Background: This pilot study is the first to focus on the potential role for death-associated protein 3 (DAP3) in human breast cancer. Materials and Methods: A total of 153 samples were studied. The levels of transcription of DAP3 were determined using quantitative polymerase chain reaction (qPCR). Transcript levels within breast cancer specimens were compared to those of normal background tissues and correlated with clinicopathological data accumulated by over a 10-year follow-up period. Results: The expression of DAP3 mRNA was demonstrated to decrease with increasing Nottingham Prognostic Index (NPI2 vs. 3, p=0.036), TNM stage (TNM1 vs. 3, p=0.07), and tumour grade (grade 1 vs. 3, p=0.08). Lower DAP3 expression levels were significantly associated with local recurrence (p=0.013), distant metastasis (p=0.0057) and mortality (p=0.019). Conclusion: This study demonstrates an inverse association between DAP3 mRNA levels and tumour stage and clinical outcome in breast cancer, consistent with the pro-apoptosis function of DAP3. Further research is required in order to confirm our findings and clarify the mechanisms that regulate DAP3 expression in human breast cancer.
