Radiotracer and biochemical studies have shown that patients with Parkinson disease lack functional sympathetic innervation to the heart. The same observation was made in mice treated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), an experimental model of Parkinson disease. This study examined the mechanical properties, adrenergic receptor level(More)
Insulin-like growth factor-I (IGF-1) ameliorates cardiac dysfunction in diabetes although the mechanism of action remains poorly understood. This study examined the role of PI-3 kinase/Akt/mammalian target of rapamycin (mTOR) and calcineurin pathways in cardiac effects of IGF-1 against glucose toxicity. Adult rat ventricular myocytes were cultured for 8 h(More)
Diabetic cardiomyopathy is characterized by cardiac dysfunction and altered level/function of insulin-like growth factor I (IGF-I). Both endogenous and exogenous IGF-I have been shown to effectively alleviate diabetes-induced cardiac dysfunction and oxidative stress. This study was designed to examine the effect of cardiac overexpression of IGF-I on(More)
Chronic alcoholism can progress to alcoholic cardiomyopathy characterized by ventricular dilation and impaired ventricular contractility. Nicotine abuse continues to remain a serious risk factor for cardiovascular diseases. However, little is know regarding the combined effects. This study was designed to examine the role of short-term combined exposure of(More)
