TIMP3 and laryngotracheoesophageal cleft: Then the ceRNA network containing 3 lncRNAs (GATA2-AS1, LINC00632 and MIR99AHG), 1 miRNA (has-miR-21-5p) and 5 targeted genes (RECK, TIMP3, EHD1, RASGRP1 and ERG) was constructed to reveal the regulatory interaction between lncRNA-miRNA-mRNA and figure out potential biomarkers for LC.
