Circular RNA GLIS2 promotes colorectal cancer cell motility via activation of the NF-κB pathway.

ABSTRACT: Circular RNAs (circRNAs) are a newly discovered type of biological molecule that belongs to the noncoding RNA family. Abundant evidence has shown that circRNAs are involved in the progression of various cancers. However, the particular functions of circRNAs in colorectal cancer (CRC) remain elusive. In this study, we investigated the differentially expressed circRNAs in three pairs of cancer tissue and adjacent normal tissue of CRC. We revealed that circGLIS2 expression was higher in CRC tissue and cell lines. Gain-and-loss function assays showed that circGLIS2 was involved in the regulation of cell migration. Moreover, overexpressing circGLIS2 in CRC cells activated the NF-κB pathway and induced pro-inflammatory chemokine production, which evoked tumor-associated inflammation through recr
