 * We describe the use of singular value decomposition in transforming gene expression data from genes/arrays space to ‘‘eigengenes’’/‘‘eigenarrays’’ space, where the eigengenes and eigenarrays are unique orthonormal superpositions of the genes and arrays, respectively.

 * After normalization and sorting, the significant eigengenes and eigenarrays can be associated with observed genome-wide effects of regulators, or with measured samples, in which these regulators are overactive or underactive, respectively.

 * Significantly correlated with the first eigengene were GO terms that we classified as being broadly associated with ‘‘metabolism’’ because this cluster was enriched for genes involved in the tricarboxylic acid cycle (TCA), the electron transport chain, metabolism, ATP synthesis, and protein degradation.

 * Each module is represented by an ‘eigengene’ corresponding to its expression pattern across structures (first left singular vector of the gene × structure matrix), and genes highly correlated with the module eigengene are called ‘hub’ genes.

 * Our gene expression data also indicate that the cystoskeleton is sensitive to shifts in temperature and pCO2: genes encoding fundamental components of the cellular cytoskeleton such as actin and alpha and beta tubulins were upregulated under elevated temperature, but downregulated under elevated pCO2 (eigengene 1).

 * The second most significant pattern identified by SVD corresponds to broad upregulation of gene expression midway through embryogenesis and is strikingly similar to the coordinate induction of glycolytic genes that defines the embryonic metabolic transition (EmbMT) (eigengene pattern 2).

Inventor of the eigengene, she pioneered the matrix and tensor modeling of large-scale molecular biological data, which, as she demonstrated, can be used to correctly predict previously unknown cellular mechanisms.
