For example, Zhou et al. [27] reported that LINC00665 was highly expressed in breast cancer tissues and cells, and the high expression of LINC00665 was linked to poor prognosis; deletion of LINC00665 attenuated the migration and invasion ability of breast cancer cells and inhibited epithelial-mesenchymal transition (EMT). This evidence concerns the gene LINC00665 and breast carcinoma.
