On the other hand, increased expression of eEf2 (eukaryotic translation elongation factor 2), UNC80 (unc-80 homolog), and STK39 (STE20/SPS1-related proline-alanine-rich protein kinase) have been associated with non-small cell lung cancer [32, 33] and tumorgenesis [34, 35], with corresponding peptides found here increased by 9.29-fold, 10.92-fold and 9.08-fold, respectively. Here, EEF2 is linked to non-small cell lung carcinoma.
