Welcome to the Zagorski Lab


Research Collaborations at Case Western Reserve University

My research involves extensive collaborations, particularly with faculty in the School of Medicine. These collaborations generally fall into two categories: (1) protein misfolding human diseases (Alzheimer's, Parkinson's, Prion) and (2) NMR-related structural biology, in which the latter includes being an active member of the Cleveland Center for Structural Biology (CCSB). The CCSB is a facility operated jointly by CWRU and the Cleveland Clinic. It is located close to campus and is equipped with several high field NMR and X-ray crystallographic instruments as well as researchers who are involved primarily with protein structure determination. Below is a list of my past and present collaborators on campus:

Alzheimer's Disease

Mary Barkley Dept. of Chemistry 1996 - 1999 NMR Studies of somatostatin analogs. A graduate student from Mary's group, Paul Adams, worked part-time under my supervision. I was Co-PI on her NIH R01 grant submitted on 7/1/97.
Philip Garner Dept. of Chemistry 1995 - 1996 Synthesis, DNA Binding affinities, and structures of PNA analogs. He provided PNA samples NMR structure determination in water solution.
Donald Jacobsen Cleveland Clinic 2000 - present NMR studies of homocysteine-modified TTR. I am a collaborator with his NIH grant.
Woodrow Guo Dept. of Chemistry 2000 - 2004 NMR studies of glycopeptides and I will provide assistance with NMR work and have served as a Co-PI on several grants
Roger Marchant Dept. of Biomedical Engin. 2000 - present The structure of the ABri and Aβ amyloid proteins using AFM.

Research Collaborations at Other Institutions

Except for the collaboration at the University of Akron, all of these involve projects related to Alzheimer's disease. Below is a list of the individuals and projects:

Dale Ray University of Akron 1992 - 1998 A novel 19F to 15N NOE. He did the majority of the preliminary NMR experiments, plus assisted my students with NMR training. I submitted a grant on this topic to the Exploratory Research Program of Proctor & Gamble and the Ohio Board of Regents .
Donald Weaver Queens University 1993 - 1995 Structure of the Aβ channel. He was performing modeling and was a Co-PI on two of my NIH R01 grants.
Valerie Daggett University of Washington 1994 - 1996 I acted as a consultant for several of her grants, in which we would provide NMR data for the Aβ modeling done in her lab.
Ashley Bush Harvard University 1994 - 1998 Projects examining the effects of zinc on the structure an aggregational properties of the Aβ peptide.
Michael Vitek Duke University 1994 - 1996 He had attempted to provide us with the Aβ protein from a bacterial expression system.
Dmitry Goldgaber SUNY Stony Brook 1993 - 1994 Studying Effects of transthyretin on the structure of amyloid β-peptide. This collaboration resulted in a publication in Proc. Natl. Acad. Sci. USA.
Tsunao Saitoh UCSD 1994 - 1996 Research on the NACP protein, unfortunately he is now deceased and this collaboration has ended. I submitted a manuscript on this project to Biochemistry.
Mark Kindy University of Kentucky 1994 - 1997 Structure of serum amyloid-A (SAA) protein. We have obtained some NMR for SAA and submitted submitted an NIH grant together. Several years ago, we applied for NIH supplement to support this project.
