Primary source abstract: "Here, [investigators] report the characteristics of the regulatory network orchestrating early mesodermal development in the fruitfly Drosophila, where the transcription factor Twist is both necessary and sufficient to drive development. Through the integration of chromatin immunoprecipitation followed by microarray analysis (ChIP-on-chip) experiments during discrete time periods with computational approaches, [they] identified >2000 Twist-bound cis-regulatory modules (CRMs) and almost 500 direct target genes." |
| Comments |
P.30 right column top paragraph: "Even greater is the number of target genes directly regulated by the Drosophila Twist transcription factor during embryogenesis—nearly 500 targets in total, including genes involved in cell proliferation, cell migration, and morphogenesis, as well as nearly one-fourth of all known transcription factor genes (primary source)." P.30 right column 2nd paragraph: "The
scale of the Twist-regulated network, for example, means that, in the course of evolution, some 500 linkages have
evolved between Twist and different CREs [cis-regulatory elements]." |
