Characterization of transcriptional changes after partial hepatectomy (PH) may provide an understanding of the underlying biological processes involved in compensatory growth and regeneration of liver mass after drug induced liver injury (DILI). Development of this type of model would prove useful as a model for assessment of potential drug induced liver injury that induces a compensatory proliferative response. In this project, we developed a surgical regeneration model (70% partial hepatectomy) in liver of male Sprague Dawley rats. Individual gene markers associated with a regenerative response in liver were evaluated in the partial hepatectomy model and compared to five previous studies …
Characterizing The Dynamics And Functional Role Of Site-Specific Phosphorylation Of G Protein-Coupled Receptors, John M. Busillo
Characterizing The Dynamics And Functional Role Of Site-Specific Phosphorylation Of G Protein-Coupled Receptors, John M. Busillo
Full-Text Theses & Dissertations
Phosphorylation of G protein-coupled receptors (GPCRs) by GPCR kinases (GRKs) and the subsequent recruitment of arrestin is a well-established paradigm that initiates the process known as desensitization. However, an emerging theme in GPCR regulation is the possibility of differential regulation dictated by the phosphorylation pattern elicited by the different members of the GRK family. Therefore, we have used small interfering RNA-mediated knock down of the GRKs and arrestins in an attempt to better understand how phosphorylation regulates the activity and signaling of the M3 muscarinic acetylcholine receptor (M3 mAChR) and CXCR4, two receptors endogenously expressed in HEK293 cells.

Role Of Immunodominant T Cell Responses To Minor Histocompatibility Antigens In A Mouse Model Of Graft-Versus-Host Disease, Marc Adam Berger, B.S. Thomas Jefferson University
Role Of Immunodominant T Cell Responses To Minor Histocompatibility Antigens In A Mouse Model Of Graft-Versus-Host Disease, Marc Adam Berger, B.S. Thomas Jefferson University
Full-Text Theses & Dissertations
Graft-versus-host-disease (GVHD) is a major complication of major histocompatibility complex (MHC) matched bone marrow transplantation. GVHD is the result of an immune-mediated attack, by T lymphocytes derived from donor bone marrow, against recipient tissues expressing minor histocompatibility antigen (miHA) differences. There is a lack of knowledge concerning the nature of in vivo immune responses to miHA during GVHD. C57BL/6By (B6/By) and BALB.B mouse strains both express the H-2B MHC haplotype but differ at more than 40 miHA loci. Both the in vitro and in vivo T cell responses to miHA expressed by BALB.B and CXB recombinant inbred (RI) strains of …
