Prophylactic Cranial Irradiation Reduces The Incidence Of Brain Metastasis In A Mouse Model Of Metastatic Breast Cancer, Daniel L. Smith
Prophylactic Cranial Irradiation Reduces The Incidence Of Brain Metastasis In A Mouse Model Of Metastatic Breast Cancer, Daniel L. Smith
Dissertations & Theses (Open Access)
Prophylactic cranial irradiation (PCI) is a preventative whole-brain irradiation technique used to reduce the incidence of brain metastasis and improve overall survival in select patients with small cell lung cancer and acute lymphoblastic leukemia. A population of breast cancer patients – stage IV, HER2+ or triple-negative – has emerged as having a high risk of developing brain metastases. Because only 10-20% of breast cancer patients diagnosed with brain metastases survive longer than one year, in this high-risk population the benefit of PCI – potential for reduced incidence of brain metastasis and improved overall survival – may outweigh the risks – …

AMPK activation and Ubiquitin Proteasome System (UPS) inhibition have gained great attention as therapeutic strategies for the treatment of certain types of cancers. While AMPK serves as a master regulator of cellular metabolism, UPS regulates protein homeostasis. Although the crosstalk between them is suggested, the relationship between these two important pathways is not very clear. We observed that proteasome inhibition leads to AMPK activation in human breast cancer cells. We report that a variety of proteasome inhibitors activate AMPK in all of the tested cancer cell lines. Our data using Liver Kinase B1 (LKB1)-deficient cancer cells suggests that proteasome inhibitor-induced …
Vitamin D Regulates Metabolic Gene Expression, Glutamate And Glutamine Utilization, And Mitochondrial Function In Human Mammary Epithelial Cells, Sarah Beaudin
Legacy Theses & Dissertations (2009 - 2024)
Exposure to 1,25-Dihydroxyvitamin D (1,25D) decreases proliferation and induces differentiation in telomerase-immortalized human mammary epithelial (hTERT-HME1) cells. The studies described here addressed the mechanisms by which these effects are exerted. Microarray experiments were used to identify a subset of metabolic genes and pathways that are altered by 1,25D. In particular, genes involved in glutamate and glutamine utilization, including SLC1A1 and GLUL, were studied. Interestingly, qPCR analysis in a panel of six cell lines, representing either normal epithelial tissue or breast cancer, demonstrated diverse gene expression responses to 1,25D. In an isogenic model of mammary cell transformation, 1,25D altered gene expression …
