Insights

Selective activation of the G-protein-coupled estrogen receptor (GPER) in coronary arteries shows promise for treating coronary heart disease (CHD). This approach may increase blood flow and reduce disease consequences while avoiding estrogen therapy side effects.

Area of Science:

  • Cardiovascular Biology
  • Endocrinology
  • Pharmacology

Background:

  • Coronary heart disease (CHD) is a leading cause of mortality.
  • Estrogen therapy for CHD has potential benefits but significant side effects and risks.
  • Estrogen therapy may be detrimental to cardiovascular health in postmenopausal women.

Purpose of the Study:

  • To review the current understanding of G-protein-coupled estrogen receptor (GPER) activation in coronary arteries.
  • To explore the potential of selective GPER activation as a therapeutic strategy for CHD.
  • To discuss the signaling mechanisms involved in GPER activation within coronary arteries.

Main Methods:

  • Review of existing scientific literature on GPER expression and function in coronary arteries.
  • Analysis of studies investigating the effects of GPER agonists on coronary vasodilation.
  • Examination of research on GPER's role in coronary smooth muscle cell proliferation and migration.

Main Results:

  • G-protein-coupled estrogen receptor (GPER) is expressed in coronary endothelium and smooth muscle.
  • GPER activation leads to coronary artery dilation.
  • GPER activation inhibits coronary smooth muscle cell proliferation and migration.

Conclusions:

  • Selective GPER activation offers a potential therapeutic avenue for treating coronary heart disease (CHD).
  • Targeting GPER may increase coronary blood flow and mitigate atherosclerotic disease progression.
  • Understanding GPER signaling could lead to novel CHD therapies with improved safety profiles compared to traditional estrogen therapy.

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: 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.

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,...

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...
