Chronic Inflammation As A Result Of Hepatitis C Virus Infection: A Review Of The Literature, Samantha L. Lane 2015 DePaul University

Chronic Inflammation As A Result Of Hepatitis C Virus Infection: A Review Of The Literature, Samantha L. Lane

DePaul Discoveries

Approximately 170 million people are infected with Hepatitis C virus (HCV) worldwide5,6. It is estimated that roughly 80% of those infected suffer from persistent infection with the virus; this persistence of infection is progressive, and over time can lead to fibrosis, cirrhosis, and hepatocellular carcinoma7. Chronic inflammation and apoptotic deregulation are both hallmarks of chronic HCV infection, and many molecular pathways are initiated in both the innate and adaptive immune responses during infection with this viral pathogen. The aim of this review was to survey some of the major molecular mechanisms responsible for the induction of chronic ...


Light Microscopy Reflection Focusing Cells And Coverglass, George McNamara 2015 M.D. Anderson Cancer Center

Light Microscopy Reflection Focusing Cells And Coverglass, George Mcnamara

George McNamara

Light Microscopy Reflection Focusing Cells and Coverglass 20150520Wed

Many light microscopes have the capability of using camera based brightfield, phase contrast, or fluorescence to find the most contrasty specimen focus. When I worked for UIC (1992-1997) we offered this with a combination of Ludl MAC2000 controller, Z-drive, video card thingy, and video camera (most customers at the time used analog video cameras).

Many automated light microscopes now have clever -- and pricey -- autofocus systems based on an NIR LED structured illumination reflecting light off the bottom of the coverglass.

I encourage a simpler approach - my hardware details are in the text ...


Environmental Stimuli And Intragenerational Epigenetics, Nicholas J. Napier 2015 Wofford College

Environmental Stimuli And Intragenerational Epigenetics, Nicholas J. Napier

Student Scholarship

Epigenetics is the study of any change in gene expression that is not mediated by DNA sequence. The effects of environmental stimuli on epigenetic changes have been studied extensively in recent years. Multiple reviews have provided comprehensive summations of the effects of environmental stimuli on transgenerational epigenetic changes, but few reviews have focused upon environment-induced intragenerational epigenetic changes. This review will summarize current knowledge of the intragenerational epigenetic changes that are induced by two groups of well-studied environmental stimuli: nutritional deficiencies and carcinogens. This survey of intragenerational epigenetic changes will focus upon the mechanisms behind them, the disorders associated with ...


Exploring Egr-1 As A Master Regulator Of Prostate Field Cancerization, Kristin Gabriel, Marco Bisoffi 2015 Chapman University

Exploring Egr-1 As A Master Regulator Of Prostate Field Cancerization, Kristin Gabriel, Marco Bisoffi

Student Research Day Abstracts and Posters

Field cancerization denotes the presence of molecular aberrations (genetic, epigenetic, biochemical) in structurally intact cells residing in histologically normal tissues adjacent to tumors. Markers of field cancerization in prostate tissues have the potential to improve the clinical management of this malignancy through their potential to act as indicators of early disease and to serve as molecular targets for early intervention. However, for this, a detailed understanding of the functional pathways underlying field cancerization is necessary. We have recently identified four protein markers of prostate field cancerization, i.e. the key transcription factor early growth response 1 (EGR-1), the lipogenic enzyme ...


Prostate Field Cancerization – Thinking Outside The Tumor, Dor Shoshan 2015 Chapman University

Prostate Field Cancerization – Thinking Outside The Tumor, Dor Shoshan

Student Research Day Abstracts and Posters

Analysis of tumor adjacent tissue is assumed to reveal a temporal record of molecular pathways that define oncogenesis. The present study determines expression of the key transcription factor and potential marker of field cancerization early growth response 1 (EGR-1) in human prostate tissues derived from prostatectomies and biopsies. Expression was detected using immunofluorescence and quantified using ImageJ software. Accordingly, EGR-1 expression was similar in cancerous and in histologically normal adjacent tissues from prostatectomy and biopsy specimens. EGR-1 could be exploited as pre-surgical disease indicator in false negative biopsies, identify areas of repeat biopsy, and add molecular information to surgical margins.


