Synthetic Lethality
A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.
Publication
Neddylation as a target in PIK3CA-mutated head and neck cancer.
PIK3CA encodes the catalytic subunit of phosphoinositide 3-kinase (PI3K) enzyme and is the most commonly mutated oncogene in head and neck squamous cell carcinoma (HNSCC). This study aimed to identify potential therapeutic targets in HNSCC harboring mutant PIK3CA. We used CRISPR interference (CRISPRi)-based genome-wide screening methodology to reveal targetable genetic dependencies in PIK3CA-mutated HNSCC. Screening was conducted in an HPV-positive ... [more]
