Genome-wide expression profiling in Drosophila wing imaginal discs

ABSTRACT: The imaginal discs of Drosophila melanogaster, where most known Hedgehog (Hh) signaling target genes are expressed with a restricted pattern, offers an accessible model system for identifying novel targets of the Hh signaling pathway. In the wing discs, cells near the A/P compartment boundary (B: ptc+) receive the highest level of Hh stimulation, A cells (A: hh-) further from the border receive lower levels of stimulation, while P cells (P: hh+) do not respond to Hh. To identify target genes whose expression is controlled by Hh signaling activity, we performed a systematic comparison of gene expression profiles among the A cells (A: hh-), the A cells adjacent to the A/P compartment boundary (B: ptc+), and P cells (P: hh+) via microarray analysis.
