Chronic changes in blood flow (shear stress) occur in physiological (growth, pregnancy, exercise) and pathological conditions (post-ischemic revascularization). Changes in flow induce a remodeling aimed at normalizing wall shear stress. This remodeling requires an initial inflammatory response, oxidative stress and the production of NO. Peroxynitrite activate MMPs and matrix degradation.
We have shown that this remodeling does not occur in aging although this defect is reversible using a vasodilator treatment. We are now investigating flow-mediated remodeling in resistance arteries in aging in association with obesity and diabetes, which are more currently occurring in older subjects, and, in addition, the frequency of these disorders is dramatically increasing worldwide.
We have discovered that high-flow remodeling decreases with age in male rats and is absent after 12 months. High-flow remodeling is absent in young diabetic rats but preserved in obese 12-month-old rats due to the production of COX-2-derivared prostacycline. Nevertheless, in both diabetic and obese rats, endothelium (NO)-mediated dilation decreases in arteries submitted chronically to high blood flow instead of increasing as seen in healthy animals. In diabetic rats, the activation of MMPs by peroxinitrites is severely reduced, thus preventing digestion of the extracellular matrix and consequently diameter expansion. Nevertheless, a chronic treatment with the AGEs breaker ALT711 restored high flow-mediated remodeling and, in part, endothelium-mediated dilation. The effect of diabetes on high-flow-mediated remodeling in depicted below.
More recently we have shown that estrogens preserve flow-mediated remodeling in old rats. Indeed, uterine arteries have been shown to undergo rapid and extensive remodeling during each cycle and during pregnancy. Estradiol also plays a key role in endothelial repair after injury. In addition, women are better protected from cardiovascular diseases, an advantage lost after menopause. Our recent findings show that the endothelial estrogen receptor alpha (ERa) plays a key role in flow-mediated outward remodeling of small resistance arteries and that this effect is lost after a prolonged ovariectomy. Indeed, maintaining flow-mediated outward remodeling in women could be essential for a better drug management. Antihypertensive treatments might be more efficient with fewer medications thus minimizing the side effects, which remain important with multi-drug therapies.
Recent studies have shown the presence of estrogen receptors in mitochondria and suggested that estradiol alters mitochondrial function. We have demonstrated that in vivo estrogen replacement at physiological doses leads to increased levels of key mitochondrial proteins, such as cytochrome C, mitochondrial transcription factors and antioxidant enzymes, in cerebral blood vessels of ovariectomized female rats.
