MMP9 and glioblastoma: The correlation analysis observed that SCIN positively correlated with the expression of MMP2 (Spearman correlation coefficient r = 0.357, p < 0.001, Figure 3E) and MMP9 (Spearman correlation coefficient r = 0.356, p < 0.001, Figure 3F) in TCGA RNA seq datasets for glioblastoma and low-grade glioma (TCGA GBMLGG).
