GDSC1000 cell lines

Cell line propagation and verification

The GDSC1000 collection comprises well over 1,000 human tumour cell lines. This panel represents the spectrum of common and rare types of adult and childhood cancers of epithelial, mesenchymal and haematopoietic origin. Cell lines have been categorised based on therapeutically relevant tissue descriptions (GDSC descriptions 1 and 2), as well as using the TCGA tumour type descriptions. All cell lines and associated meta-data are identified and linked by a unique COSMIC ID.

Cell lines were sourced from commercial vendors and occasionally academic collaborators. Cells were grown in RPMI or DMEM/F12 medium supplemented with 5% or 10% FBS and penicillin/streptomycin, and maintained at 37°C in a humidified atmosphere at 5% CO2. Cell lines were propagated in these two media in order to minimize the potential effect of varying the media on sensitivity to therapeutic compounds in our assay, and to facilitate high-throughput screening.

To exclude cross-contaminated or synonymous lines, a panel of 92 SNPs was profiled for each cell line (Sequenom, San Diego, CA) and a pair-wise comparison score calculated for in-house identity checking. In addition, we have confirmed the identity of our cancer cell line set against those provided by the repositories, where possible. Each of the cell lines within our core set has been tested using a panel of 16 STRs (AmpFLSTR Identifiler KIT, ABI), which includes the 9 currently used by most of the cell line repositories (ATCC, Riken, JCRB and DSMZ). STR or SNP datasets for each cell line can be accessed through the cancer cell line pages of the COSMIC database (http://cancer.sanger.ac.uk/cell_lines#).

A complete list of cell lines and associated data are available from the downloads page.

Screening

Curve fitting

Fluorescence intensity data from screening plates for each dose response curve is fitted using a multi-level fixed effect model (PubMed ID: 27180993). The viability of the concentration dilution series is assumed to be sigmoidal, the classical dose-response S-shape. This function is fitted to all of the cell line - compound combinations screened. In the multilevel mixed effect model used here, two parameters are used to describe the sigmoidal curve. However, instead of fitting each dose-response series in isolation, the complete set with all combinations of cell lines - compounds screened, is fitted simultaneously. The shape parameter varies only across cell lines, while the position parameter varies across cell lines and compounds. This is a faithful and efficient representation of the data, but most importantly, it allows for borrowing strength by using all observations, which in turn allows for more accurate IC50 estimates.

Screening drugs

Compounds were screened either at the Wellcome Trust Sanger Institute or at Massachusetts General Hospital Cancer Center using a matched set of cancer cell lines. Compounds were provided by industry, academic collaborators or were sourced from commercial vendors. Where possible we have provided a full description for each compound including its name, alternative names of synonyms, screening concentration as well as reported therapeutically relevant nominal molecular target(s) and pathways/processes. Compounds were either stored in aliquots at -80°C and were subjected to a maximum of 5 freeze-thaw cycles, or stored in Storage Pods (Roylan Developments) providing a moisture-free, low oxygen environment, and protection from UV damage. The range of concentrations selected for each compound was based on in vitro data of concentrations inhibiting relevant kinase activity and cell viability, as well as clinical data indicating peak and trough plasma concentrations in human subjects.

Cell viability assays

Cells were seeded in 96-well, 384-well or 1536-well microplates at ~15% confluency in medium with 5% or 10% FBS and penicillin/streptomycin. The optimal cell number for each cell line was determined to ensure that each was in growth phase at the end of the assay and to maximise the dynamic range of the assay. One day following plating, cells were treated with range of concentrations of each compound and then returned to the incubator for assay at a 72-hour time point. Screening formats have evolved over the course of the project and include:

  • 9-point dose curve incorporating a 2-fold dilution step (256-fold range)
  • 5-point dose curve incorporating a 4-fold dilution step (256-fold range)
  • 7-point dose curve incorporating a half-log dilution step (1000-fold range)

Cell viability was determined using either a DNA dye (Syto60) or metabolic assay (Resazurin or CellTitre-Glo). All screening plates were subjected to stringent quality control measures.

Statistical analysis

To identify genomic features associated with drug response an analysis of variance (ANOVA) is used to correlate drug response (IC50 values) with genomic alterations in cancer cells including point mutations, recurrently copy number altered chromosomal segments and selected cancer gene re-arrangements (see below for details).

A pan-cancer analysis was performed using all cell lines for which drug response data were available as well as a cancer-specific analyses for each specific cancer type where sufficient data are available.

