S100A11 and non-small cell lung carcinoma: Comparative proteomics analysis of two NSCLC cell lines, the nonmetastatic CL1-0 and highly metastatic CL1-5, performed by 2DE followed by matrix-assisted laser desorption ionization-time of flight (MALDI-TOF)/MS and MS/MS and validated by RT-PCR and Western blotting, revealed an upregulation of S100A11 in metastatic CL1-5 cells [38].
