Cluster-based network model for time-course gene expression data
Inoue, Lurdes, Neira, Mauricio, Nelson, Colleen, Gleave, Martin, & Etzioni, Ruth (2007) Cluster-based network model for time-course gene expression data. Biostatistics, 8(3), pp. 507-525.
We propose a model-based approach to unify clustering and network modeling using time-course gene expression data. Specifically, our approach uses a mixture model to cluster genes. Genes within the same cluster share a similar expression profile. The network is built over cluster-specific expression profiles using state-space models. We discuss the application of our model to simulated data as well as to time-course gene expression data arising from animal models on prostate cancer progression. The latter application shows that with a combined statistical/bioinformatics analyses, we are able to extract gene-to-gene relationships supported by the literature as well as new plausible relationships.
