SNAI2 and colorectal cancer: miR-506 was shown to inhibit EMT by targeting snail family transcriptional repressor 2 (SNAI2), vimentin (VIM), cadherin 2 (CDH2), CD151 molecule (CD151), ETS proto-oncogene 1 (ETS1), and enhancer of zeste 2 polycomb repressive complex 2 subunit (EZH2) in ovarian, breast, gastric, and colorectal cancers [13, 14, 17, 45, 46].
