ABSTRACT
Colon cancer (CC) is a common malignancy over the world and its morbidity and mortality significantly went up in China in recent years. Molecular functions in cancers have gradually been the pivot subject in cancer research. Neuroepithelial cell transforming 1 (NET1) was reported to contribute to prostate cancer and gastric cancer. Our study figured out that NET1 was overexpressed in CC cells. Then, loss-of-function assays revealed that NET1 facilitated CC cell proliferation and repressed CC cell apoptosis. Next, miR-338-3p was confirmed to target NET1. After that, we verified that circ_0017552 which originates from NET1 could positively modulate NET1 expression. Besides, circ_0017552 was a sponge of miR-338-3p. Rescue assays' results demonstrated that circ_0017552 could regulate CC cell proliferation and apoptosis through up-regulation of NET1. A transcription factor named Sp1 (SP1) was found to be present in circ_0017552. SP1 induced transcription of circ_0017552 to facilitate CC cell proliferation and inhibit CC cell apoptosis. In a word, SP1-induced circ_0017552 regulated CC cell proliferation and apoptosis through miR-338-3p/NET1 axis.
