Compared with the normal breast cancer cell group, the migration rate of the lncRNA TPA overexpression cells was significantly increased, and the migration rate of the lncRNA TPA knockdown cells was significantly reduced after the scratches were performed for 24 and 48 h, respectively (p < 0.01, p < 0.01); The results are shown in Figure 7 and Table 4. This evidence concerns the gene PLAT and breast carcinoma.
