Dynamic Mechanisms Of Multidrug Resistance In Human Cancers And Gram Negative Pathogens, Lauren Ammerman
Dynamic Mechanisms Of Multidrug Resistance In Human Cancers And Gram Negative Pathogens, Lauren Ammerman
Biological Sciences Theses and Dissertations
This dissertation focuses upon dynamic agents of multidrug resistance (MDR). We used a combination of in silico and in vitro techniques to investigate two membrane transporters that confer MDR – P-glycoprotein, which confers MDR in human cancers, and MtrD, which confers MDR in Neisseria gonorrhoeae. Inhibitors targeting both proteins have tremendous potential for use as co-therapeutics in the treatment of multidrug resistant cancers, or of multidrug resistant infections. However, previously identified inhibitors of P-gp have failed clinical trials due to off-target effects and associated toxicities. Furthermore, the molecular mechanism of antibiotic transport by MtrD is poorly understood, and this dearth …

In Vitro Expression And Purification Of Class I Mhc Molecules, Loi Cheng
In Vitro Expression And Purification Of Class I Mhc Molecules, Loi Cheng
Honors Scholar Theses
The major histocompatibility complex (MHC) is a gene family responsible for many critical functions of the immune system in most vertebrates. The MHC consists of three classes differentiated by their structure and function, and MHC class I encodes antigen binding proteins as well as chaperone and accessory proteins such as tapasin. The purpose of this project is to reconstitute several human MHC class I molecules in their peptide-filled and peptide-deficient forms, and to purify these proteins for biochemical study. The expressed proteins include wild type and mutant variants of the fusion protein human leukocyte antigen HLA-B*0801-fos, and human beta-2-microglobulin (β2m). …
