Adaptive Radiation Therapy Of Prostate Cancer, Ning Wen

Wayne State University Dissertations

ART is a close-loop feedback algorithm which evaluates the organ deformation and motion right before the treatment and takes into account dose delivery variation daily to compensate for the difference between planned and delivered dose. It also has potential to allow further dose escalation and margin reduction to improve the clinical outcome. This retrospective study evaluated ART for prostate cancer treatment and radiobiological consequences. An IRB approved protocol has been used to evaluate actual dose delivery of patients with prostate cancer undergoing treatment with daily CBCT.

The dose from CBCT was measured in phantom using TLD and ion chamber techniques …

Identification Of Neuroblastoma And Its Prognostic Markers Using Raman Spectroscopy, Rachel Kast

Wayne State University Dissertations

Introduction: Neuroblastoma is the most common cancer of infancy. It is one of several peripheral nervous system tumors, including ganglioneuroma, peripheral nerve sheath tumor, and pheochromocytoma. It is commonly situated on the adrenal gland. It displays similar histology to other small round blue cell tumors, including non-Hodgkin lymphoma, rhabdomyosarcoma, and Ewing sarcoma. One method of judging neuroblastoma aggressiveness uses tumor histology factors, including mitosis-karyorrhexis index, Schwannian stromal development, degree of differentiation, and patient age. Tumor aggressiveness can also be judged based on the amplification of certain genes, including MYCN. Raman spectroscopy is a physics-based method which identifies the biochemical …

Egfr/Met Association Regulates Egfr Tki Resistance In Breast Cancer, Kelly L. Mueller, Zeng-Quan Yang, Ramsi Haddad, Stephen P. Ethier, Julie L. Boerner

Wayne State University Associated BioMed Central Scholarship

Abstract

Breast cancers show a lack of response to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs), despite 30% of tumors expressing EGFR. The mechanism of this resistance is unknown; however, we have recently shown that Met kinase activity compensates for loss of EGFR kinase activity in cell culture models. Met has been implicated in the pathogenesis of breast tumors and therefore may cooperate with EGFR for tumor growth. Here we have found that EGFR phosphorylation and cell proliferation is in part regulated by Met expression. In addition, we found that Met constitutive phosphorylation occurred independent of the Met …

Mechanism Of Catch Force: Tethering Of Thick And Thin Filaments By Twitchin., Thomas M Butler, Marion J Siegman

Department of Molecular Physiology and Biophysics Faculty Papers

Catch is a mechanical state occurring in some invertebrate smooth muscles characterized by high force maintenance and resistance to stretch during extremely slow relaxation. During catch, intracellular calcium is near basal concentration and myosin crossbridge cyctng rate is extremely slow. Catch force is relaxed by a protein kinase A-mediated phosphorylation of sites near the N- and C- temini of the minititin twitchin (approximately 526 kDa). Some catch force maintenance car also occur together with cycling myosin crossbridges at submaximal calcium concentrations, but not when the muscle is maximally activated. Additionally, the link responsible for catch can adjust during shortening of …

Differential Impact Of Tumor Suppressor Pathways On Dna Damage Response And Therapy-Induced Transformation In A Mouse Primary Cell Model., A Kathleen Mcclendon, Jeffry L Dean, Adam Ertel, Erik S Knudsen

Department of Cancer Biology Faculty Papers

The RB and p53 tumor suppressors are mediators of DNA damage response, and compound inactivation of RB and p53 is a common occurrence in human cancers. Surprisingly, their cooperation in DNA damage signaling in relation to tumorigenesis and therapeutic response remains enigmatic. In the context of individuals with heritable retinoblastoma, there is a predilection for secondary tumor development, which has been associated with the use of radiation-therapy to treat the primary tumor. Furthermore, while germline mutations of the p53 gene are critical drivers for cancer predisposition syndromes, it is postulated that extrinsic stresses play a major role in promoting varying …

