Abstract excerpt
A critical question about signal transduction is how weak or transient activation of signaling pathways achieves a robust and long-term switch in gene expression. We report that a microRNA is part of a mechanism that makes cells sensitive to signals in the Drosophila eye. Expression of miR-7 is activated in cells as they begin differentiating into photoreceptors. This is dependent on EGF receptor (EGFR) signaling...
