The Role Of Connexins And Pannexins In Mammary Gland Development And Tumorigenesis, Michael K. G. Stewart
The Role Of Connexins And Pannexins In Mammary Gland Development And Tumorigenesis, Michael K. G. Stewart
Electronic Thesis and Dissertation Repository
The identification of key regulators of breast cancer onset and progression is critical for the development of targeted therapies. Connexins and pannexins are characterized by their ability to form large-pore channels and are frequently dysregulated in cancer. However, their role in breast cancer progression remains poorly understood due to a lack of in vivo models capable of assessing the proposed and opposing roles of connexins and pannexins as both tumor suppressors and/or facilitators in multiple stages of the disease. Using 2 previously uncharacterized genetically-modified mice, connexin43 (Cx43) and connexin26 (Cx26) were evaluated for their role in normal mammary gland development …

Detection Of Ubiquitination On Syk And Documenting Syk Stability, Izabela Mazur, Wen Horng Wang, Robert J. Geahlen
Detection Of Ubiquitination On Syk And Documenting Syk Stability, Izabela Mazur, Wen Horng Wang, Robert J. Geahlen
The Summer Undergraduate Research Fellowship (SURF) Symposium
Post-translational modifications regulate the activities of proteins important to numerous diseases. Spleen Tyrosine Kinase (Syk) is particularly interesting to researchers because it modifies many targets and plays multiple roles in regulating cells in our bodies and its abnormal modifications may contribute to cancer, Alzheimer’s disease and allergies. In an attempt to study these modifications of Syk, we first looked at detecting ubiquitination on Syk protein. Ubiquitin, a small 8 kDa molecule, attaches to lysine residues on protein. The attachment of ubiquitin to Syk may cause Syk to either propagate signals onwards to activate other proteins or signal it to undergo …
A Laminin 511 Matrix Is Regulated By Taz And Functions As The Ligand For The Alpha6bbeta1 Integrin To Sustain Breast Cancer Stem Cells, Cheng Chang, Hira Lal Goel, Huijie Gao, Bryan M.

Understanding how the extracellular matrix impacts the function of cancer stem cells (CSCs) is a significant but poorly understood problem. We report that breast CSCs produce a laminin (LM) 511 matrix that promotes self-renewal and tumor initiation by engaging the alpha6Bbeta1 integrin and activating the Hippo transducer TAZ. Although TAZ is important for the function of breast CSCs, the mechanism is unknown. We observed that TAZ regulates the transcription of the alpha5 subunit of LM511 and the formation of a LM511 matrix. These data establish a positive feedback loop involving TAZ and LM511 that contributes to stemness in breast cancer.
Impact Of Differentiation Status Of Kidney Progenitors In Wilms Tumor Development, Le Huang
Impact Of Differentiation Status Of Kidney Progenitors In Wilms Tumor Development, Le Huang
Dissertations & Theses (Open Access)
Wilms tumor is one of the most common solid tumors in children. It is an embryonic cancer of the kidney and is thought to arise from undifferentiated renal mesenchyme. However, the differentiation status of cells in the mesenchyme that can give rise to Wilms tumors is unknown. Gene expression analysis of a large panel of Wilms tumor patients has identified different subsets of Wilms tumors that are distinct in their clinical outcomes and gene expression signatures. These subsets express specific genes that correspond to different stages of differentiation during renal development, suggesting that Wilms tumors may arise from transformed cells …
Deciphering The Functional Collaboration Of Mid And Bric-A-Brac 2 As Potential Regulators Of Cellular Proliferation Within Adult Drosophila Ovaries, Petra Visic
Master's Theses
Stem cell niches are highly organized and specialized microenvironments located within specific tissues of both vertebrate and invertebrate organisms [1]. In Drosophila melanogaster, three distinct stem cell niches have been identified within the ovary including the germline stem cell (GSC), follicle stem cell (FSC), and escort stem cell (ESC) niche. Recently, Fregoso-Lomas et al. [2] reported that Gurken/Epidermal Growth Factor Receptor (EGFR) signaling is modulated within posterior ovarian follicle cells by Midline (Mid). The mid gene encodes a T-box transcription factor protein that specifies cell fates in the developing heart [3][4], central nervous system [5][6], epidermis [7], and eye …
Regulation Of The Wnt/Β-Catenin Pathway By Steroid Hormones In Danio Rerio Ovarian Tissue, Macaulie Casey
Regulation Of The Wnt/Β-Catenin Pathway By Steroid Hormones In Danio Rerio Ovarian Tissue, Macaulie Casey
Summer Research
The Wnt/β-catenin signaling pathway regulates genes involved in proliferation (cell growth) and apoptosis (cell death). It has been implicated in ovarian cancer, where higher levels of β-catenin may be involved in the development of tumors. Steroid hormones play a significant role in female reproductive tissue, and studies have shown that estrogens and progestins may regulate the Wnt/β-catenin pathway. My past research suggested testosterone may also affect the pathway. Few studies have investigated how steroid hormone mimics, such as Bisphenol A (BPA), affect these regulatory patterns. This study investigated the affect of estrogen and BPA on the Wnt/β-catenin pathway in Danio …
