Chemical modifications of protein, DNA and RNA nucleoside moieties play critical roles in regulating gene expression. Emerging evidence suggests RNA modifications have substantive roles in multiple basic biological processes. Epitranscriptomics can be defined as the aggregate suite of functional biochemical modifications to the transcriptome within a cell. Recent studies in yeast, Drosophila, rodent and human models demonstrate that stressors can induce RNA modifications, with specific reprogramming of some regulatory RNAs. The NIEHS seeks to solicit innovative, mechanistic research applications that are focused on how environmental exposures are associated and involved with the functional activities of RNA modifications and pathways that may be modified or misregulated, associated with adverse health outcomes and/or be useful as biomarkers of exposure and/or exposure-induced pathologies. The study of functional chemical RNA modification has identified important emerging roles in cellular regulation and gene expression. However, the impact of environmental exposures on functional RNA modifications has been relatively understudied and may present a new mechanism for enhanced understanding the relationships between exposures and the development of complex human diseases. The NIEHS will use the R01 mechanism to support hypothesis driven research using approaches that incorporate principles of toxicology with RNA modification biological and/or chemical expertise and utilizes state of the art technologies.

The reproducibility and comparability of dietary supplement research is enhanced through rigorous analytical characterization of key experimental materials. The publication of analytical methods which have been thoroughly validated for specific, precise, accurate, and sensitive quantitative determination of chemical constituents of dietary supplements therefore makes critical contributions to the rigor and reproducibility of biomedical research. This FOA will build on existing NIH awards to support the performance and publication of formal single-laboratory validation studies of relevant quantitative analytical methods. The methods proposed for validation must be used to identify and quantify chemical constituents (active or marker chemical compounds, adulterants, contaminants) or metabolites thereof in experimental reagents, raw materials, and/or clinical specimens (for example urine or plasma samples). Methods must have been developed or utilized in fulfillment of the active parent grants specific aims. Candidate constituents for quantitative method validation studies may include (but are not limited to): phytochemicals, nutrients, and potentially deleterious substances such as pesticides and mycotoxins. Multi-laboratory validation studies will not be supported through this FOA.

The purpose of this Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative is to encourage applications that will develop and validate novel tools to facilitate the detailed analysis of complex circuits and provide insights into cellular interactions that underlie brain function. The new tools and technologies should inform and/or exploit cell-type and/or circuit-level specificity. Plans for validating the utility of the tool/technology will be an essential feature of a successful application. The development of new genetic and non-genetic tools for delivering genes, proteins and chemicals to cells of interest or approaches that are expected to target specific cell types and/or circuits in the nervous system with greater precision and sensitivity than currently established methods are encouraged. Tools that can be used in a number of species/model organisms rather than those restricted to a single species are highly desired. Applications that provide approaches that break through existing technical barriers to substantially improve current capabilities are highly encouraged.   

The Common Fund Program - Accelerating Translation of Glycoscience: Integration and Accessibility - aims to develop accessible and affordable new tools and technologies for studying carbohydrates that will allow biomedical researchers to significantly advance our understanding of the roles of these complex molecules in health and disease. This program will enable investigators who might not otherwise conduct research in the glycosciences, to undertake the study of carbohydrate structure and function. In support of these aims, this FOA is intended to develop new approaches (catalytic methods, chemical/chemo-enzymatic methods, and technologies) to facilitate the rapid, robust, and affordable synthesis, and/or functionalization of bio-medically relevant glycans and glyco-conjugates representing 1) mammalian glycomes and 2) microbial glycans.

A central goal of the BRAIN Initiative is to understand how electrical and chemical signals code information in neural circuits and give rise to sensations, thoughts, emotions and actions. While currently available technologies can provide some understanding, they may not be sufficient to accomplish this goal. For example, non-invasive technologies are low resolution and/or provide indirect measures such as blood flow, which are imprecise; invasive technologies can provide information at the level of single neurons producing the fundamental biophysical signals, but they can only be applied to tens or hundreds of neurons, out of a total number in the human brain estimated at 85 billion. Other BRAIN FOAs seek to develop novel technology (RFA-NS-16-006) or to optimize existing technology ready for in-vivo proof-of-concept testing and collection of preliminary data (RFA-NS-16-007) for recording or manipulating neural activity on a scale that is beyond what is currently possible. This FOA seeks applications for unique and innovative technologies that are in an even earlier stage of development than that sought in other FOAs, including new and untested ideas that are in the initial stages of conceptualization.

The "epitranscriptome" refers to chemical modifications of RNA molecules.  RNA modifications in the brain have been reported to regulate the fate and function of both coding and noncoding RNAs and are emerging as a critical element of cellular function. The purpose of this initiative is to stimulate research into the functions of modified RNAs in the brain and in the associated modification proteins that act on RNA (readers, writers, and erasers) that play a role in basic neurobiological and behavioral processes implicated in mental and substance use disorders.   

This AFRI Challenge Area promotes and enhances the scientific discipline of food safety, with an overall aim of protecting consumers from microbial and chemical contaminants that may occur during all stages of the food chain, from production to consumption. This requires an understanding of the interdependencies of human, animal, and ecosystem health as it pertains to foodborne pathogens. The long-term outcome for this program is to reduce foodborne illnesses and deaths by improving the safety of the food supply, which will result in reduced impacts on public health and on our economy. In order to achieve this outcome, this program will support single-function Research Projects and multi-function Integrated Research, Education, and/or Extension Projects, and Food and Agricultural Science Enhancement (FASE) Grants that address one of the Program Area Priorities (see Food Safety RFA for details).
