近日,国际学术期刊Oncogene 在线发表了中国科学院上海生命科学研究院健康科学研究所时玉舫研究组题为p53 Regulates Mesenchymal Stem Cell-mediated Tumor Suppression in a Tumor Microenvironment through Immune Modulation 的研究论文,报道了抑癌基因p53缺失在间充质干细胞(Mesenchymal stem cells, MSCs)塑造肿瘤微环境中的重要作用。

p53是著名的抑癌基因之一,大约50%的恶性肿瘤中存在它的突变。然而,之前的研究大多集中于探讨肿瘤细胞中p53的突变,而肿瘤基质细胞中的p53表达变化是否会影响肿瘤的发生尚未得到太多关注。目前,作为肿瘤微环境中的重要组成之一,肿瘤基质干细胞对肿瘤生长的重要影响正得到越来越多的关注。有报道显示,肿瘤周围的基质细胞中的确可以观察到p53的突变,但这种表达的变化对肿瘤生长的影响及机制仍不清楚。

博士研究生黄寅等通过一系列研究发现,相比于正常小鼠,黑色素瘤细胞在p53缺失小鼠中的生长更迅速,提示肿瘤基质环境中p53的突变也可以影响肿瘤的生长。由于MSCs可以被招募到肿瘤部位并成为肿瘤微环境的主要组成之一,他们进而将黑色素瘤细胞与分别来源于野生型或p53缺失小鼠骨髓的MSCs共接种到C57BL/6小鼠上,结果显示来源于p53缺失小鼠的MSCs显著地促进肿瘤生长,但是,这种作用并未在免疫缺陷小鼠中观察到。因此,p53缺失MSCs主要通过调节肿瘤部位的免疫反应调控肿瘤生长。p53缺失MSCs调控肿瘤免疫反应的机制与它受炎症因子刺激后,表达更高水平的一氧化氮合成酶及其相应的产物一氧化氮密切相关,从而比野生型MSCs具有更强的免疫抑制作用。当在体内肿瘤模型中使用一氧化氮合成酶抑制剂S-甲基异硫脲硫酸盐(SMT)时,p53缺失MSCs的促肿瘤作用也会消失。因此,他们的研究证明了肿瘤基质细胞中p53的表达状态在肿瘤发生中发挥重要作用,而这一作用是通过调节免疫反应实现的。该研究为癌症治疗提供了新的靶点和方向。

该研究得到了国家科技部、中国科学院战略性先导科技专项、中国科学院知识创新工程重大项目、国家自然科学基金委的资助。
