Hsa_circRNA_0000518 facilitates breast cancer development via regulation of the miR-326/FGFR1 axis.

ABSTRACT:

Background

Breast cancer (BC) is a heterogeneous malignant tumor that threatens the health of women worldwide. Hsa_circRNA_0000518 (circ_0000518) has been revealed to be upregulated in BC tissues. However, the role and mechanism of circ_0000518 in BC are indistinct.

Methods

Quantitative real-time polymerase chain reaction (qRT-PCR) was implemented to detect the levels of circ_0000518, microRNA (miR)-326, and fibroblast growth factor receptor 1 (FGFR1) mRNA in BC tissues and cells. Cell counting kit-8 (CCK-8), colony formation, flow cytometry, and transwell assays were executed to estimate BC cell proliferation, cell cycle progression, apoptosis, migration, and invasion. The relationship between circ_0000518 or FGFR1 and miR-326 was verified by dual-luciferase reporter and/or
