Large Scale Matrix Degradation By Stromal Cells Independent Of Invadopodia, Hong Cao, Robbin Eppinga, Eugene W. Krueger, Jing Chen, Mark A. Mcniven
Large Scale Matrix Degradation By Stromal Cells Independent Of Invadopodia, Hong Cao, Robbin Eppinga, Eugene W. Krueger, Jing Chen, Mark A. Mcniven
Faculty Work Comprehensive List
Invadopodia are actin-rich structures at the base of many neoplastic cells that sequester matrix metalloproteases that act to degrade the surrounding stroma to facilitate the invasive process. Conventional invadopodia are dependent upon Src kinase and the large GTPase dynamin 2 (Dyn 2). Whether invadopodia are the only mechanism by which cells degrade matrix is unclear. We have observed that cells of mesenchymal origin degrade matrix in an unique way different from tumor cells. The HYPOTHESIS of this study is that fibroblasts, and other cells of mesenchymal origin, degrade matrix by a mechanism distinct from that of epithelial-based tumor cells. The …

We demonstrate the first use of the nullomer (absent sequences) approach to drug discovery and development. Nullomers are the shortest absent sequences determined in a species, or group of species. By identifying the shortest absent peptide sequences from the NCBI databases, we screened several potential anti-cancer peptides. In order to improve cell penetration and solubility we added short poly arginine tails (5Rs), and initially solubilized the peptides in1M trehalose. The results for one of the absent sequences 9R (RRRRRNWMWC), and its scrambled version 9S1R (RRRRRWCMNW) are reported here. We refer to these peptides derived from nullomers as PolyArgNulloPs. A control …
A Study On The Function Of 14-3-3sigma In Regulating Cancer Energy Metabolism, Liem M. Phan, Liem M. Phan
A Study On The Function Of 14-3-3sigma In Regulating Cancer Energy Metabolism, Liem M. Phan, Liem M. Phan
Dissertations & Theses (Open Access)
Metabolic reprogramming has been shown to be a major cancer hallmark providing tumor cells with significant advantages for survival, proliferation, growth, metastasis and resistance against anti-cancer therapies. Glycolysis, glutaminolysis and mitochondrial biogenesis are among the most essential cancer metabolic alterations because these pathways provide cancer cells with not only energy but also crucial metabolites to support large-scale biosynthesis, rapid proliferation and tumorigenesis. In this study, we find that 14-3-3σ suppresses all these three metabolic processes by promoting the degradation of their main driver, c-Myc. In fact, 14-3-3s significantly enhances c-Myc poly-ubiquitination and subsequent degradation, reduces c-Myc transcriptional activity, and down-regulates …
Characterization Of A Tumour Suppressor Function Of Ranbpm, Elnaz Atabakhsh
Characterization Of A Tumour Suppressor Function Of Ranbpm, Elnaz Atabakhsh
Electronic Thesis and Dissertation Repository
Ran-binding protein M (RanBPM) is an evolutionarily conserved nucleocytosolic protein that has been proposed to regulate various cellular processes, including protein stability, gene expression, receptor-mediated signalling pathways, cell adhesion, development, and apoptosis. Despite the multitude of functions attributed to RanBPM however, little is known regarding the precise mechanisms by which RanBPM executes these cellular roles. In this work, we seek to address this matter by describing functions for RanBPM in the regulation of apoptotic and pro-survival signalling pathways, and in cellular transformation.
We first identify RanBPM as a pro-apoptotic protein that regulates the activation of the intrinsic apoptotic signalling pathway …

Polysaccharopeptide Enhances The Anticancer Activity Of Doxorubicin And Etoposide On Human Breast Cancer Cells Zr-75-30, Jennifer Man-Fan Wan, Wai Hung Sit, Jimmy Chun Yu Louie
Jimmy Chun Yu Louie
In search of natural bioactive microbial compounds with adjuvant properties, we have previously showed that the polysaccharopeptide (PSP), isolated from Chinese medicinal mushroom Coriolus versicolor, was able to enhance the cytotoxicity of certain S-phase targeted-drugs on human leukemic HL-60 cells via some cell-cycle and apoptotic-dependent pathways. The present study aimed to investigate whether the synergism of mechanisms of PSP with certain chemotherapeutic drugs also applies to human breast cancer. PSP treatment enhanced the cytotoxicity of doxorubicin (Doxo), etoposide (VP-16) but not cytarabine (Ara-C). Bivariate bromodeoxyuridine (BrdUrd)/DNA flow cytometry analysis estimated a longer DNA synthesis time (Ts) for the PSP treated …
Maternal Consumption Of Canola Oil Suppressed Mammary Gland Tumorigenesis In C3(1) Tag Mice Offspring, Gabriela Ion, Juliana A. Akinsete, W. Elaine Hardman
Maternal Consumption Of Canola Oil Suppressed Mammary Gland Tumorigenesis In C3(1) Tag Mice Offspring, Gabriela Ion, Juliana A. Akinsete, W. Elaine Hardman
Gabriela Ion
Background: Maternal consumption of a diet high in omega 6 polyunsaturated fats (n-6 PUFA) has been shown to increase risk whereas a diet high in omega 3 polyunsaturated fats (n-3 PUFA) from fish oil has been shown to decrease risk for mammary gland cancer in female offspring of rats. The aim of this study was to determine whether increasing n-3 PUFA and reducing n-6 PUFA by using canola oil instead of corn oil in the maternal diet might reduce the risk for breast cancer in female offspring. Methods: Female SV 129 mice were divided into two groups and placed on …

