Abstrakt: Gastrin is a gastrointestinal peptide hormone that plays an important role in the progression of colorectal cancer (CRC). However, the molecular mechanism remains unclear. In this study, we identified gastrin-related circRNAs via high-throughput sequencing and selected circRNA_0017065 as the research focus. We further studied its specific role and molecular mechanism in the progression of CRC. Knockdown and overexpression of circRNA_0017065 were performed, and the biological function of circRNA_0017065 in CRC progression was studied via in vitro and in vivo functional experiments. The potential downstream target genes were subsequently identified via screening of databases and gene chip data. The expression of circRNA_0017065 in tumour tissues was significantly upregulated compared with that in adjacent normal tissues. In vitro and in vivo functional experiments revealed that the proliferation and migration of CRC cells were significantly suppressed after circRNA_0017065 knockdown, while apoptosis was promoted. After overexpression of circRNA_0017065, the proliferation and migration of CRC cells were significantly promoted, while apoptosis was inhibited. Mechanistic studies revealed that circRNA_0017065 can act as a sponge for miR-3174 and promote CRC progression via the miR-3174/RBFOX2 axis. In general, gastrin-related circRNA_0017065 plays a key role in the occurrence and development of CRC and is expected to be a potential molecular target for the treatment of CRC metastasis.
