To examine whether LSD1 and/or G9a expression is correlated with the clinical and pathophysiological characteristics of EC, we analyzed The Cancer Genome Atlas (TCGA) database via the Ualcan (http://ualcan.path.uab.edu/index.html) and GEPIA (http://gepia.cancer-pku.cn) websites [23, 24]. This evidence concerns the gene KDM1A and cancer.
