Goals of the HMS LINCS Center
Collect rich response data:
Provide rich data sets for validation of protocols and
development of standards, algorithms and informatic systems
Integrate cell-biology and genomics:
Demonstrate that coupling (i) high-throughput biochemical and
cell-based data to (ii) expression/genomic data will uncover
novel biology involved in disease and drug response.
Create signatures and understand mechanism:
Develop pathway-aware signatures of cellular response to
(pharmacological) perturbation.
Show signatures can uncover novel pharmacological mechanism
and explain variation in response.

Approaches in the HMS LINCS Center
1. Focus on drugs and medicinal chemistry:
assemble annotated collection of kinase inhibitors (clinical
and new) and measure biochemical specificity using industry
standard kinome profiling assays.
2. Collect multi-factorial pharmaco-response signatures:
capture the complexity of response in time and space using
imaging, multiplex biochemistry and transcriptional assays.
3. Apply to cancer and other diseases: including rheumatoid
arthritis, liver disease, and mitochondrial disease.
4. Develop informatics standards (ultimately a pipeline): to
collect, analyze and disseminate diverse experimental data
5. Develop pathway-focused mathematical models: at different
levels of resolution as means to create predictive pharmacoresponse-signatures (PRSs).
LINCS@HMS
Key features of the HMS center
1. Adaptive approach:
Support diverse and changing assay and data types; adapt
ongoing data collection to previous results.
2. Integration:
–
–
–
–
–
of methods and reagents across seven laboratories
of biochemical, imaging and expression assays
of chemical and cell-level annotation
of multiple nodes in signaling network
of protein, mRNA and genome data
3. Leverage:
Leverage existing efforts in participating labs by adding LINCS
standards, informatics and assays to ongoing projects
(federally and industrially funded).

Response features and single-cell data
• Cell-cell variation:
Heterogeniety in response in addition to mean response important when cell cycle is major factor.
•Outlier populations:
Uncover responses of outlier populations including those
corresponding to undifferentiated or “tumor stem cells.”
•Assay protein localization :
Monitor changes in protein localization, such as nuclear
translocation of transcription factors upon perturbation.
•Monitor cell state changes:
Assay states and morphological transitions such as cycle
arrest, induction of apoptosis, senescence, EMT etc.

Key questions
1. How diverse is ligand response? Map to subtypes (Basal A,
Basal B, Her2+ etc)
2. Are receptor protein levels correlated to RNA levels or to
ligand response? What about a protein/gene signature?
3. Among cell lines that show similar ligand responses, how
diverse are the transcriptional responses?
4. Do Her2+ lines show similar responsiveness to diverse
ErbB ligands? Predict Trastuzumab sensitivity or resistance
mechanisms?
5. More generally – does ligand response correlate to
sensitivity or predict combination drug responses?
6. Is variation in response at single-cell level predictive or
resistance mechanisms?

Challenges facing HMS LINCS Center
• Acquisition of large-scale data sets is occurring in the
absence of a robust analytical or informatics platform
– tracking, analyzing, publishing data is tricky
• Value of analyzing immediate-early pathways
biochemically on a large scale is not yet known – how
dense does data need to be to infer pathways?
• Relative merits of single-cell and population average
data sets must be established.
• Relating transcriptional (Broad) and biochemical/celllevel data (HMS) will require new statistical
approaches and modeling tools

Conflict Statement
Peter Sorger is founder of Merrimack Pharmaceuticals;
Dean of academic affairs has determined collaborative
CSR project with Merrimack is acceptable because
there is no exchange of funds.
Peter Sorger is founder of Glencoe software, commercial
developer of OME; relationship is under active
management by Dean and Becky Ward. All software is
available in the open source.
