Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

3.2K
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...

Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

6.4K
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...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

5.0K
The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

mTOR Signaling and Cancer Progression

4.5K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

3.1K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Summary

Psoriasis dermal mesenchymal stem cells (DMSCs) overexpress epidermal growth factor-like repeats and discoidin I-like domains 3 (EDIL3). This protein promotes endothelial cell adhesion, migration, and tube formation, suggesting EDIL3 as a therapeutic target for psoriasis angiogenesis.

Area of Science:

  • Dermatology
  • Cell Biology
  • Angiogenesis Research

Background:

  • Psoriasis is associated with altered dermal mesenchymal stem cells (DMSCs).
  • DMSCs in psoriasis exhibit elevated expression of epidermal growth factor-like repeats and discoidin I-like domains 3 (EDIL3).
  • EDIL3 is known to interact with integrins and regulate angiogenesis.

Purpose of the Study:

  • To investigate the role of EDIL3 derived from Psoriatic DMSCs (P-DMSCs) in angiogenesis.
  • To determine the therapeutic potential of targeting EDIL3 in psoriasis.

Main Methods:

  • In vitro silencing of EDIL3 in P-DMSCs using interfering RNA.
  • Assessment of EDIL3 silencing efficacy via fluorescent tagging, qRT-PCR, and Western blotting.
  • In vitro co-culture system to evaluate EDIL3's effect on Human Umbilical Vein Endothelial Cells (HUVECs) angiogenesis.
  • In vivo study involving injection of EDIL3 recombinant protein into mouse psoriasis-like skin lesions and assessment of tube formation.

Main Results:

  • P-DMSCs demonstrated significantly enhanced adhesion, migration, and tube formation capacity of HUVECs compared to controls and EDIL3-silenced groups (P<0.05).
  • In vivo administration of EDIL3 recombinant protein markedly increased EDIL3-associated tube formation in mouse skin lesions (P<0.01).
  • EDIL3 promotes endothelial cell adhesion, migration, and tube formation, contributing to psoriasis angiogenesis.

Conclusions:

  • EDIL3 derived from P-DMSCs plays a significant role in promoting angiogenesis.
  • EDIL3 influences endothelial cell functions, implicating it in the pathogenesis of psoriasis.
  • EDIL3 represents a potential therapeutic target for psoriasis treatment due to its pro-angiogenic properties.
