Due to the facts that LINC02568 is localized in both the cytoplasm and nucleus of cells (Figure 3A), and LINC02568 was co‐induced with a divergent gene, CA12, under estrogen stimulation (Figure 1H), we proposed that LINC02568 might function in cis in addition to its in trans mechanism to exert its oncogenic role in ER+ breast cancer. The gene discussed is LINC02568; the disease is breast cancer.
