Research

The majority of cardiovascular disease results from complications of vascular disorders, e.g., atherosclerosis that becomes worse under the circumstance with obesity and diabetes. Dr. Cui has a research interest in vascular biology with special reference to the vasculopathy associated with obesity and diabetes. Dr. Cui’s laboratory takes a multi-disciplinary approach to address the molecular and cellular mechanism that links obesity, diabetes and vascular disease, with a specific focus on the role of ubiquitin-proteasome system in the maintenance of vascular homeostasis. 

There are four areas of technical strengths in Dr. Cui’s laboratory: 1) molecular biology including most of the routine DNA, RNA and protein techniques; 2) cellular biology including primary culture of vascular smooth muscle cells, endothelial cells, macrophages and adipocytes, dissection of signal transduction pathways involved in cellular metabolism, migration and proliferation as well as inflammatory responses; 3) development and characterization of animal models of vascular disease through transgenic approaches; 4) vascular physiology analyses in cell, organ and whole animal levels. 

Two major projects currently underway include:

  1. Defining mechanism that regulates Keap1-mediated Nrf2 ubiquitination, degradation, anti-oxidative gene expression in vasculature.
  2. Determining mechanism that controls the deubiquitinating enzymes such as UCH-L1- or CYLD-mediated suppression of inflammatory responses in vasculature.
