Insights

Retinoid X receptor (RXR) plays a crucial role in liver health by regulating metabolism and bile acid homeostasis. Understanding RXR heterodimers offers potential as a novel drug target for liver diseases.

Area of Science:

  • Hepatology
  • Molecular Endocrinology
  • Biochemistry

Background:

  • Nuclear receptors (NRs) are vital regulators of liver physiology and pathology.
  • Retinoid X receptor (RXR) is a unique NR that independently signals and forms heterodimers with other NRs.

Purpose of the Study:

  • To elucidate the structural features and functions of RXR and its heterodimers.
  • To highlight the role of RXR heterodimers in liver physiological and pathological processes.
  • To provide a theoretical basis for RXR as a pharmacological target in liver diseases.

Main Methods:

  • Review of existing literature on RXR structure and function.
  • Analysis of RXR heterodimer involvement in hepatic metabolic pathways.
  • Focus on RXR's role in liver homeostasis and disease.

Main Results:

  • RXR is integral to hepatic glucose, lipid, and cholesterol metabolism.
  • RXR heterodimers are key in bile acid homeostasis and hepatic fibrosis.
  • Specific RXR dimer activation presents potential therapeutic strategies.

Conclusions:

  • RXR heterodimers are critical regulators of diverse liver functions.
  • Targeting specific RXR heterodimers may offer new therapeutic avenues for liver conditions.
  • Further research into RXR's role can advance liver disease pharmacotherapy.

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:

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...

Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

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:
