111. CHANGE-seq reveals genetic and epigenetic effects on CRISPR-Cas9 genome-wide activity.Publication - [In Vitro] [Biological Effects] [Human]PII: 10.1038/s41587-020-0555-7, PUBMED 32541958, PMC PMC7652380, MID NIHMS1591991, DOI 10.1038/s41587-020-0555-7 ABSTRACT: Current methods can illuminate the genome-wide activity of CRISPR-Cas9 nucleases, but are not easily scalable to the throughput needed to fully understand the principles that govern Cas9 specificity. Here we describe 'circularization for high-throughput analysis of nuclease genome-wide effects by sequencing' (CHANGE-seq), a scalable, automatable tagmentation-based method for measuring the genome-wide activity of Cas9 in vitro. We applied CHANGE-seq to 110 single guide RNA targets across 13 thera ... SCGE data tags...

143.

Current approaches mainly rely on local injection to bypass the BBB. However, such administration is highly invasive and not amenable to treating certain delicate regions of the brain. We demonstrate a safe and effective gene editing technique by using focused ultrasound (FUS) to transiently open the BBB for the transport of intravenously delivered CRISPR/Cas9 machinery to ...

174. Engineered virus-like particles for efficient inĀ vivo delivery of therapeutic proteins.Publication - [In Vivo] [Delivery Systems] [Mouse]PII: S0092-8674(21)01484-7, PUBMED 35021064, PMC PMC8809250, DOI 10.1016/j.cell.2021.12.021 ABSTRACT: Methods to deliver gene editing agents inĀ vivo as ribonucleoproteins could offer safety advantages over nucleic acid delivery approaches. We report the development and application of engineered DNA-free virus-like particles (eVLPs) that efficiently package and deliver base editor or Cas9 ribonucleoproteins. By engineering VLPs to overcome cargo packaging, release, and localization bottlenecks, we developed fourth-generation eVLPs that mediate efficient base editing in several primary mouse and h ...

Project | Evolving High Potency AAV Vectors for Neuromuscular Genome Editing | Recombinant adeno-associated viruses (AAV) have emerged as safe and effective vectors for clinical gene therapy applications including systemic treatment of neuromuscular diseases such as Spinal Muscular Atrophy (SMA), Duchenne Muscular Dystrophy (DMD), and Giant Axonal Neuropathy (GAN) amongst others. However, genome editing in neuromuscular tissue, in particular, is challenging. The current proposal is on a comprehensive and innovative approach to evolve high potency AAV variants for systemic neuromuscular genome editing. |

Experiment | AAV tropism in kidney organoids cultured under flow | Human kidney organoids generated from human ES and iPS cells are used to evaluate tropism of AAV2, AAV8, and AAV9 that express eGFP under CMV promoter. Organoids are exposed to AAVs at MOI 10^5 from differentiation day 21 to 28. Four culture conditions were tested: U-well suspension culture, static culture on gelbrin, low flow on a chip coated with gelbrin, and high flow on a chip coated with gelbrin. Immunohistochemistry was performed to visualize transduced cells with staining for podocytes (PODXL) and proximal tubules (LTL). AAV2/2 shows the highest transduction efficiency among three serotypes evaluated, and the GFP expression is highest in the static condition. | ||
Publication | Cross-species evolution of a highly potent AAV variant for therapeutic gene transfer and genome editing. | Recombinant adeno-associated viral (AAV) vectors are a promising gene delivery platform, but ongoing clinical trials continue to highlight a relatively narrow therapeutic window. Effective clinical translation is confounded, at least in part, by differences in AAV biology across animal species. Here, we tackle this challenge by sequentially evolving AAV capsid libraries in mice, pigs and macaques. We discover a highly potent, cross-species compatible variant (AAV.cc47) that shows improved attributes benchmarked against AAV serotype 9 as evidenced by robust reporter and therapeutic gene expression, Cre recombination and CRISPR genome editing in normal and diseased mouse models. Enhanced transduction efficiency of AAV.cc47 vectors is further corroborated in macaques and pigs, providing a strong rationale for potential clinical translation into human gene therapies. We envision that ccAAV vectors may not only improve predictive modeling in preclinical studies, but also clinical translatability by broadening the therapeutic window of AAV based gene therapies. | ||

