Transient transfection experiments in which three different estrogen response element-containing reporter genes were cotransfected into HeLa cells, together with constitutively expressed estrogen receptor (ER) constructs, demonstrate that activation of the transcription of the reporter genes by epidermal growth factor (EGF) and by cholera toxin with 3-isobutyl-1-methyl-xanthine, which elevate c...
Xanthine oxidase (X0) has been thoroughly studied by many investigators and the range of possible substrates of this enzyme is well known (1, 2). In the early experiments, enzymatic activity was measured by decolorization of a suitable dyestuff such as methylene blue or by oxygen consumption. Therefore, the exact pathway of oxidation remained unknown for many substrates. The spectrophotometric ...
Background: Reactive oxygen species (ROS) contribute to development of neuropathic pain. A neuropathic pain syndrome was produced in rats following prolonged hindpaw ischemia/reperfusion injury, creating an animal model of complex regional pain syndrome-Type I (CRPS-I). This study was designed to evaluate the validity of this model for ROS and pain research. Herein we show superoxide produces N...
Myocardial dysfunction contributes to the high mortality of patients with endotoxemia. Although nitric oxide (NO) has been implicated in the pathogenesis of septic cardiovascular dysfunction, the role of myocardial NO synthase 3 (NOS3) remains incompletely defined. Here we show that mice with cardiomyocyte-specific NOS3 overexpression (NOS3TG) are protected from myocardial dysfunction and death...
The influence of dietary molybdenum on esophageal carcinogenesis induced by N-methyl-N-benzylnitrosamine (2.5 mg per kg of body weight once a week for 20 wk s.c.) was studied in male F344 rats. The tumor incidence and tumor development in the esophagus were significantly lower in the rats in the high-molybdenum (2 ppm) diet group than in the rats in the low-molybdenum (0.032 ppm) diet group; i....

Introduction: Physalis alkekengi (Solanaceae) is a rich source of various antioxidants. There are some reports that show P. alkekengi has been used for treatment of a wide range of diseases including gout and inflammation. Xanthine oxidase plays a crucial role in gout. Many natural compounds such as various flavonoids have been reported to have inhibitory effect on xanthine oxidase. Metho...
