摘要: Abstract Circadian rhythm is fundamentally important in physiological processes of mammals. To reveal its underlying mechanism, we probed functional interactions among genes, motivated by the basic molecular observation on gene expression data circadian that a large number genes oscillate coordinated manner. In this study, reverse-engineering strategy was applied to infer and analyze structure function rhythm-related regulatory network. Specifically, our method integrated four phase-shift time-course datasets rat suprachiasmatic nucleus, protein–protein interactions, phosphorylations set key prior information cis-regulatory elements, construct network related rat. By follow-up analysis, identified new hubs may play crucial roles regulation rhythm. Furthermore, found feedback loop motifs were significantly en...
