Circular RNAs (circRNAs) are abnormal in many cancers and play key roles in carcinogenesis. This review covers circRNA biogenesis, their functions in cancer, and future research directions.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- Circular RNAs (circRNAs) are noncoding RNA molecules with a unique circular structure.
- Their biogenesis involves specific splicing mechanisms, including spliceosome-mediated and lariat-type pathways.
- Aberrant circRNA expression is frequently observed in various cancer types.
Purpose of the Study:
- To review the biogenesis of circRNAs, emphasizing regulation by RNA-binding proteins.
- To summarize recent findings on the molecular mechanisms and functions of circRNAs in cancer development.
- To discuss current challenges and future research avenues in the field.
Main Methods:
- Literature review of recent studies on circRNA biogenesis and function in cancer.
- Analysis of molecular mechanisms underlying circRNA roles in carcinogenesis.
- Synthesis of current knowledge and identification of open questions.
Main Results:
- CircRNAs are regulated during biogenesis by RNA-binding proteins.
- Specific circRNAs are implicated in the initiation and progression of various cancers.
- Diverse molecular mechanisms contribute to circRNA functions in cancer.
Conclusions:
- CircRNAs are significant players in cancer development.
- Understanding circRNA regulation and function is crucial for cancer research.
- Further investigation is needed to explore the therapeutic potential of circRNAs.
