Abstract:
OBJECTIVETo investigate the expressions of survivin and GRIM-19 in prostatic cancer tissue and their clinical implications.
METHODSWe detected the expressions of survivin and GRIM-19 in the tissues of normal prostate (NP), benign prostate hyperplasia (BPH) and prostate cancer (PCa) using immunohistochemical staining, RT-PCR and Western blot, and processed the data by SPSS12.
RESULTSThe positive rates of survivin expression were 6.25% , 18.18% and 90.62% in NP, BPH and PCa (P < 0.01), while those of GRIM-19 were 87.50%, 81.82% and 9.37% , respectively (P < 0.01). Semiquantitative RT-PCR and immunohistochemical staining showed that both survivin mRNA and survivin expressions were highly positive in PCa but negative in NP and BPH. Western blot exhibited that the survivin protein was expressed strongly in PCa but weakly in NP and BPH, while the GRIM-19 protein was expressed just contrariwise (P < 0.01).
CONCLUSIONThe expressions of survivin and GRIM-19 may be closely correlated with the pathogenesis of prostate cancer.
