SP1 and central nervous system cancer: miR‐5188 levels were negatively associated with FOXO1 mRNA levels (Figure 7D; r = −0.3380, P = .0329), but positively correlated with c‐JUN mRNA levels (Figure 7D; r = 0.2975, P = .0003) and SP1 mRNA levels (Figure 7D; r = 0.2116, P = .0028) in the glioma specimens.
