About Project Achilles

Project Achilles is part of the Cancer Dependency Map Project which aims to identify genetic and small molecule vulnerabilities and link them to biomarkers that predict their response. In Project Achilles we use lentiviral-based pooled shRNA and CRISPR/Cas9 libraries for genome-wide screening. This allows for the stable suppression of each gene individually in a subset of cells within a pooled format allowing for a cost-effective genome scale interrogation of gene essentiality. Rigorous quality controls, including multiple cell line fingerprinting steps, and monitoring of cell / reagent representation throughout the screening process are performed to ensure the quality of the data. The protocols are highly standardized to ensure that the data can be compared across cell lines.

Current datasets

Project Achilles is an ongoing effort aiming at screening >1000 cell lines of a variety of lineages, including cell lines derived from both solid and hematopoietic tumors of pediatric and adult lineages. The use of multiple cell lines is critical to model the genomic diversity of human cancer and to accommodate imperfect correlation between genotype and phenotype. We currently have data for 216 cell lines (v2.4.3) screened with an shRNA library as well as 33 cell lines screened with a CRISPR-Cas9 library (v3.3.8) (https://portals.broadinstitute.org/achilles/datasets/all). Additional data is being generated and will be released on an ongoing basis.