Below are some guidelines that may be useful when interpreting the data from these analyses:

  • When evaluating gene-drug associations it is important to consider both the statistical significance of the interactions as well as the effect size (i.e. difference in sensitivity between cell lines with or without a genetic feature). Associations with large-effect size and high statistical significance should be prioritised.
  • Statistical associations between drug sensitivity and cancer features can occur either in the context of a specific cancer type, and/or with a pan-cancer analysis.
  • We recommend that you use the scatter plot function to investigate the drug sensitivity data underlying each statistical association. Responses driven by outlier data points should be interpreted cautiously.
  • Our drug screens are for the testing and generation of new hypothesis. Additional validation steps are essential to demonstrate the clinical significance of our findings.
  • Our analysis is constrained by the set of cell lines and compounds screened, the set of cancer genetic features utilised for our statistical analysis, as well as the inherent limitation associated with the use of in vitro cancer cell lines for modelling drug response.

Oncogenic aberrations

To guide our statistical analyses we have built a comprehensive map of the oncogenic aberrations in >11,000 human tumors using publically available data from TCGA, ICGC and other studies. This map includes: 1) genes whose mutation patterns in whole exome sequencing (WES) data are consistent with positive selection; and 2) focal recurrently aberrant copy number segments from SNP6 array profiles (RACSs). We identified cancer functional events by combining data across all tumors (pan-cancer) as well as for each cancer type (cancer-specific).

Driver mutations in cancer genes were detected by combining the outputs of three algorithms: MutSigCV, OncodriveFM and OncodriveCLUST (Gonzalez-Perez and Lopez-Bigas, 2012; Lawrence et al., 2013; Rubio-Perez et al., 2015; Tamborero et al., 2013a). Furthermore, we mined the COSMIC database to identify recurrent, and therefore likely oncogenic, gain- or loss-of-function variants within these cancer genes. The detection of RACSs was performed using the ADMIRE algorithm (Chapman et al., 2011; Mok et al., 2009; Shaw et al., 2013; van Dyk et al., 2013). RACs were filtered to require segments to include at least one protein coding or antisense gene, but no more than 100.

The set of clinically relevant features identified from patient tumours was utilised for subsequent downstream ANOVA analysis to identify cancer features associated with drug response in cancer cell lines.

ANOVA model

We perform an analysis of variance (ANOVA) to associated drug sensitivity with individual genomic features. A drug–response vector consisting of n IC50 values from treatment of n cell lines was constructed for each drug. The model was linear (no interaction terms) with dependant variables represented by the described vector and factors including tissue type (for the pan-cancer analysis only), micro-satellite instability status (for the cancer types with positive samples for this feature) and the status of a cancer features. For the pan-cancer analysis, the union of all the cancer-specific features was used. Only cancer features occurring in at least 3 cell lines were considered and features with identical pattern of positive occurrence were merged together, thus resulting into a final set of 667 (individual or combined) features across 988 cell lines (screened against at least 1 drug). In order to include as many cell lines as possible in the pan-cancer analysis (even those not matching a TGCA type), values of the tissue factor were determined by looking at the GDSCdescription_1 label. Whereas for the cancer-specific analysis, only cell lines with a matching TCGA label were used. The tissue factors corresponding to ‘digestive_system’ and ‘urogenital_system’ were further sub-classified by using the more specific GDSCdescription_2 label. For all the tested gene-drug associations, effect size estimations vs. pooled standard deviation (quantified through the Cohen’s d), effect sizes vs. individual standard deviations (quantified through two different Glass deltas, for the feature positive and the feature negative population respectively), p-values and all the other statistical scores were obtained from the fitted models. A Benjamini–Hochberg multiple testing correction was finally applied to the resulting p-values (correcting together all those obtained in the pan-cancer analysis and on a cancer type basis those obtained in a given cancer-specific analysis). A p-value threshold of 10-3 and a false discovery rate threshold equal to 25% were finally used to call significant associations across all the performed analyses.

STR profiles of cell lines

Cell line authentication

Concerns around the identity of cancer cell lines used in scientific research have been increasing over several years and was the topic of a recent editorial in Nature (-, 2009). Cross-contamination has even been shown to be present in such widely used and supposedly well characterised groups of cell lines as the NCI60 set. For instance the NCI60 cell lines OVCAR-8 and NCI-ADR-RES have been shown to be over 97% identical using the Affymetrix SNP6.0 array in this laboratory - this result has been confirmed by multiple laboratories around the world and was recently reported in the scientific literature (Liscovitch and Ravid, 2007). Two other such pairing are also present within the NCI60 series of lines - both M14/MDA-MB-435 (Rae et al, 2007) and U251MG/SNB-19 have identities over 94% when compared using the SNP6 array.

