During the past decades, anticancer immunotherapy has evolved from a promising therapeutic option to a robust clinical reality. Many immunotherapeutic regimens are now approved by the US Food and Drug Administration and the European Medicines Agency for use in cancer patients, and many others are being investigated as standalone therapeutic interventions or combined with conventional treatments in clinical studies. Immunotherapies may be subdivided into "passive" and "active" based on their ability to engage the host immune system against cancer. Since the anticancer activity of most passive immunotherapeutics (including tumor-targeting monoclonal antibodies) also relies on the host immune system, this classification …

Lung cancer is the leading cause of cancer related deaths. Common molecular drivers of lung cancer are mutations in receptor tyrosine kinases (RTKs) leading to activation of the phosphatidylinositol 3-kinase (PI3K)/Akt pro-growth, pro-survival signaling pathways. Myristoylated alanine rich C-kinase substrate (MARCKS) is a protein that has the ability to mitigate this signaling cascade by sequestering the target of PI3K, phosphatidylinositol (4,5)-bisphosphate (PIP2). As such, MARCKS has been implicated as a tumor suppressor, though there is some evidence that MARCKS may be tumor promoting in certain cancer types. Since the MARCKS function depends on its phosphorylation status, which impacts its subcellular …


Web Tool For Estimating The Cancer Hazard Rates In Aging., Tengiz Mdzinarishvili, Alexander Sherman, Oleg Shats, Simon Sherman Dec 2014

Web Tool For Estimating The Cancer Hazard Rates In Aging., Tengiz Mdzinarishvili, Alexander Sherman, Oleg Shats, Simon Sherman

Journal Articles: Eppley Institute

A computational approach for estimating the overall, population, and individual cancer hazard rates was developed. The population rates characterize a risk of getting cancer of a specific site/type, occurring within an age-specific group of individuals from a specified population during a distinct time period. The individual rates characterize an analogous risk but only for the individuals susceptible to cancer. The approach uses a novel regularization and anchoring technique to solve an identifiability problem that occurs while determining the age, period, and cohort (APC) effects. These effects are used to estimate the overall rate, and to estimate the population and individual …

Engineered Plga Nanoparticles For Delivery Of Sirna In Mcf-7 Breast Cancer Cells, Sydney Pong, Samit Shah, Vivek Gupta

Student Scholar Symposium Abstracts and Posters

Small interfering RNAs have been an emerging medical treatment for molecular based diseases as they are capable of gene-specific knockdown. Appropriate and efficient delivery remains one of the biggest challenges in the development of siRNA as an anti-cancer treatment. Nanoparticles containing siRNA were characterized and the efficacy of various peptides in the transfection of the nanoparticles were tested. A gene silencing assay was developed in order to determine the effect of siRNA therapeutics on gene functionality in breast cancer cells.

Molecular Insights Into Prostate Field Cancerization: Telomere Length, Egr-­‐1 Expression, And Regulation Of Mic-­‐1, Pdgf-­‐A, And Fas, Emily Frisch, Kristin Gabriel, Marco Bisoffi

Student Scholar Symposium Abstracts and Posters

The diagnosis of prostate cancer (adenocarcinoma) relies on screening for elevated prostate-specific antigen (PSA) in blood samples and on digital rectal examination (DRE). With high PSA levels and/or abnormal DRE, physicians recommend a biopsy, which often misses the location of the adenocarcinoma and results in false negatives. Previous studies have shown expression of the key transcription factor early growth response 1 (EGR-1), the pro-survival factor macrophage inhibitor cytokine 1 (MIC-1), and the growth stimulatory platelet derived growth factor A (PDGF-A) to be up-regulated in histologically normal tissues 1 centimeter adjacent to prostate adenocarcinomas. We hypothesize that tumors emerge from “field …


Suppression Of Invasion And Metastasis Of Triple-Negative Breast Cancer Lines By Pharmacological Or Genetic Inhibition Of Slug Activity., Giovanna Ferrari-Amorotti, Claudia Chiodoni, Fei Shen, Sara Cattelani, Angela Rachele Soliera, Gloria Manzotti, Giulia Grisendi, Massimo Dominici, Francesco Rivasi, Mario Paolo Colombo, Alessandro Fatatis, Bruno Calabretta Dec 2014

