Suppression Of Chronically Induced Breast Carcinogenesis And Role Of Mesenchymal Stem-Like Cells, Kusum Rathore
Suppression Of Chronically Induced Breast Carcinogenesis And Role Of Mesenchymal Stem-Like Cells, Kusum Rathore
Doctoral Dissertations
Sporadic breast cancers are mainly attributable to long-term exposure to environmental factors, via a multi-year, multi-step, and multi-path process of tumorigenesis involving cumulative genetic and epigenetic alterations in the chronic carcinogenesis of breast cells from a non-cancerous stage to precancerous and cancerous stages. Epidemiologic and experimental studies have suggested that various dietary compounds like green tea and grape seed may be used as preventive agents for breast cancer control. In this research, I have developed a cellular model that mimics breast cell carcinogenesis chronically induced by cumulative exposures to low doses of environmental carcinogens. I used the chronic carcinogenesis model …
A Novel Function For Aurora B Kinase In The Regulation Of P53 By Phosphorylation, Chris P. Gully
A Novel Function For Aurora B Kinase In The Regulation Of P53 By Phosphorylation, Chris P. Gully
Dissertations & Theses (Open Access)
The mitotic kinase Aurora B plays a pivotal role in mitosis and cytokinesis and governs the spindle assembly checkpoint which ensures correct chromosome segregation and normal progression through mitosis. Aurora B is overexpressed in breast and other cancers and may be an important molecular target for chemotherapy. Tumor suppressor p53 is the guardian of the genome and an important negative regulator of the cell cycle. Previously, it was unknown whether Aurora B and p53 had mutual regulation during the cell cycle. A small molecule specific inhibitor of Aurora B, AZD1152, gave us an indication that Aurora B negatively impacted p53 …
