Effects Of Phytochemicals From Rhodiola Crenulata On Highly Invasive Breast Cancer Cell Lines And Embryonic Models Of Migration, Adaris Rodriguez-Cortes Sep 2013

Effects Of Phytochemicals From Rhodiola Crenulata On Highly Invasive Breast Cancer Cell Lines And Embryonic Models Of Migration, Adaris Rodriguez-Cortes

Open Access Dissertations

The root of the Tibetan plant Rhodiola crenulata is part of eastern traditional medicine. Studies have suggested that members of the Rhodiola genus display anticancer properties. In this study we examine the effect of R. crenulata in a cellular model of invasive breast cancer, this disease being the second cause of cancer death among women in the US. Deregulation of the Wnt/β-catenin pathway has been frequently observed in breast cancers and appears to have a key role in the transformation of benign cells to a malignant form. Although mutations of the Wnt growth factor are rarely observed in cancer, the …


Identification Of Epithelial Stromal Interaction 1 And Epidermal Growth Factor Receptor As Novel Kruppel-Like Factor 8 Targets In Promoting Breast Cancer Progression, Tianshu Li Jan 2013

Identification Of Epithelial Stromal Interaction 1 And Epidermal Growth Factor Receptor As Novel Kruppel-Like Factor 8 Targets In Promoting Breast Cancer Progression, Tianshu Li

Electronic Theses and Dissertations

Breast cancer is the major cause of cancer death among women worldwide. Understanding the mechanisms underlying breast cancer progression remains urgent for developing effective treatment strategies to eliminate breast cancer mortality. Our recent studies have demonstrated that Krüppel-like transcriptional factor 8 (KLF8) plays a critical role for breast cancer progression. Other studies have shown that Epithelial stromal interaction 1 (EPSTI1), a recently identified stromal fibroblast-induced gene in non-invasive breast cancer cells and epidermal growth factor receptor (EGFR) are highly overexpressed in aggressively invasive breast carcinomas including triple negative breast cancers. In this thesis project, we demonstrate high co-overexpression of KLF8 …

Rab5 Function In Breast Cancer Cells, Nicole Porther, M Alejandro Barbieri Dec 2012

Rab5 Function In Breast Cancer Cells, Nicole Porther, M Alejandro Barbieri

Nicole Porther

Metastasis is characterized pathologically by cell invasion, proliferation, migration and angiogenesis. Growth factors, which include epithelial growth factor (EGF), insulin growth factors I and II (IGFI and IGFII); have been associated with most if not all of the features of metastasis.  Our study has highlighted the possible role growth factors may have in mediating cancer metastasis via Rab GTPses.  We determined that the invasive and migratory properties of breast cancer cells were abrogated in cell lines that only expressed the inactive (GDP-bound) form of Rab 5 irrespective of growth factor stimulation. Breast cancer cell lines expressing the wild type and …
