Pair-wise Interactions in Gene Expression Determine a Hierarchical Transcription Profile of the Human Brain
Abstract
Orchestrated expressions of tens of thousands of genes give rise to the complexity of the brain. However, it is unclear what is the structure governing these myriads of gene-gene interactions. By analyzing the transcription data obtained from more than 3000 sites in human brains, we found that pair-wise interactions between genes are sufficient to accurately predict both the transcription pattern of the whole genome for individual brain areas and the transcription profile of the entire brain, suggesting a surprisingly simple interaction structure of the transcriptome itself. We further revealed that the strength of gene-gene interaction observed empirically allows the nearly maximal number of transcriptionally similar clusters of areas to form, which may account for the functional and structural richness of the brain. One Sentence SummaryPairwise interactions among genes shape the overall structure of human brain transcriptome.
