Insights

MicroRNAs (miRNAs) are crucial in cancer gene regulation and can be detected in body fluids. Exosomal miRNAs mediate cancer cell communication, influencing the tumor microenvironment and metastasis.

Area of Science:

  • Molecular Biology
  • Oncology
  • Biochemistry

Background:

  • MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression.
  • Aberrant miRNA expression is a hallmark of human cancers.
  • Circulating miRNAs in body fluids show potential as cancer biomarkers.

Purpose of the Study:

  • To review recent advances in understanding the role of exosomal miRNAs in cancer.
  • To highlight exosomal miRNAs as mediators of cancer cell-to-cell communication.
  • To explore their contribution to the tumor microenvironment and metastasis.

Main Methods:

  • Literature review of recent research on exosomal miRNAs in cancer.
  • Analysis of studies investigating miRNA-mediated cell communication.
  • Synthesis of findings on the role of exosomal miRNAs in tumorigenesis and metastasis.

Main Results:

  • Exosomal miRNAs are secreted by tumor cells within microvesicles.
  • These miRNAs act as signaling molecules in intercellular communication.
  • They play a significant role in establishing and maintaining the tumor microenvironment and metastatic niche.

Conclusions:

  • Exosomal miRNAs are key mediators of cancer cell communication.
  • Their aberrant expression and function contribute to cancer progression.
  • Further research into exosomal miRNAs holds promise for novel diagnostic and therapeutic strategies.

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 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.

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...

Autocrine Signaling01:01

Autocrine Signaling

Autocrine signaling is one of the many signaling mechanisms that function inside multicellular organisms to carry out intercellular communication. In this type of signaling mechanism, the same cell that secretes an extracellular signaling molecule also expresses the receptors to bind and respond to that signaling molecule.

Under normal physiological conditions, autocrine signaling is essential for maintaining homeostasis. This process is well characterized in...
