NEDD9 and non-small cell lung carcinoma: It has been previously reported that A549 cell lines lack LKB1 and this absence presumably contributes to the upregulation of NEDD925, 26.Testing for the presence of LKB1 in NSCLC-N6-L16 cells showed the expression of the gene in the cell line (data not shown), implying that the overexpression of NEDD9 after 16 hours can only be a consequence of the treatment with A190.
