MicroRNA‑934 promotes colorectal cancer cell proliferation by directly targeting Dickkopf‑related protein 2

Abstract

Increasing evidence demonstrates that dysregulation of microRNAs (miRNAs/miRs) is implicated in the development of colorectal cancer. However, the biological functions of several differentially expressed miRNAs remain unknown. In the present study, a bioinformatic analysis of a previously published microarray data and reverse transcription-quantitative PCR analysis demonstrated that miR-934 expression was upregulated in colorectal cancer samples collected from patients. Mechanistically, Dickkopf-related protein 2 (DDK2) was identified as a novel target gene of miR-934 in colorectal cancer cells. Knockdown of DDK2 reversed the inactivation of Wnt signaling pathway induced using miR-934 inhibitor in colorectal cancer cells. In addition, DDK2 silencing reversed miR-934 inhibitor-induced cell proliferation inhibition and elevation of cell apoptosis. The results demonstrated that DDK2 mRNA expression was negatively associated with miR-934 expression in colorectal tumors. Collectively, the results of the present study demonstrated that the miR-934/DDK2 axis regulated colorectal cancer cell proliferation, suggesting that miR-934 may be a biomarker for patients with colorectal cancer.

“…Of these, SALL1 can interact with β-catenin and synergistically activate a reporter construct that responds to Wnt signaling by recruiting remodeling factors to heterochromatin ( Zhu et al., 2019 ). In this study, DEGs related to the ZF structure and Wnt/β-catenin signaling pathway were also screened, such as ovo like ZF 2 ( OVOL2 ) and pleomorphic adenoma gene 1 ( PLAG1 ), Wnt family member 5A ( Wnt5A ), Dickkopf Wnt signaling pathway inhibitor 3 ( Liu et al., 2021 ), and frizzled related protein ( Tuerlings et al., 2022 ).…”
