MiR-103 Assumes Signifying Capacity in Prostate Cancer Diagnosis
Background: Prostate cancer is one of the common cancers among males with high incidence and mortality. MiR-103 has been reported to be involved in several human cancers. In our study, we aimed to explore the diagnostic value of miR-103 in PCa.
Methods: In this study, qRT-PCR was performed to investigate the expression levels of miR-103 in serum specimens collected from 141 PCa patients and 77 healthy volunteers. MTT and cell invasion assay were performed to detect the effects of miR-103 on the proliferation and invasion of PCa cells. The diagnostic value of miR-103 in PCa was evaluated by ROC curve.
Results: The results showed that serum miR-103 levels were higher in PCa patients than that in healthy group (P<0.001). And the expression of miR-103 was significantly associated with PSA (P=0.007), differentiation (P=0.009), and lymph node metastasis (P=0.037). Cell experiments in vitro demonstrated that miR-103 could promote PCa cell line proliferation and invasion. In addition, ROC analysis suggested that miR-103 could discriminate between PCa patients and healthy individuals at the cut-off value of 0.970. The AUC was 0.885, with the sensitivity of 97.2% and specificity of 81.8%.
Conclusions: The increased miR-103 levels can promote proliferation and invasion of PCa cells. Serum miR-103 is significantly associated with tumor progression, which may be a novel biomarker for PCa diagnosis.
