项目摘要
Project Summary
The microenvironment plays a unique role in the development of melanoma, which arises in the skin. The skin
displays externally visible signs of aging, such as decreased elasticity and a loss of collagen integrity. Much
work has focused recently on how changes in collagen can affect tumor metastasis, both biomechanically and
biochemically. Data from several groups indicate that the cross-talk between stromal fibroblasts and
transformed melanocytes is important for invasion, melanoma growth, and even therapy resistance. Our
proteomics analyses indicate that factors used to crosslink collagen, such as HAPLN1 are secreted by young,
but not aged dermal fibroblasts, and Wnt5A is secreted by aged, but not young fibroblasts. The interplay
between these molecules may contribute to age-related changes in collagen integrity. We hypothesize that
changes regulated by age-related alterations in the extracellular matrix (ECM) initiate or promote a pro-
metastatic program, and impact therapy resistance.
We will query the contribution of aged skin biochemical and architectural contributions in governing
melanoma’s metastatic progression as well as resistance to targeted therapy. We propose an alternate theory
of matrix stiffness that hypothesizes that increasing stiffness will have a non-linear effect on metastatic
progression, and therapy resistance. We will use pathophysiologically relevant in vitro 3D stromal systems (3D
skin reconstructions), animal models of melanoma, a novel simultaneous multi-channel immunofluorescent
analysis (SMIA) of formalin-fixed and paraffin embedded (FFPE) human tissue cohorts in combination with a
customized new software written for the bulk analysis and acquisition of SMIA-generated images, single
molecule RNA imaging coupled with high-throughput single cell imaging and sequencing, all of which will feed
back into an increasingly intricate mathematical modeling for improved understanding and better patient
personalized (i.e., metastatic and efficacy of drug treatment) prediction capabilities. We expect our data will
reveal a synergistic picture of the mechanochemical interactions between the aged microenvironment and
singular tumor cells that the individual approaches could not have deciphered.
This team project involves experts in the biology of melanoma metastasis, Wnt signaling and aging
(Weeraratna), single cell RNA systems biology (Raj), tumor-stromal interactions and digital imaging
quantitative analyses (Cukierman) and computational and mathematical predictive modeling (Shenoy).
项目摘要
微环境在皮肤中产生的黑色素瘤的发育中起着独特的作用。皮肤
显示外部可见的衰老迹象,例如弹性降低和胶原蛋白完整性的丧失。很多
最近的工作重点是胶原蛋白的变化如何影响肿瘤转移,无论是生物力学和
生化。来自几个组的数据表明,基质成纤维细胞和
转化的黑素细胞对于侵袭,黑色素瘤生长甚至耐药性很重要。我们的
蛋白质组学分析表明,用于交叉链接胶原蛋白(例如HAPLN1)的因素分析是由Young分泌的
但不是老化的皮肤成纤维细胞,Wnt5a被老化,但不是年轻的成纤维细胞分泌。相互作用
这些分子之间可能导致胶原蛋白完整性与年龄相关的变化。我们假设这一点
受年龄相关的细胞外基质(ECM)的变化所调节的变化,或促进促进
转移计划和影响治疗抗性。
我们将询问老年皮肤生化和建筑贡献的贡献
黑色素瘤的转移性进展以及对靶向疗法的抵抗力。我们提出了另一种理论
矩阵刚度的假设,即增加刚度将对转移产生非线性影响
进展和耐药性。我们将使用与病理生理相关的体外3D基质系统(3D)
皮肤重建),黑色素瘤动物模型,一种新型的同时多通道免疫荧光。
福尔马林固定和石蜡嵌入(FFPE)人体组织队列的分析(SMIA)与A结合
定制的新软件为SMIA生成的图像的批量分析和获取,单个
分子RNA成像,加上高通量单细胞成像和测序,所有这些都将进食
回到越来越复杂的数学建模,以提高理解和更好的患者
个性化(即药物治疗的转移性和有效性)预测能力。我们希望我们的数据将
揭示了老化的微环境与
单个接近的奇异肿瘤细胞无法解剖。
该团队项目涉及黑色素瘤转移,WNT信号和衰老生物学专家
(weeraratna),单细胞RNA系统生物学(RAJ),肿瘤 - 层相互作用和数字成像
定量分析(Cukierman)和计算和数学预测建模(Shenoy)。
