Abstract
Ribosome biogenesis is critical for the proper production of proteins in cells and has emerged as a regulator of cell invasion and migration in development and in cancer. The Drosophila border cells form a collective that invades and migrates through the surrounding tissue during oogenesis. We previously found that a significant number of ribosome biogenesis genes are differentially expressed from early to late migration stages. Here, we performed a small-scale RNAi screen of a subset of these ribosome genes. Knockdown of seven genes disrupted border cell migration, thus revealing a role for ribosome biogenesis genes in regulating collective cell migration.