Effect Of Curcumin Analog Ca27 On Androgen Receptor Translocation In Prostate Cancer Cells, Lijah Vann Gardner 2015 Chapman University

Effect Of Curcumin Analog Ca27 On Androgen Receptor Translocation In Prostate Cancer Cells, Lijah Vann Gardner

Student Research Day Abstracts and Posters

The androgen receptor (AR) plays an essential role in promoting the development and progression of metastatic prostate cancer and represents an important molecular target for therapeutic intervention. We have recently described a series of synthetic analogs of the natural product diferuloylmethane (curcumin), some of which induce the down-regulation of AR expression in prostate cancer cells by an as yet largely unknown mechanism of action. While such analogs may in the long term be lead structures for the development of therapeutic drugs, we hypothesize here that they represent ideal molecular probes to identify the mechanism(s) of action for AR down-regulation ...


Analyzation Of Metabolic Reprogramming In Drug-Resistant Mcf-7 Cells, Derick Han, Ho Leung, Andrew Vo 2015 Keck Graduate Institute

Analyzation Of Metabolic Reprogramming In Drug-Resistant Mcf-7 Cells, Derick Han, Ho Leung, Andrew Vo

Student Research Day Abstracts and Posters

The Warburg effect states that cancer cells mainly receive their energy from anaerobic glycolysis. Thus, mitochondria play a different role in the metabolism of cancer cells as opposed to normal, healthy cells. In chemotherapy, there is always a chance of the cancer regressing. Making drug-resistant cancer cells to analyze their metabolism may change how cancer is treated. This study aimed to create drug-resistant MCF-7 cell lines with doxorubicin in order to determine the metabolic changes that have occurred in the process of becoming resistant to drug treatments.


Il-15 Induces Irisin Expression In Skeletal Muscle, James Krolopp, Shantae M. Thornton, Marcia J. Abbott 2015 Chapman University

Il-15 Induces Irisin Expression In Skeletal Muscle, James Krolopp, Shantae M. Thornton, Marcia J. Abbott

Student Research Day Abstracts and Posters

With the rising rate of obesity, brown adipose tissue(BAT) biology has become an area of interest. BAT is unique because it contains many mitochondria that require more energy than white adipose tissue. Increasing the amount of BAT can create a larger caloric need that can positively affect body composition. IL-15, a myokine, has been shown to activate mitochondrial activity resulting in decreases in fat mass and possibly increase BAT. The purpose of this study was to determine if IL-15 is involved in mediating genes positively associated with BAT. A skeletal muscle cell line was used in these studies and ...


Clinical Applications Of A Combination Chemotherapy Using 8-Chloro Camp And 8-Chloro Adenosine, Erik Munoz, Andrea Saich, Andrew Cox, Yu-An Peter Chang 2015 Chapman University

Clinical Applications Of A Combination Chemotherapy Using 8-Chloro Camp And 8-Chloro Adenosine, Erik Munoz, Andrea Saich, Andrew Cox, Yu-An Peter Chang

Student Research Day Abstracts and Posters

Dr. Cho-Chung from the NIH first thought to use halogenated cAMP derivatives as competitive inhibitors of cAMP to slow down cancer cell mitosis. While the iodine and bromine substituted versions showed very little therapeutic actions, 8-Chloro cAMP has been shown to have strong anti-cancer effects. This has been shown in the phase II clinical trials this drug has undergone. However, these trials have had issues with solubility and toxicity. The drug is similar to vitamin C and is excreted quickly. Scientists tried to overcome this by using a peristaltic pump to give patients a continuous dosage, but this proved too ...


Reverse Gyrase Is Not Necessary For Survival Of Hyperthermophilic Archaeon Pyrococcus Furiosus, Farshid Taghizadeh, Michael S. Bartlett 2015 Portland State University

Reverse Gyrase Is Not Necessary For Survival Of Hyperthermophilic Archaeon Pyrococcus Furiosus, Farshid Taghizadeh, Michael S. Bartlett

Student Research Symposium

Reverse gyrase is the only known topoisomerase enzyme with positive supercoiling activity on covalently-closed DNA. This positive supercoiling is required to prevent DNA from denaturation at high temperatures. The gene that codes for this protein is present in all hyperthermophiles and absent from all mesophilic and thermophilic genomes, suggesting that this enzyme is the only hyperthermophile-specific protein. To investigate if this protein is vital for the cells, we knocked out its gene from the genome of living organism Pyrococcus furiosus. Pyrococcus furiosus is a hyperthermophilic archaeon that grows between 70°C to 103°C with an optimum growth temperature of ...


