Synthesis And Investigation Into The Estrogen Receptor Antagonist Activity Of Isoflavans And Their Synthetic Derivatives, Nikiwe N. Tsipa, Catherine H. Kaschula, Willem Van Otterlo, Amanda Swart

Research Symposium

Background: Breast cancer (BC) is the most invasive and prevalent cancer in women in South Africa, with numbers as high as 1 in 8 women in urban areas and with a large percentage being ER-positive (ER+). ER+ BC cells are reliant on the binding of the natural ligand 17β-estradiol (E2) to ERα and ERβ isoforms which drives tumor growth1. ER antagonists and inhibitors of estrogen synthesis are therefore widely used therapeutic agents in the treatment of BC. Isoflavans are natural products found in many dietary plants. They are phytoestrogens, able to act as natural anti-breast cancer agents, acting as ER …

Research Symposium

Background: Hepatocellular carcinoma (HCC) is a primary malignant liver tumor that commonly occurs as a progression of chronic liver inflammation. Sorafenib is the standard first-line systemic drug for advanced HCC, but the acquired resistance to sorafenib results in limited benefits. The mechanism underlying sorafenib resistance in HCC remains unclear. Recently, we have identified a multifunctional oncoprotein Y-box binding protein-1 (YB-1) that dysregulates a wide range of genes involved in drug resistance in other cancers and is responsible for increasing the IC-50 of sorafenib in HCC cell lines. In this study we will analyze the signaling pathways and genes regulated by …

The Role Of Zinc In Psd-95 Palmitoyl Modification, Luis F. Acosta, Lili Guerra, Safiya Syed, Ivonn Ruvalcaba, Yonghong Zhang, Xiaoqian Fang

Research Symposium

Postsynaptic density-95 (PSD-95) is a membrane-associated guanylate kinase that mediates localization of receptors in the excitatory postsynaptic density. It has been reported that PSD-95 mediates postsynaptic localization of NMDA receptors and anchors postsynaptic AMPAR receptors mainly through its postsynaptic membrane targeting by its N-terminal palmitoylation. Recent studies have shown that Ca2+/calmodulin blocks palmitoylation of PSD-95 by binding at the N-terminus of PSD-95, which promotes dissociation of PSD-95 from the postsynaptic membrane and causes loss of surface AMPARs in cultured neurons. Another metal ion zinc is found in various areas of the brain. As an endogenous neuromodulator, zinc plays a role …

The Development Of Fviii Inhibitor In Hispanic American Patients With Hemophilia A Critically Impacts Coagulation Potential, Shuchita Jhaveri, Hoang Nguyen, Marcio A.A. Almeida, Vincent P. Diego, Satish Kumar, Juan M. Peralta, Joanne E. Curran, Bernadette W. Luu, Donna M. Lehman, Ralph A. Defronzo, Laura Almasy, Sarah Williams-Blangero, Ravi Duggirala, John Blangero, Tom E. Howard

Research Symposium

Background: Hemophilia A (HA) is caused by deficiencies in plasma-FVIII and heterogeneous factor-VIII-gene mutations that impair intrinsic coagulation amplification. In severe hemophilia A patients (HAPs), FVIII infusions are begun at toddlerhood to prevent hemarthrosis induced crippling. However, approximately 30% of these patients develop FVIII inhibitors. Gain-of-function mutations in the common pathway of coagulation increases coagulation potential and decreases bleeding and FVIII-utilization in HAPs which should decrease FVIII-inhibitor-risk. We identified loss-of-function mutations in this pathway which decrease coagulation-potential as they increase FVIII-inhibitor risk in HAPs.

Methods: We screened Mexican-American-pedigrees of the South-Texas-Family-Study (STFS) for protein-altering-variants. Subjects were genotyped using Illumina-exome-24-chip. Protein-altering-variants …

Tc-Ptp Overexpression Attenuates Skin Cancer Formation During Environmental Skin Carcinogenesis, Zahidur Rahmann, Carson Bogatto, Serena Olivarez, Dae Joon Kim

Research Symposium

Background: T-cell protein tyrosine phosphatase (TC-PTP), encoded by Ptpn2, has been shown to function as a tumor suppressor during skin carcinogenesis.

Methods: we generated a novel epidermal specific TC-PTP-overexpressing (K5HA.Ptpn2) mouse model to show that TC-PTP contributes to the attenuation of chemically induced skin carcinogenesis through the synergistic regulation of STAT1, STAT3, STAT5, and PI3K/AKT signaling.

Results: We found overexpression of TC-PTP increased epidermal sensitivity to DMBA-induced apoptosis and it decreased TPA-mediated hyperproliferation, coinciding with reduced epidermal thickness. Inhibition of STAT1, STAT3, STAT5 or AKT reversed the effects of TC-PTP overexpression on epidermal survival and proliferation. Mice overexpressing TC-PTP in …

Stress-Induced Changes In Carf Expression Determine Growth Arrest, Apoptosis, Or Malignant Transformation In Cultured Human Cells: Molecular Evidence And Its Application, Mallika Khurana, Rajkumar Singh Kalra, Anupama Chaudhary, Amr Omar, Xiaoshuai Li, Sunil C. Kaul, Renu Wadhwa

Research Symposium

Background: CARF (Collaborator of ARF)/CDKN2AIP is an essential protein, first cloned as a binding partner of ARF. It was subsequently shown to interact with p53, HDM2 proteins and regulate growth arrest and apoptosis by its multimodal mechanism of action. Over-expression of CARF caused senescence like growth arrest of cells, its knock-down triggered apoptosis. Intriguingly, malignantly transformed cells showed high level of CARF expression. Based on these findings, we hypothesized that level of CARF expression may be a key determinant of cell proliferation fates; where an increase in its levels causes growth arrest/senescence, but beyond a threshold it activates carcinogenesis.

Methods: …
