For example, HOTAIR is frequently overexpressed in breast cancer and has been shown to promote cell growth and migration by modulating multiple signaling pathways, including FGFR and Wnt/catenin pathways; while can also facilitate the invasiveness and metastasis of breast cancer by stimulating gene expression via the targeting of PRC2 and reducing Akt/JNK signaling pathway [18, 19]. This evidence concerns the gene HOTAIR and breast carcinoma.
