Results The mRNA level of the PECK gene on the prostate carcinoma cell strains(DU-45,LNCap and PC-3) was lower than that on the benign prostate hyperplasia cell strain BPH-1,while the matrix metalloproteinase-2 (MMP-2) level was higher.

• 应用Westernblot检测不同前列腺细胞株中RECK基因的表达。 结果前列腺癌细胞株DU-145、LNCap以及PC-3中RECKmRNA的表达较良性前列腺增生细胞株BPH-1中明显降低(P<0.；01)；MMP-2mRNA表达则明显升高。
