S100A4 and glioblastoma: Further, the data obtained from Gene Correlation Analysis showed that the expression of TUBA1C was positively correlated to the expression of CLDN5 and S100A4; MAP1LC3B expression was positively correlated to the expressions of Bnip3, Nix and LAMP1; LAMP1 expression was positively correlated to S100A4 expression in GBM (Fig. 1e).
