Insights

Competing endogenous RNAs (ceRNAs) regulate gene expression by interacting with microRNAs (miRNAs). This RNA crosstalk is crucial in cancer, offering potential for diagnostics and treatment.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • Noncoding RNAs play a key role in post-transcriptional gene regulation.
  • RNA crosstalk and molecular interactions are implicated in various diseases, notably cancer.
  • Competing endogenous RNAs (ceRNAs) are a significant mechanism in this regulatory network.

Purpose of the Study:

  • To summarize the mechanisms of RNA interplay and deregulated transcription in cancer.
  • To highlight the role of ceRNAs in intracellular communication.
  • To underscore the significance of ceRNAs for cancer diagnostics and treatment.

Main Methods:

  • Review of current analytical approaches for studying ceRNAs.
  • Analysis of RNA crosstalk mechanisms.
  • Examination of deregulated transcription profiles in neoplasms.

Main Results:

  • ceRNAs competitively bind to microRNAs (miRNAs), influencing gene expression.
  • This interaction affects miRNA-induced degradation of target RNAs.
  • ceRNA networks are integral to cancer pathogenesis and progression.

Conclusions:

  • ceRNAs are vital in multilayered intracellular communication within cancer cells.
  • ceRNAs hold significant potential as diagnostic biomarkers and for prognosis evaluation.
  • Understanding ceRNA mechanisms offers new avenues for clinical cancer treatment.

Interactions Between Signaling Pathways01:19

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...

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...

Cancer-Critical Genes I: Proto-oncogenes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Mechanisms of Retrovirus-induced Cancers01:51

Mechanisms of Retrovirus-induced Cancers

Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...
