Research Description

Cancer and Neurodegenerative diseases are two most clinically problematic classes of disease impacting the world's aging populations. Although there are apparently opposite phenotypes between cancer cells and degenerated neurons, common molecular mechanisms might be involved in dysregulated cancer cell growth and the progression of neurodegenerative disease. Our laboratory is using Drosophila system to study the basic molecular mechanisms and crosstalk of cell growth and neurodegenerative cell death. The ultimate goal of research is to help cure both diseases. Specifically, research will focus on the following areas:

1. Organisms are able to respond appropriately to nutrient flux to increase their size and cell number so called ‘growth’. Problems in growth process lead to lots of severe diseases, for example, cancer can be considered overgrowth of cells. The Target of Rapamycin (TOR) has central roles in controlling growth of cells, tissues and organisms by generation of TOR complex 1 (TORC1) and TOR complex 2 (TORC2). We are using genetic system to learn the basic mechanisms of TORC1 in response of stress, upstream signals and downstream targets of TORC2 in the cell growth pathway, and the mechanisms of TOR’s effect on aging. The ultimate goal of our lab is to establish an entire network of TOR in response of nutrition, growth factors, hormones and stress.

2. In metazoans, the coupling of cell growth and cell death together controls the tissue homeostasis. Understanding neurodegenerative diseases not only benefits cell death related diseases, but also arises the treatment option for growth related diseases such as cancer. In our lab, we are usingDrosophila model to study the pathogenesis of neurodegenerative diseases especially Parkinson's disease (PD). We are trying to identify the upstream signal of Pink1 and downstream targets of Parkin in mitophagy pathway; understand the genetic interaction between major PD associated genes, Pink1, Parkin, DJ-1 and LRRK; screen for suppressors of PD animals. In the end, the therapies or drug targets of PD might be presented.

3. Retinal degeneration and vision loss is one of the major health problems, afflicting ~300 millions of people worldwide. However, in most cases, the underlying mechanisms responsible for retinal degenerations are still poorly understood, hence have very few effective treatments. The goals of our research are to exploit Drosophila as a model organism for characterizing the mechanisms underlying phototransduction and Retinal Degenerations, and to explore strategies for suppressing these types of neuronal cell death.
