Figure 1. Demo result of WGCNA network service.
Demo result interpretation
The calculation based on weighted co-expression uses the division of modules of average hierarchical clustering, the correlation between modules and traits, selects significant traits, and constructs corresponding network diagrams to find core genes related to traits.
Features
Weighted gene co-expression network analysis (Weighted gene co-expression network analysis, WGCNA) is also named the weighted gene co-expression network analysis. According to different gene expression patterns, the basic idea is to mine genes with similar expression patterns, defined as a module. Genes with similar expression patterns are likely to be closely co-regulated. Closely related functions or members of the same signaling pathway or process have specific physiological significance.
Overall solutions
CD ComputaBio We will look for co-expressed gene modules, and explore the relationship between the gene network and the phenotype of interest, as well as the core genes in the network.
Summary and workflow
Once the β value for constructing the network is selected, four steps are required from network construction to module identification.
Step 1: calculate the dissimilarity between every two genes through topological overlap.
The similarity between two genes is calculated by topological overlap (TOM).
Step 2: get the gene cluster tree
According to the similarity between gene expression, hierarchical clustering is performed. Then through the dissimilarity conversion between genes, a gene cluster tree is obtained.
Step 3: Divide the expression consistent genes into the same module by cutting the tree.
Step 4: Merge similar modules
