Adaptive resistance of melanoma cells to RAF inhibition via reversible induction of a slowly dividing de-differentiated state

Fallahi-Sichani et al (2017) Molecular Systems Biology
Single-cell imaging, transcriptional profiling, and biochemical profiling of the responses of BRAFV600E melanoma cells to Vemurafenib uncovered a slowly dividing, de-differentiated cell state that is associated with drug resistance but that is inhibitable by novel drug combinations.

Everley et al (2017) J Proteome Res

Neutral Loss Is a Very Common Occurrence in Phosphotyrosine-Containing Peptides Labeled with Isobaric Tags

Everley et al (2017) Journal of Proteome Research
By characterizing trends in neutral loss and immonium ion formation during mass spectrometry analysis of phosphotyrosine-containing peptide samples, a set of features was identified that can inform improved method development and supplement site localization algorithms for the analysis of isobarically labelled peptides.

Erickson et al (2017) Mol Cell

A Strategy to Combine Sample Multiplexing with Targeted Proteomics Assays for High-Throughput Protein Signature Characterization

Erickson et al (2017) Molecular Cell
A new targeted mass spectrometry strategy called TOMAHAQ leverages advances in MS3 analysis of reporter ions to enable 10-plex sample multiplexing with accurate quantification directly from proteolyzed cell lysates.

Profiling drugs for rheumatoid arthritis that inhibit synovial fibroblast activation

Jones et al (2017) Nature Chemical Biology
In the context of rheumatoid arthritis, multiple kinase inhibitors partially block ligand-dependent synovial fibroblast activation and proinflammatory cytokine secretion into the synovial fluid, but the TAK1 inhibitor 5ZO is unique among the inhibitors tested in its ligand-independent efficacy across a panel of synovial fibroblasts isolated from RA patients.

Growth rate inhibition metrics correct for confounders in measuring sensitivity to cancer drugs

Hafner, Niepel et al (2016) Nature Methods
In contrast to conventional metrics for drug response such as IC50 or Emax, growth rate inhibition (GR) metrics are insensitive to division number and provide a more robust measure of the effects of perturbagens on dividing cells.

Highly multiplexed imaging of single cells using CycIF, a high-throughput cyclic immunofluorescence method

Lin et al (2015) Nature Communications
CycIF is a high-throughput cyclic immunofluorescence method that uses public domain chemistry and existing instruments to enable low-cost, high-dimensionality imaging assays at the single-cell level.

Fractional killing arises from cell-to-cell variability in overcoming a caspase activity threshold

Roux et al (2015) Molecular Systems Biology
Non-genetic cell-to-cell variability results in fractional killing by TRAIL and therapeutic antibody agonists, limiting their effectiveness as anti-cancer drugs. A simple model of initiator caspase dynamics reveals a threshold in caspase activity that separates dying and surviving cells.

Systematic analysis of BRAFV600E melanomas reveals a role for JNK/c-Jun pathway in adaptive resistance to drug-induced apoptosis

Fallahi-Sichani et al (2015) Molecular Systems Biology
Adaptive responses to RAF/MEK inhibitors can limit therapeutic success. We analyzed this adaptive response systematically across a panel of BRAFV600E melanoma lines and revealed a role for cell-to-cell variability induced by the JNK/c-Jun pathway and other factors in adaptive drug resistance.

Analysis of growth factor signaling in genetically diverse breast cancer lines

Niepel et al (2014) BMC Biology
Growth factor signaling is a key determinant of cellular behavior in normal and diseased tissue. Here, we generated a systematic dataset looking at the variance of signaling responses across the ICBP43 panel of breast cancer lines and identified potential molecular underpinnings of these responses.

Discovering causal pathways linking genomic events to transcriptional states using Tied Diffusion Through Interacting Events (TieDIE)

Paull et al (2013) Bioinformatics
Tied Diffusion Through Interacting Events (TieDIE) is a novel tool for discovering causal pathways linking genomic events to transcriptional states.

Profiles of Basal and Stimulated Receptor Signaling Networks Predict Drug Response in Breast Cancer Lines

Niepel et al (2013) Science Signaling
Profiling the levels and responsiveness of receptor tyrosine kinases (RTKs) to diverse growth factors and cytokines across libraries of cancer cell lines makes it possible to predict responsiveness to targeted therapeutics. Analysis of the predictors reveals key protein factors involved in drug sensitivity.

Metrics other than potency reveal systematic variation in responses to cancer drugs

Fallahi-Sichani et al (2013) Nature Chemical Biology
A multi-parametric analysis of a systematic set of dose-response measurements across >50 cell lines to 64 anticancer drugs reveals the extent of variability in maximal effect and slope. Non-canonical behavior appears to arise from cell-to-cell variability.

Tang et al (2013)

Differential Determinants of Cancer Cell Insensitivity to Antimitotic Drugs Discriminated by a One-Step Cell Imaging Assay

Tang et al (2013) Journal of Biomolecular Screening
A one-step, no-wash imaging assay that uses three dyes to stain living cells for mitotic and apoptotic state discriminates alternative mechanisms of compromised drug sensitivity.

McAllister et al (2013)

Mass Spectrometry Based Method to Increase Throughput for Kinome Analyses Using ATP Probes

McAllister et al (2013) Analytical Chemistry
Combination of ActivX ATP probe (AAP) affinity reagents with multiplexed isotopic labeling (TMT) enables systematic kinome analysis across up to six samples in a single LC-MS run.

Single-cell analysis of perturbagen-induced changes in the subcellular morphology of breast cancer cells

Mills et al (unpublished)

Browse and download this live-cell imaging dataset assessing subcellular morphology changes in 1.6 million individual cells across 6 breast cancer and non-tumorigenic cell lines treated with a panel of 105 kinase inhibitors.

Dynamics of perturbagen responses in living single cells
