Special Issue Information

Dear Colleagues,

This Special Issue explores the role of CRISPR-based genome editing approaches in cancer therapy. Genome editing using RNA-guided programmable clustered regularly interspaced short palindromic repeats (CRISPR)-associated (Cas) nucleases has revolutionized genetic research, offering unparalleled speed, efficiency, and precision. Since its first application in mammalian cells more than a decade ago, the CRISPR toolbox has rapidly expanded, continuously offering novel genetic tools aiding disease modeling and therapeutic approaches, including in cancer.

For this Special Issue, we welcome submissions that harness novel advancements of CRISPR-technology aimed at improving cancer treatments, including but not limited to CRISPR-based genome editing in cancer cells, immunotherapy approaches using CRISPR technology, CRISPR diagnostics for early cancer detection and monitoring, or the use of functional genomic screens to identify novel cancer-driving genes. Studies highlighting the role of using CRISPR-based genome editing for anti-cancer treatments are of particular interest.

By highlighting innovative research and translational applications, we endeavor to advance our understanding of how CRISPR-based genome editing approaches can shape personalized anti-cancer treatments.

Conventional methods for generating knock-out or knock-in mammalian cell models using CRISPR-Cas9 genome editing often require tedious single-cell clone selection and expansion. In this study, we develop and optimise rapid and robust strategies to engineer homozygous fluorescent reporter knock-in cell pools with precise genome editing, circumventing clonal variability inherent to traditional approaches. To reduce false-positive cells associated with random integration, we optimise the design of donor DNA by removing the start codon of the fluorescent reporter and incorporating a self-cleaving T2A peptide system. Using fluorescence-assisted cell sorting (FACS), we efficiently identify and isolate the desired homozygous fluorescent knock-in clones, establishing stable cell pools that preserve parental cell line heterogeneity and faithfully reflect endogenous transcriptional regulation of the target gene. We evaluate the knock-in efficiency and rate of undesired random integration in the electroporation method with either a dual-plasmid system (sgRNA and donor DNA in two separate vectors) or a single-plasmid system (sgRNA and donor DNA combined in one vector). We further demonstrate that coupling our single-plasmid construct with an integrase-deficient lentivirus vector (IDLV) packaging system efficiently generates fluorescent knock-in reporter cell pools, offering flexibility between electroporation and lentivirus transduction methods. Notably, compared to the electroporation methods, the IDLV system significantly minimises random integration. Moreover, the resulting reporter cell lines are compatible with most of the available genome-wide sgRNA libraries, enabling unbiased CRISPR screens to identify key transcriptional regulators of a gene of interest. Overall, our methodologies provide a powerful genetic tool for rapid and robust generation of fluorescent reporter knock-in cell pools with precise genome editing by CRISPR-Cas9 for various research purposes.
