These off-target CRISPR events are manageable when one or two genes are targeted through downstream quality control processes, such as whole genome sequencing and other screens, to identify cells without off-target activity. However, issues arise when off-target DSBs are generated, potentially resulting in genomic changes that steer an edited cell towards immortality within the transfused patient. The formation of a DSB at the targeted gene editing site is not in itself an issue. In the context of the stability of the whole genome, this is a potentially catastrophic occurrence. The mode of action of CRISPR is to generate a DNA double-strand break (DSB) to facilitate a gene modification event. While CRISPR has been a massively disruptive technology within the gene editing field and has delivered significant scientific breakthroughs since its emergence, it might not be the most suitable gene editing technology for cell therapy. To achieve a modified cell with this phenotype, it is likely that between five and ten simultaneous gene knockouts would be required. An attractive path to overcome these issues involves gene editing the therapeutic primary cell to enable it to survive, proliferate, and successfully target the cancerous cells in the patient. The main issues include compromised survival of engineered therapeutic primary cells in the toxic tumor microenvironment, as well as poor persistence and a low proliferation rate. The potential is limitless.Delivering cell therapy to oncology patients with solid tumors has to date been unsuccessful. And of course, gene editing is likely to become a major player in the treatment of genetic diseases. To further support a sustainable future, gene editing is being used to modify crops to better withstand the changing world climate conditions and increase food production. We can now enable the use of a wider range of microbes to create industrial products that pre-CRISPR required precious natural resources. Beyond human disease applications, gene editing is being used to create greener chemistries. Precision gene editing has a long reach and will impact many facets of life. This system is based on a sequence of 30 amino acids and condenses anionic cargo, such as mRNA, irrespective of size, into nanoparticles for highly efficient entry into cells. Professor Helen McCarthy, PhD will review the key issues around RNA delivery and describe a novel peptide-based drug delivery system that her company has developed. In this final webinar of a four-part series on RNA, cohosted by The CRISPR Journal and GEN, we will delve into the delivery question surrounding mRNA research and therapeutics. Alternative mRNA delivery systems offer the capability to stealthily deliver nucleic acids to their target and evade the immune system while generating a potent antigen-specific CD8+ T-cell response. However, while LNPs have proven effective, they provide investigators with several challenges-most importantly, the activation of unwanted cell-mediated immune responses. The delivery of mRNA molecules has been dominated by the use of lipid nanoparticles (LNPs). The recent success of mRNA vaccines during the COVID pandemic has vaulted this technology from its humble research beginnings to international recognition by the scientific and medical community as a groundbreaking measure in combating a host of diseases. Webinar Stealth Mission: Novel mRNA Vaccine Delivery System Additionally, her team has developed a new sequencing-based assay for rapidly validating hits from pooled KO CRISPR screens. She will show examples of how rapid deep sequence analysis has guided experimental design, leading to high-efficiency genome editing in a broad range of applications. In this webinar hosted by The CRISPR Journal, Shondra Pruett-Miller presents a novel Python-based computer program called CRIS.py that allows the easy analysis of multiple types of editing events. However, the large amounts of data generated by targeted deep sequencing can be difficult to interpret and quickly analyze. Targeted deep sequencing enables the detection and quantification of on-target editing events in pools of cells or clonal populations. CRISPR is a powerful genome editing tool used in biomedical research for generating custom-edited cell and pre-clinical animal models. Genome engineering enables the manipulation of complex genomes down to the nucleotide level. Webinar New Tools for Analysis of CRISPR Editing Events
