促血小板生成素(TPO,thrombopoietin)通过其受体c-Mpl调控巨核细胞发育以及促进血小板生成,与多种肿瘤预后和生存有负相关性,这与循环TPO的内化降解及c-Mpl可变剪接体c-Mpl-D内吞有关。本研究首先用逆转录表达系统构建了UT-7/c-Mpl-D稳定系细胞以研究c-Mpl-D单独存在情况下的功能,通过电转的方式构建了Dami/c-Mpl-D稳定系细胞,进行研究c-Mpl-D对c-Mpl-F功能的调控,进一步通过交联剂与免疫共沉淀研究c-Mpl-D与TPO的相互作用。结果表明当c-Mpl-D与c-Mpl-F共存时,c-Mpl-D可促进Dami细胞增殖,抑制Dami细胞凋亡,阻止Dami细胞往巨核细胞方向成熟。同时,c-Mpl-D在细胞中TPO刺激后显著降低了受体内化效应。综上所述,本研究提出了随巨核细胞分化成熟c-Mpl-D表达量不断上升相关生理意义的模型,为c-Mpl-D和巨核细胞增殖分化的关系提供了新的认识,为巨核细胞增殖分化机制的分析提供了新的实验依据,对c-Mpl-D相关病症的预防、诊断及治疗起到推动作用。
Thrombopoietin (TPO) regulates the development of megakaryocytes and the production of platelets through its receptor c-Mpl, and has a negative correlation with the prognosis and survival of various tumors, which is related to the internalization and degradation of circulating TPO and the endocytosis of the c-Mpl splice variant c-Mpl-D. This study constructed a UT-7/c-Mpl-D stable cell line using a reverse transcription expression system to study the function of c-Mpl-D in isolation. A Dami/c-Mpl-D stable cell line was also constructed by electroporation to investigate the regulatory effect of c-Mpl-D on c-Mpl-F function. Further, the interaction between c-Mpl-D and TPO was studied using crosslinking and immunoprecipitation. The results indicated that, when coexisting with c-Mpl-F, c-Mpl-D can promote Dami cell proliferation, inhibit Dami cell apoptosis, and prevent Dami cells from maturing towards megakaryocytes. Additionally, c-Mpl-D significantly reduced the receptor internalization effect after TPO stimulation. In summary, this study proposes a model related to the physiological significance of the increasing expression of c-Mpl-D with the differentiation and maturation of megakaryocytes, providing new insights into the relationship between c-Mpl-D and the proliferation and differentiation of megakaryocytes. It offers new experimental evidences for the analysis of the mechanisms of megakaryocyte proliferation and differentiation, and promotes the prevention, diagnosis, and treatment of c-Mpl-D-related diseases.
