Researchers at the ӳý of MIT and Harvard have built a robust online portal that makes data and tools on the unique vulnerabilities of cancer cells easy for scientists across the globe to access and analyze. Built and compiled by the ӳý’s , project team, the publicly available portal allows any researcher to explore and analyze data on genetic and pharmacologic dependencies and associated molecular features in cancer, which could pave the way for new precision therapies aimed at the specific vulnerabilities of cancer cells.

The new DepMap portal, available at , brings together harmonized data from many publicly available resources and currently includes the following:

  • Project Achilles, a ӳý Cancer Program–based effort aimed at systematically identifying and cataloging genetic dependencies in cancer cell lines based on CRISPR-Cas9 and RNA interference (RNAi) loss-of-function screens.
  • The ӳý-Novartis Cancer Cell Line Encyclopedia, a compilation of gene expression, chromosomal copy number, and sequencing data from 947 human cancer cell lines.
  • The at the Wellcome Sanger Institute, conducted in collaboration with scientists at the Massachusetts General Hospital, which captures the sensitivities and responses of more than 1,000 genetically characterized human cancer cell lines to a wide range of anti-cancer therapeutics.
  • The Novartis Institute for BioMedical Research’s , a large-scale project involving RNAi screens in nearly 400 cancer cell lines for genetic dependencies with therapeutic potential.

The portal’s data, results, and visualization tools enable users — in particular, those with no computational background — to explore and find genetic targets for therapeutic development, and to develop a better understanding of the vulnerabilities of cancer.

The portal also incorporates a data exploration tool giving users an easy and convenient way to visualize available data (for example, to see ). Importantly, the portal provides for nearly every gene in the genome.

The DepMap portal also allows users to:

  • Identify genetic drivers that have functional importance as potential drug targets;
  • Understand dependency profiles at genome scale across more than 500 human cell lines, with more to be added; and
  • Search for cell line models that best represent an investigator's research interests.

To accelerate cancer research further, the ӳý’s DepMap project team has committed to releasing cell line genomic information and genome-wide CRISPR-Cas9 loss-of-function screen data on a quarterly basis. They will also continue to add data and tools to the portal as they become available; tools for biomarker prediction and datasets on drug sensitivity from the ӳý Cancer Target Discovery and Development Center will be added soon.

Additional information about the DepMap project will be presented at the upcoming by Dana-Farber Cancer Institute researcher and ӳý institute member William Hahn in a talk titled, “,” on April 15, 2018, at 1:05 PM CDT. AACR attendees are invited to learn more about the ӳý and the DepMap project at booth 3327.
