Figure Lengend Snippet: The protein expression patterns of radiogenomics-based hub genes (A) The protein expression patterns of 7 hub genes between normal brain tissues and glioma were determined by immunohistochemistry (IHC) staining from The Human Protein Atlas (THPA) database. Compared with normal brain tissues, the protein expression levels of hub genes increased in glioma as the grading of the tumor increased, except for CXCL8 and IL-6 without obvious detection. (B) IHC staining of acquired glioma specimens in proliferative core exhibited higher protein expression levels of MMP2, MMP9, TIMP1, COL1A2, and CCL2 in the high-Rad-score group. Compared with the hub gene labeling index (LI) in the low-Rad-score group, LIs of MMP2, TIMP1, and COL1A2 were significantly higher in the high-Rad-score group (∗ p < 0.05; ∗∗ p < 0.01; ∗∗∗ p < 0.001). (C) The expression levels and localization of MMP2, TIMP1, and COL1A2 were shown by the multiplex immunohistochemistry (mIHC) staining. The biological markers represented by different colors are labeled in the figure. The expression of the three genes increased in the high-Rad-score group, and MMP2 exhibited the most significant difference.
