We introduce and describe the Breast Cancer and the Environment Research Centers (BCERC), a research network with a transdisciplinary approach to elucidating the role of environmental factors in pubertal development as a window on breast cancer etiology. We describe the organization of four national centers integrated into the BCERC network.
Investigators use a common conceptual framework based on multiple levels of biologic, behavioral, and social organization across the life span. The approach connects basic biologic studies with rodent models and tissue culture systems, a coordinated multicenter epidemiologic cohort study of prepubertal girls, and the integration of community members of breast cancer advocates as key members of the research team to comprise the network.
Relevant literature is reviewed that describes current knowledge across levels of organization. Individual research questions and hypotheses in BCERC are driven by gaps in our knowledge that are presented at genetic, metabolic, cellular, individual, and environmental (physical and social) levels.
As data collection on the cohort, animal experiments, and analyses proceed, results will be synthesized through a transdisciplinary approach.
Center investigators are addressing a large number of specific research questions related to early pubertal onset, which is an established risk factor for breast cancer. BCERC research findings aimed at the primary prevention of breast cancer will be disseminated to the scientific community and to the public by breast cancer advocates, who have been integral members of the research process from its inception.
我们介绍并描述乳腺癌与环境研究中心(BCERC),这是一个采用跨学科方法的研究网络,旨在阐明环境因素在青春期发育中的作用,以此作为了解乳腺癌病因的一个窗口。我们描述了纳入BCERC网络的四个国家中心的组织架构。
研究人员使用一个基于生命全周期中生物学、行为学和社会组织多个层面的通用概念框架。该方法将基础生物学研究与啮齿动物模型及组织培养系统相联系,对青春期前女孩进行一项多中心协调的流行病学队列研究,并将乳腺癌倡导者群体成员纳入研究团队作为关键成员,共同构成该网络。
对描述各组织层面现有知识的相关文献进行综述。BCERC中的各个研究问题和假设是由我们在基因、代谢、细胞、个体以及环境(物理和社会)层面所存在的知识空白驱动的。
随着队列研究、动物实验及分析的数据收集工作的推进,结果将通过跨学科方法进行综合。
中心研究人员正在解决大量与青春期过早开始相关的具体研究问题,青春期过早开始是已确定的乳腺癌风险因素。BCERC旨在预防乳腺癌的研究结果将由乳腺癌倡导者传播给科学界和公众,这些倡导者从研究开始就一直是研究过程中不可或缺的成员。
