Abstract 3138: CellMiner Cross-Database (CellMinerCDB) for Exploration of Patient-Derived Cancer Cell Line Pharmacogenomics

Abstract CellMiner Cross-Database (CellMinerCDB) (https://discover.nci.nih.gov/cellminercdb/) is an established interactive application providing direct access and enabling exploration of cancer cell line pharmacogenomics without extensive programming experience. Data are compiled from many sources, including the National Cancer Institute (NCI), Broad Institute DepMap, Sanger/MGH GDSC, MD Anderson Cancer Center (MDACC) MCLP, and National Center for Advancing Translational Sciences (NCATS) cell line projects. In the version 2.2 update, our collection has expanded to pharmacogenomics data for 1,916 cancer cell lines and over 25,000 drugs. Drug screening data include many additional compounds for potential drug repurposing from the Broad PRISM, NCATS, and NCI. The user interface facilitates uncovering specific samples of interest and identifying drug and cell lines across databases. We also expanded the annotations for cross-referencing other databases and downloading our data for further cancer biology and drug discovery studies. Herein, we provide use cases for CellMinerCDB including (i) data reproducibility given overlaps of cell lines, genes, and drugs across databases; (ii) candidate biomarker discovery; and (iii) cross-dataset analyses.
