Further, to unravel the mechanism by which HAND2-AS1 can bring about a tumor-suppressive effect, an mRNA network (Figure 5a) using genes positively and negatively correlated with HAND2-AS1 (Supplementary Table S2) was constructed after examining their expression in HGSC samples (TCGA-OV) in cBioportal [29,30]. Here, HAND2 is linked to neoplasm.
