Long noncoding RNA NKILA could be remarkably upregulated by classical TGF-β signal pathway in ESCC. NKILA was significantly downregulated in esophageal squamous cell carcinoma and negatively correlated with TNM stage. NKILA inhibits ESCC cell metastasis via repressing MMP14 expression by suppressing the phosphorylation of IκBα and NF-κB activation.
