Bartonella Bacilliformis: Understanding The Underlying Causes Of Verruga Peruana Formation During Carrion?S Disease, Drew Eric Kohlhorst
Bartonella Bacilliformis: Understanding The Underlying Causes Of Verruga Peruana Formation During Carrion?S Disease, Drew Eric Kohlhorst
Biology Dissertations
Bartonella, a group of Gram negative facultative intracellular bacteria, are known to cause diseases, such as Cat Scratch Disease, Trench Fever and Carrion’s Disease, that involve angiogenesis during the infective cycle. B. bacilliformis, the etiological agent of Carrion’s Disease, causes a bi-phasic infection resulting in the formation of blood-filled angiogenic proliferative cutaneous nodules called verruga peruana. The work presented here was undertaken to characterize the mechanism by which these nodules are produced. Previous work in our laboratory suggested that the Bartonella henselae genome contains a homologue to the virB operon, a set of genes coding for a Type IV Secretion …

The C-Phycocyanin/Beta Protein Inhibits Cancer Cell Proliferation, Haizhen Wang
Biology Theses
C-Phycocyanin (C-PC) from blue-green algae has been reported to have various pharmacological characteristics, including anti-inflammatory and anti-cancer activities. In this study, the beta-subunit of C-PC (ref to as C-PC/beta) was expressed and purified from bacteria E. coli BL-21. The recombinant C-PC/beta has been demonstrated to have anticancer properties. Under the treatment of 5 microM of the recombinant C-PC/beta, four different cancer cell lines accrued a high proliferation inhibition and apoptotic induction. The C-PC/beta interacts with membrane-associated beta-tubulin and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) has been found. Under the treatment of the C-PC/beta, depolymerization of microtubulin and actin-filament was observed. The cells underwent …
