【Abstract】〓Objective〓To investigate the association of MYL9 expression with tumor progression and prognosis in patients with prostate cancer (PCa). Methods〓MYL9 protein expressions in human PCa and non-cancerous prostate tissues were detected by immunohistochemistry analyses. Then,the associations of MYL9 expression with clinicopathological features and clinical outcome of PCa patients were statistically analyzed. Results〓Immunohistochemistry analyses showed that MYL9 expression significantly decreased in PCa tissues as compared with those in non-cancerous prostate tissues. In addition, MYL9 was mainly expressed in the cytoplasm of stromal cells of prostate tissues, and the decreased expression of MYL9 in PCa tissues was significantly correlated with the higher Gleason score. Conclusion〓Our data strongly confirmed for the first time that the decreased expression of MYL9 may play an important role in tumor progression of PCa.