Many of the cell line repositories are now providing short tandem repeat (STR) profiles of the lines they hold allowing identity of lines within the scientific community to be confirmed by a simple assay. We are currently confirming the identity of our cancer cell line set against those provided by the repositories, where possible. Each of the cell lines within our core set is being tested using a panel of 16 STRs (AmpFLSTR Identifiler KIT, ABI), which includes the 9 currently used by most of the cell line repositories (ATCC, Riken, JCRB and DSMZ). We are also providing a single nucleotide polymorphism (SNP) profile based on a panel of 63 SNPs assayed using the Sequenom Genetic Analyser which we use for in-house identity checking whenever a cell line is propagated.

The provision of STR profiles by the cell line repositories and of our in-house cell lines is ongoing and will be updated when appropriate.

  • MDA-MB-435 cells are derived from M14 melanoma cells--a loss for breast cancer, but a boon for melanoma research.

    Rae JM, Creighton CJ, Meck JM, Haddad BR and Johnson MD

    Background: The tissue of origin of the cell line MDA-MB-435 has been a matter of debate since analysis of DNA microarray data led Ross et al. (2000, Nat Genet 24(3):227-235) to suggest they might be of melanocyte origin due to their similarity to melanoma cell lines. We have previously shown that MDA-MB-435 cells maintained in multiple laboratories are of common origin to those used by Ross et al. and concluded that MDA-MB-435 cells are not a representative model for breast cancer. We could not determine, however, whether the melanoma-like properties of the MDA-MB-435 cell line are the result of misclassification or due to transdifferention to a melanoma-like phenotype.

    Methods: We used karyotype, comparative genomic hybridization (CGH), and microsatalite polymorphism analyses, combined with bioinformatics analysis of gene expression and single nucleotide polymorphism (SNP) data, to test the hypothesis that the MDA-MB-435 cell line is derived from the melanoma cell line M14.

    Results: We show that the MDA-MB-435 and M14 cell lines are essentially identical with respect to cytogenetic characteristics as well as gene expression patterns and that the minor differences found can be explained by phenotypic and genotypic clonal drift.

    Conclusions: All currently available stocks of MDA-MB-435 cells are derived from the M14 melanoma cell line and can no longer be considered a model of breast cancer. These cells are still a valuable system for the study of cancer metastasis and the extensive literature using these cells since 1982 represent a valuable new resource for the melanoma research community.

    Multidrug-resistant MCF-7 breast adenocarcinoma cells (originally named MCF-7/AdrR cells and later re-designated NCI/ADR-RES) have served as an important and widely used research tool during the last two decades. However, the real identity of these cells has been in doubt since 1998 and has since been debated. The origin of NCI/ADR-RES cells has now been revealed by SNP and karyotypic analyses, carried out at the Sanger Institute and the NCI, respectively. The results of these analyses, recently posted on the Web, show that NCI/ADR-RES cells are derived from OVCAR-8 ovarian adenocarcinoma cells. The case of NCI/ADR-RES cells highlights a wide-spread problem of cell line cross-contamination and misidentification. Fortunately, this is a tractable problem that can be avoided by scrupulous genotyping of cell stocks and adoption of a few simple rules in cell culture practice.

Description of data presented on the volcano plot

A volcano plot is used to visualise the correlation of drug sensitivity data with genetic events calculated using an ANOVA.

We use two different types of volcano plots to represent our data. Gene specific volcano plots represent the effect of a mutated gene (e.g. BRAF) on the responses to all drugs analysed. A drug-specific volcano plot represents how genomic changes influence response to a specific drug (e.g. BRAF inhibitor PLX4720).

In each volcano plot three pieces of data are represented:

x-axis:
The magnitude of the effect that each genetic events has on cell lines IC50 values in response to a drug. The effect size is proportional to the difference in mean IC50 between wild-type and mutant cell lines. Numbers less than 0 indicate drug sensitivity, numbers greater than 0 indicate drug resistance.
y-axis:
The p-value from the ANOVA of a drug-gene interaction on an inverted log10 scale. For clarity the axis is capped at p = 1 x 10-8 and a plus sign (+) next to a circle indicates that the p-value is smaller than this threshold.
Size of each circle:
The number of cell lines contributing to the analysis for a given genetic feature or drug.
Color
Cancer features associated with statistically significant sensitizing or resistance effects (20% FDR) are coloured green and red, respectively. By hovering over each circle the following information is provided: genetic feature, sample size (number of cell lines with feature screened), effect size and p-value. Non-signficant associations are grey.

