Insights

Dietary flavonols show potential in breast cancer therapy by modulating angiogenesis-regulating microRNAs (angiomiRs). Further research is needed to validate these findings for clinical applications in precision oncology.

Area of Science:

  • Oncology
  • Molecular Biology
  • Nutritional Science

Background:

  • Angiogenesis is crucial for breast cancer growth and metastasis.
  • Current therapies targeting vascular endothelial growth factor (VEGF) have limited efficacy due to resistance.
  • Angiogenesis-regulating microRNAs (angiomiRs) are key regulators of tumor vascular plasticity and immune evasion.

Purpose of the Study:

  • To review the mechanistic links between dietary flavonols and angiomiR-mediated regulation in breast cancer.
  • To evaluate the therapeutic potential of flavonols in overcoming resistance to anti-angiogenic therapies.
  • To identify gaps in current research for future translational studies.

Main Methods:

  • A narrative review of studies published between 2010-2026.
  • Searches conducted across Google Scholar, PubMed, Scopus, and Web of Science.
  • Synthesis of mechanistic and translational findings on flavonols, angiomiRs, and breast cancer angiogenesis.

Main Results:

  • Flavonols (kaempferol, myricetin, quercetin) exhibit anti-angiogenic activity in preclinical models.
  • Flavonols may influence angiogenesis directly by inhibiting signaling pathways and indirectly via non-coding RNA modulation.
  • Evidence suggests flavonols can impact hypoxia signaling, endothelial activation, and vascular normalization through angiomiR networks.

Conclusions:

  • Flavonol modulation of angiomiRs presents a promising, mechanistically supported strategy against breast cancer angiogenesis.
  • Current evidence is largely preclinical, highlighting a need for experimental validation of specific flavonol-angiomiR interactions.
  • Further translational research is essential to clarify the therapeutic relevance of flavonols in precision oncology for breast cancer.

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...
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...
MicroRNAs01:22

MicroRNAs

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...
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...
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...
