NF‐κB interacting LncRNA (NKILA), encoded by a gene at chromosome 20q13 just near by the prostate transmembrane protein androgen induced 1 (PMEPA1),96 was increased by NF‐κB in breast cancer.97 Recently, Lu et al discovered that NKILA expression was negatively associated with tumour metastasis in patients with NSCLC, and the expression of NKILA was regulated through classical TGF‐β signal pathway, which subsequently inhibited migration and invasion of NSCLC cells through interfering NF‐κB/Snail signal pathway in NSCLC cells.98 Here, PMEPA1 is linked to breast carcinoma.
