Combined Antiproliferative Effects Of The Aminoalkylindole Win55,212-2 And Radiation In Breast Cancer Cells, Sean Emery
Combined Antiproliferative Effects Of The Aminoalkylindole Win55,212-2 And Radiation In Breast Cancer Cells, Sean Emery
Theses and Dissertations
The potential antitumor activity of mixed CB1/CB2 cannabinoid receptor agonists, such as the aminoalkylindole WIN55,212-2 (WIN2), has been extensively studied, but little information is available as to their potential interaction with conventional cancer therapies, such as ionizing radiation (IR). In the present work, we investigated the effects of WIN2 on the antiproliferative effects of radiation in human (MCF-7 and MDA-MB-231) and murine (4T1) breast cancer cells, as well as an immortalized human breast epithelial cell line (MCF-10A). WIN2 or radiation alone inhibited breast tumor growth, while the combination of WIN2 and radiation was more effective than either agent alone in …

Background: As detection and treatment of cancer has advanced, the number of working age women with breast cancer has increased. This study provides new information on the intersection of breast cancer treatment and job tasks and how, together, they impact employed and newly diagnosed women.
Methods: The sample comprised 493 employed women within two months of initiating treatment. Job satisfaction and demands were assessed by pre-diagnosis recall along with measures of mental and physical health and assessed again nine months after initiating treatment. Using seemingly unrelated regression, we tested the effect of job tasks and satisfaction on mental and …
Treatment-Induced Breast Cancer Dormancy And Relapse, Rebecca Keim
Treatment-Induced Breast Cancer Dormancy And Relapse, Rebecca Keim
Theses and Dissertations
When breast tumor cells encounter stress due to cancer therapies, they may enter a dormant state, escaping from treatment-induced apoptosis. Dormant cells may eventually regain proliferative capabilities and cause recurrent metastatic disease, which is the leading cause of mortality in breast cancer patients. We sought to determine if a high dose of radiation therapy (RT) or combined chemo-immunotherapy, with and without the blockade of autophagy by chloroquine (CQ), could overcome treatment-induced tumor dormancy or relapse. We found that autophagy contributes in part to treatment-induced tumor dormancy. We also found that three therapeutic strategies were successful in inhibiting or preventing tumor …
Sildenafil And Celecoxib Interact To Kill Breast Cancer Cells, Brittany Binion
Sildenafil And Celecoxib Interact To Kill Breast Cancer Cells, Brittany Binion
Theses and Dissertations
Breast cancer is the second most commonly diagnosed cancer among American women and is responsible for the second highest number of cancer-related deaths. Targeted therapeutic agents sildenafil, a phosphodiesterase type 5 inhibitor, and celecoxib, a cyclooxygenase-2 inhibitor, have been used individually in conjunction with other chemotherapeutic agents to enhance cell killing in a variety of cancers. Sildenafil when combined with traditional chemotherapeutic drugs, such as the taxanes and anthracyclines, or celecoxib combined with traditional hormone therapies have been used to increase cytotoxicity and cell killing. The data presented here demonstrates that the novel combination of sildenafil and celecoxib work together …
