NRG1 and glioma: Furthermore, the study also showed that the expression of Nrg1 in glioma specimens was negatively correlated with the expression of miR-125a-3p (Fig. 1A), and that there was a positive correlation between the expression of Nrg1 and the survival time of the same cohorts of patients (p<0.01) (Fig. 1B, right).
