Moreover, SAA1 inhibition reduced the expression of the metastasis‐related proteins MMP9 and integrin αVβ3 in both GBM cell lines and patients' GBM cultures (Figs 3I, 4A); neutralizing the secreted form of SAA1 in medium successfully reduced glioma cell migration and invasion. The gene discussed is MMP9; the disease is glioblastoma.
