  16. ‘Find Similar Pathways’ Tool Significant enrichment of my genes in particular pathways? • Analysis performed on all pathways imported into GX 10 Significant pathways are added to experiment GeneSpring

  17. e-Seminars & Workshops www.genespring.com • Recorded Seminars: • Introduction to GX 10 • Analysis of miRNA & GE data • Analysis of QPCR & GE data • Alternative Splicing • Pathway Analysis GeneSpring

  18. Affymetrix Files Getting Started in GeneSpring GX 10 Advanced Workflow: (To Find Differentially Expressed Genes) GeneSpring

  19. Cardiogenomics dataset: Affymetirx data • Congestive heart failure (CHF)is a degenerative condition in which the heart no longer functions effectively as a pump. • The most common cause of CHF isdamage to the heart muscle by not enough oxygen.  This is usually due to narrowing of the coronary arteries which take blood to the heart. • Idiopathic cardiomyopathy results in weakened hearts due to an unknown cause. • Ischemic cardiomyopathy is causedby a lack of oxygen to the heart due to coronary artery disease. GeneSpring

  20. Cardiogenomics dataset: Affymetirx data • Experimental Goal: • To identify the molecular mechanisms underlying congestive heart failure, gene expression profiles were compared between male and female patients with idiopathic, ischemic or non-failing heart conditions. CEL files generated by Affymetrix GCOS GeneSpring

  21. Experimental Setup in GeneSpring Gender Interpretation Condition 1: Female (Samples 1, 2, 5, 6, 9, 10) Condition 2: Male (Samples 3, 4, 7, 8, 11, 12 ) CHF Etiology Interpretation Condition 1: Idiopathic (Samples 1, 2, 3, 4) Condition 2: Ischemic (Samples 5, 6, 7, 8)Condition 3: Non-failing (Samples 9, 10, 11, 12) Gender/CHF Etiology Interpretation Condition 1: Female/Idiopathic (Samples 1, 2) Condition 2: Male/Idiopathic (Samples 3, 4) Condition 3: Female/Ischemic (Samples 5, 6) Condition 4: Male/Ischemic (Samples 7, 8) Condition 5: Female/Non-failing (Samples 9, 10) Condition 6: Male/Non-failing (Samples 11, 12) The selected Interpretation determines how the samples are displayed in the various views and the comparisons that are made in analyses such as statistics. GeneSpring

  22. GeneSpring GX 10 Vocabulary • Project – collection of experiments • Entity– gene, probe, probeset, exon, etc. • Interpretation – samples that are grouped together based on conditions. • Technology– A file containing information on array design and biological information (annotation) for all the entities on the array • Biological Genome–a collection of all major annotations (NCBI) for any organism; essential for Generic/Custom arrays lacking annotations GeneSpring

  23. Getting Started in GeneSpring Cardiogenomics Experiment:Transcriptional profiling to learn more about molecular mechanisms underlying Congestive Heart Failure (CHF)Sample Data: Myocardial samples from patients with normal hearts and Ischemic & Idiopathic cardiomyopathies (3 Etiologies) Variables: Gender (2) and Etiology (3)Technology:Affymetrix U133Plus2 array GeneSpring

  24. Getting Started: Create New Project From Startup screen OR from File/New Project GeneSpring

  25. Getting Started with Advanced Analysis Experiment Type:Affymetrix Expression (3 Affy choices!) Workflow Type:Advanced Analysis GeneSpring

  26. Select Data for Experiment • Select ‘Choose Files’ to load data files found on your computer. Note: ‘Choose Samples’ option is used when creating experiments with samples already loaded into GX 10 GeneSpring

  27. Sample Upload GeneSpring

  28. Summarization Algorithms in GX 10 for CEL Files • Summarization of Affymetrix probesand baseline transformation of probeset values. GeneSpring

  29. Summarization algorithms in GX 10 • In addition to different calculations, the algorithms differ in the order in which Normalization and Summarization are performed. GeneSpring

  30. Preprocessing of Affymetrix Arrays • CEL files are the raw data files that contain signal values for individual probes. • CEL files are preprocessed to generate one value per probeset. • Preprocessing steps are: • 1. Background subtraction • 2. Normalization • 3. Summarization of probeset values • Different preprocessing algorithms are available. Array Hybridization& Scanning DAT File ImageAnalysis GCOSAGCC CHP CEL File + CDF File GeneSpring

  32. Advanced Workflow Experiment Setup • Experiment Grouping • Specify parameters/conditions GeneSpring

  33. Experiment Grouping • The experimental parameters are added in this window. • For each array, the particular parameter value (condition) is also specified. • Values can be added manually or loaded from a saved file (circled in Red). GeneSpring

  34. Advanced Workflow Experiment Setup Create Interpretation • In the Guided Workflow, only one interpretation is automatically provided. • Here, users can create multiple interpretations GeneSpring

  35. Grouping and Interpretation • 2 experimental variables: CHF Etiology and Gender • For this experiment, 3 interpretations could be created: • Gender • CHF Etiology (Ischemic, Idiopathic, non-failing) • CHF Etiology and Gender: This interpretation is automatically created in the Guided Workflow. Example: Gender Only GeneSpring

  47. Performing Pathway Analysis in GX 10:1. In the Annotations Menu, select ‘Update Pathway Interactions’ from Agilent Server 2. Before choosing an organism, GX 10 must first create a Pathway Database Infrastructure. May take >10 min3. Once the Infrastructure database is complete, go back to Annotations/Update Pathway Interactions and choose your preferred organism. May take >20 minutes4. From Workflows menu (in the right margin of GX 10) select ‘Pathway Analysis’ to begin building networks GeneSpring
