Wiring diagram gene regulatory network. Pending yes introduction genetic interactions occur when mutations in two or more genes combine to generate an unexpected phenotype. Gene networks that retain similar wiring diagrams in diverse and distantly related organisms point to the ways in which regulatory regions of the genome evolve. This comprehensive network maps genetic interactions for essential gene pairs highlighting essential genes as densely connected hubs. Integrating techniques from mathematics.

This article focuses on a necessary prerequisite to dynamic modeling of a network. More specifically we focus here on inference of biological network structure using the growing sets of high throughput expression data for genes proteins and metabolites. The global network illustrates how coherent sets of genetic interactions connect protein complex and pathway modules to map a functional wiring diagram of the cell. If the gene expression is above a set threshold the corresponding state is 1 otherwise 0.

The network of regulatory relations. Let f f k p k p k k 1 n be an sdds and g be the wiring diagram associated with f. That is g has nodes x 1 x n and there is a directed edge from x i to x j if f j depends on x i. The following four network diagrams illustrate portions regulatory gene network for ectoderm specification.

These four view from all nuclei vfa diagrams include the mesomere lineages network 6 to 17 hours oral animal ectoderm 18 to 30 hours lateral and aboral animal ectoderm 18 to 30 hours and veg1 ectoderm 21 to 30 hours. In this model gene expression data are discretized and presented by two values. 1 as a negative regulator of the akt pathway a key signalling cascade frequently deregulated in cancer. Animal development and behavior present special challenges to biologists because these processes are complex and context dependent the idea that complicated biology can be represented as networks is at the heart of both developmental and behavioral biology.

Inference of the topology that is prediction of the wiring diagram of the network. While this survey of methods to reverse engineer gene networks in the form of a wiring diagram is far from complete it provides a ???avor of the variety of approaches the scale at which the methods are being applied and the challenges that result from a lack of appropriate experimental data.
