Hsa_circ_0001925 promotes malignant progression in triple-negative breast cancer via miR-1299/YY1 axis.

ABSTRACT:

Background

Circular RNAs (circRNAs) are related to the pathogenesis and progression of triple-negative breast cancer (TNBC). The aim of this study was to investigate the role and mechanism of hsa_circ_0001925 in TNBC progression.

Methods

Hsa_circ_0001925, microRNA (miR)-1299 and Yin Yang 1 (YY1) levels were examined in TNBC via reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot. Cell counting kit-8 (CCK-8), colony formation, 5-ethynyl-2'-deoxyuridine (EdU) staining, flow cytometry, wound healing assay and tube formation assay were conducted to estimate the effects of hsa_circ_0001925 on malignant phenotypes of TNBC tumors. Several protein levels were measured with western blot. The regulatory relationship between miR-1299 and hsa_circ_000
