- Multidrug-Resistance like Proteins (MRPs) are ubiquitously expressed essential transporters required for many biological processes. Previous studies revealed that MRPs are pivotal for transporting endo- and xenobiotics, conferring resistance to anti-cancer agents and contributing to clearance of oxidative products. Nonetheless, their functions in other biological processes are still unclear. In our investigation, we suppress the expression of Drosophila Multidrug resistance like Protein 1 (MRP) in Malpighian tubules, the functional equivalent to the human kidney, and find this is sufficient to cause abnormal lipid accumulation, as well as disrupt normal feeding patterns. In addition, we suggest that the elevation of lipid contents may be a result of increasing Hr96 (homolog of human Pregnane X receptor) expression, which is known to play a role in detoxification and lipid metabolism processes. Finally, we validate that Malpighian tubules-specific MRP deficiency increases oxidative resistance in fruit flies. In summary, our results demonstrate that inadequate MRP expression in Malpighian tubules can lead to disrupted lipid homeostasis and feeding behavior. However, it may also elevate the oxidative resistance of the flies.
