摘要
对微生物组的重新关注已经产生了许多关于细菌的作用的有趣发现。
人类生物学和疾病中的共生体。然而,大多数这些发现是相关的和关联的;
在分子机制水平上了解微生物-宿主相互作用。 典型方法
解决这个问题的方法是一次性的努力,试图找到一个单独的分子负责的表型
感兴趣 在这里,我们建议通过系统地研究一个最具体的
微生物群对人类生物学的贡献:来自肠道的“前100名”分子,按丰度计算
社区 这些分子在个体间的浓度差异很大,可以在宿主体内积累,
在血液循环中,它们的浓度与典型的小分子药物的浓度相匹配或超过。
我们在这里提出的工作-确定产生前100种细菌的细菌种类,并确定
负责的基因-将是创造完全指定分子的能力的第一步
肠道群落的输出(哪些分子产生,哪些分子不产生),我们将试验这一过程
在目前的项目中。
我们每天都接触到的几十种高浓度分子的集合体很可能是一种
人类生物学和疾病的主要驱动力。想象一个未来,在这个未来,
将拥有一个“重新编程”(合成)的肠道群落,其分子输出已被优化,
疾病的治疗和预防。
天然产物发现和微生物组研究领域由基因组学主导,

英文摘要
Abstract
Renewed interest in the microbiome has yielded numerous intriguing findings about the role of bacterial
symbionts in human biology and disease. However, most of these findings are correlative and associative;; little
is known about microbiota-host interactions at the level of molecular mechanism. Typical approaches to
address this problem are one-off efforts that attempt to find an individual molecule responsible for a phenotype
of interest. Here, we propose to upend this paradigm by systematically studying one of the most concrete
contributions of the microbiota to human biology: the ‘top 100’ molecules, by abundance, from the gut
community. These molecules vary widely in concentration among individuals, can accumulate in host
circulation, and are present at levels that match or exceed the concentration of a typical small molecule drug.
The work we propose here – to determine the bacterial species that produce each of the top 100, and identify
the genes responsible – will be the first step toward creating a capability to completely specify the molecular
output of the gut community (which molecules are produced, and which others are not), a process we will pilot
in the current project.
This ensemble of dozens of high-concentration molecules – to which we are exposed daily – is likely to be a
major driver of human biology and disease. It is not unreasonable to imagine a future in which every human
will harbor a ‘reprogrammed’ (synthetic) gut community whose molecular output has been optimized for
disease treatment and prevention.
The fields of natural product discovery and microbiome research are dominated by genomics-driven
approaches. The solution we propose here runs entirely counter to this trend: we will start with 1) an empirical
approach that is, in essence, old-fashioned Bergey’s-style microbiology outfitted with state-of-the-art analytical
chemistry. Using the rich information we derive from empirical metabolic profiling, we will then 2) use genetics
and biochemistry to identify the genes responsible for synthesizing the top 100, 3) use this information to
devise a computational algorithm that can predict metabolic output directly from metagenomic sequence data,
and 4) test our predictions using simple synthetic communities. Our data will create a rich metabolic map of the
top 100, and will enable the construction of transplant-ready synthetic communities that produce custom
cocktails of desired molecules (and do not produce undesired molecules).
