Research Interest: Dr. Thornburg’s research has focused on the placental and fetal mechanisms
that underlie programming. He is currently pursuing studies on the role of the role of Ang II in regulating placental transport proteins, placental-fetal fluid balance in regulating heart
development, and differential gene expression in placental under- and over-growth.

Kevin Wei, MD
Associate Professor of Medicine (OHSU)
Clinical Focus: Dr. Wei sub-specializes in noninvasive cardiac imaging and has a clinical interest
in myocardial contrast echocardiography. Research Interests: Dr.Wei has focused his research on the evaluation of pathophysiologic
changes in the microcirculation in the setting of coronary artery disease, and has applied these
phenomena to the noninvasive detection and quantification of stenoses with myocardial contrast echocardiography.
Recently, his translational research has extended observations made in the animal laboratory to The patient, and ongoing studies are evaluating the clinical utility of contrast echocardiography
in the Emergency Department, as well as the role of the microvasculature in other cardiac diseases.

Joseph B. Weiss, MD, PhD
Assistant Professor of Molecular Medicine & Cardiology (OHSU) [email protected]
Clinical Focus: Dr. Weiss practices general cardiology with a specific focus on adult congenital
heart disease.
Research Interests: The Weiss lab studies heart and smooth muscle development in
Drosophila and mice. This accomplished research group takes advantage of the evolutionary
conservation of developmental mechanisms and the power of developmental genetics in Drosophila to advance our understanding of mammalian organogenesis. One striking example of
conserved developmental mechanisms is the homeodomain protein Tinman. Homozygous
Drosophilia tinman mutant embryos have neither heart nor smooth muscle. Heterozygous human mutants in the Tinman homologue Nkx2.5 evince a broad spectrum of congenital heart lesions.
Starting with this evolutionarily conserved transcriptional regulator of heart and smooth muscle development, we have established a method to identify genes that are direct targets of Tinman
regulation.
Zhengfeng Zhou, MD, PhD
Assistant Professor of Medicine (OHSU)
Assistant Professor of Physiology and Pharmacology
Research Interests: The research in Dr. Zhou’s lab is to study molecular mechanisms of
genetic diseases involving cardiac arrhythmias. They have concentrated their studies on two
congenital diseases, long QT syndrome (LQTS) and arrhythmogenic right ventricular dysplasia (ARVD). LQTS is a disease associated with prolonged cardiac action potential duration and
prolonged QT intervals on ECG, which can lead to ventricular arrhythmia and sudden death. One of
the major forms of LQTS (LQT2) is caused by mutations in the human ether-a-go-go-related gene (hERG) that encodes a voltage-gated potassium channel in the heart. To date, more than 300 hERG
mutations have been identified in patients with LQTS. Current studies are investigating the mechanisms of defective protein trafficking of LQT2 mutant channels, and determining how LQT2
mutations lead to defects in splicing and stability of mutant mRNA. ARVD is an inherited disorder
characterized by prominent arrhythmias and the replacement of muscle in the heart by fatty tissue. Eight disease-causing genes have been identified in autosomal dominant and recessive forms of
ARVD. Most of these genes encode desmosomal proteins including plakoglobin, desmoplakin, plakophilin-2, desmoglein-2, and desmocollin-2. A prominent feature of ARVD mutations is that
more than 60% of these mutations are nonsense or frameshift mutations that introduce premature termination codons. The goal of this project is to determine the role of the nonsense-mediated
mRNA decay (NMD) pathway in the pathogenesis of ARVD mutations. Understanding how these
genetic defects lead to the disease at molecular levels will provide important information directed toward the development of therapeutic strategies for patients with LQTS and ARVD.
