HELLPAR and central nervous system cancer: Survival analysis was performed on 10 lncRNAs (AL359924.1, HOTAIR, TMEM132D-AS1, and AC239868.1 could not be analyzed because the number of zeros in the sequence-data was more than half), and high levels of AC084117.1, LINC02432, HOXA11-AS, HELLPAR, H19, and AL021392.1 were related to poor prognosis of gliomas patients (Fig. 10A).