Deciphering The Functional Collaboration Of Mid And Bric-A-Brac 2 As Potential Regulators Of Cellular Proliferation Within Adult Drosophila Ovaries, Petra Visic 2015 University of Southern Mississippi

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 ...


Effect Of Cmvil-10 On Exosome Production By Human Breast Cancer Cells, Susanna N. Basappa 2015 University of San Francisco

Effect Of Cmvil-10 On Exosome Production By Human Breast Cancer Cells, Susanna N. Basappa

Undergraduate Honors Theses

Human cytomegalovirus (HCMV) is a ubiquitous virus that infects 70-90% of the general population, primarily the immunocompromised, but has been implicated in several forms of cancer, including breast cancer. Breast cancer is the second leading cause of cancer related deaths in women in North America, usually from metastasis. Exosomes are 30-100nm vesicles produced by most cells which carry protein and RNA to cells in their microenvironment. The aim of this study is to investigate the impact of HCMV-infection of a secreted viral cytokine, cmvIL-10, on exosome production by highly metastatic breast cancer cells.

MDA-MB-231 cells were cultured in vitro, and ...

Characterization Of A Novel Clade Of Transporters In Phytophthora, Stephanie Padula, Paul F. Morris Dr, Howard Casey Cromwell Dr., Menaka Ariyaratne, Andrew Wagner 2015 Bowling Green State University - Main Campus

Characterization Of A Novel Clade Of Transporters In Phytophthora, Stephanie Padula, Paul F. Morris Dr, Howard Casey Cromwell Dr., Menaka Ariyaratne, Andrew Wagner

Honors Projects

The oomycete Phytophthora parasitica has a worldwide distribution and is an economically important pathogen of more than 100 species4. RNA-seq analysis showed that one gene, PPTG_16698 has the 5th highest level of expression of all transport proteins in the zoospore stage, and is highly conserved throughout Phytophthora species. This project attempts to characterize the important biological role that PPTG_16698 plays in P. parasitica and other oomycetes. Three strategies have been implemented to accomplish this goal: growth analysis by heterologous expression in yeast, metabolite analysis in yeast, and construction of a GFP fusion protein to enable localization of the ...


Efficient In Vitro Development Of Photoreceptors From Human Pluripotent Stem Cells, Joseph C. Reynolds 2015 Dominican University of California

Efficient In Vitro Development Of Photoreceptors From Human Pluripotent Stem Cells, Joseph C. Reynolds

Master's Theses and Capstone Projects

Degeneration of the rod and cone photoreceptors in the human retina is among the most common causes of blindness. Replacing these damaged photoreceptors may help to restore vision. Repairing the damaged retina relies on the insertion of new, healthy cells. Embryonic stem (ES) cells and induced pluripotent stem (iPS) cells are two possible sources of photoreceptors to restore vision. Previous data shows that human ES cells and iPS cells can be differentiated into photoreceptors and transplanted into the eye to restore some vision. However, this process is inefficient, and costly. Here, we show a new method for inducing photoreceptor production ...

Development Of Quantitative Tools For The Characterization And Analysis Of The Blood Brain Barrier In Normal And Mps Iiib Mice, Sara M. Rigney 2015 Dominican University of California

Development Of Quantitative Tools For The Characterization And Analysis Of The Blood Brain Barrier In Normal And Mps Iiib Mice, Sara M. Rigney

Master's Theses and Capstone Projects

The Blood Brain Barrier (BBB) functions to control homeostasis within the central nervous system (CNS) via strict control over the passage of molecules into and out of the brain. The goal of this barrier is to protect the CNS from harmful external factors while allowing entry of essential nutrients and removal of metabolic byproducts. This restrictive nature of the BBB is due to the protein network at the borders of adjoining cerebral endothelial cells known as the tight junctions (TJs) and the relationship of other supporting cells and proteins such as astrocytes, pericytes, microglia, and the basement membrane and extracellular ...
