promising platform for ...

A Hybrid Bioprinting–Microfabrication Approach to Controllable Multitype Spheroid Arrays for Modeling Tumor Heterogeneity

open access: yesAdvanced Healthcare Materials, EarlyView.
This work introduces a “cancer‐in‐a‐well” technology that recreates tumor heterogeneity in vitro using multitype spheroid arrays. Combining bioprinting/microdispensing with microstructured culture devices, the system improves drug screening and modeling of tumor complexity.

Aggregation of Single Nucleotide Polymorphisms in a Human H5N1 Clade 2.2 Hemagglutinin [PDF]

open access: yes, 2007
The evolution of H5N1 has attracted significant interest 1-4 due to linkages with avian 5,6 and human infections 7,8. The basic tenets of influenza genetics 9 attribute genetic drift to replication errors caused by a polymerase complex that lacks a ...

Systematic identification of variant-specific RNA structure-small molecule interactions exemplified by RNA G-quadruplexes

open access: yesNature Communications
Individual genetic variations, such as cancer-associated somatic mutations, alter RNA structures, thereby potentially enhancing or inhibiting the binding of RNA-targeting small molecules. However, to date, no approach has been available to identify these

Iterative Selection of DNA Nanostructures for Cellular Uptake

open access: yesAdvanced Materials, EarlyView.
DNA nanostructures are promising cell targeting delivery vehicles for therapeutics, but the targeting behavior is not fully understood. In this study, libraries of DNA nanostructures that can be amplified and sequenced are combined with cellular uptake as a selection pressure to iteratively refine DNA structures taken up in cells to better understand ...
