Lee Ann MacMillan-Crow, Ph.D. (Pharmacology and Toxicology) Web profile 
Our laboratory has been investigating the role that increased mitochondrial oxidant production has on the early events leading to renal dysfunction following renal preservation and warm ischemia/reperfusion (I/R) in vivo. Previous studies have suggested that inactivation of the major antioxidant within the mitochondria, manganese superoxide dismutase (MnSOD), plays a pivotal role in inducing renal injury during I/R injury. Using both cell and rodent models we are also assessing the therapeutic potential of known and novel antioxidants to alter I/R and transplantation induced renal dysfunction.

Our research group uses biochemistry, molecular biology, physical chemistry, and organic chemistry to answer questions concerning the pathogenesis of vitamin-related birth defects and anemia of low birth weight infants.

Roy Morello, Ph.D. (Physiology and Biophysics and Genetics) Web profile
In my laboratory we study the function of novel genes, in particular those involved in bone formation, development, homeostasis and disease. We utilize the power of mouse gene targeting and conditional gene-inactivation techniques to generate ubiquitous or tissue-specific mutations in the mouse. With the use of cell biology, biochemistry, cell microscopy and genetic approaches we characterize the phenotype of these mice to understand the underlying gene function. The objective is to learn from the animal model and make correlations with relevant aspects of human disease and hence gain mechanistic insights of biological function.

Steve Post, Ph.D. (Pathology)
Our lab studies the coupling of specific receptors and signaling pathways to cell function and disease. Of particular interest are the regulation of macrophage scavenger receptors and their role in chronic inflammation. Another area of interest relates to understanding the signaling pathways that regulate cardiac myocyte survival.
