ACCEPTING DOCTORAL STUDENTS
The Zhang lab studies lipid signaling pathways that are involved in development and diseases by developing novel chemical probes and technologies. As key components of cellular membranes, lipids also serve as signaling molecules and modify functions of proteins through either covalent or non-covalent interactions. Dys-regulation of lipid signaling has been correlated with various diseases including cancer, diabetes, and neurodegenerative diseases. Consequently, many lipid-related proteins or processes have been used as therapeutic targets. However, lipids are dynamically metabolized and transported, making it difficult to illustrate the roles of lipids in development and diseases with limited availability of probes and technologies for lipid studies.
The active projects in the lab include:
1. Develop chemical tools to monitor and regulate activity of the phospholipase C isozymes.
2. Novel approaches to targeted and untargeted profiling of lipid signaling pathways.
3. Investigate cellular functions of lipids in different cellular processes, particularly those regulated by small GTPases.
Research in the Zhang lab is focused on understanding the roles of endogenous small molecules, particularly phospholipids, in cell signaling events that are responsible for both normal development and diseases. Phospholipids play essential roles in all living organisms. Other than being major membrane constituents in cells, many phospholipids function as signaling molecules. Consequently, abnormal levels of phospholipids and aberrant regulation of their metabolizing enzymes have been associated with onset and progression of various diseases. However, how phospholipid signaling pathways regulate normal development and diseases is still poorly understood, largely due to their dynamic metabolism in the cells and the lack of available reagents and assays for phospholipids and their metabolic enzymes. I am interested in three different approaches to profile and understand phospholipids: 1) Develop small molecule sensors and modulators for different phospholipid metabolizing enzymes; 2) Develop efficient methods and technologies to profile phospholipids and use the resulting data for precision medicine and identification of new signaling molecules; and 3) Investigate cellular functions of known and unknown phospholipids, particularly their synergistic actions with small GTPases ADP-ribosylation factors in regulating protein trafficking in signaling transduction. More recently, we have also extended our efforts to drug discovery towards diseases (particularly cancer and neurodegenerative diseases) where phospholipid metabolizing enzymes are dysregulated. Toward this end, we are constructing library of small molecules with unique structures and functions.
