Aim
To investigate the role of gelsolin-like actin-capping protein (CapG) in prostate cancer (PCa). Materials &
Conclusion
CapG, as a potential biomarker in PCa, is associated with patient prognosis, cellular apoptosis and proliferation.
Methods
CapG expression and its correlation with clinicopathological characters and patient prognosis were analyzed in 76 cases of PCa by immunohistochemistry and qRT-PCR. Then, the influence of CapG downregulation on cell apoptosis and proliferation were assessed.
Results
CapG expression in PCa was significantly higher compared with those in matched adjacent noncancerous prostate tissues, and significantly correlated with clinicopathological characters. Survival analysis indicated that CapG could be an independent prognostic factor in PCa. Moreover, CapG depletion significantly affected cellular proliferation and apoptosis by regulating Caspase 6/Caspase 9/Bcl-2/p-Akt/Akt signaling pathway.