The Epigenomic Viewpoint On Cellular Differentiation Of Myeloid Progenitor Cells As It Pertains To Leukemogenesis, Vincent E. Sollars
The Epigenomic Viewpoint On Cellular Differentiation Of Myeloid Progenitor Cells As It Pertains To Leukemogenesis, Vincent E. Sollars
Vincent E Sollars
The new millennium has brought with it a surge of research in the field of epigenetics. This has included advances in our understanding of stem cell characteristics and mechanisms of commitment to cell lineages prior to differentiation. The nature of stem cells is similar to that of malignant cells in that they have unlimited self-renewal and protection from apoptosis, leading researchers to suspect that stem cells are the target of oncogenesis. This review will explore the idea of how epigenetic control of gene expression may contribute to mechanisms controlling differentiation of myeloid progenitor cells and its importance to our understanding …

Expression And Function Of Hypoxia Inducible Factor-1 Alpha In Human Melanoma Under Non-Hypoxic Conditions, Caroline N. Mills, Sandeep S. Joshi, Richard M. Niles
Richard M. Niles
Background Hypoxia inducible factor-1 alpha (HIF-1α) protein is rapidly degraded under normoxic conditions. When oxygen tensions fall HIF-1α protein stabilizes and transactivates genes involved in adaptation to hypoxic conditions. We have examined the normoxic expression of HIF-1α RNA and protein in normal human melanocytes and a series of human melanoma cell lines isolated from radial growth phase (RGP), vertical growth phase (VGP) and metastatic (MET) melanomas. Results HIF-1α mRNA and protein was increased in RGP vs melanocytes, VGP vs RGP and MET vs VGP melanoma cell lines. We also detected expression of a HIF-1α mRNA splice variant that lacks part …
Combinatorial Analysis Of Tumorigenic Micrornas Driving Prostate Cancer, William Budd
Combinatorial Analysis Of Tumorigenic Micrornas Driving Prostate Cancer, William Budd
Theses and Dissertations
Prostate cancer is the leading non-cutaneous malignancy affecting men in the United States. One in every six men will be affected by prostate cancer. Due to the high incidence of prostate cancer, there is a need to develop biomarkers capable of identifying tumors from benign prostatic lesions. miRNAs are small molecules that regulate protein translation and impact cellular integrity when dysregulated. It is widely thought that miRNAs have the potential to serve as biomarkers. This study utilizes a unique combinatorial analysis of miRNA dysregulation to identify key miRNAs involved in prostate tumor initiation, progression and metastasis. Numerous dysregulated miRNAs potentially …
Platelets And Anti-Angiogenic Resistance In Ovarian Carcinoma, Justin N. Bottsford-Miller
Platelets And Anti-Angiogenic Resistance In Ovarian Carcinoma, Justin N. Bottsford-Miller
Dissertations & Theses (Open Access)
Background: Resistance to targeted anti-angiogenic therapy is a growing clinical concern given the disappointing clinical impact of anti-angiogenic. Platelets represent a component of the tumor microenvironment that are implicated in metastasis and represent a significant reservoir of angiogenic regulators. Thrombocytosis has been shown to be caused by malignancy and associated with adverse clinical outcomes, however the causal connections between these associations remain to be identified.
Materials and Methods: Following IRB approval, patient data were collected on patients from four U.S. centers and platelet levels through and after therapy were considered as indicators of recurrence of disease. In vitro effects of …

