Finally, by applying k-means clustering the complete set of genes was organized in eight clusters each representing a specific gene expression profile, probably indicating a common regulatory transcriptional mechanism.
Each cell line displayed a separate gene cluster regardless of the drug used, while no significant clusters were obtained for each specific drug treatment (data not shown).
As we explain later in the Conclusion section, within party clusters can be investigated separately by modelling data from each specific cluster through a Gaussian distribution and then generating mixture of Gaussians taking into account the ratio of each source [47, 48].
Using k-means clustering of the reduced set of transcripts we identified six clusters each demonstrating stage-specific expression in one of the six life-cycle stages, and in these (clusters 1, 2, 5, 6, 8 and 9) we further analyzed only those transcripts with a distance of less than the median distance to the centroid.
Cluster detection output [ 12, 18] includes a European summary (from ECD), summaries for individual registries, and outputs detailing each specific cluster.
We have previously shown, through this type of cluster analysis, that binding sites can be classified based on a series of factor recruitments, enabling the highlighting of commonalities in regulatory modes for modulated genes in each specific cluster [ 28].
In each specific tissue cluster, 1kb upstream sequences from PA cluster start site were scanned for finding transcription factor (TF) binding sites common to at least 60% of input sequences by MatInspector in Genomatix Genome Analyzer.
Through the application of a panel regime-switching model designed to capture heterogeneity, our findings suggest that global banking performance can be grouped into two distinctive clusters, each with its own specific regime dynamics.
The majority of these amino acids can be subdivided into three clusters; each of them is specific to its corresponding subdomain and is located on the surface of the protein.
