Topics to be Covered Introduction to CellMiner Introduction to rcellminer
What is CellMiner? Website: http://discover.nci.nih.gov/cellminer Retrieval and integration for NCI-60 datasets: molecular and pharmacological NCI-60 60 human cancer cell lines from 9 tissues of origin: breast, central nervous system, colon, leukemia, melanoma, non-small cell lung, ovarian, prostate, and renal Used by the Developmental Therapeutics Program of the National Cancer Institute to screen over 100,000 chemical compounds and natural products A subset of ~21,000 drugs is provided by CellMiner Drug activity levels expressed as 50% growth-inhibitory levels (GI50) were determined at 48 hours using the sulforhodamine B (SRB) assay Determines cell density based on the measurement of total cellular protein content
What is rcellminer? Website and Tutorial (Vignette): https://www.bioconductor.org/packages/release/bioc/html/rcellminer.html Publication: http://www.ncbi.nlm.nih.gov/pubmed/26635141 Provides programmatic access to CellMiner NCI-60 data Data Types Gene and protein expression, copy number, whole exome mutations, etc Activity data for ~21K compounds and information on their structure, mechanism of action, and repeat screens Easy visualization of compound structures, activity patterns, and molecular feature profiles Embedded R Shiny applications allow interactive data exploration
Pattern Comparison using rcellminer library(rcellminer) # Get drug and expression data drugAct <- exprs(getAct(rcellminerData::drugData)) expData <- getAllFeatureData(rcellminerData::molData)[["exp"]] # Create pattern of interest patternOfInterest <- expData["SLFN11", ] # Run pattern comparison to get correlated drugs and other gene expressions r1 <- patternComparison(patternOfInterest, drugAct) r2 <- patternComparison(patternOfInterest, expData) head(r1, 3) COR PVAL 639174 0.8343842 1.227589e-16 681636 0.7967239 1.243962e-13 34462 0.7950691 3.302182e-14 head(r2, 3) COR PVAL SLFN11 1.0000000 0.000000e+00 BCAT1 0.5847423 9.298535e-07 CCDC181 0.5766713 1.419268e-06
Embedded Shiny Applications Simplified web applications to do common data exploration tasks Compare any two molecular and drug profiles Find related structures View information on repeat screening for drug compounds
