Phenotyping and Biobanking Core

项目摘要 青少年节律，奖励和睡眠中心（CARRS）表型分析和生物库核心（核心 B）通过获得具有特定表型的研究对象来支持研究项目 人类和动物项目所需的特性。我们的核心假设是晚睡时间， 睡眠时间短和昼夜节律失调对青少年的皮质边缘功能有不利影响， 进一步增强奖赏敏感性，损害认知控制，并增加物质使用风险。的 协调和深思熟虑的程序，以确保人类的相似表型特征， 动物为这一转化科学计划提供了基础。对于人类研究（项目1和2）， 核心B将对13至15岁的青少年进行系统招募和筛选， 为参与者提供系统性的不同睡眠时间。对于啮齿动物研究，核心B将建立一个育种 和表型分析管道，以提供项目3、4和5所需的动物。核心B还将提供 生物库服务，包括青少年样本的收集、管理和库 人类和青春期HS大鼠来测量分子节律表型，并提供高质量的 为今后的机制研究提供了资料。核心B有助于这一创新的转化研究计划 通过合作开发和实施计划，确保CARRS人的相似表型， 青少年和青少年啮齿动物模型研究。

PROJECT SUMMARY The Center for Adolescent Rhythms, Reward, and Sleep (CARRS) Phenotyping and Biobanking Core (Core B) supports the research projects through the acquisition of research subjects with specific phenotypic characteristics required by the human and animal projects. Our central hypothesis is that late sleep timing, short sleep duration, and circadian misalignment adversely impact cortico-limbic function in adolescents, further enhancing reward sensitivity, impairing cognitive control, and increasing substance use risk. The coordinated and deliberate procedures for assuring analogous phenotypic characteristics in humans and animals provide the foundation for this translational scientific program. For human studies (Projects 1 and 2), Core B will conduct systematic recruitment and screening of adolescents ages 13 through 15 years old to provide participants systematically varied in sleep timing. For rodent studies, Core B will establish a breeding and phenotyping pipeline to provide the animals required for Projects 3, 4 and 5. Core B will also provide biobanking services, including the collection, management, and banking of specimens from adolescent humans and adolescent HS rats to measure molecular rhythm phenotypes and to provide a high-quality repository for future mechanistic studies. Core B contributes to this innovative translational research program by collaboratively developing and implementing plans for assuring analogous phenotypes for CARRS human adolescent and adolescent rodent model studies.
