| 摘要: |
| 目的：建立雄激素非依赖性前列腺癌细胞亚系模型LNCaP-AI。方法：长期在去雄激素的血清环境下培养雄激素依赖性LNCaP细胞，培养出能够适应无雄激素环境的LNCaP-AI细胞亚系。MTT、RT-PCR、免疫荧光方法观察LNCaP-AI细胞在无雄激素环境下的增殖能力和表达及分泌前列腺特异性抗原（PSA）的水平。结果：LNCaP前列腺癌细胞在无雄激素中培养3个月后逐渐适应了无雄激素的环境，成为雄激素非依赖的LNCaP-AI细胞亚系。LNCaP-AI细胞在无雄激素的环境下迅速增殖，能够分泌 PSA，但其PSA mRNA的表达水平是正常生长LNCaP细胞的44%。结论：成功构建雄激素非依赖性前列腺癌细胞亚系模型LNCaP-AI，可以模拟前列腺癌由雄激素依赖发展为雄激素非依赖的过程。 |

| Abstract: |
| Objective：To establish an androgen-independent human prostate cancer cell line model LNCaP-AI. Methods: LNCaP cells were cultured in absence of hormone for a long-term to establish LNCaP cell line LNCaP-AI, which can live without hormone. MTT, immunofluorescence and RT-PCR techniques were used to study the proliferation activity of LNCaP-AI cells and expression and secretion level of PSA by LNCaP-AI cells in absence of hormone.Results: After cultured for 3 months, LNCaP cells gradually became accustomed to the non-hormone condition, showing the characteristics of androgen-independent LNCaP-AI cell line. LNCaP-AI cells rapidly proliferated under the non-hormone condition and secreted PSA.However, PSA mRNA expression level in LNCaP-AI cells was 44% that of the LNCaP cells under hormone condition.Conclusion: Androgen-independent LNCaP-AI cell line may simulate the development of androgen-independence in prostate cancer cells and is an ideal model of androgen-independent prostate cancer cell line. |
