To determine the biological functions of LINC00673 in breast cancer cells, siRNAs were designed to silence LINC00673 in MDA-MB-231 and MDA-MB-453 cell lines and lentiviruses were designed to express LINC00673 in the Hs-578 T cell line (Fig. 2a). This evidence concerns the gene LINC00511 and breast carcinoma.
