Abstract:
Several lines of evidence suggest that hypertension and angiogenesis may be related phenomena but a functional link remains elusive. Here, we propose that the renin-angiotensin system (RAS), in addition to its central role in arterial hypertension, also regulates blood vessel formation during normal development and cancer. This mechanistic hypothesis is based on reports of biochemical, genetic, clinical, and epidemiologic data reviewed herein. Species differences between the RAS of rodents and humans likely account for why such a fundamental role in angiogenesis went unrecognized for so long. If proven correct, this hypothesis carries many implications for the medical practices of cardiology, oncology, and neonatology.

Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...
