Echogenic Liposomes For Nitric Oxide Delivery And Breast Cancer Treatment, Soo Yeon Lee Female
Echogenic Liposomes For Nitric Oxide Delivery And Breast Cancer Treatment, Soo Yeon Lee Female
Dissertations & Theses (Open Access)
Liposomes, also known as nontoxic, biodegradable, and non-immunogenic therapeutic delivery vehicles, have been proposed as a carrier for drugs and antitumor agents in cancer chemotherapy. Echogenic liposomes (ELIP) have the potential to entrap air or bioactive gas to enhance acoustic reflectivity in ultrasound and are used as a contrast agent. The innovative part of this study is based on a novel concept to encapsulate nitric oxide (NO) gas into ELIP, deliver it to breast cancer cells, and control its release via direct ultrasound exposure. Studies on the effect of NO in tumor biology have shown that a high levels of …
The Regulation Of Liv-1 Mrna In Mda-Mb-231 Human Breast Cancer Cells And Its Association With E-Cadherin (Cdh1), Leelyn Chong
The Regulation Of Liv-1 Mrna In Mda-Mb-231 Human Breast Cancer Cells And Its Association With E-Cadherin (Cdh1), Leelyn Chong
Master's Theses
LIV-1, the estrogen-regulated gene encoding a member of the ZIP family of zinc transporters (SLC39A6), has been implicated in both growth and metastasis of estrogen-receptor (ER) positive (+) and negative (-) breast cancer cells. In ER+ breast cancer cells, LIV-1 expression is induced by both estrogen and insulin. In embryonic cells, LIV-1 has also been negatively associated with the expression of the cell adhesion protein, E-cadherin (CDH1), thought to play a role in metastasis. In the present study, we investigated the regulation of LIV-1 and its relationship to CDH1 in MDA-MB-231 ER- breast cancer cells. Cells were …
Defining The Role Of Egfr Acetylation In Cellular Processes: Clinical Implications, Hui Song
Defining The Role Of Egfr Acetylation In Cellular Processes: Clinical Implications, Hui Song
Dissertations & Theses (Open Access)
Epidermal growth factor receptor (EGFR) is a cell membrane tyrosine kinase receptor and plays a pivotal role in regulating cell growth, differentiation, cell cycle, and tumorigenesis. Deregulation of EGFR causes many diseases including cancers. Intensive investigation of EGFR alteration in human cancers has led to profound progress in developing drugs to target EGFR-mediated cancers. While exploring possible synergistic enhancement of therapeutic efficacy by combining EGFR tyrosine kinase inhibitors (TKI) with other anti-cancer agents, we observed that suberoylanilide hydroxamic acid (SAHA, a deacetylase inhibitor) enhanced TKI-induced cancer cell death, which further led us to question whether SAHA-mediated sensitization to TKI was …

A Breast Cancer Stem Cell Model Created From Mmtv-Pymt Mice Applicable To Human Breast Cancer, Denise Grant Lanza
Legacy Theses & Dissertations (2009 - 2024)
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 …
In Vitro Inhibitory Activity Of Black Seed Oil And Potassium Chloride Against The Biomarkers Of Triple Negative Breast Cancer, Tamaratina Jombai
In Vitro Inhibitory Activity Of Black Seed Oil And Potassium Chloride Against The Biomarkers Of Triple Negative Breast Cancer, Tamaratina Jombai
LSU Master's Theses
Breast cancer is the leading cause of death among women and is highly heterogeneous in nature. One very aggressive subtype of this disease is Triple Negative Breast Cancer. Triple Negative Breast Cancer (TNBC), is a very aggressive disease characterized by the lack of expression of estrogen receptors (ER), progesterone receptors (PR) and human epidermal growth factor receptor-2 (HER-2). TNBC patients account for approximately 15% of total breast cancer patients. This breast cancer subtype is characterized by high mortality rate, and is typically associated with poor prognosis. Current clinical methods have proven to have low success rates against TNBC, it is …

Inhibitory Activity Of Ginger Oil Against Breast Cancer Cells, Namrata Karki
LSU Master's Theses
Breast cancer is the leading cause of cancer related mortality in women. The estimated new cases and death for 2010 in the US for females were 207,090 and 39,840 and for men were 1,970 and 390 respectively. Breast cancer cells contain cancer stem cells (CSCs), which represent less than 5% of the total cancer cell population, but accounts for continuous proliferation and growth. Breast cancer is highly metastatic and can spread to various parts of the body. Signaling through cell surface markers, including CD44/CD24/ALDH1 in breast cancer, pro-survival factors, including Hsp90 and other client proteins, angiogenic biomarkers and telomerase activity …
