FAS and granular cell tumor: The identified differentially regulated proteins from this comparative proteomic study of GCT-untreated/control and treated were strongly involved in some potential pathways including angiogenesis (1.5%), apoptosis signaling (6%), CCKR signaling (2%), Integrin signaling (10.4%), Glycolysis (7.5%), cytoskeletal regulation by Rho GTPase (4%), FAS signaling (3%), p38 MAK pathway (3%), VEGF signaling (5%), etc., were showed in Figure 5.
