DANCR and breast cancer: Figure 1A showed that DANCR was significantly up-regulated in tumor tissues compared with normal tissues, implying that DANCR might be related with breast cancer progress. Then the 57 TNBC patients were divided into two groups based on DANCR expression level: high expression group (n = 25) and low expression group (n = 32) (Figure 1B). We analyzed the overall survival of patients in the two groups and the results displayed that the percent survival in low expression group was obviously higher than that in high expression group (Figure 1C).
