LIPID METABOLITES AND PATHWAYS STRATEGY CONSORTIUM

点击翻译按钮获取中文摘要

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. This project is supported by an NIGMS Glue Grant. The overall program has the following objectives: (1) Separate and detect all of the lipids in a specific cell and discover and characterize any novel lipids that may be present. (2) Quantitate each of the lipid metabolites present and quantitate the changes in their levels and location during cellular function. (3) Define the biochemical pathways for each lipid and develop lipid maps which define the interaction networks. To aid the Neutral Lipids Core, Lipidomics Focus Area, directed by R.C. Murphy, Univ. Colorado Health Sciences Center, the BUSM MS Resource assists in the structural determinations of novel neutral lipids. C. E. Costello provides expertise on new methods for mass spectral analysis of lipids to the Lipid MAPS program and attends the annual meeting of LipidMaps investigators. She presented an invited lecture at the May 2010 meeting of Lipid Maps investigators. A posted coauthored with postdoctoral fellow Hyejung Park has been accepted for presentation at the May 2011 meeting.
