Regulation of Angiogenesis and Blood Supply01:24

Regulation 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...
Lipid-derived Compounds in the Human Body01:31

Lipid-derived Compounds in the Human Body

Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various  biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin, delayed...
Oogenesis02:07

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
Hormonal Regulation of Blood Pressure01:17

Hormonal Regulation of Blood Pressure

Endocrinal or hormonal intervention in the cardiovascular system is predominantly exerted by the catecholamines - epinephrine and norepinephrine, as well as a slew of hormones that interact with renal function to modulate blood volume.
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...
Vascular Resistance01:20

Vascular Resistance

Vascular resistance is a critical concept in understanding blood flow dynamics in the circulatory system. It refers to the resistance that blood encounters as it flows through the blood vessels. This resistance is a key factor in determining blood pressure and cardiac workload.
The primary determinants of vascular resistance are vessel diameter, blood viscosity, and vessel length. Among these, vessel diameter plays the most significant role due to the fourth power relationship described by...
Overview of the Vascular System01:20

Overview of the Vascular System

The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and lymphatic systems. Typically, blood vessels can be categorized into three histological regions: tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a single layer of endothelial cells attached to the basal lamina. Underlying the basal lamina is a connective tissue layer and an elastic lamina that gives stability and...

Summary

Estrogens reduce vascular disease and protect against neovascular disorders like Kaposi's sarcoma through genomic and rapid non-genomic pathways. Research shows selective estrogen receptor expression on vascular cells, highlighting their protective potential.

Area of Science:

  • Endocrinology
  • Cardiovascular Biology
  • Oncology

Background:

  • Estrogens are linked to reduced atherosclerotic vascular disease and protection against neovascular disorders.
  • Estrogenic effects occur via both genomic and rapid non-genomic pathways.
  • Vascular cells express distinct estrogen receptor subtypes.

Purpose of the Study:

  • To review the vascular effects of estrogens, SERMs, and androgens.
  • To highlight the selective expression of estrogen receptors on human vascular cells.
  • To emphasize the protective role of estrogens in vascular health.

Main Methods:

  • Review of existing literature on estrogenic and androgenic effects on vascular cells.
  • Analysis of estrogen receptor subtype expression in different human vascular cell types.

  • Examination of genomic and non-genomic mechanisms of estrogen action.

    • Main Results:

    • Estrogens exert indirect antiatherosclerotic effects by modulating LDL levels and fibrinolysis.
    • Direct vascular actions include relaxation and vasodilation, inhibiting lesion progression.
    • Evidence supports selective expression of estrogen receptor subtypes (ERalpha, ERbeta) on various vascular cells.
    • Both genomic and rapid non-genomic actions contribute to estrogen's vascular effects.

    Conclusions:

    • Estrogens offer significant protective potential for the vasculature.
    • Understanding selective estrogen receptor modulation is key for therapeutic strategies.
    • Estrogens, SERMs, and androgens impact both normal and malignant vascular cells.
