CCNB2 and central nervous system cancer: The results of correlation analysis of clinical variables between CCNB2 and lower grade gliomas showed that in both the mRNAseq_325 dataset and mRNAseq_693 dataset, the expression of CCNB2 was correlated with different histological grades, age, IDH mutational status, and 1p/19q codeletion status (Figures 2 and 3).
