beta-Lapachone, a 1,2-naphthoquinone, is a novel chemotherapeutic agent. It has been shown to be capable of suppressing inducible nitric oxide synthase expression and function in rat alveolar macrophages. The authors further performed experiments to examine the molecular mechanism of beta-lapachone on LPS-induced responses in rat alveolar macrophages and to(More)
Long-term exposure to particulate air pollution has been implicated as a risk factor for cardiovascular disease and mortality. Short-term exposure has also been suggested to contribute to complications of atherosclerosis. Aberrant regulation of smooth muscle cell proliferation is thought to associate with the pathophysiology of vascular disorders such as(More)
Benzo[a]pyrene, a ubiquitous environmental pollutant, has been suggested to be capable of initiating and/or accelerating atherosclerosis. Accumulation of vascular smooth muscle cells (VSMCs) in vessel intima is a hallmark of atherosclerosis. Nitric oxide (NO) can suppress VSMCs proliferation and induce VSMCs apoptosis. NO plays a compensatory role in the(More)
