The Yin and Yan of border cell migration
Invasive cell migration a feature of both normal development and
metastatic cancer is regulated by numerous signalling pathways,
transcription factors and cell-adhesion molecules, the coordination of which
is poorly understood. Now, on
p. 3493, Schober and
colleagues report that the ETS transcription factor Yan is a key regulator of
the stereotypic migration of border cells during Drosophila
oogenesis. The researchers show that Yan is dynamically expressed and
regulated by the Notch, JAK/STAT and RTK signalling pathways in border cells
during their migration, and that increased or decreased Yan activity delays
their migration by affecting the turnover of the cell-cell adhesion molecule
E-cadherin. ETS transcription factors are often upregulated in invasive
tumours, note the researchers, so these results provide important mechanistic
insights not only into the control of developmental invasive cell migration
but possibly also into pathological cell migration.
