Transcription profiling of Drosophila eye antennal imaginal disc expressing either activated Ras or secreted Spitz

ABSTRACT: We have used microarrays to identify genes expressed and required for the second mitotic wave (SMW) during eye development. Eye discs expressing Spitz under the control of GMR Gal4 have no SMW as Spitz promotes G1 arrest, ectopic differentiation also occures. To control for the ectopic differentiation, Spi expressing eye antennal discs were compared to eye antennal discs expressing activated RasV12. In discs expresseding RasV12 under the control of GMRGal4 the SMW takes place normally prior to any ectopic differentiation. We used microarrays to detail the global programme of gene expression underlying cellularisation and identified distinct classes of up-regulated genes during this process. Experiment Overall Design: Drosophila eye antennal imaginal discs expressing either UAS RasV12 or UA
