Cancer cells often alter metabolism to support their malignant phenotype. Despite the advances in research connecting metabolism and cancer, we still do not know how these metabolic changes happen in a cell, and how they trigger and support malignant phenotypes. Multiple lines of evidence show that the peroxisome, an organelle which breaks down fats and other chemicals in the cell, can tune a cell’s metabolism to support or stop from becoming cancerous. This finding is very important because it reveals a previously unexplored fundamental player in the cell machinery that regulates tumorigeneis. My laboratory uses Drosophila melanogaster, or fruit flies, to study peroxisomes and their role in intestinal cancer. The fruit fly Drosophila melanogaster is a good model system as their genes can be easily manipulated. Also, Drosophila have the same genes related to cancer formation (oncogenes) and inhibition (tumor suppressors), as found in humans. For these reasons the fly has been used to study the mechanisms that induce different cancer in humans, in particular colon cancer.
