title: Breaking a temporal barrier: signalling crosstalk regulates the initiation of border cell migration.
abstract: Correct timing of developmental events is crucial for generating a normal organism. During oogenesis in Drosophila melanogaster, migration of border cells occurs in a defined temporal window and requires Jak/Stat and steroid hormone signalling. The initiation of border-cell migration is now shown to be timed by Jak/Stat-mediated downregulation of the BTB domain transcriptional regulator Abrupt, which acts as a negative regulator of steroid hormone signalling.