Cancer is a leading cause of death of men and women worldwide. Tumor cell motility contributes to metastatic invasion that causes the vast majority of cancer deaths. Extracellular receptors modified by α2,3-sialic acids that promote this motility can serve as ideal chemotherapeutic targets. For example, the extracellular domain of the mucin receptor podoplanin (PDPN) is highly O-glycosylated with α2,3-sialic acid linked to galactose. PDPN is activated by endogenous ligands to induce tumor cell motility and metastasis. Dietary lectins that target proteins containing α2,3-sialic acid inhibit tumor cell growth. However, anti-cancer lectins that have been examined thus far target receptors …

Don C. Iverson
Background Numerous studies have shown that the majority of women overestimate both their own risk and the populations’ risk of developing breast cancer. A number of factors have been found to correlate with perceived risk. Methods This paper reports on a telephone survey of a nationally representative sample of approximately 3,000 Australian women aged 30 to 69 years, conducted in 2007, and compares the findings with those of a similar survey conducted in 2003. Results There was a clear tendency for respondents to overestimate the proportion of women who will develop breast cancer during their lifetime. Approximately half the respondents …
Rok And Rac Mediation Of Prl-1 Function In The Wings Of Drosophila Melanogaster, Rosemary Dinkins
Rok And Rac Mediation Of Prl-1 Function In The Wings Of Drosophila Melanogaster, Rosemary Dinkins
Honors Program Theses
By the time a cancer metastasizes it has reached its most deadly stage. It therefore is essential that the underpinning mechanisms promoting metastasis are understood. Phosphatases of regenerating liver (PRL) have been repeatedly connected to cancer metastasis when overexpressed. However, little is yet known about the normal PRL function and biological pathways let alone the PRL pathway promoting metastasis. The current study explores the relationship between PRL-1 and two other genes, ROK and Rac,that have also been implicated in cell migration and metastasis. Increased PRL-1 function in conjunction with increased or decreased Rac function was forced to the dorsal half …

UCHC Articles - Research
It has been a decade since the introduction of SH2 profiling, a modular domain-based molecular diagnostics tool. This review covers the original concept of SH2 profiling, different analytical platforms, and their applications, from the detailed analysis of single proteins to broad screening in translational research. Illustrated by practical examples, we discuss the uniqueness and advantages of the approach as well as its limitations and challenges. We provide guidance for basic researchers and oncologists who may consider SH2 profiling in their respective cancer research, especially for those focusing on tyrosine phosphoproteomics. SH2 profiling can serve as an alternative phosphoproteomics tool to …

Increased Geranylgeranylated K-Ras Contributes To Antineoplastic Effects Of Farnesyltransferase Inhibitors., Mandy A. Hall
Dissertations & Theses (Open Access)
The Ras family of small GTPases (N-, H-, and K-Ras) is a group of important signaling mediators. Ras is frequently activated in some cancers, while others maintain low level activity to achieve optimal cell growth. In cells with endogenously low levels of active Ras, increasing Ras signaling through the ERK and p38 MAPK pathways can cause growth arrest or cell death. Ras requires prenylation – the addition of a 15-carbon (farnesyl) or 20-carbon (geranylgeranyl) group – to keep the protein anchored into membranes for effective signaling. N- and K-Ras can be alternatively geranylgeranylated (GG’d) if farnesylation is inhibited but are …
Defeating Cytoplasmic Sequestration Of P53 In Human Breast Cancer Cells; Is Mortalin Involved?, Sarah Yunes
Defeating Cytoplasmic Sequestration Of P53 In Human Breast Cancer Cells; Is Mortalin Involved?, Sarah Yunes
Honors Theses and Capstones
Cytoplasmic sequestration of p53, possibly caused by p53 interacting with mortalin, can prevent p53 from functioning in DNA repair and apoptosis, causing aberrant growth. This project treated SKBR3 breast cancer cells with MKT-077, a dye that is a competitive binder to mortalin to see if it would result in the release of p53 from the cytoplasm and restoration of p53 function. Treatment resulted in partial translocation of a protein suspected to be p53 to the nucleus and apoptosis initiated at the mitochondria.
Matrix Metalloproteinase Genes Are Transcriptionally Regulated By E2f Transcription Factors: A Link Between Cell Cycle Control And Metastatic Progression, Jacqueline Lea Johnson
Matrix Metalloproteinase Genes Are Transcriptionally Regulated By E2f Transcription Factors: A Link Between Cell Cycle Control And Metastatic Progression, Jacqueline Lea Johnson
USF Tampa Graduate Theses and Dissertations
The RbµE2F transcriptional regulatory pathway plays a critical role in the cell cycle. Rb is inactivated through multiple waves of phosphorylation, mediated mainly by cyclin D and cyclin E associated kinases. Once Rb is inactivated, cells can enter Sµphase. Collectively, three Rb family members and ten E2F proteins coordinate every additional stage of the cell cycle, from quiescence to mitosis. However the RbµE2F pathway is frequently altered in cancer. Aside from cell proliferation, the RbµE2F pathway regulates other essential cellular processes including apoptosis, cell differentiation, angiogenesis and DNA damage repair pathways, but its role in invasion and cancer progression is …

