Then, we compared FTO and ALKBH5 transcriptome and proteogenomic expression between tumor and normal tissues in The Cancer Genome Atlas (TCGA), the Genotype-Tissue Expression (GTEx) dataset (http://gepia.cancer-pku.cn/index.html) and the Clinical Proteomic Tumor Analysis Consortium (CPTAC) Data Portal (https://cptac-data-portal.georgetown.edu/cptac/s/S045) [23]. The gene discussed is FTO; the disease is cancer.
