We are testing a new system for linking grants to scientists.
The funding information displayed below comes from the
NIH Research Portfolio Online Reporting Tools and the
NSF Award Database.
The grant data on this page is limited to grants awarded in the United States and is thus partial. It can nonetheless be used to understand how funding patterns influence mentorship networks and vice-versa, which has deep implications on how research is done.

R15Activity Code Description: Supports small-scale research projects at educational institutions that provide baccalaureate or advanced degrees for a significant number of the Nation’s research scientists but that have not been major recipients of NIH support. The goals of the program are to (1) support meritorious research, (2) expose students to research, and (3) strengthen the research environment of the institution. Awards provide limited Direct Costs, plus applicable F&A costs, for periods not to exceed 36 months. This activity code uses multi-year funding authority; however, OER approval is NOT needed prior to an IC using this activity code. |
Aptamers to Distinguish Functional Modification of Target Proteins by Affinity Pr
[unreadable] DESCRIPTION (provided by applicant): The emergence of functional genomics has led to a growing need for analyzing molecular variants and post-translational modifications of proteins that often determine the biological results of changes at the genomic level. The proposed work is aimed at utilizing aptamers, oligonucleotide ligands for specific target molecules, to distinguish between these molecular variants. To accomplish this, affinity probe capillary electrophoresis (APCE) will be applied as a rapid method to detect fluorescently labeled aptamers that are bound to their targets. In particular, the ability of aptamers for vascular endothelial growth factor (VEGF), a protein implicated in tumor growth, to bind selected peptide domains of the VEGF protein will be investigated. After establishing reliable APCE methods for a selected peptide domain, specific modified peptides that incorporate phosphoserine and/or phosphothreonine will be investigated as models of typical post-translational modifications. Capillary electrophoresis aptamer selection will further identify oligonucleotide sequences that preferentially bind specific peptides. These studies will lead to the development of aptamer arrays for individual molecules, each targeting a particular domain or functional modification of the protein. Such panels would be novel molecular tools for rapid and simple monitoring of disease-linked functional changes in protein molecules with potential applications in drug screening and disease diagnosis. This work will lead to the development of aptamers that target specific domains or functional modifications of target proteins. Such aptamers could be used for signaling the presence of proteins associated with particular disease states, or potentially as pharmaceutical agents that can block or modify the action of these proteins.
