Optimized metrics for orthogonal combinatorial CRISPR screens

Plasmid design The information on each plasmid for combinatorial libraries is indicated in Supplementary Table S1. Plasmids used in this study to generate combinatorial libraries for SpCas9, enAsCas12a, CHyMErA, enAsCas12a (dual-gRNA), CHyMErA.v2, multiSPAS were deposited to Addgene (IDs: 189632, 189633, 189634, 189635, 189636, 189637, respectively). 3Cs oligonucleotide design The protocol…

DNA double-strand break-free CRISPR interference delays Huntington’s disease progression in mice

Plasmids LentiCRISPRv2 (Addgene; 52961) was purchased from Addgene (Cambridge, MA, USA). For HTT gene suppression, LentiCRISPR v2 plasmid with U6 promoter driving sgRNA expression and EF-1 alpha promoter driving the expression of Puromycin-T2A-HA-NLS-dCas9-NLS (or Puromycin-T2A-Flag-NLS-Cas9-NLS) was used. The sgRNA-Cas9 and sgRNA-dCas9 constructs were generated by cloning the CAG repeat-targeting sgRNA…

Phospholipase A2 inhibitor and LY6/PLAUR domain-containing protein PINLYP regulates type I interferon innate immunity

Significance Interferon (IFN)-mediated antiviral responses serve as the first line of the host innate immune defense against viral infection. Here we identify a previously uncharacterized protein designated phospholipase A2 inhibitor and LY6/PLAUR domain-containing protein (PINLYP), which is essential for embryonic development and plays an important role in type I IFN…

Genome-wide synthetic lethal screen unveils novel CAIX-NFS1/xCT axis as a targetable vulnerability in hypoxic solid tumors

Abstract The metabolic mechanisms involved in the survival of tumor cells within the hypoxic niche remain unclear. We carried out a synthetic lethal CRISPR screen to identify survival mechanisms governed by the tumor hypoxia–induced pH regulator carbonic anhydrase IX (CAIX). We identified a redox homeostasis network containing the iron-sulfur cluster…
