Abstract
Breast cancer is the most common high-grade malignancy in women. The lack of therapeutic targets has limited the treatment of breast cancer. Recently, long noncoding RNAs (lncRNAs) have been demonstrated to be dysregulated in various types of cancer. However, the specific mechanisms by which lncRNAs influence breast cancer have remained largely unclear. To bridge this research gap, the present study focused on the lncRNA LINC00365, which is expressed at a low level in breast cancer. Secretoglobin family 2A member 1 (SCGB2A1) was identified as a potential target protein regulated by LINC00365. The results of the present study demonstrated that the overexpression of LINC00365 and SCGB2A1 inhibited cell viability and induced cell apoptosis through the inhibition of the NF-κB signaling pathway in breast cancer cells. These findings indicated that LINC00365 may serve a crucial role in breast cancer and may be considered as a novel target for the clinical treatment of breast cancer.
