Das RNAi-Screening (High-Throughput-RNA-Interferenz) unter Verwendung eines Pools lentiviraler shRNAs kann ein Werkzeug sein, um therapeutisch relevante synthetische tödliche Ziele in Malignomen nachzuweisen. Wir bieten einen gepoolten shRNA-Screening-Ansatz zur Untersuchung der epigenetischen Effektoren bei akuter myeloischer Leukämie (AML).
