Genetically Engineered Mouse Models for TMEN Research

核心B将提供持续的黑色素瘤小鼠资源，这些黑色素瘤表达 BRAF*，包括对BRAF敏感或耐药的肿瘤活检组织。的综合实力 这个核心在于与A核心中人类黑色素瘤的平行样本相互作用和交叉， 提供具有肿瘤微环境特异性的遗传元素的跨物种三角测量 表型效应。这个核心不仅将提供一组BRAF*小鼠(iBIP和M3)黑色素瘤组织 在基线、治疗后和复发时收集的衍生细胞系，但也有能力 在体外设计新的等位基因并进行临床前治疗研究。有免疫力的人 IBIP黑色素瘤的背景和自然肿瘤微环境环境为其带来了一个关键特征 土门中心。

Core B will provide a constant resource of mice harboring melanomas that express BRAF*, including pairs of tumor biopsies that are sensitive or resistant to BRAFi. The integrative power of this core lies in interacting and intersecting with parallel samples from human melanomas in Core A, providing cross-species triangulation of genetic elements that confer tumor microenvironment-specific phenotypic effects. This core will provide not only a bank of Braf* mouse (iBIP and M3) melanoma tissues and derivative cell lines collected at baseline, post-treatment and upon relapse, but also capability to engineer new alleles ex vivo and perform preclinical therapeutic studies. The immunocompetent background and natural tumor microenvironment setting of IBIP melanomas bring a key feature to this TMEN center.
