Driven by the decreasing costs and increasing performance of next-generation sequencing (NGS) technologies, the amount of available genomic data has grown exponentially in recent years.  While most of the analyses of these data is done computationally, there are many instances where visual inspection of the original and/or processed data is invaluable. Such direct visualization can provide: “sanity checks” on computational results; novel biological insights; aid in communicating results; and a better understanding of the interplay between spatially related biological elements. These visualization, pathways and enrichment analysis tools are relevant whether one is interested in expression analysis (RNA-Seq), variant detection (Exome-Seq), protein binding (ChIP-Seq), or any other genome scale data.

WORKSHOP AGENDA

Day 1 – Monday, May 22, 2017

9:30 – 10:00 am                      Introduction to Workshop Concepts and Sessions
                                               Presenter: Anand S. Merchant, MD, PhD
 
10:00 am – 12:30 pm             MetaCore
                                              Presenter: Matthew Wampole, PhD
 
MetaCore™ is an integrated curated knowledge database and software suite for pathway analysis of experimental data and gene lists. The scope of data types includes microarray and sequence-based gene expression, SNPs and CGH arrays, RNAi screens, gene variants, proteomics, metabolomics, Co-IP pull-out and other custom interactions which can all by analyzed in tandem. In this session, we’ll be analyzing data published recently in PNAS about NOTCH1 signaling in chronic lymphocytic leukemia (http://www.pnas.org/content/114/14/E2911.abstract). From this publication, we’ll explore what pathways are enriched by up regulated genes by ICN1-HA from RNA-seq and bound to NOTCH1 in CHiP-seq experiments. Use overconnectivity analysis to associate transcription factors with the regulation of these upregulated genes.  Compare RNA-seq expression data chronic lymphocytic leukemia cells derived from patients with and without NOTCH1 mutations and expression. Finally, we’ll use the ICN1-HA induced up-regulated gene signature to compare against publically available GEO microarray data to find similar signatures in other diseases.
 
12:30 – 1:00 pm                    LUNCH BREAK
 
1:00 –  4:00 pm                     QluCore Omics Explorer
                                              Presenter: Carl-Johan Ivarsson, PhD
 
This session will include introduction to and exercises on basic features and functionality in Qlucore Omics Explorer. It is intended for new users and does not require that you have previous experience with Qlucore Omics Explorer. After the training you should be able to do the following using Qlucore Omics Explorer:
  • Import data and annotations
  • Present data with different plot types (PCA, heatmap, bar, box…)
  • Identify discriminating variables using basic statistical test
  • Use visualization to enhance analysis and interpret results
  • Explore large data sets – find structure, patterns and subclusters in data
  • Export variable lists and images

Day 2 – Tuesday, May 23, 2017

9:30 am – 12:30 pm             Open-Source Tools for Analysis and Visualization of NGS Data (CRAVAT, MuPIT, and NG-CHM)
                                             Presenter: Michael Ryan, PhD, Johns Hopkins/MD Anderson/ In Silico Solutions
 
Cancer-Related Analysis of VAriants Toolkit, or CRAVAT (www.cravat.us), is a free tool for high-throughput analysis of human sequencing variants developed by the Karchin lab at Johns Hopkins and In Silico Solutions.  CRAVAT accepts very large variant data files containing single nucleotide substitutions as well as indels and returns a wide variety of annotations and scores that help with identification and exploration of important variants.  The workshop will provide some background on CRAVAT and lots of hands-on exercises to learn how to use the tool and interpret the results.
 
Mutation Position Imaging Toolbox, or MuPIT (www.mupit.icm.jhu/MuPIT_Interactive/), is a sister tool to CRAVAT that shows human mutations on 3D protein structures.  MuPIT analysis enables identification of mutational clusters and proximity to functional domains in 3D space that are not obvious from the linear protein sequence. The focus of the workshop will be a series of exercises to learn how to visualize your mutations in MuPIT, how CRAVAT and MuPIT are integrated, and how to manipulate, investigate, and understand the results.
 
Next Generation Clustered Heat Maps, or NG-CHM(http://bioinformatics.mdanderson.org/chm), is a tool developed by MD Anderson and In Silico Solutions to build clustered heat maps for genomic data. It provides interactive heat maps that enable the user to zoom and pan across the heat map, alter its color scheme, generate production quality PDFs, and link out from rows, columns, and individual heat map entries to related statistics, databases and other information.

12:30 – 1:00 pm                    LUNCH BREAK
 
1:00 –  4:00 pm                     Ingenuity Pathway Analysis (IPA)
                                              Presenter: Jennifer Poitras, PhD
 
In this session, you will get an opportunity to use IPA for maximizing the biological interpretation of gene, transcript & protein expression data using different modules of the tool. There will hands-on exercises from file uploading to interpreting results, visualizing and integrating multi-omics data, understanding and mining the Ingenuity Knowledge Base (IKB), core analysis, causal networks, and many more new functionalities.
