Key Points

To develop and validate ARACNE, an information-theoretic algorithm designed to reconstruct complex mammalian gene regulatory networks from microarray expression profiles by eliminating indirect interactions.
Applied an information-theoretic framework relying on mutual information to eliminate indirect statistical interactions inferred from gene expression data.
Evaluated reconstruction accuracy against Relevance Networks and Bayesian Networks using synthetic expression datasets and an experimental microarray dataset from human B cells.
ARACNE demonstrated low error rates on synthetic network models, outperforming Relevance Networks and Bayesian Networks even in the presence of complex loops.
Analysis of human B-cell expression profiles successfully inferred experimentally validated transcriptional targets of the cMYC proto-oncogene.
Algorithms based on mutual information ranking exhibited superior resilience to estimation errors compared to standard mutual information cutoffs.
