Agilent GeneSpring GX V11.5 X86-32: A Powerful Bioinformatics Software for Gene Expression Analysis




Gene expression analysis is the study of how genes are transcribed to produce functional gene products, such as RNA or proteins, in different biological conditions. It can reveal insights into the molecular mechanisms of normal and abnormal cellular processes, such as development, differentiation, disease, and response to stimuli. Gene expression analysis can also help identify biomarkers, potential drug targets, and novel therapeutic strategies.

Microarray data is one of the most common types of data used for gene expression analysis. Microarrays are laboratory tools that can measure the expression of thousands of genes simultaneously by hybridizing labeled cDNA samples to DNA probes printed on a slide. Microarray data can provide a global view of the transcriptome, or the set of all RNA transcripts expressed by a group of genes.


However, microarray data analysis is not a trivial task. It requires specialized bioinformatics software that can handle large and complex datasets, perform various statistical tests and algorithms, and generate meaningful results and visualizations. One such software is Agilent GeneSpring GX, which is designed specifically for biologists who want to perform gene expression analysis using microarray data.

Example of a Gene Expression Analysis Project




To illustrate how to use Agilent GeneSpring GX V11.5 X86-32 for gene expression analysis, we will use an example project that is based on a tutorial provided by Agilent. The project involves analyzing Affymetrix microarray data from a study of HeLa cells that were treated with an unknown compound in a cancer treatment pilot study. The goal is to identify genes that are differentially expressed between treated and untreated samples, and to explore their biological functions and pathways. The steps are as follows:



  • Create a new project named "HeLa cells treatment" and select "Affymetrix" as the technology.



  • Create a new experiment named "HeLa cells treatment" and select "Affymetrix HG-U133 Plus 2" as the array type.



  • Import the data files from the samples folder of the main installation folder (C:\Program Files\Agilent\GeneSpringGX\samples). There are six files: three for treated samples (T1.CEL, T2.CEL, T3.CEL) and three for untreated samples (U1.CEL, U2.CEL, U3.CEL).



  • Set up the experiment parameters and conditions. There are two parameters: "Treatment" and "Replicate". The parameter values for "Treatment" are "Treated" and "Untreated". The parameter values for "Replicate" are "1", "2", and "3". Assign each sample to its corresponding parameter values. For example, T1.CEL belongs to "Treated" and "1".



  • Perform data preprocessing and quality control. Apply background correction using RMA method, normalization using quant Continuing the article: ile normalization method, and transformation using log2 method. Apply filtering using expression filter with minimum intensity of 20 and minimum number of present calls of 3. Apply outlier detection using robust multichip average (RMA) method and remove any outliers. Visualize the data quality using box plots, scatter plots, and MA plots.



  • Perform data analysis and visualization. Apply differential expression analysis using t-test with Benjamini-Hochberg multiple testing correction and fold change cutoff of 2. Apply clustering analysis using hierarchical clustering with Pearson correlation as the distance measure and average linkage as the linkage method. Apply principal component analysis to reduce the dimensionality of the data and identify the main sources of variation. Visualize the data using heat maps, bar charts, volcano plots, and principal component plots.



  • Perform data interpretation and reporting. Apply functional annotation using Gene Ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Apply gene set enrichment analysis using Gene Set Enrichment Analysis (GSEA) tool and Molecular Signatures Database (MSigDB) gene sets. Apply network analysis using Pathway Architect tool and Ingenuity Pathway Analysis (IPA) database. Generate reports using HTML or PDF formats.