The Role Of Tumor Suppressors, Ship And Rb, In Immune Suppressive Cells, Michelle Marie Collazo Ruiz
The Role Of Tumor Suppressors, Ship And Rb, In Immune Suppressive Cells, Michelle Marie Collazo Ruiz
USF Tampa Graduate Theses and Dissertations
Regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSC) have been extensively studied in the past 30-40 years. Their potent suppressive capacity shown in several pathological and clinical settings, such as cancer and transplantation, has made it evident that better understanding their development and function is critical.
Specifically, Tregs play a pivotal role in preventing autoimmunity, graft-versus-host disease (GvHD), and organ graft rejection. We previously demonstrated that germline or induced SH2 domain-containing inositol 5-phosphatase (SHIP) deficiency in the host abrogates GvHD. Here we show that SHIP-deficiency promotes an increase of FoxP3+ cells in both the CD4+CD25+ and the CD4+CD25- T …
Compositional Determinants Of The Pharmacological Actions Of Heparins, Angel Lee Gray-Shah
Compositional Determinants Of The Pharmacological Actions Of Heparins, Angel Lee Gray-Shah
Dissertations
This dissertation primarily focuses on how differences in molecular weight (MW) and structural composition affect the pharmacological activity of heparin and its derivatives. Heparins are a mixture of glycosaminoglycans chains which are used to prevent thrombosis in a number of clinical indications. Heparins promote the inhibition of blood coagulation via their plasmatic cofactors antithrombin (AT) and heparin cofactor II (HCII).
In these studies, various heparins with molecular weights ranging from 2.6 to 16.5 kDa were investigated. Not only the molecular weight but also the oligosaccharide composition greatly varied in these agents. One of the major objectives of this research was …
Modulation Of Anti-Tumor Immune Response By Tgf-Β-Inducible Early Gene 1 (Tieg1), Andi Cani
Modulation Of Anti-Tumor Immune Response By Tgf-Β-Inducible Early Gene 1 (Tieg1), Andi Cani
Wayne State University Theses
Cancer immunotherapy has had limited clinical efficacy partly because regulatory T cells (Treg) suppress the immune response to tumor-associated antigens. Inducible regulatory T cells (iTreg), which are converted from naïve CD4 T cells by TGF-β, an abundant cytokine in the tumor microenvironment, may contribute to this immune suppression. Induction of Foxp3 by TGF-β is mediated by the transcription factor TIEG1 and abrogation of this protein prevents Foxp3 expression. We are testing the hypothesis that blockade of TIEG1 to prevent iTreg conversion will enhance immune response in DNA vaccination to the tumor associated antigen Her-2. Wild type and TIEG1 knockout mice …

I chose to do a project related to cancer for my Painting 1 class. Using oil paint, I wanted to create a more symbolic representation of cancer. So I made a cloud-like, cancerous mass with streaks of chaotic color swirling around a central face. The face represents any person affected by cancer and has had to “shut down” their emotions in order to function. I wanted the skin texture to be almost metallic as if it is metal armor or robotic-like, to support the idea of “shutting down” one’s emotions. The blank expression also portrays this idea.

Chloroform Fraction Of Centratherum Anthelminticum (L.) Seed Inhibits Tumor Necrosis Factor Alpha And Exhibits Pleotropic Bioactivities: Inhibitory Role In Human Tumor Cells, Dr Syam Mohan
Syam Mohan
We investigated the antioxidant potential, cytotoxic effect, and TNF-α inhibition activity with NF-κB activation response in a chloroformfraction of Centratherum anthelminticum seeds (CACF). The antioxidant property of CACF was evaluated with DPPH, ORAC, and FRAP assays, which demonstrated significant antioxidant activity. The cytotoxicity of CACF was tested using theMTT assay; CACF effective inhibitory concentrations (IC50) for A549, PC-3, MCF-7, and WRL-68 cells were 31.42 ± 5.4, 22.61 ± 1.7, 8.1±0.9, and 54.93±8.3 μg/mL, respectively. CACF effectively and dose-dependently inhibited TNF-α release, in vitro and in vivo. CACF inhibited TNF-α secretion in stimulated RAW264.7macrophage supernatants with an IC50 of 0.012 μg/mL, …
