Abstract:
Objective This study is to investigate the expressions of MACC1 and c-Met genes in prostate cancer tis?sues and to explore the relationship between these gene expressions with the development, invasion and metastasis of pros?tate cancer. Methods The expressions of MACC1 and c-Met genes were examined in 30 cases of benign prostatic hyperpla?sia and 67 cases of prostate cancer using citron acid-microwave-SP immunohistochemical method and analysed with their clinical pathological features. Results Expressions of MACC1 and c-Met in prostate tissues show statistical difference ac?cording to Gleason score, PSA level, pathological stages and whether bone metastasis occurs after radical surgery ( P<0.05 or P < 0.01), but their expressions in prostate tissue show no significant difference among different sex, age and whether smoking or not. Expression of MACC1 in prostate tissue of stageⅢandⅣcancer is significantly higher than that in benign prostatic hyperplasia (BPH) tissues (P<0.05) while the expression of c-Met only shows statistical difference in prostate tis?sue of stage Ⅳcancer compared with that in BPH (P < 0.05). There is a positive correlation between the expression of MACC1 with expression of c-Met in prostate cancer tissues (P<0.01). Kaplan-Meier curves revealed that the survival rates was lower and survival time of bone-free metastasis were shorter in patients with high MACC1 and c-Met expressions in prostate tissue than those with low expressions of MACC1 and c-Met in prostate tissue. Conclusion Expression of MACC1 and c-Met is closely related to the development, invasion and metastasis of prostate cancer, so MACC 1 and c-Met may be used as promising diagnostic and prognostic markers for prostate tumor, and as new therapeutic targets for prostate cancer.
