Abstract:
A Disintegrin and Metalloprotease 17 (ADAM17), also called tumor necrosis factor-ɑ (TNF-ɑ) convertase (TACE), is a well-known protease involved in the sheddase of growth factors, chemokines and cytokines. ADAM17 is also enrolled in hypertension, especially by shedding of angiotensin converting enzyme type 2 (ACE2) leading to impairment of angiotensin 1-7 [Ang-(1-7)] production and injury in vasodilation, induction of renal damage and cardiac hypertrophy. Activation of Mas receptor (MasR) by binding of Ang-(1-7) induces an increase in the nitric oxide (NO) gaseous molecule, which is an essential factor of vascular homeostasis and blood pressure control. On the other hand, TNF-ɑ has demonstrated to stimulate a decrease in nitric oxide bioavailability, triggering a disrupt in endothelium-dependent vasorelaxation. In spite of the previous studies, little knowledge is available about the involvement of the metalloprotease 17 and the NO pathways. Here we will provide an overview of the role of ADAM17 and Its mechanisms implicated with the NO formation.
Insights
Disintegrin and Metalloprotease 17 (ADAM17) impacts hypertension by affecting angiotensin converting enzyme type 2 (ACE2) and nitric oxide (NO) pathways. This overview explores ADAM17
Area of Science:
- Biochemistry
- Cardiovascular Physiology
- Molecular Biology
Background:
- A Disintegrin and Metalloprotease 17 (ADAM17), also known as tumor necrosis factor-ɑ (TNF-ɑ) convertase (TACE), is a protease regulating growth factors, chemokines, and cytokines.
- ADAM17 plays a role in hypertension, particularly through the shedding of angiotensin converting enzyme type 2 (ACE2), which impairs angiotensin 1-7 [Ang-(1-7)] production, leading to vasodilation issues, renal damage, and cardiac hypertrophy.
Purpose of the Study:
- To provide an overview of the role of ADAM17 in the context of nitric oxide (NO) pathways.
- To elucidate the mechanisms by which ADAM17 influences NO formation and bioavailability.
Main Methods:
- Literature review focusing on ADAM17, ACE2, Ang-(1-7), Mas receptor (MasR), and nitric oxide (NO) signaling.
- Analysis of existing studies on the interplay between ADAM17 activity and endothelial function.
Main Results:
- ADAM17-mediated shedding of ACE2 disrupts the Ang-(1-7)/MasR/NO pathway, contributing to hypertension.
- Tumor necrosis factor-ɑ (TNF-ɑ), influenced by ADAM17, can decrease NO bioavailability, impairing vasorelaxation.
Conclusions:
- ADAM17 is a key player in cardiovascular regulation through its influence on NO pathways.
- Understanding ADAM17's role in NO formation is crucial for developing novel therapeutic strategies for hypertension and related cardiovascular diseases.

Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....
