Circular BANP, an upregulated circular RNA that modulates cell proliferation in colorectal cancer. Biomed Pharmacother. 2017 Jan 16;88:138-144 Authors: Zhu M, Xu Y, Chen Y, Yan F Abstract Circular RNAs (circRNAs) are recently identified as widespread and diverse endogenous noncoding RNAs that may harbor vital functions in human and animals. However, the role of circRNAs in the process of tumorigenesis and development of colorectal cancer (CRC) remains vague. Here we characterized the circRNA expression profile from three paired CRC cancerous and adjacent normal tissues by human circRNA array, and identified 136 significantly overexpressed circRNAs and 243 downregulated circRNAs in CRC cancerous tissues (>2-fold changes). We further validated one circRNA generated from Exon 5-11 of BANP gene, termed circ-BANP. In addition, RT-PCR result showed that circ-BANP was overexpressed in 35 CRC cancerous tissues. Knockdown of circ-BANP with siRNA significantly attenuate the proliferation of CRC cells. In summary, our findings demonstrated that dysregulated circ-BANP appears to have an important role in CRC cells and could serve as a prognostic and therapeutic marker for CRC.
