Antifolate Modulators Of Amp-Activated Protein Kinase Signaling As Cancer Therapeutics, Scott Rothbart
Antifolate Modulators Of Amp-Activated Protein Kinase Signaling As Cancer Therapeutics, Scott Rothbart
Theses and Dissertations
Since its discovery, it was appreciated that the antifolate pemetrexed had multiple targets within folate metabolism. This laboratory was instrumental in showing that pemetrexed elicited its primary action as a thymidylate synthase inhibitor. Unusual for an antifolate, pemetrexed showed significant clinical activity against malignant pleural mesothelioma and non-small cell lung cancer. Accordingly, the FDA recently issued first-line approvals for pemetrexed in these diseases, leading us to question whether the effects of pemetrexed on other folate-dependent targets could explain this atypical clinical activity of the drug. Studies in this dissertation showed that in addition to thymidylate synthase inhibition, pemetrexed was also …
Cell Death And Sustained Senescence Arrest In Colon Carcinoma And Melanoma Tumor Cells In Response To The Novel Microtubule Poison, Jg-03-14, Jonathan Biggers
Cell Death And Sustained Senescence Arrest In Colon Carcinoma And Melanoma Tumor Cells In Response To The Novel Microtubule Poison, Jg-03-14, Jonathan Biggers
Theses and Dissertations
Previous studies from this and other laboratories have shown that the novel microtubule poison, JG-03-14, which binds to the colchicine binding site of tubulin, has the capacity to promote both autophagy and apoptosis in breast tumor cells, as well as interfering with endothelial cell function and potentially disrupting tumor vasculature. The current work was designed to investigate the interaction between JG-03-14 and cell culture models of colon carcinoma and melanoma, specifically HCT116 human colon carcinoma cells and B16F10 murine melanoma cells. In both cases, JG-03-14 promoted death in the bulk of the treated population. FACS analysis, DAPI and TUNEL staining …
Nursing Home Organizational Characteristics And Utilization Of Cancer-Related Medical Services, Chun-Chieh Lin
Nursing Home Organizational Characteristics And Utilization Of Cancer-Related Medical Services, Chun-Chieh Lin
Theses and Dissertations
Cancer is the second leading cause of death in the U.S and is more common among the elderly. Since frailty and other age related conditions put the elderly at risk for nursing home care, nursing homes may be the site of care and death for many elderly cancer patients. However, there is a large gap in knowledge concerning cancer treatment of elderly nursing home residents. Since residents rely heavily on their nursing facilities, nursing homes might influence them in their treatment decisions. After controlling for resident and nursing home market characteristics, this study applies Andersen’s Behavioral Model to examine whether …
