The Hippo pathway, a complex growth regulation signaling pathway, affects organ size and development in Drosophila and when dysregulated can lead to tumor development. A gene first found in mice, the vib or vibrator gene, may affect the Hippo pathway and fly organ development. This project aims to examine the function of the vib gene in conjunction with the Hippo pathway by using vib mutant clones and analyzing the morphological changes in their wings.
