Insights

MicroRNAs (miRNAs) regulate tumor angiogenesis, a key process in cancer growth and metastasis. This study explores miRNA-controlled pathways and delivery methods for anti-angiogenic cancer therapies.

Area of Science:

  • Molecular Biology
  • Cancer Research
  • Biochemistry

Background:

  • Tumor development and metastasis heavily rely on angiogenesis, the formation of new blood vessels.
  • MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression and are implicated in various biological processes, including cancer.
  • Endothelial cell (EC) activity is crucial for angiogenesis and is modulated by miRNAs through diverse signaling pathways.

Purpose of the Study:

  • To elucidate miRNA-regulated signaling pathways involved in tumor angiogenesis.
  • To highlight the response to anti-angiogenic therapy.
  • To review miRNA delivery methods for inhibiting angiogenesis.

Main Methods:

  • Review of existing literature on miRNA function in angiogenesis.
  • Analysis of miRNA-regulated signaling pathways in cancer.
  • Examination of in vitro and in vivo studies on miRNA-based anti-angiogenic strategies.

Main Results:

  • MicroRNAs can act as oncogenes or tumor suppressors, influencing angiogenic signaling.
  • Tumor-derived extracellular vesicles can deliver miRNAs to ECs, impacting angiogenesis.
  • MiRNAs show significant potential as therapeutic agents to inhibit tumor angiogenesis.

Conclusions:

  • Understanding miRNA-regulated pathways is crucial for developing effective anti-angiogenic cancer therapies.
  • Targeted delivery of miRNAs offers a promising strategy for cancer treatment by inhibiting angiogenesis.
  • Further research into miRNA mechanisms and delivery systems can advance cancer therapy.

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...

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...

Non-Canonical Wnt Signaling Pathways01:41

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Canonical Wnt Signaling Pathway02:54

Canonical Wnt Signaling Pathway

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...
