Insights

Natural products can modulate cancer cell functions by targeting exosomal microRNAs (miRNAs) involved in exosome processing. This study identifies key exosome-processing genes regulated by natural-product-modulated exosomal miRNAs for potential anticancer therapies.

Area of Science:

  • Oncology
  • Biochemistry
  • Molecular Biology

Background:

  • Cancer-derived exosomes play crucial roles in tumor progression, influencing proliferation, apoptosis, migration, and drug resistance.
  • While clinical drugs are known to modulate exosome functions, the impact of natural products on these processes is less understood.
  • Exosome biogenesis and secretion are regulated by specific exosome-processing genes, which can influence the overall function of cancer-derived exosomes.

Purpose of the Study:

  • To investigate the role of cancer-derived exosomal microRNAs (miRNAs) in regulating exosome processing.
  • To identify natural products that modulate these exosomal miRNAs and their processing targets.
  • To explore the potential of targeting exosome processing via natural products for anticancer strategies.

Main Methods:

  • Bioinformatic analysis using the miRDB database to predict exosome-processing genes modulated by exosomal miRNAs.
  • Literature review to identify natural products that influence exosomal miRNAs and cancer cell functions.
  • Integration of exosomal miRNA and exosome processing gene data to understand their interplay in cancer.

Main Results:

  • Identification of specific exosomal miRNAs that regulate exosome-processing genes in cancer.
  • Prediction of exosome-processing genes targeted by natural-product-modulated exosomal miRNAs.
  • Description of several natural drugs that modulate exosome processing and exosomal miRNAs, thereby affecting cancer cell functions.

Conclusions:

  • Exosome processing is a critical, yet often overlooked, mechanism in the context of exosomal miRNAs and natural product-based cancer therapy.
  • Targeting exosome-processing genes modulated by exosomal miRNAs offers a novel approach for natural product-driven anticancer treatments.
  • This review provides insights into the potential of exosomal miRNAs and their processing targets for developing effective natural product-based cancer therapies.

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...

Overview of Exosomes01:36

Overview of Exosomes

Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.
Stahl et al. discovered exosomes in 1983, but the exosomes were initially considered waste products released from 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...

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

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...
