Insights

The NEDD4 family of E3 ubiquitin ligases plays a crucial role in cardiovascular disease by modifying protein substrates. This review highlights their involvement and potential as therapeutic targets for heart conditions.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Cardiovascular Research

Background:

  • Protein ubiquitination is a key post-translational modification influencing protein stability and function.
  • E3 ubiquitin ligases, specifically the NEDD4 family, are implicated in various cellular processes.
  • Dysregulation of ubiquitination pathways is increasingly linked to cardiovascular diseases.

Purpose of the Study:

  • To comprehensively review the role of NEDD4 family proteins in cardiovascular disease.
  • To provide insights into the prevention and treatment strategies for cardiovascular conditions targeting NEDD4.
  • To identify potential future research directions for understanding NEDD4's cardiovascular functions.

Main Methods:

  • Literature review of recent studies on NEDD4 family members and cardiovascular disease.
  • Analysis of substrate proteins recognized by NEDD4 family members via their WW domains.
  • Discussion of potential experimental approaches like transgenic animal models and gene silencing.

Main Results:

  • The NEDD4 family recognizes diverse substrates (e.g., PTEN, ENaC, Nav1.5) involved in cardiovascular regulation.
  • NEDD4 family proteins are implicated in a wide spectrum of cardiovascular diseases, including hypertension, heart failure, and atherosclerosis.
  • This review consolidates current knowledge on NEDD4's multifaceted roles in the cardiovascular system.

Conclusions:

  • NEDD4 family proteins are critical regulators in cardiovascular health and disease.
  • Targeting NEDD4 ubiquitination pathways offers potential for novel cardiovascular therapies.
  • Further research, including target identification and clinical quantification, is warranted to fully elucidate NEDD4's significance.

Regulation of the Cardiovascular System01:27

Regulation of the Cardiovascular System

The regulation of the cardiovascular system allows the body to adapt to various demands and maintain homeostasis.
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...

Regulated Protein Degradation02:58

Regulated Protein Degradation

It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

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...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
