Summary
Gonadotropins, including hCG, LH, and FSH, regulate reproductive functions and act as tissue-specific angiogenic factors. Their interactions with angiogenic factors are crucial for reproductive health but can be disturbed in pathological conditions.
Area of Science:
- Reproductive endocrinology
- Angiogenesis research
- Vascular biology
Background:
- Gonadotropins (hCG, LH, FSH) are key reproductive hormones.
- Emerging evidence suggests gonadotropins influence reproductive organ vascularization.
- Thyroid-stimulating hormone (TSH) shares structural similarities and gonadal actions.
Purpose of the Study:
- To review the regulatory role of gonadotropins in vasculo- and angiogenesis.
- To examine the influence of gonadotropins on angiogenic factors (VEGF, angiopoietins, etc.).
- To discuss the involvement of gonadotropins and TSH in reproductive health and disease.
Main Methods:
- Literature review of current research on gonadotropins and angiogenesis.
- Analysis of studies investigating gonadotropin effects on endothelial cells and angiogenic factors.
- Examination of pathological conditions linked to disturbed gonadotropin-angiogenic factor interactions.
Main Results:
- Gonadotropins modulate VEGF, its receptors, angiopoietins, and other angiogenic factors.
- Gonadotropins may exert direct effects on endothelial cells.
- These hormones act as tissue-specific angiogenic factors, vital for reproductive organ vascular supply.
Conclusions:
- Gonadotropins are critical regulators of vasculo- and angiogenesis in reproductive tissues.
- Dysregulation of gonadotropin-angiogenic factor interactions is implicated in reproductive pathologies.
- TSH also exhibits significant gonadal actions, warranting further investigation.

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...
01:24Gonadal and Placental Hormones
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...

01:28Role of Hematopoietic Growth Factors
Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.

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...
01:16TGF - β Signaling Pathway
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
01:30General Transcription Factors
Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...
