Extensions of the Plaid Model for Two-Way Clustering of Microarray Data
... Traditional cluster analysis partitions the genes or the samples into a set of exhaustive, mutually exclusive clusters, implying that each gene or each sample responds to exactly one biological process. Art Owen and I introduced the plaid model as a form of cluster analysis in which genes and sample ...

... Supplementary Fig S7: A Schematic Figure of the Key Driver Analysis (KDA). In order to test if gene G (shown in red) is a KD or not, the subnetwork of G is first extracted by retrieving its 1st to 3rdlayer neighbor genes in the network. Subsequently, the enrichment of genes in a given BP gene set (s ...

Gene Regulation
... Some genes are regulated (turned off and on) by repressor proteins While others use proteins that enhance the rate of transcription. Operons are generally not found in Eukaryotes. Gene regulation is controlled individually and have regulatory sequences that are much more complex that those of the la ...

Gene expression profiling
In the field of molecular biology, gene expression profiling is the measurement of the activity (the expression) of thousands of genes at once, to create a global picture of cellular function. These profiles can, for example, distinguish between cells that are actively dividing, or show how the cells react to a particular treatment. Many experiments of this sort measure an entire genome simultaneously, that is, every gene present in a particular cell.DNA microarray technology measures the relative activity of previously identified target genes. Sequence based techniques, like serial analysis of gene expression (SAGE, SuperSAGE) are also used for gene expression profiling. SuperSAGE is especially accurate and can measure any active gene, not just a predefined set. The advent of next-generation sequencing has made sequence based expression analysis an increasingly popular, ""digital"" alternative to microarrays called RNA-Seq. However, microarrays are far more common, accounting for 17,000 PubMed articles by 2006.
