SNAI1 and gastric cancer: For instance, lncRNA LEIGC is a critical regulator in preventing EMT in gastric cancer, as LEIGC knockdown results in highly elevated expression of Snail, Slug, Twist and Zeb (ZEB) genes.78 Recent studies have also highlighted the importance of HOATIR in the regulation of EMT through regulating Snail, Slug, and Twist expression.79 Similarly, ZEB1-AS1 (ZEB1 antisense1) induces EMT by upregulating ZEB1 expression in hepatocellular carcinoma.80
