Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

3.9K
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...

lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

10.1K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

7.5K
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...

mTOR Signaling and Cancer Progression

5.0K
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...

MicroRNAs

4.2K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Area of Science:

  • Molecular Biology
  • Oncology
  • Biochemistry

Background:

  • Solid tumor growth beyond 2mm necessitates angiogenesis, the formation of new blood vessels.
  • Tumor angiogenesis is regulated by a balance of pro-angiogenic (e.g., VEGF) and anti-angiogenic factors.
  • Matrix metalloproteinases (MMPs), tissue inhibitors of metalloproteinases (TIMPs), and oncogenes also influence tumor angiogenesis.

Purpose of the Study:

  • To explore the role of noncoding RNAs (ncRNAs), particularly microRNAs, in regulating tumor angiogenesis.
  • To elucidate the molecular mechanisms by which ncRNAs modulate angiogenic factors and signaling pathways.
  • To highlight the therapeutic potential of targeting ncRNAs for cancer treatment.

Main Methods:

  • Review of existing literature on ncRNAs, microRNAs, and long noncoding RNAs (lncRNAs) in angiogenesis.
  • Analysis of molecular mechanisms involving ncRNA targeting of angiogenic factors and signaling pathways.
  • Discussion of the functional roles of characterized lncRNAs in malignant diseases and angiogenesis.

Main Results:

  • MicroRNAs directly regulate angiogenesis by targeting key angiogenic factors and signaling molecules.
  • Accumulating evidence indicates microRNAs play significant roles in oncogenesis and modulate proliferation, apoptosis, and differentiation.
  • While the mechanisms of most lncRNAs remain unknown, some characterized lncRNAs demonstrate important roles in cancer.

Conclusions:

  • MicroRNAs are critical regulators of tumor angiogenesis with significant therapeutic potential for cancer patients.
  • Further research into the mechanisms of lncRNAs in angiogenesis is warranted due to their emerging role in malignant diseases.
  • Targeting ncRNAs presents a promising avenue for developing novel anti-cancer therapies.
