WebMay 17, 2024 · Here, we develop hRad51 mutants fused to Cas9 (D10A) nickase (RDN) that mediate HDR while minimizing indels. We use RDN to install disease-associated point mutations in HEK293T cells with comparable or better efficiency than Cas9 nuclease and a 2.7-to-53-fold higher ratio of desired HDR product:undesired byproducts.

WebApr 29, 2024 · Neither CtIP Δ2 nor CtIP Δ3 managed to effectively restore HDR or MMEJ back to endogenous levels (Figure 3D and E). Conversely, there was a small but statistically significant decrease in distal-EJ after complementation with CtIP Δ1, compared to CtIP WT (Figure 3F). This decrease in distal-EJ indicates a shift in the balance between HDR and ...

WebJun 28, 2024 · CRISPR-mediated genome editing has become a powerful tool for genetic modification of biological traits. However, developing an efficient, site-specific, gene knock-in system based on homology-directed DNA repair (HDR) remains a significant challenge in plants, especially in woody species like poplar. Here, we show that simultaneous … WebIn eukaryotic cells, repair of DSBs occurs primarily by two pathways: Non-Homologous End-Joining (NHEJ) and Homology Directed Repair (HDR).
