Objective To investigate the expression of NEK2(NIMA-related kinase 2)in prostate cancer as well as benign prostatic hyperplasia,and the involvement of NEK2 in the prognosis of prostate caner(PCa). Methods The different expression of NEK2 in the tissue of prostate cancer and the adjacent benign tissues of prostate were measured by real-time quantitative reverse transcriptase-polymerase chain reaction (QRT-PCR) analysis and immunohositochemistry analysis,and then bioinformatically analyzed using the Taylor dataset. Results QRT-PCR showed that NEK2 was highly expressed in PCa than in the adjacent benign tissues (6.93±0.15 vs 5.38±0.4,t=6.25,P=0.003). Immunohositochemistry analysis showed the expression of NEK2 was higher in PCa than in the adjacent benign tissues(5.84±0.56 vs 4.27±0.49,t=5.38, P<0.001). Furthermore, the biochemical recurrence-free time of PCa patients in high NEK2 expression groups significantly reduced( χ²=4.33,P=0.037). The overall survival time of PCa patients was not correlated to NEK2 expression levels( χ²=0.27,P=0.605). Conclusion The above findings suggest that NEK2 is associated with production and development of PCa, and also critically connected with the process of PCa,which indicate that we can predict the probability of the biochemical recurrence-free time by detecting the expression of NEK2 in PCa patients,and NEK2 can also become a potential biomarker for PCa prognosis.
