We request DFG funding for a Molecubes small animal PET/CT (ß- und X-Cube combination, "benchtop PET CT integrated platform"), a small labspace molecular imaging device with each one component for PET and CT.Our research is focused on translational theranostics, based on small radioligands for diagnosis and treatment of cancer. Translational research aims at: Prostate cancer is one of the leading causes of cancer-related death among men worldwide. We developed a mouse model of prostate cancer with high expression levels of PSMA. Small animal PET/CT will be used to assess alternative routes of tracer application in mice. We further aim to evaluate improved efficacy through radioligand drug combination therapy with VE-822 and Enzalutamide. Fibroblast activation protein (FAP) is expressed at high levels in fibroblast-associated malignancies. Chinolin-based radiolabeled inhibitors of FAP (FAPI) can be applied to accurately assess extent of breast cancer, pancreatic cancer, or ENT tumors using positron-emission-tomography (PET). We will develop a mouse model of human cancer to test various radiolabeled FAP-inhibitors for their biodistribution and accuracy. In collaboration with other University institutions, we will use small animal PET/CT imaging to assess immunstimulatory calciumphosphate nanoparticles, avatar-models of lung cancer, murine melanoma models, and off-line dose assessments for proton beam therapy.

我们请求DFG为Molecube小动物PET/CT(？？和X-Cube组合，“台式PET CT集成平台”)提供资金，这是一个小型实验室分子成像设备，每个组件用于PET和CT。我们的研究集中在翻译治疗方面，基于用于癌症诊断和治疗的小放射性配体。翻译研究的目标是：前列腺癌是全球男性癌症相关死亡的主要原因之一。我们建立了一种PSMA高表达的前列腺癌小鼠模型。小动物PET/CT将被用来评估在小鼠身上应用示踪剂的替代途径。我们进一步的目标是评估通过放射配基药物与VE-822和恩扎鲁胺联合治疗改善的疗效。成纤维细胞激活蛋白(FAP)在成纤维细胞相关的恶性肿瘤中高水平表达。奇诺林标记的FAP抑制物(FAPI)可用于正电子发射断层扫描(PET)准确评估乳腺癌、胰腺癌或耳鼻咽喉肿瘤的程度。我们将开发一种人类癌症的小鼠模型，以测试各种放射性标记的FAP抑制剂的生物分布和准确性。与其他大学机构合作，我们将使用小动物PET/CT成像来评估免疫刺激的磷酸钙纳米颗粒、肺癌的替身模型、小鼠黑色素瘤模型，以及质子束治疗的离线剂量评估。
