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.

Chemical modifications of proteins, DNA and RNA nucleoside moieties play critical roles in regulating gene expression.  Emerging evidence suggests these RNA modifications (epitranscriptomics) have substantive roles in basic biological processes. Recent studies in yeast, Drosophila and rodent models demonstrate stressors can induce RNA modifications, with specific epitranscriptomic reprogramming of some regulatory RNAs.  The purpose of the Functional RNA Modifications Environment and Disease (FRAMED) FOA is to solicit and support R21 applications that propose innovative, high risk, high reward research addressing how environmental exposures impact this layer of cellular regulation.

This Funding Opportunity Announcement (FOA) solicits Small Business Innovative Research (SBIR) grant applications from small business concerns (SBCs) to develop novel technologies to expand the capability for molecular analyses of banked frozen or formalin-fixed, paraffin-embedded tissues. There is a need for improved tissue preservation methods that maintain histologic features while preserving high quality DNA, RNA, protein and small molecules in archived tissue from rodent and human studies. In addition, novel approaches are needed to preserve DNA, RNA, and small molecules during collection and storage of biological samples.

This Funding Opportunity Announcement (FOA) solicits R01 grant applications to develop novel technologies that will enable no less than one order of magnitude improvement in DNA sequencing, and practical methods for direct RNA sequencing. Advances in genomics and more broadly in biomedical research have been greatly facilitated by significant and sustained DNA sequencing throughput increases and cost decreases. The goal now is to improve the quality and efficiency of DNA sequencing and enable direct RNA sequencing (e.g., longer read lengths, faster turn-around time, greater accuracy, and higher-throughput etc.) at reasonable costs with the anticipation that significant advances in any of these and related areas would make significant contributions to the mission of NHGRI and the field of genomics, including to many of NHGRI's other technology development goals.

The purpose of this FOA is to support generation of single cell RNA-sequencing datasets for at least one brain region relevant to persistent HIV infection and opioid use disorder. Applications that are not responsive to this FOA will be returned without review. To be responsive to this FOA, proposed projects should be framed to answer one or more vexing questions about persistent HIV infection in the CNS. The major thrust of the proposed project also MUST: exploit single nucleus or single cell transcriptomic assays with the goal of identifying the types of cells within at least one NIDA-relevant brain region (e.g. PFC, NAc, VTA, striatum, insula, or other appropriately justified region) and how the cell types and individual cells within that region differ from one another in terms of gene expression. focus on human post-mortem brain tissue from controls, individuals with chronic opioid exposure, HIV-infected individuals, and HIV-infected individuals with chronic opioid exposure. propose to detect HIV proteins or RNA or DNA within the single cells or nuclei to be assayed.

The National Institute on Drug Abuse (NIDA) will solicit proposals from qualified organizations capable of maintaining and expanding the NIDA Center for Genetic Studies. In this effort, the contractor will be required to: (1) Receive de-identified clinical, diagnostic, pedigree structure, environmental exposure information and other phenotypic data along with blood samples or other biospecimens from funded grants and/or contracts supporting research on the genetics of addiction and addiction vulnerability; (2) Process these data and materials to create databases, serum, DNA, RNA, and cell lines; (3) Widely distribute all data and materials in the NIDA Human Genetics Initiative to qualified investigators in the scientific community in a cost effective manner; (4) Maintain storage of data and biomaterials; (5) As stipulated by NIDA staff, perform microarray typing on pre-existing and/or new de-identified biospecimens; (6) As stipulated by NIDA staff, perform high-throughput sequencing on pre-existing and/or new de-identified biospecimens for genomic and/or epigenomic analyses; (7) Support the creation of reprogrammed cellular derivatives, such as induced pluripotent stem cells (iPSCs) to facilitate the molecular and cellular study of brain development and addiction processes; (8) Create a cyberinfrastructure that enables interoperability and full access to distributed data, software and other information science resources as well as research summaries and outbound links for all addiction related studies available through the NIH database of Genotype and Phenotype (dbGaP) system; and (9) Faciliate NIDA genetic studies data (both genotype and phenotype) being uploaded into NIH databases such as BioSample, and the dbGaP systems.

This Funding Opportunity Announcement (FOA) solicits applications to start a new initiative, the Genomics of Gene Regulation (GGR), which is intended to explore genomic approaches to understanding the role of genomic sequence in the regulation of gene networks. A long-term goal of functional genomics is to decipher the rules by which gene networks are regulated and to understand how such regulation affects cellular function, development and disease. The GGR initiative will address the genome-proximal component of the regulation of gene networks by supporting a set of demonstration projects to develop and validate models that describe how a comprehensive set of sequence-based functional elements work in concert to regulate the finite set of genes that determine a biological phenomenon, using RNA amounts, and perhaps transcript structure, as the readout. This FOA seeks to support substantial improvement in the methods for developing gene regulatory network models, rather than an incremental improvement on existing methods. This work will move the field closer to the long-term goal of reading DNA sequence and accurately predicting when and at what levels a gene is expressed, in the context of a particular cell state. These demonstration projects will be organized as a research consortium to accelerate progress through the coordination of analytical methods and functional genomic data.

This Funding Opportunity Announcement (FOA) seeks grant applications to develop major advances in genomic technologies. Advances in genomics and more broadly in biomedical research have been greatly facilitated by significant and sustained genomics technology throughput increases, cost decreases, and improvements in ease of use. The proposed technology development work should allow comprehensive genomic analysis of features not assayable today, or an increase of no less than an order of magnitude improvement in an existing technology in terms of data quality, throughput, efficiency or comprehensiveness (individually or in combination). This FOA explicitly excludes the development of novel technologies for DNA sequencing and for direct RNA sequencing; those projects should respond to a parallel set of FOAs (RFA-HG-18-001, RFA-HG-18-002, and RFA-HG-18-003).
