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...
Veins of Head and Neck01:19

Veins of Head and Neck

The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...
The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
Mechanism of Angiogenesis01:10

Mechanism 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...

Area of Science:

  • Dermatology
  • Vascular Malformations

Background:

  • Unilateral nevoid telangiectasia (UNT) is a rare vascular anomaly.
  • It is characterized by the development of telangiectasias predominantly on one side of the body.
  • UNT is often associated with hormonal changes such as puberty, pregnancy, and oral contraceptive use, or conditions like alcoholic cirrhosis.

Observation:

  • A 30-year-old pregnant woman presented with a two-year history of asymptomatic telangiectasias on her right upper extremity.
  • The lesions, initially blanching, increased in number and redness with the onset of pregnancy.
  • The unilateral distribution and exacerbation during gestation were key diagnostic features.

Findings:

  • The patient was diagnosed with unilateral nevoid telangiectasia.
  • This diagnosis was based on the clinical presentation, distribution, and changes observed during pregnancy.
  • The case underscores that UNT can occur in otherwise healthy individuals without underlying systemic conditions.

Implications:

  • This case expands the understanding of unilateral nevoid telangiectasia presentation.
  • It emphasizes the importance of considering pregnancy as a trigger for the development or worsening of UNT.
  • Further research may elucidate the specific mechanisms linking hormonal fluctuations to the pathogenesis of UNT.
