TP73 and central nervous system cancer: We found that for WHO grade III gliomas, the high expression of TP73-AS1 indicated a poor prognosis for primary gliomas in the TCGA, CGGA, and GSE16011 and for recurrent gliomas of CGGA (Figure 3I–3L); however, the relation of high TP73-AS1 expression with poor prognosis was not obvious in WHO grade II (Figure 3E–3H) and WHO grade IV (Figure 3M–3P) gliomas.