Organoids are exposed to AAVs at MOI 10^5 from differentiaiton day 21 to 28. Immunohistochemistry is performed to visualize transduced cells with staining for podocytes (PODXL), proximal tubules (LTL), loops of Henle and distal nephrons (CDH1), interstitial stromal cells (PDGFRb), and endothelia (CD31). AAV2/2 shows the highest transduction efficiency among three serotypes evaluated, and the GFP expression is highest in proximal tubular cells. | ||

Experiment | AAV2/2 transduction efficiencies in kidney organoids cultured under flow determined by FACS | Human kidney orgnaoids generated from human ES and iPS cells are used to evaluate tropism of AAV2 that expresses eGFP under CMV promoter. Organoids are exposed to AAVs at MOI 10^5 from differentiation day 22 to 23. Four culture conditions are tested: full flow on a chip, pulsed flow on a chip, no flow on a chip, U-well suspension culture. Flow cytometry is performed to quantify the transduction efficiency in LTL+ proximal tubules. U-well culture shows the highest transduction efficiency among those four conditions. | ||

Publication | CHANGE-seq reveals genetic and epigenetic effects on CRISPR-Cas9 genome-wide activity. | Current methods can illuminate the genome-wide activity of CRISPR-Cas9 nucleases, but are not easily scalable to the throughput needed to fully understand the principles that govern Cas9 specificity. Here we describe 'circularization for high-throughput analysis of nuclease genome-wide effects by sequencing' (CHANGE-seq), a scalable, automatable tagmentation-based method for measuring the genome-wide activity of Cas9 in vitro. We applied CHANGE-seq to 110 single guide RNA targets across 13 therapeutically relevant loci in human primary T cells and identified 201,934 off-target sites, enabling the training of a machine learning model to predict off-target activity. Comparing matched genome-wide off-target, chromatin modification and accessibility, and transcriptional data, we found that cellular off-target activity was two to four times more likely to occur near active promoters, enhancers and transcribed regions. Finally, CHANGE-seq analysis of six targets across eight individual genomes revealed that human single-nucleotide variation had significant effects on activity at ~15.2% of off-target sites analyzed. CHANGE-seq is a simplified, sensitive and scalable approach to understanding the specificity of genome editors. | ||

Publication | Focused ultrasound-mediated brain genome editing. | Gene editing in the brain has been challenging because of the restricted transport imposed by the blood-brain barrier (BBB). Current approaches mainly rely on local injection to bypass the BBB. However, such administration is highly invasive and not amenable to treating certain delicate regions of the brain. We demonstrate a safe and effective gene editing technique by using focused ultrasound (FUS) to transiently open the BBB for the transport of intravenously delivered CRISPR/Cas9 machinery to the brain. | ||

Publication | Engineered virus-like particles for efficient inĀ vivo delivery of therapeutic proteins. | Methods to deliver gene editing agents inĀ vivo as ribonucleoproteins could offer safety advantages over nucleic acid delivery approaches. We report the development and application of engineered DNA-free virus-like particles (eVLPs) that efficiently package and deliver base editor or Cas9 ribonucleoproteins. By engineering VLPs to overcome cargo packaging, release, and localization bottlenecks, we developed fourth-generation eVLPs that mediate efficient base editing in several primary mouse and human cell types. Using different glycoproteins in eVLPs alters their cellular tropism. Single injections of eVLPs into mice support therapeutic levels of base editing in multiple tissues, reducing serum Pcsk9 levels 78% following 63% liver editing, and partially restoring visual function in a mouse model of genetic blindness. InĀ vitro and inĀ vivo off-target editing from eVLPs was virtually undetected, an improvement over AAV or plasmid delivery. These results establish eVLPs as promising vehicles for therapeutic macromolecule delivery that combine key advantages of both viral and nonviral delivery. | ||
