FSCN1 and esophageal squamous cell carcinoma: We found that lncRNA-TTN-AS1 upregulates actin-binding protein fascin homolog 1 (FSCN1) by sponging miR-133b, and combines directly with the mRNA-stabilizing protein HuR to stabilize FSCN1 mRNA, resulting in the epithelial-mesenchymal transition cascade in esophageal squamous cell carcinoma (ESCC)8.
