Aim:
To explore the independent prognostic value of NUP43 in terms of overall survival (OS) and the mechanisms of its dysregulation in breast cancer.
Patients & Methods:
Bioinformatic analysis was performed by using data from The Cancer Genome Atlas-breast invasive carcinoma.
Results:
High NUP43 expression was an independent prognostic factor of poor OS in luminal A subtype (HR: 2.400; 95% CI: 1.070-5.379; p = 0.034) and in HER2+ subtype (HR: 10.578; 95% CI: 1.850-60.473; p = 0.008). NUP43 DNA amplification was associated with elevated NUP43 expression, while DNA deletion was associated with decreased NUP43 transcription.
Conclusion:
NUP43 upregulation was related to DNA amplification and might independently predict poor OS in luminal A and in HER2+ breast tumors.
