Research Summary:
The Pharmacology of COX and mPGES-1 Inhibition
A particular interest is to elucidate the cardiovascular biology of COXs, their downstream isomerases and receptors activated by prostaglandins. Currently lipidomic, genomic and proteomic approaches are being integrated in mice and zebrafish to complement studies of the role of bioactive lipids in human physiology and disease.

Research Summary:
Eicosanoid Receptor Biology
Prostacyclin has potent vasodilator and platelet inhibitory properties. However, its role in vivo is poorly understood. Mice deficient in the prostacyclin receptor and mice overexpressing and lacking the thromboxane receptor have been employed to investigate this phenomenon. Current research also utilizes genomic and proteomic approaches to interrogate the role of membrane receptors for distinct prostanoids in inflammation and cardiovascular biology and to identify novel lipid ligands for nuclear receptors.

Research Summary:
Isoeicosanoids
Isoeicosanoids are free radical catalyzed products of arachidonic Isoeicosanoids are free radical catalyzed products of arachidonic acid with potential utility as indices of oxidant stress. Methods for analyzing representatives of distinct families of isomers continue to be developed. Alterations in isoeicosanoid generation are being related to indices of oxidant injury to DNA and protein and to functional outcome in syndromes of oxidant injury in model systems and in humans.

Research Summary:
Peripheral molecular clocks
We identified a molecular clock in the vasculature and provided the first evidence for a mechanism by which a hormone could phase shift a peripheral clock. More recently, we have implicated core clock genes in the regulation of glucose homeostasis. Ongoing work seeks to define the mechanisms by which peripheral clocks regulate cardiovascular and metabolic function, the mechanisms by which they communicate with the master clock in the suprachiastmic nucleus and the mechanisms which differentiate peripheral clock function in distinct tissues.

FitzGerald Laboratory Clinical Trials Unit
This Clinical Trials Unit within the Institute for Translational Medicine and Therapeutics is initially focused on protocols designed to explore cardiovascular disease and inflammation. Specifically, studies involve both mechanistic studies in volunteers and patient populations and large scale genomic analyses, particularly involving the use of the IBC (ITMAT - Broad- CARE) array, a 50K SNP array for large-scale interrogation of vascular disease cohorts. The manager assists the investigators in protocol and budget development and study design, creates consent forms and other study documents, and handles all regulatory committee submissions. Other responsibilities include supervising the research staff and managing study set-up and progress of the protocols. A dedicated and diversified team of research coordinators then implements the protocols by recruiting the subjects, ascertaining their eligibility, and scheduling and directing the study visits to the Clinical and Translational Research Center. Meticulous record keeping and data management, utilizing case report forms and electronic databases, are also key components of the entire research team to successful study completion and data analysis.
