项目摘要
Project Summary – Project 4
Melanoma is the deadliest form of skin cancer. While significant progress has been made treating melanoma,
drug resistant represents one of the greatest challenges to achieve optimal responses and improve patient
outcomes. Our long-term goal is to understand mechanisms underlying dysregulated signaling and drug
resistance in melanoma to form the pre-clinical basis for improved treatment options. In this project, we are
focusing on a clinical unmet need, the treatment of cutaneous melanomas that are wild-type (WT) for BRAF
(both WT BRAF/WT NRAS and mutant NRAS). MEK-ERK1/2 signaling is activated in WT BRAF melanoma
but the response to MEK inhibitors is poor. Furthermore, immune checkpoint agents elicit responses in only
30-40% of cases and patients who are non-responsive have no effective treatment options. The goals of this
project are to identify drug tolerance mechanisms in subsets of WT BRAF melanomas to provide the basis for
new strategies to improve targeted inhibitor treatments and provide salvage options for melanomas that are
non-responsive to immune checkpoint agents. Our preliminary data indicate that MEK inhibition triggers a
receptor tyrosine kinase-mediated adaptive response in WT/WT melanoma. Based on these data, we
hypothesize that the efficacy of MEK inhibitors will be improved with agents targeting either adaptive ErbB3
responses or epigenetic BET/BRD ‘reader’ proteins, as these epigenetic readers regulate multiple receptor
kinase tyrosine kinase and oncogenic pathways associated with drug resistance. We aim to identify and target
mechanisms underlying enhanced activation of the growth factor receptor, ErbB3, in MEK inhibitor-treated
melanoma. Additionally, we will test the efficacy of BET inhibitor-based combinations to mitigate
stress/therapy tolerance mechanisms and develop optimal combinatorial approaches to offset drug resistance.
We will primarily focus on WT/WT melanoma but, where possible, extend our observation to mutant NRAS
melanoma. To achieve these goals, we will leverage our unique genetically and clinically annotated models
including in vitro 3D/T cell autologous organoids, immune checkpoint inhibitor-resistant patient-derived
xenografts and syngeneic mouse models. Through synergistic interactions with other projects and cores in the
P01, we will identify mechanisms underlying tumor cell intrinsic and stromal-mediated adaptive responses to
targeted and immune therapy and inform future combinatorial targeted/epigenetic inhibitor strategies that can
be translated into effective treatments. This project meets the NCI mission by conducting research into the
treatment of the deadliest form of skin cancer.
项目摘要-项目4
黑色素瘤是最致命的皮肤癌。虽然治疗黑色素瘤已经取得了重大进展,
耐药性是实现最佳反应和改善患者预后的最大挑战之一。
我们的长期目标是了解信号失调和药物依赖的潜在机制。
黑色素瘤耐药性的研究,以形成改善治疗方案的临床前基础。在这个项目中,我们
专注于临床未满足的需求,治疗BRAF野生型(WT)皮肤黑色素瘤
(both WT BRAF/WT NRAS和突变型NRAS)。 MEK-ERK 1/2信号在WT BRAF黑素瘤中被激活
但对MEK抑制剂的反应很差。 此外,免疫检查点试剂仅在小鼠中引起应答。
30- 40%的病例和无应答的患者没有有效的治疗选择。 这个的目标
该项目旨在确定WT BRAF黑色素瘤亚群的药物耐受机制,为
改善靶向抑制剂治疗并为黑色素瘤提供挽救选择的新策略,
对免疫检查点试剂无应答。 我们的初步数据表明,MEK抑制触发了一个
WT/WT黑色素瘤中受体酪氨酸激酶β介导的适应性反应。 根据这些数据,我们
假设靶向适应性ErbB 3的药物将提高MEK抑制剂的功效
表观遗传BET/BRD“阅读器”蛋白,因为这些表观遗传阅读器调节多个受体
激酶酪氨酸激酶和致癌途径与耐药相关。我们的目标是识别和靶向
在MEK抑制剂处理的大鼠中,生长因子受体ErbB 3活化增强的潜在机制
黑素瘤 此外,我们将测试BET抑制剂-基于维生素C的组合的功效,以减轻
压力/治疗耐受机制和开发最佳组合方法来抵消耐药性。
我们将主要关注WT/WT黑色素瘤,但在可能的情况下,将我们的观察扩展到突变型NRAS
黑素瘤 为了实现这些目标,我们将利用我们独特的遗传和临床注释模型
包括体外3D/T细胞自体类器官,免疫检查点抑制剂-抗肿瘤患者-肿瘤衍生的
异种移植和同系小鼠模型。通过与其他项目和核心的协同作用,
P01,我们将确定肿瘤细胞内在和基质介导的适应性反应的机制,
靶向和免疫治疗,并告知未来的组合靶向/表观遗传抑制剂策略,
该项目通过对这些疾病的研究来满足NCI的使命。
