DLK1 and non-small cell lung carcinoma: miR-129-5p has been found downregulated in NSCLC; however, its upregulation inhibits tumor growth and generates chemoresistance by downregulating DLK1 (delta-like non-canonical Notch ligand 1), which suggest that miR-129-5p and DLK1 may play a relevant role in NSCLC and its treatment [54].
