The expression of LINC00665, miR-379-5p, and LIN28B in breast cancer and normal breast tissues were obtained from the TCGA database and we found upregulation of LINC00665 and LIN28B expression and a downregulation of miR-379-5p expression in breast cancer tissues (Fig. 6a–c). This evidence concerns the gene LINC00665 and breast carcinoma.
