Moreover, we divided these glioma patients into two groups, high expression of LINC00461 and low expression of LINC00461 according to the mean of LINC00461 level (Table 1), and found that high LINC00461 expression was correlated with larger tumor size, higher WHO grade, recurrence, and shorter cumulative 5-year survival rate (Figure 1c). Here, MIR9-2HG is linked to central nervous system cancer.
