| 摘 要： | 目的：研究外源HCAP1基因产物对Burkitt淋巴瘤细胞系Raji细胞凋亡及凋亡相关蛋白Bax／Bcl-2的作用。方法：用脂质体介导的基因转移方法，把外源HCAP1基因转染到Raji细胞中，用流式细胞术和Hochest 33258荧光染色检测细胞凋亡；用Western blot检测外源HCAP1基因对凋亡相关蛋白Bax和Bcl-2蛋白表达的调节。结果：外源HCAPl基因导入Raji细胞24、48和96h后，细胞凋亡率增加。Western blot显示Bax／Bel-2蛋白表达比值明显增高。结论：转染外源性HCAP1基因可诱导Raji细胞凋亡，使Bax／Bcl-2蛋白表达比例上调可能是HCAP1诱导凋亡的机制之一。 |

| Abstract: | Aim: To investigate the effect of exogenous HCAP1 gene products on apoptosis and apoptotic related proteins Bax and Bcl-2 in Burkitt lymphoma cell line Raji. Methods: HCAP1 gene was transfected into the Raji cells by the medium of liposome. The cell apoptosis was examined by means of flow cytometry and Hochest 33258 fluorescein staining. The levels of apoptotic related proteins Bax and Bcl-2 were measured by Western blot. Results: The percentage of apoptotic cells was significantly increased in the Raji cells transfected with HCAP1, as compared with the Raji cells transfected with PBK/CMV empty vector, at 24,48 and 96 hours after transfection. Western blot showed the expression ratio of the Bax to the Bcl-2 was increased. Conclusion: Overexpression of HCAP1 gene could induce apoptosis of the Raji cells. The upergulation of the expression ratio of Bax to Bcl-2 may be involved in the pathway of apoptosis induced by HCAP1 gene. |
| Keywords: | HCAP1 gene Raji cell apoptosis Bax/Bcl-2 protein |