Suppression Of Invasion And Metastasis Of Triple-Negative Breast Cancer Lines By Pharmacological Or Genetic Inhibition Of Slug Activity., Giovanna Ferrari-Amorotti, Claudia Chiodoni, Fei Shen, Sara Cattelani, Angela Rachele Soliera, Gloria Manzotti, Giulia Grisendi, Massimo Dominici, Francesco Rivasi, Mario Paolo Colombo, Alessandro Fatatis, Bruno Calabretta

Department of Cancer Biology Faculty Papers

Most triple-negative breast cancers (TNBCs) exhibit gene expression patterns associated with epithelial-to-mesenchymal transition (EMT), a feature that correlates with a propensity for metastatic spread. Overexpression of the EMT regulator Slug is detected in basal and mesenchymal-type TNBCs and is associated with reduced E-cadherin expression and aggressive disease. The effects of Slug depend, in part, on the interaction of its N-terminal SNAG repressor domain with the chromatin-modifying protein lysine demethylase 1 (LSD1); thus, we investigated whether tranylcypromine [also known as trans-2-phenylcyclopropylamine hydrochloride (PCPA) or Parnate], an inhibitor of LSD1 that blocks its interaction with Slug, suppresses the migration, invasion, and metastatic …

The Impact Of Inflammatory And Immune Response-Related Genetic Variants On Prostate Cancer Risk Among Men Of African Descent., Dominique Zilpha Jones Dec 2014

The Impact Of Inflammatory And Immune Response-Related Genetic Variants On Prostate Cancer Risk Among Men Of African Descent., Dominique Zilpha Jones

Electronic Theses and Dissertations

Background: In the U.S., prostate cancer (PCA) metastasis is associated with a 5-yr survival rate of 29% and disproportionately affects men of African descent. Single nucleotide polymorphisms (SNPs) may serve as genetic markers to identify individuals at high risk of developing PCA. Methods: We examined main and joint effects of 119 inflammatory and immune response-associated SNPs among men of African descent (535 controls, 279 cases) via logistic regression (LR) and entropy-based-multi-factor dimensionality reduction (MDR) modeling. Results: MDR yielded highly synergistic [(TLR10, TLR6 and IRF3), (TLR2, IRAK4), (IL1R2, IL10, IL10RA)] interaction …


Modulation Of The Ovarian Cancer Humoral Response By Tumor-Derived Exosomes., Carolyn Denise Roberson Dec 2014

Modulation Of The Ovarian Cancer Humoral Response By Tumor-Derived Exosomes., Carolyn Denise Roberson

Electronic Theses and Dissertations

The pathogenesis of epithelial ovarian cancer is complicated by its diagnosis during the latter stages of the disease resulting from lack of symptoms or from presence of symptoms that mimic other conditions. Because of the often fatal prognosis by the time of actual detection, efforts are being made to better understand the host immune response to ovarian cancer. In this study, the contributions of the humoral immune response were investigated by focusing on the role of tumor-derived exosomes and their ability to modulate humoral immune responses. First, ovarian cancer patient-derived free circulating antibodies were investigated for immunoreactivity to patient antigen. …

Treatment Updates Regarding Anaplastic Oligodendroglioma And Anaplastic Oligoastrocytoma, Khurshid Ahmed Khan, Ahmed Nadeem Abbasi, Nasir Ali

Department of Radiation Oncology

Anaplastic Oligodendroglioma / Anaplastic Oligoastrocytoma (AO/AOA) is a WHO Grade-III primary brain tumor. These tumors comprise about 5 - 10% of all gliomas, which make them the third most common primary brain tumors after glioblastoma multiforme and astrocytomas. For many years standard of treatment remained Maximum Safe Resection (MSR) followed by Radiotherapy (RT). These tumors have also been known to be sensitive to alkylator-based chemotherapy particularly the subset having 1p/19q co-deletion signature. There is robust data showing that these tumors are responsive to chemotherapy in recurrent or progressive setting. Recently, up front chemotherapy has been added to standard post-surgery RT. …


Development And Characterization Of An Autologous Whole Cell Breast Cancer Vaccine, Samantha Leigh Kurtz Dec 2014

Development And Characterization Of An Autologous Whole Cell Breast Cancer Vaccine, Samantha Leigh Kurtz

Graduate Theses and Dissertations

Approximately 40,000 women will die from breast cancer in the United States in 2014. About 90% of these deaths will be due to metastases, rather than the primary tumor and majority of metastases are due to the recurrence and progression of non-metastatic disease. Current adjuvant treatments, such as chemotherapy and radiation, have severe side effects and may result in overtreatment and drug resistance.

