Meanwhile, Western blot data exhibited that relative to the NC group, Fibronectin and Vimentin expression was memorably increased, E-cadherin and β-Catenin expression was prominently decreased in miR-1303 mimics group, while the expression changes of these four proteins mediated by miR-1303 also could be dramatically reversed by circ_0002980 overexpression in LC cells (Figure 5C, 5D). Here, FN1 is linked to laryngotracheoesophageal cleft.
