g, ROC and precision/recall curves were obtained after classifying predefined essential (n = 354) and non-essential (n = 747) genes based on gene-level rank positions calculated using depletion fold changes.
Variant alleles in four genes were associated with breast cancer risk based on gene-level tests: MAP3K1, MMP9, TANK, and TLR9.
However, this will not be a major concern, since the majority protein-protein interaction data are collected based on gene-level experimentation data and therefore do not offer isoform-level resolution anyway.
Because we noted some correspondence between Paupar binding and gene expression level, we supplied GAT with a file stratifying the workspace into six bins based on gene expression level in N2A cells under the '–isochore' option to conservatively avoid associations solely due to expression level.
Genes were ranked based on gene expression level difference.
CEL files were downloaded, normalized with rma algorithm and filtered based on gene expression level (>5 in the log2 scale, at least 50% of samples) and InterQuartile Range (IQR >10% of average total IQR).
This tree showed that the genetic groups O, S1, S2, S3, and the out-group, were also separable based on gene expression level.
On the other hand, our data was based on gene expression levels as measured by RT-PCR.
Hierarchical clustering of sequenced samples based on gene expression levels was drawn using the cummeRbund package (http://rgm3.lab.nig.ac.jp/RGM/R_package_list).
Genes were analyzed based on gene expression levels and categorized into different functional groups based on the description of the Gene Ontology (GO) consortium to identify statistically significant terms.
When there are sufficient samples, similar genes can be determined based on Pearson correlation coefficient which considers the linear correlation and is computed based on gene expression levels.
