Can I analyze single-cell data with the RNA-seq Analysis Portal?
No, the RNA-seq Data Analysis Portal cannot analyze single-cell data. However, it is designed to support relative gene expression profiling from larger samples such as bulk cells in culture and tissues.
How is RNA-seq data analyzed?
RNA sequencing data is analyzed in three steps: primary, secondary and tertiary data analysis. Primary RNA sequencing analysis converts sequencing reads into gene-specific raw expression values. Secondary RNA sequencing analysis calculates fold-change and p-value results from raw expression values. Tertiary RNA sequencing analysis interprets those results through comparisons with known pathways and diseases and by identifying upstream regulators.
How is primary RNA sequencing data analysis performed?

The general steps performed by primary RNA sequencing analysis pipelines include, but are not limited to:

  1. Demultiplexing sample indices if used to multiplex samples in the same sequencing run
  2. Correcting for amplification errors by merging sequencing reads into Unique Molecular Index (UMI) reads
  3. Trimming reads of low quality and ambiguous nucleotides as well as any adapter sequences if needed
  4. Mapping sequences to the correct species-specific transcriptome to identify the sequenced genes
  5. Counting the number of UMIs per gene to obtain their raw expression values in each sample

However, with the RNA-seq Analysis Portal and its fixed but optimized RNA sequencing analysis pipeline, you don’t have to worry about these details. The application does it all for you. As such, biological researchers like yourself can focus on the critical parameters of secondary differential gene expression analysis.

How is secondary RNA sequencing data analysis performed?

After completing primary RNA sequencing analysis to obtain raw gene expression values for each sample, secondary differential gene expression analysis then:

  1. Normalizes the raw data to control for variability in performing the experiment from RNA isolation through the sequencing runs
  2. Averages the normalized data across the same groups of replicate samples
  3. Calculates the fold change values or the ratio of the average normalized gene expression values between two experimental groups
  4. Calculates p-values to determine the statistical significance for each fold change value

As easy as these calculations are to perform, the RNA-seq Analysis Portal automatically performs all them for you, once you set up your RNA sequencing-based differential gene expression analysis by defining the samples and groups to be compared. From there, the fold-change and p-values and other intermediate values are used for RNA-seq data visualizations such as a volcano plot and a heatmap, again automatically generated by the RNA-seq Analysis Portal for you.

How is tertiary RNA sequencing data interpretation performed?

Once determined, a list of statistically significant differentially expressed genes is interpreted by comparing with known pathway and disease gene lists and by identifying upstream regulators.

The list of statistically significant differentially expressed genes are compared with genes known to be involved with specific pathways or associated with specific diseases. Such a comparison helps biological researchers like yourself gain a deeper understanding of biology behind, or driven by, the differential gene expression observed in the experiment. Pathway comparisons can also even help you gain a deeper understanding of how the differentially expressed gene are regulated.

The number of differentially expressed genes, the number of genes associated with the pathway or disease, and the number of overlapping genes all define the statistical significance and the relevance of that overlap. The result of such enrichments are then typically sorted by decreasing statistical significance to bring the most relevant ones to the top.

Collecting all the genes for all the possibly relevant pathways and diseases can be extremely time consuming, and not all of this information is publicly available. The statistical significance calculations can also be rather complicated.

However, the RNA-seq Analysis Portal automatically compares your list of differentially expressed genes with comprehensive gene lists in a knowledge base containing a comprehensive list of pathways and diseases. The RNA-seq Analysis Portal also automatically calculates the statistical significance of those overlaps and returns a list of the top ten most relevant pathways and the top ten most relevant diseases, Finally, it even reports the top ten most relevant predicted upstream regulators including miRNA.

How should I normalize my raw RNA sequencing data?

Normalization should be performed in a way that best controls for variability in the experimental protocol from the RNA isolation step through the sequencing runs.

A normalization factor or value is calculated for each sample that should be roughly uniform across the analyzed samples’ datasets. The raw expression values are then divided by the sample-specific normalization factor before continuing with averaging the normalized data and calculating fold change values and p-values.

Various normalization methods exist, and normally you would try a few and choose one that seems to work the best for your dataset. However, with the RNA-seq Analysis Portal and its published and well-established normalization method, you don’t have to worry about these details. It already uses a published and widely-accepted normalization method.

How should I set up my RNA sequencing-based differential gene expression analysis?

Any good experimental setup must include replicate treated or affected experimental samples and replicate untreated or unaffected control samples for comparison.

A critical factor is setting up any differential gene expression analysis is to define the groups for comparison. Any good experimental setup includes not only a set of treated or affected experimental samples or test samples, but also a set of untreated or unaffected control samples to which all experimental samples or test samples are compared.

Datasets obtained from samples using the same biological condition are therefore grouped and their normalized data across each individual gene averaged before calculating fold-change values during the secondary differential gene expression analysis. Experimental and/or biological replicates for every condition are also crucial for determining the statistical significance of those differential gene expression analysis results by calculating p-values.

