As shown in Figures 7(c) and 7(d), no significant difference in the expression of lncRNAs was observed in early stage of BC when comparing normal and tumor tissues, while the expression of the CCDC18-AS1 was significantly increased in stages II-III of disease compared to the control group (|−dct| = 1.5 and 2, respectively, and p < 0.0001). This evidence concerns the gene CCDC18 and breast cancer.
