The enzymes of catecholamine metabolism in experimental hypertension.
Loučková, Anna ; Kuneš, Jaroslav (advisor) ; Klevstigová, Martina (referee)
Catecholamines dopamine, norepinephrine and epinephrine are significantly involved in regulation of blood pressure. The most important enzymes participating in their metabolism are tyrosin hydroxylase, DOPA dekarboxylase, dopamine β-hydroxylase and phenylethanolamine N-methyltransferase. This thesis summarizes current knowledge about these enzymes, focusing on their role in the development of essential hypertension. Experimental models are often used in the study of hypertension because of their practical and ethic reasons. Most findings were obtained in spontaneously hypertensive rats, due to their similarity to human essential hypertension. Metabolism of catecholamines in spontaneously hypertensive rat differs in many aspects from that of normotensive controls. The primary cause of this type of hypertension has not yet been distinguished from compensatory responses. However, prevention or slow-down the disease-development process can be achieved by various interventions. This information may help to identify new treatments for human hypertension.
