Estrogen

Area of Science:

  • Cardiovascular Science
  • Endocrinology
  • Molecular Biology

Background:

  • Estrogens exert therapeutic effects via nuclear estrogen receptors (ERα, ERβ) and a novel G-protein-coupled estrogen receptor (GPER).
  • GPER mediates non-genomic signaling, including vasodilatory responses in blood vessels, but downstream pathways remain unclear.
  • Understanding estrogen receptor signaling is crucial for its therapeutic applications.

Purpose of the Study:

  • To review current knowledge on GPER's role in cardiovascular function.
  • To emphasize GPER's mediation of acute estrogen effects in the heart and blood vessels.
  • To explore GPER's potential in developing targeted therapies.

Main Methods:

  • Literature review of studies investigating GPER and cardiovascular effects.
  • Analysis of GPER signaling pathways in vascular tone, cell growth, apoptosis, endothelial function, and myocardial protection.
  • Synthesis of current understanding of GPER's contribution to estrogen's cardiovascular actions.

Main Results:

  • GPER activation influences vascular tone, cell growth, apoptosis, endothelial function, and myocardial protection.
  • GPER mediates rapid, non-genomic estrogen signaling in the cardiovascular system.
  • GPER's precise downstream signaling events require further elucidation.

Conclusions:

  • GPER plays a significant role in mediating acute estrogen effects on the cardiovascular system.
  • Understanding GPER function may resolve controversies surrounding estrogen and cardiovascular health.
  • Targeting GPER offers potential for developing cardiovascular therapies with reduced side effects.

G Protein-coupled Receptors01:15

G Protein-coupled Receptors

G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

Transducer Mechanism: Nuclear Receptors01:31

Transducer Mechanism: Nuclear Receptors

Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
Transducer Mechanism: Enzyme-Linked Receptors01:27

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:
Transducer Mechanism: G Protein–Coupled Receptors01:30

Transducer Mechanism: G Protein–Coupled Receptors

G Protein–Coupled Receptors (GPCRs) are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to various stimuli. GPCRs regulate critical physiological pathways and are excellent drug targets for treating diseases such as diabetes, cancer, obesity, depression, or Alzheimer's. Nearly 35% of approved drugs implement their therapeutic effects by selectively interacting with specific GPCRs.
GPCRs are also called heptahelical, 7TM, or...
GPCRs Regulate Adenylyl Cylase Activity01:09

GPCRs Regulate Adenylyl Cylase Activity

Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of cells.
