Then, we analyzed the difference in ATG101 expression between normal samples from the GTEx database and tumour tissues from the TGGA database and found that ATG101 expression was upregulated in BRCA, CESC, CHOL, COAD, GBM, HNSC, KICH, LGG, LIHC, LUSC, OV, PAAD, PRAD, READ, SKCM, UCEC and UCS. This evidence concerns the gene ATG101 and neoplasm.
