Insights

The G protein-coupled oestrogen receptor (GPER) plays a key role in health and disease. This review covers a decade of GPER research, highlighting its therapeutic potential.

Area of Science:

  • Endocrinology and Molecular Biology

Background:

  • Oestrogens and their receptors are crucial for physiology and disease, including cardiovascular, metabolic, neurological conditions, and hormone-sensitive cancers.
  • Oestrogen receptors include oestrogen receptor-α (ERα), oestrogen receptor-β (ERβ), and the 7-transmembrane G protein-coupled oestrogen receptor (GPER).
  • GPER mediates rapid signaling and transcriptional regulation, and its activity is modulated by oestrogen mimetics and drugs like SERMs and SERDs.

Purpose of the Study:

  • To summarize advancements in GPER research over the past decade, following the 2011 review.
  • To review molecular, cellular, and pharmacological aspects of GPER signaling and function.
  • To explore GPER's contribution to physiology, health, and disease, and its potential as a therapeutic target and prognostic indicator.

Main Methods:

  • Comprehensive literature review of GPER research published in the last decade.
  • Analysis of molecular, cellular, and pharmacological data related to GPER.
  • Examination of clinical trial data and drug repurposing opportunities for GPER.

Main Results:

  • GPER research has significantly progressed over the last decade.
  • GPER is implicated in various physiological and pathological processes.
  • The potential of GPER as a therapeutic target and prognostic marker is increasingly recognized.

Conclusions:

  • GPER is a significant target for therapeutic intervention and disease prognosis.
  • The review discusses the first clinical trial of a GPER-selective drug and drug repurposing strategies.
  • Further research into GPER signaling and pharmacology holds promise for novel treatments.

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,...

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...

G-protein Coupled Receptors01:21

G-protein Coupled Receptors

G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

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...

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:

GPCR Desensitization01:12

GPCR Desensitization

G protein-coupled receptor (GPCR) signaling plays a crucial role in cell functioning. GPCR desensitization is an equally essential process. It allows cells to respond to changing environments and regain sensitivity to new stimuli while preventing unnecessary stimulation when no longer needed. Prolonged exposure to stimuli leads to GPCR desensitization. It involves blocking the receptors from binding and activating additional G proteins. This inhibits activation of downstream effectors, thereby...
