Spatiotemporal switching signals for cancer stem cell activation in pediatric origins of adulthood cancer:Towards a watch-and-wait lifetime strategy for cancer treatment

引用

World Journal of Stem Cells 2018年第2期10卷 15-22页

作者： shengwen calvin li Mustafa H Kabeer Neuro-oncology and Stem Cell Research Laboratory Children's Hospital of Orange County Department of Neurology University of California-Irvine School of Medicine Children's Hospital of Orange County Department of Surgery University of California-Irvine School of Medicine

Pediatric origin of cancer stem cell hypothesis holds great promise and potential in adult cancer treatment, however; the road to innovation is full of obstacles as there are plenty of questions left unanswered. First, the key question is to characterize the nature of such stem cells (concept). Second, the quantitative imaging of pediatric stem cells should be implemented(technology). Conceptually, pediatric stem cell origins of adult cancer are based on the notion that plasticity in early life developmental programming evolves local environments to cancer. Technologically, such imaging in children is lacking as all imaging is designed for adult patients. We postulate that the need for quantitative imaging to measure space-time changes of plasticity in early life developmental programming in children may trigger research and development of the imaging technology. Such quantitative imaging of pediatric origin of adulthood cancer will help develop a spatiotemporal monitoring system to determine cancer initiation and progression. Clinical validation of such speculative hypothesis-that cancer originates in a pediatric environment-will help implement a wait-andwatch strategy for cancer treatment.

关键词： Pediatric origins of adult cancer Imaging of single cells

BACKGROUND Radiation induces rapid bone loss and enhances bone resorption and adipogenesis, leading to an increased risk of bone fracture.

For in vitro study, mouse bone marrow mesenchymal stem/stromal cells(BM-MSCs) were irradiated with Co-60 at a single dose of 9 Gy. For osteoclast induction, monocyte-macrophage RAW264.7 cells were cocultured with mouse BM-MSCs for 7 d. Clus Pro and Inter Pro Surf were used to investigate the interaction interface in Crif1 and protein kinase cyclic adenosine monophosphate(c AMP)-activited catalytic subunit alpha complex. Virtual screening using 462608 compounds from the life Chemicals database around His120 of Crif1 was carried out using the program Autodock_vina.

Deletion of Crif1 in BM-MSCs could reduce both adipogenesis and RANKL expression,resulting in the inhibition of osteoclastogenesis.

目的检测CRIF1在骨肉瘤组织、癌旁组织及骨肉瘤细胞系中的表达情况,探讨CRIF1在骨肉瘤细胞放射耐受中的作用及其分子机制,探索抑制CRIF1在裸鼠移植瘤模型放疗增敏中的作用,以及以CRIF1为靶点在骨肉瘤的放疗增敏中应用前景。材料和方法收集新鲜骨肉瘤组织标本和石蜡包埋骨肉瘤组织标本,免疫组化、免疫荧光、RT-PCR以及Western blotting检测CRIF1的表达水平并进行生存率分析。检测骨肉瘤细胞系中CRIF1的表达水平。建立CRIF1稳定低表达的U2OS细胞系,检测CRIF1低表达对对细胞周期、细胞增殖、DNA复制、DNA修复、线粒体结构及膜电位的影响。通过免疫荧光、免疫共沉淀、Western blotting等方法检查CRIF1与CDK2之间的相互作用,以及该作用对放射后CDK2的表达水平、磷酸化状态、亚细胞分布和关键上下游调控分子表达水平的影响。建立CRIF1低表达的裸鼠移植瘤模型,探索其放疗敏感性。结果骨肉瘤肿瘤组织高表达CRIF1,其表达水平与患者生存率呈负相关。CRIF1在骨肉瘤细胞系中高表达,抑制CRIF1的表达可导致G1/S检查点失活、DNA修复延滞以及线粒体结构功能受损,从而降低骨肉瘤细胞的放射抗性。CRIF1与CDK2存在相互结合作用,放射后二者在细胞核中同步聚集。抑制CRIF1可诱导CDK2放射后入核转运受阻,进而影响CDK2的Thr14和Thr160位点磷酸化水平。抑制CRIF1可导致放射后未完全修复DSBs的细胞通过G1期检查点进入S期,EdU和γH2AX双阳性细胞比率显著增加;还可延滞NBS1 Ser432位点的磷酸化增强,γH2AX的阳性数明显高于对照细胞;最终通过影响G1/S期检查点激活和DNA修复引起细胞凋亡。动物实验证实,抑制CRIF1并联合放疗可显著增加TUNEL阳性细胞数量,导致肿瘤消退。结论体内外研究结果均显示,CRIF1与骨肉瘤的放射抗性密切相关。CRIF1介导的放射后CDK2入核转运和Thr14/Thr160磷酸化可通过促进G1/S期检查点激活和DNA修复参与骨肉瘤的放疗抵抗。该研究有望为寻找放射增敏靶分子,克服骨肉瘤的放疗耐受性提供了新思路。
