The Electrochemical Detection Of Interleukin-8, Cancer Biomarker, Based On A Gold Nanoparticle Platform And Its Political Implications, Jaimee Doucette

Pell Scholars and Senior Theses

Herein we report on an ultrasensitive immunosensor based on glutathione protected gold nanoparticle (GSH-AuNP) for the electrochemical detection of interleukin 8 (IL-8), cancer biomarker in calf serum and proof of concept IL-8 detection in HNSCC cells. GSH-AuNP were bioconjugated to the primary antibodies (Ab1) and used to capture human IL-8 in a sandwich electrochemical immunoassay coupled to horseradish peroxidase enzyme labels. Using the optimized concentrations of the primary (Ab1) and secondary antibodies (Ab2), two sensor approaches were used to measure ultra low (≤ 500 fg mL-1) and elevated levels of IL-8. Biotinylated Ab2 bound to streptavidin HRP with 14-16 labels …

Heat Shock Proteins As Novel Cancer Therapeutics: Targeting The Hallmarks Of Cancer, Chao Li

Theses and Dissertations

Molecular chaperones, commonly known as heat shock proteins (HSPs), are essential for mammalian cells to maintain homeostasis, and HSPs function by inducing an ATPase-coupled structural change, followed by interactions with diverse co-chaperones and over 200 client proteins implicated in many critical signaling networks. These highly expressed HSPs participate in the onset and progression of several human diseases including cancer, and their connection with tumorigenesis has facilitated research and clinical trials related to targeting HSPs as a novel anti-tumor therapy. The predominant mechanism of chaperone inhibition is through either disruption of the HSP association with client protein or an altered binding …

Nanomaterials And Block Copolymers For Overcoming Multidrug Resistance In Cancer, Wesley Livingstone

Loma Linda University Electronic Theses, Dissertations & Projects

The development of multidrug resistance in cancer is one of the leading causes for decreased chemotherapy efficacy and is particularly threatening to aggressive cancers such as that of the pancreas. In cancers where chemotherapy is amongst the few treatment options, it is crucial to develop chemotherapeutics that either bypass or control the development of multidrug resistance. Polymeric nanomaterials such as Pluronics® are of current interest due to their ability to perform these functions in addition to enhancing pro-apoptotic mechanisms. Using the respectively known chemosensitive and chemoresistant pancreatic adenocarcinoma cell lines MiaPaCa-2 and PANC-1, an in vitro analysis of the synergistic …

Dance/Movement Therapy In Inpatient Hematological Cancer Treatment, Megan Hall

Creative Arts Therapies Theses

This quasi-experimental, mixed methods study examined the effects of dance/movement therapy on three types of outcomes (quality of life, anxiety and depression, and coping methods) for adult cancer inpatients who received treatment for a hematological cancer diagnosis. It was hypothesized that if hematological cancer patients participated in three or more dance/movement therapy sessions, then they would find a greater quality of life, decreased feelings of anxiety and depression, and an improvement in coping methods. Those patients who participated in three or more dance/movement therapy sessions while in the hospital formed the intervention group, and those who did not formed the …

Atm Signaling To Tsc2: Mechanisms And Implications For Cancer Therapy, Angela Alexander

Dissertations & Theses (Open Access)

Ataxia telangiectasia mutated (ATM) is a critical component of the cellular response to DNA damage, where it acts as a damage sensor, and signals to a large network of proteins which execute the important tasks involved in responding to the damage, namely inducing cell cycle checkpoints, inducing DNA repair, modulating transcriptional responses, and regulating cell death pathways if the damage cannot be repaired faithfully. We have now discovered that an additional novel component of this ATM-dependent damage response involves induction of autophagy in response to oxidative stress. In contrast to DNA damage-induced ATM activation however, oxidative stress induced ATM, occurs …

Rna Interference For Improving The Outcome Of Islet Transplantation And Polymeric Micelle‑Based Nanomedicine For Cancer Therapy, Feng Li

Theses and Dissertations (ETD)

Ex vivo gene transfer has been used to improve the outcome of islet transplantation for treating type I diabetes. RNA interference is an effective approach for reducing gene expressions at the mRNA level. The application of RNA interference to improve the outcome of islet transplantation was reviewed in Chapter 2, where I summarized biological obstacles to islet transplantation, various types of RNAi techniques, combinatorial RNAi in islet transplantation, and different delivery strategies.

Upregulation of inducible nitric oxide synthase (iNOS) and subsequent product of radical nitric oxide (NO) impair islet β cell function. Therefore, we hypothesized that iNOS gene silencing could …

From Isolated Tumour Cells To Overt Lymph Node Metastases: Biological And Imaging Studies On The Development Of Experimental Lymph Node Metastases, Michael M. Lizardo

Electronic Thesis and Dissertation Repository

Metastatic colonization and establishment of overt lymph node (LN) tumours indicates poor prognosis for cancer patients. However, the basic biology that influences the development of LN metastasis is poorly understood due to the lack of basic animal models. The following work provides a new lymph node experimental metastasis assay (LEMA) that permits the assessment of tumour cell fate after they arrest in draining LNs. In using this new model, we discovered that only 8% of the tumour cells that arrive in the LN are successful in forming overt tumours. This work also explored the use of imaging approaches to monitor …

Aims

Fatigue is a common occurrence in cancer patients regardless of tumor type or anti-tumor therapies and is an especially problematic symptom in persons with incurable tumor disease. In rodents, tumor-induced fatigue is associated with a progressive loss of skeletal muscle mass and increased expression of biomarkers of muscle protein degradation. The purpose of the present study was to determine if muscle wasting and expression of biomarkers of muscle protein degradation occur in the hearts of tumor-bearing mice, and if these effects of tumor growth are associated with changes in cardiac function.

