For instance, LINC00461, DANCR, H19, HOX transcriptional anti-toxic intergenic RNAs (HOTAIR), LINC00152, LINC01857 and NEAT1 facilitate BC cell invasion and migration; and HOTAIR, H19, MALAT1, RP1 and HIF1A-AS2 promote BC cell long-distant metastasis. This evidence concerns the gene HIF1A and breast cancer.