    The use of large-scale genomic and drug response screening of cancer cell lines depends crucially on the reproducibility of results. Here we consider two previously published screens, plus a later critique of these studies. Using independent data, we show that consistency is achievable, and provide a systematic description of the best laboratory and analysis practices for future studies.

    Unlabelled: Identifying genetic alterations that prime a cancer cell to respond to a particular therapeutic agent can facilitate the development of precision cancer medicines. Cancer cell-line (CCL) profiling of small-molecule sensitivity has emerged as an unbiased method to assess the relationships between genetic or cellular features of CCLs and small-molecule response. Here, we developed annotated cluster multidimensional enrichment analysis to explore the associations between groups of small molecules and groups of CCLs in a new, quantitative sensitivity dataset. This analysis reveals insights into small-molecule mechanisms of action, and genomic features that associate with CCL response to small-molecule treatment. We are able to recapitulate known relationships between FDA-approved therapies and cancer dependencies and to uncover new relationships, including for KRAS-mutant cancers and neuroblastoma. To enable the cancer community to explore these data, and to generate novel hypotheses, we created an updated version of the Cancer Therapeutic Response Portal (CTRP v2).

    Significance: We present the largest CCL sensitivity dataset yet available, and an analysis method integrating information from multiple CCLs and multiple small molecules to identify CCL response predictors robustly. We updated the CTRP to enable the cancer research community to leverage these data and analyses.

    The high rate of clinical response to protein-kinase-targeting drugs matched to cancer patients with specific genomic alterations has prompted efforts to use cancer cell line (CCL) profiling to identify additional biomarkers of small-molecule sensitivities. We have quantitatively measured the sensitivity of 242 genomically characterized CCLs to an Informer Set of 354 small molecules that target many nodes in cell circuitry, uncovering protein dependencies that: (1) associate with specific cancer-genomic alterations and (2) can be targeted by small molecules. We have created the Cancer Therapeutics Response Portal (http://www.broadinstitute.org/ctrp) to enable users to correlate genetic features to sensitivity in individual lineages and control for confounding factors of CCL profiling. We report a candidate dependency, associating activating mutations in the oncogene β-catenin with sensitivity to the Bcl-2 family antagonist, navitoclax. The resource can be used to develop novel therapeutic hypotheses and to accelerate discovery of drugs matched to patients by their cancer genotype and lineage.

    Alterations in cancer genomes strongly influence clinical responses to treatment and in many instances are potent biomarkers for response to drugs. The Genomics of Drug Sensitivity in Cancer (GDSC) database (www.cancerRxgene.org) is the largest public resource for information on drug sensitivity in cancer cells and molecular markers of drug response. Data are freely available without restriction. GDSC currently contains drug sensitivity data for almost 75 000 experiments, describing response to 138 anticancer drugs across almost 700 cancer cell lines. To identify molecular markers of drug response, cell line drug sensitivity data are integrated with large genomic datasets obtained from the Catalogue of Somatic Mutations in Cancer database, including information on somatic mutations in cancer genes, gene amplification and deletion, tissue type and transcriptional data. Analysis of GDSC data is through a web portal focused on identifying molecular biomarkers of drug sensitivity based on queries of specific anticancer drugs or cancer genes. Graphical representations of the data are used throughout with links to related resources and all datasets are fully downloadable. GDSC provides a unique resource incorporating large drug sensitivity and genomic datasets to facilitate the discovery of new therapeutic biomarkers for cancer therapies.

    Clinical responses to anticancer therapies are often restricted to a subset of patients. In some cases, mutated cancer genes are potent biomarkers for responses to targeted agents. Here, to uncover new biomarkers of sensitivity and resistance to cancer therapeutics, we screened a panel of several hundred cancer cell lines--which represent much of the tissue-type and genetic diversity of human cancers--with 130 drugs under clinical and preclinical investigation. In aggregate, we found that mutated cancer genes were associated with cellular response to most currently available cancer drugs. Classic oncogene addiction paradigms were modified by additional tissue-specific or expression biomarkers, and some frequently mutated genes were associated with sensitivity to a broad range of therapeutic agents. Unexpected relationships were revealed, including the marked sensitivity of Ewing's sarcoma cells harbouring the EWS (also known as EWSR1)-FLI1 gene translocation to poly(ADP-ribose) polymerase (PARP) inhibitors. By linking drug activity to the functional complexity of cancer genomes, systematic pharmacogenomic profiling in cancer cell lines provides a powerful biomarker discovery platform to guide rational cancer therapeutic strategies.

