Insights

Anticancer drug resistance is linked to complex tumor microenvironment communication. Exosomes, particularly exosomal microRNAs (miRNAs), are emerging as key regulators of tumor angiogenesis, offering new therapeutic targets.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Tumor angiogenesis is crucial for cancer growth and metastasis.
  • Current anti-angiogenesis therapies often fail due to complex signaling networks and compensatory pathways within the tumor microenvironment.
  • Previous research focused on soluble factors, overlooking other critical communication mechanisms.

Purpose of the Study:

  • To review the role of exosomes and their cargo, specifically exosomal microRNAs (miRNAs), in regulating tumor angiogenesis.
  • To highlight the significance of exosome-mediated signaling in overcoming therapeutic resistance.
  • To synthesize current knowledge on exosomal miRNAs as potential therapeutic targets for anti-angiogenesis strategies.

Main Methods:

  • Literature review and data collation from multiple research groups.
  • Analysis of studies investigating exosome biogenesis, cargo loading, and intercellular communication.
  • Focus on exosomal miRNA profiling and functional studies related to angiogenesis.

Main Results:

  • Exosomes play a significant role in intercellular communication within the tumor microenvironment.
  • Exosomal miRNAs are key mediators of tumor progression and angiogenesis.
  • Dysregulation of exosomal miRNA content contributes to therapeutic resistance by modulating signaling pathways.

Conclusions:

  • Exosomes represent a critical, yet often overlooked, component of tumor microenvironment signaling.
  • Exosomal miRNAs are potent regulators of angiogenesis and represent promising biomarkers and therapeutic targets.
  • Targeting exosomal miRNAs offers a novel strategy to overcome resistance to anti-angiogenesis cancer therapies.

The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

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...

lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

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...

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...

Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
