Moreover, via the gene expression profiling interactive analysis (GEPIA, http://gepia.cancer-pku.cn/) database, we found that RNF157-AS1 had higher levels in 426 serous ovarian cancer tissues in the TCGA database than 88 normal ovarian tissues in the GTEx database (Fig. 1G). The gene discussed is RNF157; the disease is ovarian serous adenocarcinoma.
