After Cas9-induced DNA double-strand breaks, repair outcomes were captured and quantified using high-throughput sequencing. This experiment aims to identify genetic factors influencing specific DNA repair outcome patterns such as 1-bp insertions, microhomology-mediated deletions, and large insertions.</description><repository>biostudies-arrayexpress</repository><sample_protocol>Nucleic Acid Extraction - Genomic DNA was extracted using MiniBEST Universal Genomic DNA Extraction Kit (TaKaRa).</sample_protocol><sample_protocol>Library Construction - PCR amplification were performed in 20 μL reactions containing 40 μg genomic DNA, 0.4 μM of each primer, and Q5 Hot Start HiFi PCR Master Mix (NEB). Cycling conditions were: 98 °C for 2 min; 20 cycles of 98 °C for 10 s and 65 °C for 45 s; and a final 5 min extension at 65 °C. PCR products were purified using Cycle Pure Kit (Omega) and size-selected by Gel Extraction Kit (Omega).</sample_protocol><sample_protocol>Sequencing - Purified amplicons were submitted to GENEWIZ for paired-end 150 bp (PE150) sequencing, generating 46 Gb of data per sample.</sample_protocol><sample_protocol>Sample Collection - The human GeCKOv2 lentiviral library (GENEWIZ, Suzhou), containing 122,756 sgRNAs targeting 19,050 genes (6 sgRNAs per gene), 1,864 miRNAs (4 sgRNAs per miRNA), and 1,000 NonTarget controls, was transduced into 3 × 10⁸ HEK293T cells at an MOI of 0.3. After 24 hours, cells were selected with 1 μg/mL puromycin. After selection, surviving cells were expanded for 4 days, the resulting IPGRM cell pool was subjected to secondary editing. In brief, a total of 6.3×107 IPGRM library cells were seeded into three T175 flasks 24 hours before transfection and cultured to 70-80% confluence. Each flask was co-transfected with 7.5 μg pCMV-Cas9 and 15 μg pU6-sgRNA plasmids targeting either sg3 or sg81</sample_protocol><figure_sub>Organization</figure_sub><figure_sub>MINSEQE Score</figure_sub><figure_sub>Assays and Data</figure_sub><figure_sub>MAGE-TAB Files</figure_sub><pubmed_authors>Yanbin Wan</pubmed_authors></additional><is_claimable>false</is_claimable><name>Genome-wide CRISPR knockout library screening coupled with high-throughput sequencing to analyze DNA repair outcomes</name><description>Cells were transduced with a genome-wide CRISPR knockout library to introduce gene disruptions across the genome.
