For 14 complete interactomes (HOTAIR/miR-124/ST8SIA4; HOXA11-AS/miR-124-3p/ITGB3; HOXA11-AS/miR-124/Sp1; KCNQ1OT1/miR-124-3p/TRIM14; LINC00240/miR-124-3p/DNMT3B; LINC00511/miR-124-3p/EZH2; LINC01410/miR-124-3p/SMAD5; MALAT1/miR-124/Capn4; MALAT1/miR-124/foxq1; SND1-IT1/miR-124/COL4A1; SNHG16/miR-124-3p/MCP-1; SP1- GCMA/miR-124/SLUG, SNAIL; UCA1/miR-124/JAG1; and XIST/miR-124/AR), involvement in EMT and/or development of metastasis in cancers of the corresponding localizations was revealed [43,59,62,63,64,65,67,70,73,76,90,91,93,94]. Here, JAG1 is linked to cancer.
