端粒酶是维持端粒长度的逆转录酶 ,在大多数正常人体细胞中无端粒酶活性 ,而在干细胞、生殖细胞和 90 %的恶性肿瘤细胞中有端粒酶活性。我们应用核酸原位杂交 (ｎｕｃｌｅｉｃａｃｉｄｉｎｓｉｔｕｈｙｂｒｉｄｉｚａｔｉｏｎ)技术 ,对睾丸肿瘤组织和正常睾丸组织中人端粒酶Ｒ?
Telomerase is a reverse transcriptase that maintains telomere length, has no telomerase activity in most normal human cells, and telomerase activity in stem cells, germ cells, and 90% of malignant cells. We use nucleic acid in situ hybridization (nucleicacidinsituhybridization) technology, testicular tumor tissue and normal human testicular telomerase R?
