Abstract:
CircHIPK3 is a type of endogenous circular RNA, which contains a covalently closed circular structure and cannot encode protein or polypeptide. CircHIPK3 is unusually expressed in varieties of tumors and plays dual roles of tumor promotion or tumor inhibition in tumorigenesis and development of tumors by serving as the sponge for miRNA in multiple tumors. Here, we reviewed the differential expression, the dual functions, the regulation mechanism, and the network in a variety of tumors as well as the potential value for the diagnosis and treatment of tumors, which are of great significance for our comprehensive understanding of the roles and mechanisms of circHIPK3 in tumors.
Insights
Circular HIPK3 (circHIPK3) RNA shows varied expression in tumors, acting as a tumor promoter or inhibitor. Understanding its roles is key for cancer diagnosis and treatment.
Area of Science:
- Molecular Biology
- Oncology
- Genetics
Background:
- Circular RNAs (circRNAs) are endogenous RNA molecules with a closed-loop structure.
- circHIPK3, a specific circRNA, is differentially expressed in various cancers.
- circHIPK3 lacks protein-coding potential but influences tumorigenesis.
Purpose of the Study:
- To review the differential expression of circHIPK3 in tumors.
- To elucidate the dual roles (promotion and inhibition) of circHIPK3 in tumorigenesis.
- To explore the regulatory mechanisms and network of circHIPK3 in cancer.
Main Methods:
- Literature review of studies on circHIPK3 in various cancers.
- Analysis of differential expression data.
- Examination of circHIPK3's function as a miRNA sponge.
Main Results:
- circHIPK3 exhibits altered expression patterns across different tumor types.
- circHIPK3 can act as both a tumor promoter and a tumor suppressor.
- circHIPK3 regulates gene expression by sponging microRNAs (miRNAs).
Conclusions:
- circHIPK3 plays a significant, context-dependent role in tumor development.
- circHIPK3 holds potential as a diagnostic biomarker and therapeutic target in oncology.
- Further research into circHIPK3 mechanisms is crucial for cancer therapy development.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
