Three-way combinatorial CRISPR screen for analyzing interactions among druggable targets

ABSTRACT: We present a CRISPR-based multi-gene knockout screening system and new toolkits for extensible assembly of barcoded high-order combinatorial guide RNA libraries en masse. We apply this system for systematically identifying not only pairwise but also three-way synergistic therapeutic target combinations, and successfully validated double and triple combination regimens for suppression on cancer cell growth and protection against Parkinson’s disease-associated toxicity. This system overcomes the practical challenges to experiment on a large number of high-order genetic and drug combinations, and is applicable for uncovering the rare synergistic interactions between druggable targets.

Synergistic function screening of multiple checkpoint perturbation in TIL

Project description:A synergistic function screening system was established, in which a multiplexed CRIPSR knockout library targeting different checkpoint combinations was constructed and transduced into CD8+T cells to block multiple checkpoints in single cell. Based on this system, we performed a in vivo synergistic function screening of several checkpoints in tumor infiltrating CD8+T cells and find the best combined checkpoint blockade strategy to boost the CD8+T cell-mediated tumor elimination in vivo.

Capturing pairwise and multi-way chromosomal conformations using C-walks

Project description:Chromosomes are folded into highly compacted structures to accommodate physical constraints within nuclei and to regulate access to genomic information. Recently, global mapping of pairwise contacts showed that loops anchoring topological domains (TADs), are highly conserved between cell types and species. Whether pairwise loops synergize to form higher order structures is still unclear. Here we develop a conformation capture approach to study higher order organization using chromosomal walks (C-walks) that link multiple genomic loci together into proximity chains. The data captured a hierarchical chromosomal structure at varying scales. Inter-chromosomal contacts constitute only 7-10% of the pairs and are restricted by the TAD structure of the interfacing chromosomes. About half of the C-walks stay within one chromosome, and almost half of these are restricted to intra-TAD spaces. Analysis of nested topological motifs suggests hierarchical chromosomal structure is present also within TADs. Targeted analysis of thousands of 3-walks anchored at strongly expressed genes support nested, rather than hub-like, chromosomal topology at active loci. Polycomb-repressed HOX domains are shown by the same approach to form synergistic hubs. Together, the data suggest that chromosomal territories, TADs, and intra-TAD loops are primarily driven by nested, possibly dynamic, pairwise contacts.

Systematic perturbation of retroviral LTRs reveals widespread long-range effects on human gene regulation [RNA-seq]

Project description:Recent work suggests extensive adaptation of transposable elements (TEs) for host gene regulation. However, high numbers of integrations typical of TEs, coupled with sequence divergence within families, have made systematic interrogation of the regulatory contributions of TEs challenging. Here, we employ CARGO, our recent method for CRISPR gRNA multiplexing, to facilitate targeting of LTR5HS, a higher primate-specific class of HERVK (HML-2) LTRs that is active during early development and present in ~700 copies throughout the human genome. We combine CARGO with CRISPR activation or interference to, respectively, induce or silence LTR5HS en masse, and demonstrate that this system robustly targets the vast majority of LTR5HS insertions. Remarkably, activation/silencing of LTR5HS is associated with reciprocal up- and down-regulation of hundreds of human genes. These effects require presence of retroviral sequences, but occur over long genomic distances, consistent with a pervasive function of LTR5HS elements as early embryonic enhancers in higher primates.
