Abstract | BACKGROUND: METHODS: We utilized the University of Alabama interactive web resource to identify novel biomarkers observed in 79 adrenocortical carcinoma patients. Identified biomarkers were then examined for prognostic correlations using the cBioPortal and analyzed for statistical significance using STATA 13.0. RESULTS: The Cancer Genome Atlas data mining in the University of Alabama interactive web resource for pathways associated with poor survival of patients with adrenocortical carcinoma revealed significant upregulation of genes involved in DNA damage and regulation of cell-cycle pathways, such as AURKA, AURKB, CDK1, CDK4, CDK6, PLK1, CHEK1, CHEK2, CDC7, BUB3, and MCM3 (P < .001-.05). On outcome correlation, greater expression levels of all the genes except CDK4 were associated with worse survival compared with medium or low levels of gene expression (P < .001 all) irrespective of age orsex. Consistent with our University of Alabama interactive web resource findings, data mining in the cBioPortal also revealed upregulation of genes regulating DNA-damage and cell cycle-related genes in 82% of patients (z score = 1.5). CONCLUSION: Large data mining from the The Cancer Genome Atlas and cBioPortal databases identified overexpression of genes involved in DNA damage and those regulating pathways of the cell cycle, which correlated with poorer overall survival in adrenocortical carcinoma patients.
