Insights

MicroRNAs regulate gene expression and are key to cancer metastasis. This study examines microRNA roles in metastasis and evaluates microRNA-based therapies for advanced cancers.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Cancer metastasis is the leading cause of cancer mortality.
  • Metastasis involves significant genetic alterations and gene expression changes in cancer cells.
  • MicroRNAs (miRNAs) are small non-coding RNAs crucial for gene expression regulation.

Purpose of the Study:

  • To investigate the role of microRNAs in cancer metastasis.
  • To analyze microRNA dysregulation in metastatic cancer cells.
  • To review microRNA-based strategies for targeting metastasis.

Main Methods:

  • Dissection of the metastatic process step-by-step.
  • Examination of microRNA involvement at each metastatic stage.
  • Review of pre-clinical models and clinical trials using miRNA-based therapies.

Main Results:

  • MicroRNAs are significantly dysregulated in metastatic cancer cells.
  • Specific microRNAs are implicated at various steps of the metastatic cascade.
  • Pre-clinical studies show promise for miRNA-based anti-metastasis strategies.

Conclusions:

  • MicroRNAs are critical determinants of cancer metastasis.
  • Targeting microRNA dysregulation offers a potential therapeutic avenue for metastatic cancers.
  • Clinical trials are exploring microRNA-based therapies for advanced and metastatic tumors.

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...

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...

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...

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...

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...