    The systematic translation of cancer genomic data into knowledge of tumour biology and therapeutic possibilities remains challenging. Such efforts should be greatly aided by robust preclinical model systems that reflect the genomic diversity of human cancers and for which detailed genetic and pharmacological annotation is available. Here we describe the Cancer Cell Line Encyclopedia (CCLE): a compilation of gene expression, chromosomal copy number and massively parallel sequencing data from 947 human cancer cell lines. When coupled with pharmacological profiles for 24 anticancer drugs across 479 of the cell lines, this collection allowed identification of genetic, lineage, and gene-expression-based predictors of drug sensitivity. In addition to known predictors, we found that plasma cell lineage correlated with sensitivity to IGF1 receptor inhibitors; AHR expression was associated with MEK inhibitor efficacy in NRAS-mutant lines; and SLFN11 expression predicted sensitivity to topoisomerase inhibitors. Together, our results indicate that large, annotated cell-line collections may help to enable preclinical stratification schemata for anticancer agents. The generation of genetic predictions of drug response in the preclinical setting and their incorporation into cancer clinical trial design could speed the emergence of 'personalized' therapeutic regimens.

    Efforts to discover new cancer drugs and predict their clinical activity are limited by the fact that laboratory models to test drug efficacy do not faithfully recapitulate this complex disease. One important model system for evaluating candidate anticancer agents is human tumour-derived cell lines. Although cultured cancer cells can exhibit distinct properties compared with their naturally growing counterparts, recent technologies that facilitate the parallel analysis of large panels of such lines, together with genomic technologies that define their genetic constitution, have revitalized efforts to use cancer cell lines to assess the clinical utility of new investigational cancer drugs and to discover predictive biomarkers.

  • High-throughput lung cancer cell line screening for genotype-correlated sensitivity to an EGFR kinase inhibitor.

    McDermott U, Sharma SV and Settleman J

    Center for Molecular Therapeutics, Massachusetts General Hospital Cancer Center and Harvard Medical School, Charlestown, Massachusetts, USA.

    Human cancer cell lines that can be propagated and manipulated in culture have proven to be excellent models for studying many aspects of gene function in cancer. In addition, they can provide a powerful system for assessing the molecular determinants of sensitivity to anticancer drugs. They have also been used in recent studies to identify genomic alterations and gene expression patterns that provide important insights into the genetic features that distinguish the properties of tumor cells associated with similar histologies. We have established a large repository of human tumor cell lines (>1000) corresponding to a wide variety of tumor types, and we have developed a methodology for profiling the collection for sensitivity to putative anticancer compounds. The rationale for examining tumor cell lines on this relatively large scale reflects accumulating evidence indicating that there is substantial genetic heterogeneity among human tumor cells-even those derived from tumors of similar histologies. Thus, to develop an accurate picture of the molecular determinants of tumorigenesis and response to therapy, it is essential to study the nature of such heterogeneity in a relatively large sample set. Here, we describe the methodologies used to conduct such screens and we describe a "proof-of-concept" screen using the EGFR kinase inhibitor, erlotinib (Tarceva), with a panel of lung cancer lines to demonstrate a correlation between EGFR mutations and drug sensitivity.

    Kinase inhibitors constitute an important new class of cancer drugs, whose selective efficacy is largely determined by underlying tumor cell genetics. We established a high-throughput platform to profile 500 cell lines derived from diverse epithelial cancers for sensitivity to 14 kinase inhibitors. Most inhibitors were ineffective against unselected cell lines but exhibited dramatic cell killing of small nonoverlapping subsets. Cells with exquisite sensitivity to EGFR, HER2, MET, or BRAF kinase inhibitors were marked by activating mutations or amplification of the drug target. Although most cell lines recapitulated known tumor-associated genotypes, the screen revealed low-frequency drug-sensitizing genotypes in tumor types not previously associated with drug susceptibility. Furthermore, comparing drugs thought to target the same kinase revealed striking differences, predictive of clinical efficacy. Genetically defined cancer subsets, irrespective of tissue type, predict response to kinase inhibitors, and provide an important preclinical model to guide early clinical applications of novel targeted inhibitors.
