VIM and astrocytoma (excluding glioblastoma): Some proteins previously identified as deiminated in hypoxic astrocytoma cell lysates [34] were here identified in both LN18 and LN229 under normal culture conditions, including cytoskeletal proteins (vimentin, filamin-A, cytoplasmic actin-1) and stress-related proteins (GRP78: 78 kDa glucose-regulated protein and G3P: Glyceraldehyde-3-phosphate dehydrogenase) (Table S1).
