Abstract:
Circular RNAs (circRNAs) has been found to play an important role in the regulation of multiple diseases, and participate in cancer development. However, the role of circRNA in malignant melanoma has not been reported. In this study, human circRNA microarray was used to screen the dysregulated circRNA in melanoma. We found that circRNA_0084043 was significantly up-regulated in melanoma tissue, and the result was replicated in a larger sample size. High circRNA_0084043 expression was an independent risk factor of overall survival in melanoma patients. circRNA_0084043 promotes melanoma cell proliferation, invasion and migration. Bioinformatics and luciferase reporter assays confirmed that circRNA_0084043 directly binds to miR-153-3p, and Snail is directly targeted by miR-153-3p. We also demonstrated that circRNA_0084043 may act as the sponge of miR-153-3p to up-regulate Snail expression, and consequently function as an oncogene in melanoma. Overall, this result elucidates a new mechanism for circRNA_0084043 in melanoma development and provides a potential therapeutic target for melanoma patients.
Insights
Circular RNAs (circRNAs) are involved in diseases. This study identifies circRNA_0084043 as a key oncogene in malignant melanoma, promoting tumor growth and progression.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:

Perpendicular-Axis Theorem
Consider a circular disc of mass M and radius R lying along an x-y plane. The origin lies at the center of the disc, and the z-axis is perpendicular to the disc's plane. All three axes coincide at the disc's center. The moment of inertia of this...

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...
