【摘要】 目的 :研究重组人白细胞介素 - 13 (rhIL - 13 )刺激巨核细胞系 -HEL细胞的增殖是否与原癌基因c -mpl表达有关。方法 :用MTT比色法和RT -PCR法 ,分别观察了rhIL - 13对HEL细胞增殖的影响和对c -mplmRNA表达的影响。结果 :rhIL - 13促进了HEL细胞的增殖 ,上调了HEL细胞c-mplmRNA的表达。结论 :rhIL - 13促进巨核细胞系 -HEL细胞增殖 ,其部分机制可能是通过上调c -mpl的表达来实现。更多还原

【Abstract】 AIM:To investigate the relevance of the proliferation of megakaryocytic cell line-HEL stimulated by the recombinant human interleukin-13 (IL-13) to the expression of pro-oncogene c-mpl in HEL cells. METHODS: MTT colorimetric assay and reverse transcrition polymerase chain reaction (RT-PCR) are separately used in this study to observe the effect on the proliferation of HEL cells and the expression of c-mpl mRNA in HEL cells by rhIL-13. RESULTS: RhIL-13 stimulated the proliferation of HEL cells and upregulated the expression of c-mpl mRNA in HEL cells. CONCLUSION: Our results suggest that rhIL-13 stimulated the proliferation of HEL cells and provide the evidence that its mechanism is partly because of increasing the pro-oncogene c-mpl expression in HEL cells.更多还原
