 Abstract

The CRISPR-Cas9 system has increased the speed and precision of genetic editing in cells and animals. However, model generation for drug development is still expensive and time-consuming, demanding more target flexibility and faster turnaround times with high reproducibility. The generation of a tightly controlled ObLiGaRe doxycycline inducible SpCas9 (ODInCas9) transgene and its use in targeted ObLiGaRe results in functional integration into both human and mouse cells culminating in the generation of the ODInCas9 mouse. Genomic editing can be performed in cells of various tissue origins without any detectable gene editing in the absence of doxycycline. Somatic in vivo editing can model non-small cell lung cancer (NSCLC) adenocarcinomas, enabling treatment studies to validate the efficacy of candidate drugs. The ODInCas9 mouse allows robust and tunable genome editing granting flexibility, speed and uniformity at less cost, leading to high throughput and practical preclinical in vivo therapeutic testing.

Microfluidic Formulation of DNA-Loaded Multicomponent Lipid Nanoparticles for Gene Delivery

E. Quagliarini, S. Renzi, L. Digiacomo, F. Giulimondi, B. Sartori, H. Amenitsch, V. Tassinari, L. Masuelli, R. Bei, L. Cui, J. Wang, A. Amici, C. Marchini, D. Pozzi, and G. Caracciolo

With recent successes reflected in literature on mRNA delivery using LNPs, scientists from the University of Rome set out to investigate whether that success can be achieved with plasmid DNA delivery using LNPs (pDNA-LNPs). Authors Quagliarini et al. 2021 synthesized pDNA-LNPs us...

Leukocyte-specific siRNA Delivery Revealing IRF8 as a Potential Anti-inflammatory Target

N. Veiga, M. Goldsmith, Y. Diesendruck, S. Ramishetti, D. Rosenblum, E. Elinav, M.A. Behlke, I. Benhar, and D. Peer

Interferon regulatory factor 8 (IRF8) protein plays a critical role in the differentiation, polarization, and activation of mononuclear phagocytic cells. In light of previous studies, we explored the therapeutic potential of IRF8 inhibition as immunomodulatory therapy for inflamm...