Since greater than 90% of patients are diagnosed between stages I-III and have minimal residual disease after treatment, there is an opportunity to treat patients with an autologous breast cancer vaccine. Autologous vaccines under development have a …

Lung Cancer Survival Disparities In Nevada, Chima Osuoha

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lung cancer is the leading cause of cancer death in both men and women in the United States. Nevada shows moderate incidence rates of lung cancer for men but high rates for women. Little is known about the lung cancer experience and survival characteristics of the nearly 2000 new cases occurring every year in the State. The purpose of this study was to measure the extent to which geographic area of residency, gender, race, health insurance, social economic status (SES) and stage at diagnosis were associated with survival in patients diagnosed with lung cancer in Nevada. This was a retrospective …


Hyperthermia, Radiation And Chemotherapy: The Role Of Heat In Multidisciplinary Cancer Care., Mark Hurwitz, Md, Paul R. Stauffer Dec 2014

Hyperthermia, Radiation And Chemotherapy: The Role Of Heat In Multidisciplinary Cancer Care., Mark Hurwitz, Md, Paul R. Stauffer

Department of Radiation Oncology Faculty Papers

The compelling biologic basis for combining hyperthermia with modern cancer therapies including radiation and chemotherapy was first appreciated nearly half a century ago. Hyperthermia complements radiation as conditions contributing to radio-resistance generally enhance sensitivity to heat and sensitizing effects occur through increased perfusion/tumor oxygenation and alteration of cellular death pathways. Chemosensitization with hyperthermia is dependent on the particular mechanism of effect for each agent with synergistic effects noted for several commonly used agents. Clinically, randomized trials have demonstrated benefit including survival with the addition of hyperthermia to radiation or chemotherapy in treatment of a wide range of malignancies. Improvements in …

The Long Non-Coding Rna Pcat-1 Promotes Prostate Cancer Cell Proliferation Through Cmyc., John R. Prensner, Wei Chen, Sumin Han, Matthew K. Iyer, Qi Cao, Vishal Kothari, Joseph R. Evans, Karen E. Knudsen, Michelle T. Paulsen, Mats Ljungman, Theodore S. Lawrence, Arul M. Chinnaiyan, Felix Y. Feng

Department of Cancer Biology Faculty Papers

Long non-coding RNAs (lncRNAs) represent an emerging layer of cancer biology, contributing to tumor proliferation, invasion, and metastasis. Here, we describe a role for the oncogenic lncRNA PCAT-1 in prostate cancer proliferation through cMyc. We find that PCAT-1-mediated proliferation is dependent on cMyc protein stabilization, and using expression profiling, we observed that cMyc is required for a subset of PCAT-1-induced expression changes. The PCAT-1-cMyc relationship is mediated through the post-transcriptional activity of the MYC 3' untranslated region, and we characterize a role for PCAT-1 in the disruption of MYC-targeting microRNAs. To further elucidate a role for post-transcriptional regulation, we demonstrate …

Department of Cancer Biology Faculty Papers

Castration resistance is a major obstacle to hormonal therapy for prostate cancer patients. Although androgen independence of prostate cancer growth is a known contributing factor to endocrine resistance, the mechanism of androgen receptor deregulation in endocrine resistance is still poorly understood. Herein, the CAMK2N1 was shown to contribute to the human prostate cancer cell growth and survival through AR-dependent signaling. Reduced expression of CAMK2N1 was correlated to recurrence-free survival of prostate cancer patients with high levels of AR expression in their tumor. CAMK2N1 and AR signaling form an auto-regulatory negative feedback loop: CAMK2N1 expression was down-regulated by AR activation; while …


Inhibition Of Rac1 Gtpase Sensitizes Pancreatic Cancer Cells To Γ-Irradiation., Y Yan, Ashley L. Hein, Asserewou Etekpo, Katrina M. Burchett, Chi Lin, Charles A. Enke, Surinder K. Batra, Kenneth Cowan, M Ouellette Nov 2014

Inhibition Of Rac1 Gtpase Sensitizes Pancreatic Cancer Cells To Γ-Irradiation., Y Yan, Ashley L. Hein, Asserewou Etekpo, Katrina M. Burchett, Chi Lin, Charles A. Enke, Surinder K. Batra, Kenneth Cowan, M Ouellette

