Insights

Long noncoding RNAs (lncRNAs) within extracellular vesicles (sEV) interact with tumor-associated macrophages (TAMs) to influence cancer progression. Understanding these interactions offers new avenues for cancer immunotherapy and diagnosis.

Area of Science:

  • Oncology
  • Molecular Biology
  • Immunology

Background:

  • Long noncoding RNAs (lncRNAs) regulate cancer cell functions like growth and metastasis.
  • Tumor-associated macrophages (TAMs) are key players in the tumor microenvironment, impacting cancer progression.
  • Small extracellular vesicles (sEV) mediate intercellular communication, carrying molecules like lncRNAs between cancer cells and macrophages.

Purpose of the Study:

  • To review current knowledge on the interplay between sEV, lncRNAs, and TAMs in tumors.
  • To explore the role of these interactions in cancer onset and progression.
  • To provide insights into novel diagnostic and therapeutic strategies for cancer immunotherapy.

Main Methods:

  • Literature review of studies investigating lncRNAs, TAMs, and sEV in cancer.
  • Analysis of the mechanisms by which cancer cell and macrophage-derived sEV transport lncRNAs.
  • Synthesis of findings on the functional impact of these interactions on tumor progression.

Main Results:

  • lncRNAs carried by sEV can modulate TAM functions and influence the tumor microenvironment.
  • The dysregulation of lncRNAs, TAMs, and sEV is a common feature in various tumors.
  • These interactions are critical for cancer cell invasion, metastasis, and overall progression.

Conclusions:

  • The intricate relationship between sEV, lncRNAs, and TAMs presents promising targets for cancer immunotherapy.
  • Targeting these components could lead to the development of novel diagnostic biomarkers and therapeutic interventions for cancer.
  • Further research is needed to fully elucidate these complex interactions for clinical applications.

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...

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...

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...

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...
