Abstract:
The competing endogenous RNA (ceRNA) hypothesis was introduced. There is a new hypothesis about mRNA, pseudogene transcripts and long noncoding RNAs (lncRNAs) regulate each other's expression by using microRNA response elements (MREs) to compete for the binding of microMRA (miRNA). To date, numbers lines of evidence in bioinformatics, cell biology and animal models from several famous laboratories have supported the ceRNA hypothesis. We also trace the history of the concept of ceRNA and discuss the molecular mechanisms of ceRNAs in cancers and their possible applications. In this review, we try to give readers a concise and reliable illustration on the mechanism, research approaches, and perspective of ceRNA in cancer.
Insights
The competing endogenous RNA (ceRNA) hypothesis explains how RNAs like mRNA, pseudogenes, and lncRNAs regulate each other. This mechanism, involving microRNA response elements, is crucial in cancer research.
Area of Science:
- Molecular Biology
- Genetics
- Cancer Research
Background:
- The competing endogenous RNA (ceRNA) hypothesis proposes a novel regulatory network.
- It involves interactions between messenger RNAs (mRNAs), pseudogene transcripts, and long noncoding RNAs (lncRNAs).
- These interactions occur via microRNA response elements (MREs), mediating competition for microRNA (miRNA) binding.
Purpose of the Study:
- To review the historical development of the ceRNA hypothesis.
- To elucidate the molecular mechanisms of ceRNAs in cancer.
- To discuss the potential applications of ceRNAs in cancer research and therapy.
Main Methods:
- Literature review and synthesis of existing evidence.
- Analysis of bioinformatics, cell biology, and animal model data.
- Discussion of historical context and molecular mechanisms.
Main Results:
- Substantial evidence from multiple research fields supports the ceRNA hypothesis.
- ceRNAs play significant roles in the molecular pathology of various cancers.
- Understanding ceRNA networks offers potential therapeutic strategies.
Conclusions:
- The ceRNA hypothesis provides a framework for understanding complex gene regulation.
- ceRNAs are implicated in cancer development and progression.
- Further research into ceRNA mechanisms and applications is warranted for cancer treatment.
