Summary
This study reviews angiotensin converting enzyme (ACE) in the venoms of two Brazilian fish, Thalassophryne nattereri and Scorpaena plumieri. Their specific roles in venom function remain largely unknown.
Area of Science:
- Biochemistry
- Toxicology
- Marine Biology
Background:
- Animal venoms contain diverse bioactive molecules investigated for pharmacological potential.
- Thalassophryne nattereri and Scorpaena plumieri are venomous fish from Brazil causing significant injuries.
- Their venoms induce severe inflammatory responses and tissue damage in humans.
Purpose of the Study:
- To provide an overview of the current knowledge on angiotensin converting enzyme (ACE) in the venoms of Thalassophryne nattereri and Scorpaena plumieri.
- To explore the presence and potential function of ACE in these fish venoms.
- To highlight the significance of studying venom components for understanding biological mechanisms and potential applications.
Main Methods:
- Literature review of studies on Thalassophryne nattereri and Scorpaena plumieri venoms.
- Analysis of reported biochemical activities of venom components, specifically ACE.
- Comparison of ACE presence and characteristics across different venomous species.
Main Results:
- Angiotensin converting enzyme (ACE) activity has been recently identified in the venoms of Thalassophryne nattereri and Scorpaena plumieri.
- ACE plays a crucial role in regulating blood pressure and electrolyte balance in physiological systems.
- The specific function and contribution of ACE to the overall toxicity and effects of these fish venoms are currently unknown.
Conclusions:
- The presence of ACE in Thalassophryne nattereri and Scorpaena plumieri venoms is a significant finding.
- Further research is needed to elucidate the precise role of venom ACE in envenomation.
- Understanding venom ACE may reveal novel insights into venom evolution and potential therapeutic targets.

2.7K
Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...

1.7K
The renin-angiotensin-aldosterone system (RAAS) is an intricate physiological pathway involving numerous enzymes and hormones, including renin, angiotensin-converting enzyme (ACE), angiotensin I and II, and aldosterone. Imbalances within this system increase the production of angiotensin II and aldosterone. Increased angiotensin II levels promote vasoconstriction and blood pressure elevation. Concurrently, higher aldosterone levels stimulate sodium and water reabsorption in the kidneys,...

01:30Antihypertensive Drugs: Angiotensin II Receptor Blockers
2.9K
In the renin-angiotensin-aldosterone system, a hormone called angiotensin II plays a crucial role. It binds to the AT1 receptors in vascular smooth muscles coupled with Gq proteins. The activation of these receptors activates an enzyme called phospholipase C, which releases two molecules: inositol trisphosphate and diacylglycerol. These molecules cause a chain reaction that leads to the phosphorylation of myosin light chains and promotes interaction between actin and myosin, leading to smooth...

1.3K
The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme...

3.8K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...
