Neutralizing antibodies (nAB) at the time of administration hamper the effectiveness of adeno-associated virus (AAV) as a clinical DNA delivery system. The present study was designed to investigate if AAV re-administration in muscle tissue is dependent on the nAB titer. Recombinant (r)AAV serotype 1, as a promising candidate for targeting skeletal muscle,(More)
A single plasmid regulated expression vector based upon a mifepristone-inducible two plasmid system, termed pBRES, has been constructed and tested in mice using murine interferon-b (mIFNb) as the transgene. The expression of mIFNb in the circulation was followed by measuring the systemic induction of IP-10, a validated biomarker for mIFNb in mice.(More)
Vessel wall inflammation and matrix destruction are critical to abdominal aortic aneurysm (AAA) formation and rupture. We have previously shown that urokinase plasminogen activator (uPA) is highly expressed in experimental AAA and is essential for AAA formation and expansion. In this study, we examined the effects of overexpression of a natural inhibitor of(More)
Gene delivery of angiogenic growth factors is a promising approach for the treatment of ischemic cardiovascular diseases. However, success of this new therapeutic principle is hindered by the lack of critical understanding as to how disease pathology affects the efficiency of gene delivery and/or the downstream signaling pathways of angiogenesis. Critical(More)
Mobilization and recruitment of bone marrow-derived progenitor cells (BMDPCs) play an important role in postischemic tissue repair. Patients with coronary artery disease (CAD) or peripheral vascular disease (PVD) exhibit endothelial dysfunction, and as a result are likely to have a reduced number of progenitor cells mobilized in their peripheral circulation(More)
