项目摘要
Epidemiological studies indicate that chemotherapy can increase the chance of metastasis in a subset patients,
but the underlying mechanism remains unclear because of a lack of relevant experimental models. The goal of
this proposal is to elucidate the impact of chemotherapy on metastatic relapse with a tissue-engineered
metastasis model that can capture metastatic niche evolution with a high level of molecular and cellular detail.
Inspired by the recent discovery of the pre-metastatic niche (PMN) in major metastatic organs, we have
developed a bone marrow stromal cell–seeded microfabricated porous hydrogel scaffold that creates a richly
vascularized proinflammatory microenvironment when it is subdermally implanted in a mouse. This implantable
PMN model has been shown to attract and support the engraftment and growth of circulating tumor cells and
can be serially implanted in syngeneic naive mice for long-term studies. The semitransparent materials of the
implant are compatible with quantitative imaging analysis via multiple imaging modalities including multiplex
immunohistostaining, CLARITY-based optical sectioning of entire scaffolds, and intravital imaging via a skinfold
window chamber.
Our central hypothesis is that tissue inflammation and remodeling induced by chemotherapy activates
dormant disseminated tumor cells and causes them to migrate and form in situ clusters as a function of cell
number. Forming clusters could allow the cells to overcome microenvironmental regulation and regain an
aggressive phenotype. We propose three specific aims: In Aim 1, we will generate subcutaneous and hepatic
PMN models in a MMTV-PyMT female mouse and demonstrate the long-term evolution of metastatic niche by
serially transplanting early metastatic niche established in primary mice to secondary syngeneic FVB mice. For
this purpose, we will generate MMTV-Luc2-PyMT mice that allow non-invasive long-term bioluminescent
monitoring of metastatic relapse. In Aim 2, we will use the techniques verified in Aim 1 to observe the effect of
chemotherapy with doxorubicin on the metastatic process in serially implanted bone marrow and liver PMN
models. In Aim 3, we will apply the established algorithm to measure potency to determine if adjuvant therapy
with anti-inflammatory (anakinra) or anti-macrophage (clodronate) drugs reduces doxorubicin-induced
metastatic relapse and will look at the effect of adjuvant timing. The proposed research is significant because it
has the potential to facilitate the development of better therapeutic regimens that can eliminate active residual
tumor cells without activating dormant disseminated tumor cells, and this would significantly improve long-term
metastasis prevention.
流行病学研究表明,在大多数患者中,化疗可能会增加肿瘤转移的风险。
但其基本机制仍不清楚,因为目前还缺乏相关的实验模型。这是中国的主要目标。
这项新的提案旨在通过组织工程来阐明化疗对转移和复发的主要影响。
转移模型认为,它可以通过高水平的分子生物学和细胞生物学细节来更好地捕捉转移的利基生物的进化。
最近在一些主要的转移性器官中发现了转移前的利基细胞(PMN),受此启发,我们已经有了。
开发出了一种新的骨髓基质细胞种植的、微细加工的、多孔的水凝胶支架材料,它创造了一个丰富的支架。
血管化的促炎和微环境,当它被移植到小鼠的皮下时。这是可植入的。
PMN的模型已经被证明能够吸引和支持循环中的肿瘤细胞的移植和生长。
可以将其连续移植到同基因的幼小鼠体内,用于长期的临床研究。这是目前最先进的半透明材料。
植入物与通过包括多路复用器在内的多种成像方式进行的定量成像和分析完全兼容。
免疫组织化学染色,基于清晰度的光学切片技术,对整个支架进行扫描,并通过皮肤褶皱进行活体内成像。
窗户和房间。
我们的中心假说是,化疗后诱导的组织炎症反应和血管重塑被激活。
休眠和播散的肿瘤细胞是导致它们迁移和在原位形成簇的原因,这是细胞的一项重要功能。
数量。通过形成新的集群,可以使这些细胞能够更好地克服微环境监管问题,并重新获得更多的利润。
积极的表型。我们将提出三个具体的治疗目标:在第一个目标中,我们将不会产生皮下组织和肝脏肿瘤。
PMN的模型展示了一种MMTV--PYMT的雌性小鼠模型,并展示了这种转移的利基动物的长期生物进化过程。
连续移植早期转移的FVB小鼠,建立了在初级小鼠和继发性同基因FVB小鼠中建立的利基环境。
出于这个目的,我们将创造出一种MMTV-Luc2-PyMT小鼠模型,使其能够实现非侵入性的长期生物发光。
监测肿瘤转移和复发的情况。在目标2中,我们将继续使用在目标1中验证的新技术来观察其近期效果。
化疗结束后,阿霉素继续进行转移,并连续植入骨髓和肝脏中的PMN。
模型。在Aim 3中,我们将继续应用之前建立的算法来测量其效力,以确定是否需要辅助治疗。
有了抗炎药(Anakinra)或抗巨噬细胞药(Clodronate),这些药物可以减少阿霉素诱导的阿霉素。
转移性肿瘤的复发和复发将不会考虑辅助治疗时机的临床效果。但是,新提出的研究计划是非常重要的,因为它。
已经提供了潜在的机会,以进一步促进更好的治疗方案的开发,这些方案可以很好地消除活跃的和残留的疾病。
如果不激活处于休眠状态和已扩散的肿瘤细胞,那么从长远来看,这种治疗将显著改善。
转移和预防。
