Methods: Total RNA was isolated from patients with prostate cancer and from normal people, and poly(A) RNA was further purified. Then differentially expressed genes were analysed in CaP and normal prostate by cDNA macroarray system. Results: There were differential expressions of nine prostate-associated specific genes in CaP as compared with normal prostate, among which, 7 were significantly up-regulated and 2 were down-regulated. Conclusion: As a diagnostic approach at molecular level, the cDNA macroarray is supposed to elevate the detection rate of CaP.展开更多

DNA array is a new bio-technology for disease diagnosis. This study was conducted to diagnose prostate cancer with cDNA macroarray and analysis gene expression profiles of some selective genes in prostate cancer. Methods Total RNA was isolated from patients with prostate cancer and from normal people, and poly（A） RNA was further purified. Then it was analyzed for differentially expressed genes in prostate cancer and normal prostate by cDNA macroarray system. Results There were different expressions in the nine prostate-associated specific genes in prostate cancer as compared with normal prostate, in which, 7 were significantly upregulated and 2 were down-regulated. Conclusion As a diagnostic approach at molecular level, the cDNA macroarray is an effectively diagnostic method for orostate cancer.展开更多
