Published: January 2017

CRISPR-based genome editing has been widely implemented in various cell types. In silico single guide RNA (sgRNA) design is a key step for successful gene editing using the CRISPR system, and continuing efforts are aimed at refining in silico sgRNA design with high on-target efficacy and reduced off-target effects. Many sgRNA design tools are available, but careful assessments of their application scenarios and performance benchmarks across different types of genome-editing data are needed. Efficient in silico models can be built that integrate current heterogeneous genome-editing data to derive unbiased sgRNA design rules and identify key features for improving sgRNA design. Comprehensive evaluation of on-target and off-target effects of sgRNA will allow more precise genome editing and gene therapies using the CRISPR system.

Background: CRISPR is widely used to silence genes by inducing mutations expected to nullify their expression. While numerous computational tools have been developed to design single-guide RNAs (sgRNAs) with high cutting efficiency and minimal off-target effects, only a few tools focus specifically on predicting gene knockouts following CRISPR. These tools consider factors like conservation, amino acid composition, and frameshift likelihood.

Artificially functional RNAs, such as fluorogenic RNA aptamer (FRApt)-based biosensing tag, represent significant advancements in various biological applications but are limited by the lack of insight into dynamic structure ensembles and universal design concepts. Through the development of an artificial RNA structure ensemble, we rationally established an RNA reconstitution model, "SSPepper-Apt," to generate a universal fluorogenic RNA biosensing tag. By utilizing various target-recognizing RNA motifs, SSPepper-Apt enables the modular generation of sensing tags for low-background, highly selective imaging of metabolites, peptides, and proteins in living cells.

KMT2A rearrangements are associated with a poor clinical outcome in infant, pediatric, and adult acute lymphoblastic and myeloid leukemia. Here, we present a protocol to reconstruct chromosomal translocations with different partner genes of KMT2A in vitro. We describe steps for patient-specific single guide RNA (sgRNA) design, optimized sgRNA in vitro transcription, detailed purification of hematopoietic stem and progenitor cells (HSPCs) from umbilical cord blood (UCB), and CRISPR-Cas9 editing of the test cell line K562 as well as UCB HSPCs.
