项目摘要
This proposal requests partial support for the FASEB Summer Research Conference on Dynamic DNA
Structures in Biology, which will be held July 15-20, 2018, in Olean, NY.
For decades after its discovery, DNA was believed to be a rigid, right-handed double helix. It is
now appreciated, however, that DNA is highly dynamic molecule and can assume an enormous variety
of conformations such as cruciforms, left-handed helices, three- and four-stranded helices, and slip-
stranded configurations. Repetitive DNA sequences, which are overrepresented in genomic DNA, are
particularly prone to such structural transitions. The transient denaturation of the double helix that
occurs during most DNA transactions (transcription, replication and recombination) also promotes
dynamic transitions in DNA structure. The cellular environment can also influence structure formation.
Studies have confirmed that structure-prone DNA sequences are central to the normal functioning of
the genome. Transitions in DNA structure are important for regulating the activation of transcription and
the specialized recombination responsible for immunoglobulin class switching. Unscheduled transitions,
however, can have pathological consequences. The expansion of structure-prone repeats underlies
more than thirty hereditary neurological and developmental diseases in humans and dynamic DNA
structures are associated with genome rearrangements observed in many human cancers.
The long-term objective of this Conference is to enhance our understanding of how dynamic DNA
structures form, how they contribute to normal genetic processes and how they promote pathological
outcomes such as genetic disease, cancer and aging. Our aims are to explore DNA structural
transitions, to define novel mechanisms that promote formation and resolution of dynamic DNA
structures, to stimulate collaborations, and to foster the long-term development of this important area by
promoting participation of junior scientists. To that end, we will convene ~100 participants for five
intense and highly interactive days of science. The program will include two opening keynote talks,
eight morning/evening scientific sessions and informal afternoon poster sessions. New this year will be
a session on genome editing. In addition, another new feature will be to involve early career scientists
in the planning and content of “meet the speaker” and career workshop discussions at the conference.
One third of the talks will be chosen from submitted abstracts, with preference given to trainees and
junior investigators. For many trainees, this will be the first opportunity to give a talk at a scientific
meeting. The significance and strength of this Conference is that it uniquely brings together
investigators with a common focus on dynamic DNA transitions, but who have highly varied
backgrounds, expertise and experimental approaches.
该提案要求为FASEB动态DNA夏季研究会议提供部分支持
生物学结构,将于2018年7月15日至20日在纽约州奥利安举行。
在DNA被发现后的几十年里,人们一直认为它是一种刚性的右旋双螺旋结构。是
然而,现在认识到,DNA是高度动态的分子,可以呈现出巨大的多样性

本次会议的长期目标是加强我们对动态DNA如何

结果,如遗传疾病,癌症和衰老。我们的目标是探索DNA结构

促进青年科学家的参与。为此,我们将召集约100名与会者,
紧张和高度互动的科学天。该计划将包括两个开幕式主题演讲,
8个上午/晚上的科学会议和下午的非正式海报会议。今年新将是

三分之一的讲座将从提交的摘要中选出,优先考虑学员,

会议本会议的重要性和力量在于,它独特地汇集了
研究人员共同关注动态DNA转换,但他们有着高度不同的
背景、专业知识和实验方法。
