Systematic identification of G-quadruplex sensitive lethality by genome-wide genetic screening
Ontology highlight
ABSTRACT: A375 and HT1080 cells are treated with G-quadruplex ligands PDS or PhenDC3 following genome-wide shRNA knockdown. This enables the identification of genes that when silenced, specifically compromises cell growth in the presence of the ligand. First, a pilot screen was performed to determine a ligand concentration and experimental duration that caused ligand-specific, significant changes in shRNA levels. Second, a genome-wide screen was performed to globally evaluate G4-ligand synthetic lethal interactions. Third, to corroborate the G4-sensitisers uncovered in the genome-wide screen, a focussed screen was performed with a custom shRNA pool.
