Co-expression vs coregulation

From co-expression to co-regulation: how many microarray experiments do we need?

www.ncbi.nlm.nih.gov/pubmed/15239833

The primary thrust of this paper is to provide guidance to
researchers who wish to use cluster analysis of gene expres-
sion data to identify co-regulated genes.

We define co-
expressed genes as genes that share similar expression pat-
terns as discovered by cluster analysis, and we define co-reg-
ulated genes as genes that are regulated by at least one
common known transcription factor.
