Moreover, we examined the coexpression pattern of NORAD and hsa‐miR‐155‐5p in ovarian serous cystadenocarcinoma using Pan‐Cancer database (http://starbase.sysu.edu.cn/panMirCoExp.php), and found out that NORAD and hsa‐miR‐155‐5p expressions were statistically correlated (Figure 4E). This evidence concerns the gene NORAD and ovarian serous cystadenocarcinoma.
