The top 15 biological processes in the GO and KEGG pathways showed that HOTAIR participates in “GO:0016477~cell migration”, “Hippo signaling pathway”, “Ubiquitin-mediated proteolysis”, and “TGF-beta signaling pathway” (Figure 6A,B), which are correlated with tumorigenesis and cancer metastasis [31,32,33]. Here, HOTAIR is linked to cancer.