Once these group definitions have been made in the RNA-seq Analysis Portal, the application takes care of the rest of the differential gene expression analysis for you.

What are fold change values and how are fold change values calculated?

Fold change vales are the ratios of the average normalized expression values between experimental and control groups for each gene in the dataset.

Fold change values greater than one indicate up-regulation in experimental groups relative to control groups. Fold change values less than one indicate down-regulation in experimental groups relative to control groups.

As easy as these calculations are to perform, the RNA-seq Analysis Portal automatically calculates them for you, once you set up your RNA sequencing based differential gene expression analysis by defining the samples and groups to be compared.

What are p-values and how are p-values calculated?

The p-values represent the likelihood of obtaining the observed results if no real difference existed, and various methods are available to calculate p-values.

The lower the p-value, the greater the statistical significance of the associated fold change values. The higher the p-value, the smaller the statistical significance of the associated fold change values. More extreme fold change values tend to have smaller p-values. More samples can improve p-values, especially for smaller changes in expression or smaller fold change values.

Calculating p-values is a bit complicated, and there are a number of methods to correct them for false discoveries. However, the RNA-seq Analysis Portal automatically calculates them for you and corrects for false discoveries, once you set up your RNA sequencing-based differential gene expression analysis by defining the samples and groups to be compared.

Introducing RNA Sequencing-Based Differential Gene Expression Analysis with the RNA-Seq Analysis Portal

The RNA-seq Analysis Portal is an online RNA sequencing analysis software application designed for biological researchers with little or no bioinformatics experience or expertise. Its RNA sequencing analysis pipeline is fixed but optimized so you don’t have to worry about the primary RNA sequencing analysis details. The RNA-seq Analysis Portal also completes the secondary differential gene expression analysis calculations of fold-change values and p-values. The RNA-seq Analysis Portal also provides RNA-seq data visualizations such as a volcano plot and a heatmap, both commonly used to report differential gene expression analysis results in peer-reviewed publications. All you need to focus on is setting up the sample comparisons that you need to make.

With the RNA-seq Analysis Portal, you can analyze your raw RNA next generation sequencing data for your gene expression-based biomarker discovery – or any other project – with ease and confidence. It supports seven of the most frequently used RNA library preparation kits and 18 of the most commonly studied species model systems. Move immediately from your instrument’s FASTQ files to raw gene expression values. Fixed but optimized pipelines are available specific for the RNA library preparation kit that you used. Transcriptomes for each of the supported species are also available to automatically map reads to genes.

The RNA-seq Analysis Portal automatically takes the raw gene expression values and calculates fold change values and p-values using a published and well-established normalization method to correct for any experimental variation from nucleic acid isolation through the sequencing run. You are then free to use the fold change value and p-value filters as well as the automatically updated volcano plot and heatmap visualizations to find a subset of statistically significant differentially expressed genes. The application’s “What’s Next” feature allows you take that preliminary biomarker panel and further validate it using an alternative method such as real-time or digital RT-PCR experiments and a larger number of samples.

The volcano plot automatically generated by the RNA-seq Analysis Portal graphs for each gene the log2 of its fold change value on the x-axis versus the log10 of its p-value on the y-axis. A log2 fold change value on the x-axis of zero means no change in gene expression. Up-regulated genes return positive, while down-regulated genes return negative log2 fold change values on the x-axis. Larger numbers log10 p-value y-axis values indicate greater statistical significance. The most statistically significant differentially expressed genes of interest lie in the upper left and right sections of the volcano plot beyond researcher defined thresholds.

The heatmap automatically generated by the RNA-seq Analysis Portal is a non-supervised hierarchical clustering of selected normalized gene expression values across all samples. Genes are clustered along one axis, while samples or groups are clustered along the other axis. More intense color coding indicates lower or higher normalized expression values for each gene across the samples or groups compared. Samples should cluster into their defined experimental groups. Genes that have similar patterns of gene expression changes across the samples or groups then cluster together. Results may be used to build the classifiers that determine to which groups newly analyzed samples belong based on the expression of the genes selected and defined by the preliminary experimental analysis.

Setting thresholds for fold change value and p-value filters is crucial for interpreting any differential gene expression analysis. Transcriptome analyses can return thousands of differentially expressed genes. This number of targets is too many to be analyzed conveniently by real-time or digital RT-PCR. They may also be too many to analyze affordably with a focused or targeted RNA sequencing panel. Increasing fold change value and p-value threshold stringency decreases target numbers to only the most statistically significant and differentially expressed genes and those more likely to distinguish biological phenotypes. The RNA-seq Analysis Portal allows to easily and conveniently adjust fold change and p-value thresholds and immediately see the reduced number of gene targets in its table, volcano plot, and heatmap.

By combining all these features into one application, the RNA-seq Analysis Portal allows biological researchers like yourself to focus on the final differential gene expression analysis results. Simply ensure you have included appropriate control samples and multiple replicates for each of your biological conditions, including the controls. Then, move immediately to defining the sample or group comparisons you need to make.
