MMP9 and Stroke: The diagnostic model indicated that the Fos proto-oncogene, the AP-1 transcription factor subunit (FOS), matrix metalloproteinase 9 (MMP9), phosphatase and tensin homolog (PTEN), tissue inhibitor of metalloproteinase 1 (TIMP1), and toll-like receptor 2 (TLR2) could be used as blood biomarkers for stroke [82].
