Long noncoding RNAs (lncRNAs) are emerging as key molecules regulating several cellular pathways and contributing to the development and progression of different diseases including cancer. The epithelial-to- mesenchymal transition (EMT), a molecular reprogramming process that plays a critical role in cancer metastasis, involves a complex interaction between protein coding and non-coding transcripts including lncRNAs. Understanding the biological significance of those lncRNAs of relatively unknown function, may help to uncover potential therapeutic targets for the aggressive subtypes of breast and other cancers. In this study, we examined the expression profiles of more than 17,000 lncRNAs in a large set of patients’ …

The Role Of N-Myc Downstream Regulated Gene 1 In Breast Cancer Lipid Metabolism, Christopher James Sevinsky
The Role Of N-Myc Downstream Regulated Gene 1 In Breast Cancer Lipid Metabolism, Christopher James Sevinsky
Legacy Theses & Dissertations (2009 - 2024)
Altered carbohydrate and lipid metabolism are increasingly well characterized hallmarks of aggressive breast cancers. While aerobic glycolysis, or “the Warburg effect”, is a well-established metabolic adaptation exploited by tumor cells, the understanding of unique aspects of cancer lipid metabolism lags behind. This is especially true regarding the coordination of complex lipid synthesis and trafficking pathways, which remains poorly understood. N-Myc Downstream Regulated Gene1 (NDRG1) is overexpressed in many solid tumors, but its function is unclear. The importance of NDRG1 is best exemplified by the effect of null mutations on human physiology: inactivating mutations give rise to the severe autosomal recessive …

Inflammatory breast cancer (IBC) is a rare and particularly lethal form of breast cancer. Despite aggressive therapeutic approaches, the 5-year survival rate is only 34%. As this disease is severely understudied, we have investigated the therapeutic potential of the novel hydroxamic acid-derived histone deacetylase inhibitor (HDACi), CG-1521 in comparison to a structurally similar compound, Trichostatin A (TSA) in two IBC cell lines: SUM149PT and SUM190PT. In these cells, CG-1521 and TSA induce dose- and time-dependent induction of cell cycle arrest and apoptosis regardless of the presence of 17β-estradiol (E2). Interestingly, the cell lines have considerably different sensitivities to these treatments …

Cancer stem cells are the seeds of tumor growth, but there are limited cell-based methods that exist to study the properties of these cells. To create a model of breast cancer stem cells, we isolated tumors from MMTV-PyMT mice. Two out of the four different cell types isolated survived in culture, CD44+CD24- and CD24+CD49f+CD44low. We found that we could initiate tumors with as few as 10 cells injected subcutaneously in the hind leg or orthotopically in the cleared fat pad with CD24+ cells. However, we could not initiate tumors with injection of CD24- cells. We found a requirement for TICs …