Journal Articles: Radiation Oncology

Radiation therapy is a staple treatment for pancreatic cancer. However, owing to the intrinsic radioresistance of pancreatic cancer cells, radiation therapy often fails to increase survival of pancreatic cancer patients. Radiation impedes cancer cells by inducing DNA damage, which can activate cell cycle checkpoints. Normal cells possess both a G1 and G2 checkpoint. However, cancer cells are often defective in G1 checkpoint due to mutations/alterations in key regulators of this checkpoint. Accordingly, our results show that normal pancreatic ductal cells respond to ionizing radiation (IR) with activation of both checkpoints whereas pancreatic cancer cells respond to IR with G2/M arrest …

Kimmel Cancer Center Faculty Papers

The p53 tumor suppressor protein plays a crucial role in influencing cell fate decisions in response to cellular stress. As p53 elicits cell cycle arrest, senescence or apoptosis, the integrity of the p53 pathway is considered a key determinant of anti-tumor responses. p53 can also promote autophagy, however the role of p53-dependent autophagy in chemosensitivity is poorly understood. VMY-1-103 (VMY), a dansylated analog of purvalanol B, displays rapid and potent anti-tumor activities, however the pathways by which VMY works are not fully defined. Using established prostate cancer cell lines and novel conditionally reprogrammed cells (CRCs) derived from prostate cancer patients; …

Nerve Growth Factor Regulates Neurolymphatic Remodeling During Corneal Inflammation And Resolution., Darci M. Fink, Alicia L. Connor, Philip M. Kelley, Maria M. Steele, Michael A. Hollingsworth, Richard M. Tempero Nov 2014

Nerve Growth Factor Regulates Neurolymphatic Remodeling During Corneal Inflammation And Resolution., Darci M. Fink, Alicia L. Connor, Philip M. Kelley, Maria M. Steele, Michael A. Hollingsworth, Richard M. Tempero

Journal Articles: Eppley Institute

The cellular and physiologic mechanisms that regulate the resolution of inflammation remain poorly defined despite their widespread importance in improving inflammatory disease outcomes. We studied the resolution of two cardinal signs of inflammation-pain and swelling-by investigating molecular mechanisms that regulate neural and lymphatic vessel remodeling during the resolution of corneal inflammation. A mouse model of corneal inflammation and wound recovery was developed to study this process in vivo. Administration of nerve growth factor (NGF) increased pain sensation and inhibited neural remodeling and lymphatic vessel regression processes during wound recovery. A complementary in vivo approach, the corneal micropocket assay, revealed that …

Role Of A Genetic Variant On The 15q25.1 Lung Cancer Susceptibility Locus In Smoking-Associated Nasopharyngeal Carcinoma, Xuemei Ji, Weidong Zhang, Jiang Gui, Xia Fan, Weiwei Zhang, Yafang Li, Guangyu An, Dakai Zhu, Qiang Hu

Dartmouth Scholarship

Background: The 15q25.1 lung cancer susceptibility locus, containing CHRNA5, could modify lung cancer susceptibility and multiple smoking related phenotypes. However, no studies have investigated the association between CHRNA5 rs3841324, which has been proven to have the highest association with CHRNA5 mRNA expression, and the risk of other smoking-associated cancers, except lung cancer. In the current study we examined the association between rs3841324 and susceptibility to smoking-associated nasopharyngeal carcinoma (NPC).

Methods: In this case-control study we genotyped the CHRNA5 rs3841324 polymorphism with 400 NPC cases and 491 healthy controls who were Han Chinese and frequency-matched by age (±5 years), gender, and …

Experimental Study Of Needle-Tissue Interaction Forces: Effect Of Needle Geometries, Insertion Methods And Tissue Characteristics., Shan Jiang, Pan Li, Yan Yu, Jun Liu, Zhiyong Yang

Department of Radiation Oncology Faculty Papers

A thorough understanding of needle-tissue interaction mechanics is necessary to optimize needle design, achieve robotically needle steering, and establish surgical simulation system. It is obvious that the interaction is influenced by numerous variable parameters, which are divided into three categories: needle geometries, insertion methods, and tissue characteristics. A series of experiments are performed to explore the effect of influence factors (material samples n=5 for each factor) on the insertion force. Data were collected from different biological tissues and a special tissue-equivalent phantom with similar mechanical properties, using a 1-DOF mechanical testing system instrumented with a 6-DOF force/torque (F/T) sensor. The …
