WEE2 and cancer: Furthermore, the relationships between the expression of these lncRNAs and the TNM stages of the patients in the pancancer data from the TCGA cohort were examined, and the expression of eight lncRNAs (WWC2-AS2, WEE2-AS1, TRHDE-AS1, TPT1-AS1, PGM5-AS1, HAND2-AS1, GRIK1-AS1 and EPB41L4A-AS2) was negatively related to advanced stages of cancer, but the relationships of three lncRNAs (WWC2-AS2, TRHDE-AS1 and HAND2-AS1) were not statistically significant (Fig. 2b).
