Abstract
Breast cancer (BC) is the most common malignant tumor in women. Recently, long noncoding RNAs (lncRNAs)
have been proposed as critical regulators in biological processes, including tumorigenesis. FOXC2-AS1, a single antisense oligonucleotide RNA transcribed from the negative strand of forkhead box protein C2 (FOXC2),
has been identified as an oncogene in osteosarcoma. In the present study, we investigated the prognosis value
and biological role of FOXC2-AS1 in BC. Our findings revealed that FOXC2-AS1 was significantly increased
in BC tissues and cell lines, and Kaplan–Meier survival analysis indicated that a high level of FOXC2-AS1
was associated with poor prognosis of BC patients. Loss of function revealed that silenced FOXC2-AS1 significantly suppressed the proliferation ability, and flow cytometric analysis illustrated the influence of FOXC2-
AS1 on cell cycle and apoptosis rate. Finally, we found that cyclin D1, cyclin D2, and cyclin D3 were all partly
positively modulated by FOXC2-AS1 in BC. Collectively, FOXC2-AS1 may serve as a promising prognostic
biomarker and therapeutic target for BC patients.
