ABSTRACT
Drosophila melanogaster is a proven metazoan model to investigate the fundamentals of human genetic diseases including peroxisome-related disorders. Drosophila have facile cell and animal culture but with a relatively simpler genome and organ morphology compared to vertebrates. Drosophila Schneider 2 (S2) cells have been used extensively as a platform for investigating peroxisome functions like transport along the cytoskeleton via their amenability to RNA-interference (RNAi)-based gene knockdown. Similarly, novel findings regarding tissue-specific roles for peroxisomes have come from studies in developing flies. Individual organs can be targeted for RNAi or gene mutations affecting a limited group of cells in the context of the entire animal. Here, we provide basic protocols on how to visualize peroxisomes and manipulate expression of the Peroxin or other peroxisome genes in S2 cells and developing Drosophila organs.
