Summary
Prostanoids significantly impact circulatory systems, especially in fetuses, regulating blood flow in the brain, eyes, and ductus arteriosus. Research highlights the crucial role of prostanoid receptors in fetal vascular development and function.
Area of Science:
- Cardiovascular Physiology
- Developmental Biology
- Pharmacology
Background:
- Prostanoids are potent signaling molecules affecting vascular beds.
- Their role in perinatal circulation, including brain, eyes, and ductus arteriosus, is critical.
- Prostanoid actions are mediated by G protein-coupled receptors.
Purpose of the Study:
- To review prostanoid receptors and their implications in developing subjects.
- To highlight the role of prostanoid receptors in perinatal vascular physiology.
- To discuss recent advances in understanding prostanoid receptor biology.
Main Methods:
- Review of pharmacological characterization of prostanoid receptors.
- Analysis of data from cloned receptors and gene-disrupted animal models.
- Investigation of prostanoid receptor involvement in developing vasculature.
Main Results:
- Prostanoid receptors play a key role in autoregulation of blood flow in fetal brain and eyes.
- Prostaglandins are dominant regulators of ductus arteriosus tone.
- Ontogenic changes in prostanoid receptor expression occur during development, some due to homologous regulation.
Conclusions:
- Prostanoid receptors are vital for perinatal vascular development and function.
- Understanding these receptors offers insights into fetal circulatory regulation.
- Functional perinuclear prostaglandin E2 receptors have been identified, expanding knowledge of prostanoid signaling.

01:10Mechanism of Angiogenesis
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
01:24Regulation 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 hydroxylase and factor...
01:27Transducer 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.

01:31Adrenergic Receptors: ɑ Subtype
Adrenoceptors are classified into α and ꞵ classes based on their potencies to catecholamine agonists. α-adrenoceptors show the following order of catecholamine potency:
Adrenaline ≥ Noradrenaline >> Isoprenaline
α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase C—inositol-1,4,5-trisphosphate...

01:26Adrenergic Receptors: β Subtype
β-adrenoceptors have varied sensitivities towards adrenaline, noradrenaline, and isoprenaline. The order of agonist potency is as follows:
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.
β1-adrenoceptors: β1-adrenoceptors have equal affinities for...

01:23Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists
Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...
