Pseudogene DUXAP10 can be used as a diagnostic and prognostic biomarker in human cancers.

The pseudogene DUXAP10 is overexpressed in numerous types of human cancers. However, the diagnostic and prognostic value of DUXAP10 in cancers has yet to be characterized. PubMed, EMBASE, Web of Science, the Cancer Genome Atlas (TCGA), and Gene Expression Omnibus databases were comprehensively searched in this study. A total of 50 studies comprising 11,292 patients were collected in this integrated analysis. DUXAP10 was confirmed to be significantly overexpressed in various human cancers (p < .05). Summary receiver operating characteristic (SROC) curve analysis was implemented, which indicated that DUXAP10 was a potential diagnostic biomarker for human cancers (area under the curve [AUC] of SROC curve = 0.81 [0.77-0.84]; pooled sensitivity = 0.69 [0.62-0.75]; pooled specificity = 0.81 [0.73-0.87]). In addition, hazard ratios (HRs) with 95% confidence intervals (CIs) were obtained to evaluate the association of DUXAP10 expression with overall survival (OS) time of cancer patients. Outcomes of meta-analysis suggested that upregulation of DUXAP10 was closely associated with poor OS (pooled HR = 1.11 [1.03-1.18]). Our study revealed that the pseudogene DUXAP10 was upregulated in multiple types of cancers and could be a potential biomarker with good diagnostic and prognostic value for human cancers.