Therapeutic Touch And Cancer Cells, Gloria A. Gronowicz

UCHC Graduate School Masters Theses 2003 - 2010

Energy medicine therapies based on a human biofield have been practiced for thousands of years and can trace their origin in Ayurveda. Our goal was to determine if Therapeutic Touch (TT), a more recently developed energy medicine practice, had any effects on cancer cells. Previous work in our laboratory demonstrated that TT significantly increased the growth of normal human osteoblasts and increased the synthesis of bone matrix proteins and mineralization in cell culture. In this study as was practiced in our previous studies, TT was performed twice a week for 10 minutes and was compared to untreated cultures and 'placebo-treated" …

The Impact Of Folate Deficiency On The Base Excision Repair Pathway: Analysis Of Enzyme Coordination In Response To Dna Damage And Imbalanced Repair, Amanda Pilling

Wayne State University Dissertations

The condition of folate deficiency has been implicated in carcinogenesis, with the strongest evidence formulated in colon cancer. The role of folate in DNA repair, DNA synthesis and methylation reactions renders this nutrient an valuable target for studying the onset and progression of cancer. Using molecular techniques to determine gene and protein expression, enzyme activity and methylation status elucidates the mechanism of DNA repair and damage in folic acid deficient animals in response to carcinogen. The findings presented in this study indicate failure to remove and repair damage in the condition of folate deficiency and suggest that the accumulation of …

Hedgehog Signaling: A Potential Therapeutic Target For Non-Small Cell Lung Cancer, Ma'in Yehya Maitah

Wayne State University Dissertations

The American Cancer Society estimated that 222,520 Americans were diagnosed with lung cancer and 157,300 died of lung cancer in 2010 (Jemal et al. 2009, 225-249;Jemal et al. 2011, 69-90). The clinical outcome of patients diagnosed with non-small cell lung cancer (NSCLC), the major lung cancer sub-types, is very poor, which calls for innovative research for finding novel therapeutic targets and agents for better treatment outcome.

Emerging evidences have suggested that a phenomenon called Epithelial-to-Mesenchymal Transition (EMT), which shares similar molecular characteristics with cancer stem-like cells, contributes to lung cancer treatment failure. In view of the fact that EMT process …

Complex Alternative Splicing Of The Smarca2 Gene Suggests The Importance Of Smarca2-B Variants., Min Yang, Yuan Sun, Ling Ma, Chenguang Wang, Jian-Min Wu, Anding Bi, D Joshua Liao

Department of Stem Cell Biology and Regenerative Medicine Faculty Papers & Presentations

BRM is an ATPase component of the SWI/SNF complex that regulates chromatin remodeling and cell proliferation and is considered a tumor suppressor. In this study we characterized transcripts from the Smarca2 gene that encodes the BRM protein. We found that the human Smarca2 gene (hSmarca2), like its mouse counterpart (mSmarca2), also initiated a short transcript from intron 27 of the long transcript. We name the long and short transcripts as Smarca2-a and Smarca2-b, respectively. Like its human counterpart, mSmarca2-a also underwent alternative splicing at the 54-bp exon 29. The hSmarca2-b had two alternative initiation sites and underwent alternative splicing at …

Altered Leptin Signaling On Dendritic Cells As A Potential Mechanism For Cancer Immunotherapy, Lorena Y. De Los Santos

Open Access Theses & Dissertations

Leptin is a pleiotropic hormone synthesized primarily by white adipocytes and its receptors are expressed in a variety of tissues and cells such as in the hypothalamus and cells of the immune system. Multiple cell types can produce a considerable amount of leptin such as skeletal muscle, placenta, and osteoblasts to name a few and its synthesis has been shown to be regulated by sex hormones and a broad range of inflammatory mediators. Although leptin has been shown to directly affect immune response, we are interested in how leptin affects dendritic cell function and their ability to induce a proper …

Stem Cell Biology And Strategies For Therapeutic Development In Degenerative Diseases And Cancer, Angel A. Alvarez

Electronic Theses and Dissertations

Stem cell biology is an exciting field that will lead to significant advancements in science and medicine. We hypothesize that inducing the expression of stem cell genes, using the embryonic stem cell gene nanog, will reprogram cells and dedifferentiate human mesenchymal stem cells into pluripotent stem cells capable of neural differentiation. The aims of initial studies are as follows: Aim 1: Demonstrate that forced expression of the embryonic stem cell gene nanog induces changes in human mesenchymal stem cells to an embryonic stem cell-like phenotype. Aim 2: Demonstrate that induced expression of nanog up-regulates the expression of multiple embryonic stem …
