The NIEHS Superfund Research Program (SRP) is hosting a Risk e-Learning webinar series focused on SRP-funded data science projects that are enhancing the integration, interoperability, and reuse of data. With these supplements, the SRP encourages data sharing among its grantees to accelerate scientific discoveries, stimulate new collaborations, and increase scientific transparency and rigor.

The third and final session will feature SRP-funded researchers collaborating to combine omics (e.g., genomics, proteomics) data within and across model organisms as well as studies in human populations. We will also hear from The Global Alliance for Genomics and Health about their work to incorporate semantic data models for sharing of genomic data to align with environmental health research.

Monica Munoz-Torres, Ph.D., Anne Thessen, Ph.D., and Melissa Haendel, Ph.D., will present on the Global Alliance for Genomics and Health and discuss harmonizing and sharing phenotypes across organisms for diagnostics and mechanism discovery. Describing phenotypes in a way that is as computable as sequences has been a major barrier to biomedicine. Within the Global Alliance for Genomics and Health, members of the Monarch Initiative have led the creation of the Phenopacket standard. Phenopackets are computable phenotypic profiles encoded using ontologies, which can be used to relate a patient’s phenotypic profile to model organisms and thereby improve diagnostics, mechanism discovery, and integration with environmental health data. Melissa Haendel, Ph.D., is the Chief Research Informatics Officer at University of Colorado Anschutz Medical School, the director of the Center for Data to Health (CD2H), and an elected Fellow of the American Medical Informatics Association. Monica Munoz-Torres, Ph.D., is a Program Manager in the Translational and Integrative Sciences Lab (TISLab). Anne Thessen, Ph.D., is a Semantics Engineer in the TISLab.

Mark Hahn, Ph.D., Senior Scientist at Woods Hole Oceanographic Institution and researcher with the Boston University SRP Center, and Adam Labadorf, Ph.D., Assistant Professor at Boston University, will describe the integration of diverse genome-scale data sets to obtain a better understanding of how genetic variation influences sensitivity and resistance to hazardous chemicals. The research builds on research on the genetic mechanisms underlying evolved resistance to polychlorinated biphenyls and polycyclic aromatic hydrocarbons in Atlantic killifish (Fundulus heteroclitus) populations living at Superfund sites. They will also describe a new JBrowse instance that integrates multiple genomic data sets, facilitating comparison of genetic variation among killifish populations; they will discuss the potential to expand this platform for cross-species comparisons (e.g., zebrafish, human).

Christian Powell, graduate student at the University of Kentucky, will focus on the Metabolomics Workbench which is a public scientific data repository consisting of experimental data and metadata from metabolomics studies collected from mass spectroscopy and nuclear magnetic resonance analyses. In order to keep up with the ever-evolving state of the Metabolomics Workbench repository, the open source mwtab Python package has been updated to mirror the changes in the mwTab file format and now contains enhanced file validation features, methods for utilizing the Metabolomics Workbench REpresentational State Transfer (REST) interface, and additional features for parsing metabolite data and metadata from repository entries. All of these resources are available through an updated Command Line Interface (CLI) and as a Python application programming interface (API). The mwtab package continues to strive to promote the most FAIR utilization of the Metabolomic Workbench repository, coevolving with and continuing to improve alongside the repository.

Andres Cardenas, Ph.D., M.P.H., Assistant Professor of Environmental Health Sciences at the University of California, Berkeley, and Anne Bozack, Ph.D., M.P.H., postdoctoral fellow in the Cardenas Lab at the University of California, Berkeley, will discuss arsenic epigenetics META: Meta-analysis of Epigenome Data on Arsenic. Epigenome-wide association studies (EWAS) of environmental exposures are commonly restricted to single populations with small sample sizes, and comparison across EWAS has been limited by methodological differences. To address these limitations, they developed a two-step process of (1) harmonized data processing and analysis and (2) meta-analysis to combine results across EWAS. The researchers leveraged data from epidemiological studies of arsenic-exposed populations in Chile and Bangladesh, including DNA methylation measured in different tissue types (i.e., PBMCs and buccal cells) and using different platforms (i.e., the 850K and 450K microarrays), to identify arsenic-related DNA methylation signatures.
