Nematode Metabolomics

The past few years have seen a surge of interest in using NMR-spectroscopic techniques for characterizing complex metabolite mixtures. The Schroeder lab has developed new computational and statistical methods to identify individual components in complex metabolite samples and determine their biological function(s). This approach accelerates the pace of natural products research because it reduces the need for chromatographic fractionation and enables the identification of previously inaccessible small molecules, for example compounds that are prone to chemical decomposition and thus cannot be isolated. In particular, comparative metabolomics, based on statistical analyses of NMR spectra and HPLC-MS data has proven highly effective at identifying novel and known metabolites that correlate with changes in genotype or phenotype.

The nematode Caenorhabditis elegans is one of the most important model organisms for biomedical research, because of its experimental tractability and because many of its physiological pathways show strong analogies to corresponding pathways in humans. In addition, discoveries in C. elegans are relevant for human health, given that more than 2 billion people are currently infected with parasitic nematodes, which cause devastating disease and disability. Understanding chemical signaling in C. elegans will aid in developing new approaches toward control and eradication of nematode-derived disease. Lastly, C. elegans research is highly relevant to the agricultural industry since nematode pests are a significant source of crop loss.

The Schroeder lab aims to complement the highly developed genomics and proteomics resources for C. elegans with a comprehensive structural and functional characterization of its metabolome. This effort has revealed that small molecules play important roles in C. elegans endocrine and exocrine signaling, specifically in key pathways regulating lifespan, development, and metabolism. Two-dimensional NMR spectroscopy permits the comparison of complex metabolite samples derived from different C. elegans mutant strains to identify and characterize compounds whose biosynthesis is strongly up- or down-regulated as a result of a specific mutation. The Schroeder lab has selected a number of C. elegans mutant strains whose phenotypes suggest a defect in small-molecule signaling that affect conserved pathways regulating lifespan, development, and fat metabolism. These studies have identified several series of novel small molecules that delay ageing, control sexual attraction, or play important roles in C. elegans development. To validate the biological function of these novel small molecules, samples of the identified compounds are synthesized and used for chemical genetic screens to determine effects on lifespan, development, and fat metabolism. Compounds that show activity in wild-type C. elegans are subjected to additional assays with mutant or RNAi strains representative of key genetic pathways related to ageing and development.

Of particular interest is a class of molecules called ascarosides, which are synthesized by C. elegansand many other nematodes, but have not yet been detected outside of nematodes. Ascarosides are often active at exceedingly low concentrations, and affect a number of behavioral and developmental processes in nematodes. They have the potential to be useful for controlling pathogenic nematodes, including nematodes that cause human and animal disease, as well as pathogens of economically important crop plants. They may also be useful for attracting beneficial nematodes, for example entomopathogenic nematodes that kill insect pests. Nematodes have co-evolved with their hosts for millions years and appear to evade immune surveillance, suggesting that these parasites actively modulate their host’s immune system. Experiments to characterize effects of ascarosides on animal and plant immune responses are currently under way.

Research Overview

Please see our Group Website for recent news and publications, research updates, and teaching.

Our research is directed at characterizing structures and biological functions of biogenic small molecules (BSM’s). BSM’s play important roles in most biological processes, and detailed knowledge of their chemical structures and their interactions with other biomolecules is essential for advancing our molecular understanding of life. BSM’s regulate development and immune responses in plants and animals, and serve important functions in interactions of different organisms with each other. As a result, an organism’s metabolome essentially comprises a collection of small molecules with potentially useful affinities for specific molecular targets. Not surprisingly, BSM’s constitute the most important source of lead structures for drug development.

Compared to template-derived biological macromolecules such as proteins and nucleic acids, BSM’s are chemically much more diverse and correspondingly present great analytical challenges. As a result, genomic and proteomic knowledge has not yet been complemented by a comprehensive characterization of structures and functions of metabolomes, presenting one of the most significant barriers toward advancing our understanding of biological pathways.

The Schroeder lab aims to help close this knowledge gap by developing approaches for a more systematic structural and functional characterization of BSM’s. Usually, BSM’s occur as – often minor – components of a more or less complex biological matrix, comprising a large number of BSM’s and other biomolecules. Traditional approaches for the characterization of BSM’s such as HPLC-MS or activity-guided fractionation have distinct disadvantages that severely limit their applicability. Our aims is to develop NMR spectroscopy-based approaches that complement or enhance traditional methodology by enabling detailed characterization of BSM’s in complex biological samples, with regard to both chemical structure and biological function.

Based on NMR-spectroscopic methodology we have engaged in a comprehensive effort to characterize structures and functions of the metabolome (the entirety of all BSM’s) produced by the model organism Caenorhabditis elegans, focusing on several newly discovered compounds that control development, and ultimately lifespan. In addition we have started a project directed at investigating the chemical ecology of microorganisms in search of leads for new antibiotics. Complementing our interests in analytical chemistry, we pursue development of efficient syntheses for newly identified compounds with particular biological significance.
