Endothelial nitric-oxide synthase (eNOS) is regulated by signaling pathways involving multiple sites of phosphorylation. The coordinated phosphorylation eNOS at Ser<sup>1179</sup> and dephosphorylation Thr<sup>497</sup>activates the enzyme, whereas inhibition results when Thr<sup>497</sup> phosphorylated dephosphorylated.

This study determined the role of body temperature during chronic exercise on myocardial stress proteins and antioxidant enzymes as well functional recovery after an ischemic insult. Male Sprague-Dawley rats were exercised for 3, 6, or 9 wk in a 23°C room (3WK, 6WK, 9WK, respectively) 4–8°C environment with wetted fur (3WKC, 6WKC, 9WKC, respectively). The colder prevented elevations core temperature. During weeks 3–9 animals ran 5 days/wk up 6% grade at 20 m/min 60 min. Myocardial heat shock...

3-Hydroxy-3-methylglutaryl (HMG)-CoA reductase inhibitors, statins, provide beneficial effects independent of their lipid-lowering effects. One effect appears to involve acute activation endothelial nitric oxide (NO) synthase (eNOS) and increased NO release. However, the mechanism statin-stimulated eNOS is unknown. Therefore, we hypothesized that may be coupled altered phosphorylation. Bovine aortic cells (BAECs), passages 2-6, were treated with either lovastatin or pravastatin from 0 30...
