Additional file 2: Figure S2B shows LC-MS/MS analysis of the constituent disaccharides of GAGs related to altered expression of SRGN in NSCLC cells, which revealed high levels of ∆CS-0S, ∆CS-4S, ∆CS-6S, ∆HS-0S and ∆HS-NS disaccharides related to SRGN expressed by both H1299/SRGN and H460/sh-CTRL cells. Here, SRGN is linked to non-small cell lung carcinoma.
