摘要
目的探讨良性前列腺增生(BPH)衰老逃逸现象的机理。方法采用端粒重复片段扩增法(TRAP)分别检测13例正常前列腺组织、35例BPH组织及33例增生结节和包膜的端粒酶活性表达情况,比较端粒酶活性水平与BPH衰老逃逸的关系。结果正常前列腺组织中端粒酶阳性2例(15%),BPH组织中端粒酶阳性17例(49%),增生结节端粒酶阳性14例(42%),包膜阳性1例(3%);BPH组织端粒酶阳性表达率高于正常前列腺组织(P<0.05),增生结节阳性率明显高于包膜组织(P<0.01)。结论BPH组织中端粒酶活性升高,且分布不均匀。提示前列腺衰老逃逸可能与端粒酶活性有关。
Objective To study the mechanism of senile escaping of benign prostatic hyperplasia(BPH) condition. Methods With polymerase chain reaction based telomeric repeat amplification protocol assay(TRAP),telomerase activity was examined in 13 normal prostate tissues,35 benign prostatic hyperplasia tissues,33 hyperplastic tubercle and diaphragm. Results Telomerase activity was detected in 2 of 13(15%)normal prostate tissues,17 of 35(49%)benign hyperplasia tissues,14 of 33(42%)hyperplastic tubercle tissues and 1 of ...
