However, its role in breast cancer (BRCA) is undetermined.<h4>Methods</h4>Differential expression analyses using The Cancer Genome Atlas (TCGA) data, clinical samples and cell lines were performed. Lentiviral knockdown and overexpression experiments were performed to detect changes in cell morphology, molecular markers and invasion. Chromatin immunoprecipitation-sequencing (ChIP-Seq) and luciferase reporter assays were performed to detect the SLFN5-binding motif.<h4>Results</h4>TCGA, clinical samples and cell lines showed that SLFN5 expression was negatively correlated with BRCA metastasis.
