One of the chief goals of pooled CRISPR/Cas9 unbiased screening in cancer research is to identify genotype-specific vulnerabilities, and AML was the first disease to be systematically analyzed with this technology.236 Using this platform, the authors found several well-known potential targets for AML therapies, including BCL2, BRD4, MEN1, and DOT1L, by studying five commonly used AML cell lines and two solid tumor cell lines as controls. The gene discussed is BRD4; the disease is cancer.
