SUMMARY In the study of disease, the polygenic factors that lead to genetic adaptation in species, essentially who will be asymptomatic while under environmental stressors, mostly remain undiscovered. Without a comparative understanding of these unique features by cell type, that evolution has preserved, our efforts to more broadly implement precision medicine will be limited in multiple phenotypes. One of the most promising applications of evolutionary medicine has been the use of divergent animal models to deconstruct and uncover fundamental concepts of biological organization in great detail. The Mexican cavefish, Astyanax mexicanus provides a rapidly growing model system to apply principles of evolutionary medicine to study trait variation. We have implemented a toolbox of genetic tools that allow for functional interrogation of various traits in the Mexican cavefish, but key resources are missing. This model species consists of surface and cavefish populations that possess natural trait differentiation, often displaying genetic adaption associated with environmental change, without impacting health or longevity. The objectives of our studies are to generate three tiers of community requested resources: high-quality surface and cavefish genome assemblies, using powerful single-cell sequencing technology a cell atlas with differentiating gene expression data sets and targeted gene reporter constructs coupled with a spatial understanding of their gene regulatory effects. This compendium of resource data and methodology can serve a large community wishing to test various hypotheses of adaptation in this species and others. Our proposed research objectives are significant in that they will contribute comparative gene networks that reveal novel differences with a growing assemblage of gene candidates for human diseases.

总结 在疾病的研究中，多基因因素导致物种的遗传适应，基本上谁都会无症状 而在环境压力下，大多数仍然未被发现。如果没有对这些独特的 细胞类型的特征，进化已经保存下来，我们更广泛地实施精准医学的努力将受到限制 多种表现型。进化医学最有前途的应用之一是使用不同的 动物模型，以解构和揭示生物组织的基本概念非常详细。墨西哥 墨西哥丽脂鲤提供了一个快速生长的模型系统，将进化医学的原理应用于 研究性状变异。我们已经实现了一个遗传工具的工具箱，允许对各种性状进行功能性询问 墨西哥洞穴鱼，但关键资源缺失该模式物种由表层鱼和洞穴鱼种群组成， 具有自然的性状分化，通常表现出与环境变化相关的遗传适应， 影响健康或寿命。我们研究的目标是产生三个层次的社区要求的资源： 高质量的表面和cavefish基因组组装，使用强大的单细胞测序技术， 区分基因表达数据集和靶向基因报告构建体， 基因调控效应这个资源数据和方法的概要可以为希望测试的大型社区提供服务 关于这个物种和其他物种适应环境的各种假说。我们提出的研究目标是重要的，因为它们 将有助于比较基因网络，揭示新的差异与越来越多的基因候选人组合， 人类疾病。
