WormNet v. 1 is a probabilistic functional gene network of
protein-encoding genes of C. elegans,
constructed using a modified Bayesian integration of many different data types from several different organisms, with each data type weighted according to how well it links genes that are known to function together in C. elegans. Each interaction in WormNet has an associated log-likelihood score (LLS) that measures the probability of an interaction representing a true functional linkage between two genes.
To search WormNet please go to the basic search page and enter a gene, or list of genes, in the box provided, using Wormbase public or sequence gene names (e.g. dys-1 or F15D3.1). The search will return all of the genes that are directly connected to an input gene (or set of genes), ranked according to their log-likelihood scores. The evidence for each interaction is indicated using the codes listed at the bottom of this page. WormNet is built on Wormbase release WS140 gene identifiers. Current network statistics
Reference: A single network comprising the majority of genes accurately predicts the phenotypic effects of gene perturbation in C. elegans Insuk Lee, Ben Lehner, Catriona Crombie, Wendy Wang, Andrew G. Fraser, and Edward M. Marcotte Nature Genetics, Vol 40, p181-188 (2008) Basic search with graph layout This reports all connected WormNet neighbors to your query genes. Coherence of query genes is measured by area under the receiver operating characteristic (ROC) curve (AUC) spaning from 0.5 (for no-coherence) to 1 (for maximum-coherence). High AUC (e.g., > 0.65) is considered as predictive. If you see high AUC for genes from your initial screen, their top neighbors would be good candidates for your follow-up screen, network-guided focused screen. This search has seed gene set size limit of 250, and shows graph layouts as well. Basic search with NO graph layout Same as above except allowing seeding up to 2,000 genes, but no graph layout Advanced search This predicts Gene Ontology (GO) biological process terms for query genes based on WormNet.
