In addition, as shown in Figure 1, the expression of LINC00473 [171], TINCR [157], LINP1 [172] and lncRNA breast cancer anti-estrogen resistance 4 (BCAR4) [173,174] were all up-regulated in BC tissues and increased further during metastasis, and they were all associated with poor prognosis of BC patients. This evidence concerns the gene BCAR4 and breast cancer.
