CRISPR-Cas9-mediated nuclear transport and genomic integration of nanostructured genes in human primary cells.

DNA nanostructures are a promising tool to deliver molecular payloads to cells. DNA origami structures, where long single-stranded DNA is folded into a compact nanostructure, present an attractive approach to package genes; however, effective delivery of genetic material into cell nuclei has remained a critical challenge. Here, we describe the use of DNA nanostructures encoding an intact human gene and a fluorescent protein encoding gene as compact templates for gene integration by CRISPR-mediated homology-directed repair (HDR).

Pyoverdine Inhibitors and Gallium Nitrate Synergistically Affect Pseudomonas aeruginosa.

Pseudomonas aeruginosa is a multidrug-resistant, opportunistic pathogen that frequently causes ventilator-associated pneumonia in intensive care units and chronic lung infections in cystic fibrosis patients. The rising prevalence of drug-resistant bacteria demands the exploration of new therapeutic avenues for treating P. aeruginosa infections.