Human Pancreatic Cancer (PaCa) is one of the most hostile and fourth leading cause of cancer deaths in the United States. Current standard chemotherapeutic agent for advanced PaCa is gemcitabine, a cytotoxic nucleoside analogue which results in modest response due to high degree of inherent and acquired chemo resistance. Forthcoming evidence strongly supports that non-nutritive food components have therapeutic benefits attributable to pleiotropic …

Chemosensitization Of Cancer Cells By Sirna Using Targeted Nanogel Delivery, Erin B. Dickerson, William H. Blackburn, Michael H. Smith, Laura B. Kapa, L. Andrew Lyon, John F. Mcdonald

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Background: Chemoresistance is a major obstacle in cancer treatment. Targeted therapies that enhance cancer cell sensitivity to chemotherapeutic agents have the potential to increase drug efficacy while reducing toxic effects on untargeted cells. Targeted cancer therapy by RNA interference (RNAi) is a relatively new approach that can be used to reversibly silence genes in vivo by selectively targeting genes such as the epidermal growth factor receptor (EGFR), which has been shown to increase the sensitivity of cancer cells to taxane chemotherapy. However, delivery represents the main hurdle for the broad development of RNAi therapeutics.

Methods: We report here …

Plasmid Injection And Application Of Electric Pulses Alter Endogenous Mrna And Protein Expression In B16.F10 Mouse Melanomas, L. C. Heller, Y. L. Cruz, B. Ferraro, H. Yang, R. Heller

Bioelectrics Publications

The application of electric pulses to tissues causes cell membrane destabilization, allowing exogenous molecules to enter the cells. This delivery technique can be used for plasmid gene therapy. Reporter gene expression after plasmid delivery with eight representative published protocols was compared in B16.F10 mouse melanoma tumors. This expression varied significantly based on the pulse parameters utilized for delivery. To observe the possible influence of plasmid injection and/or pulse application on endogenous gene expression, levels of stress-related mRNAs 4 and 24 h after delivery were determined by PCR array. Increases in mRNA levels for several inflammatory chemokines and cytokines were observed …

Apoptosis Initiation And Angiogenesis Inhibition: Melanoma Targets For Nanosecond Pulsed Electric Fields, Xinhua Chen, Juergen F. Kolb, R. James Swanson, Karl H. Schoenbach, Stephen J. Beebe

Bioelectrics Publications

Many effective anti-cancer strategies target apoptosis and angiogenesis mechanisms. Applications of non-ionizing, nanosecond pulsed electric fields (nsPEFs) induce apoptosis in vitro and eliminate cancer in vivo; however in vivo mechanisms require closer analysis. These studies investigate nsPEF-induced apoptosis and anti-angiogenesis examined by fluorescent microscopy, immunoblots, and morphology. Six hours after treatment with one hundred 300 ns pulses at 40 kV/cm, cells transiently expressed active caspases indicating that caspase-mediated mechanisms. Three hours after treatment transient peaks in Histone 2AX phosphorylation coincided with terminal deoxynucleotidyl transferase dUTP nick end labeling positive cells and pyknotic nuclei, suggesting caspase-independent mechanisms on nuclei/DNA. Large …

The Wnt/Β-Catenin Pathway Regulates Growth And Maintenance Of Colonospheres, Shailender S. Kanwar, Yingjie Yu, Jyoti Nautiyal, Bhaumik B. Patel, Adhip Pn Majumdar

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Recent evidence suggests that epithelial cancers, including colorectal cancer are driven by a small sub-population of self-renewing, multi-potent cells termed cancer stem cells (CSCs) which are thought to be responsible for recurrence of cancer. One of the characteristics of CSCs is their ability to form floating spheroids under anchorage-independent conditions in a serum-free defined media. The current investigation was undertaken to examine the role of Wnt/β-catenin pathway in regulating the growth and maintenance of colonospheres. Human colon cancer cells HCT-116 (p53 wild type; K-ras mutant), HCT-116 (p53 null; K-ras mutant) and HT-29 (p53 mutant) were used.

A Novel Mechanism Of Cell Growth Regulation By Cell Cycle And Apoptosis Regulatory Protein (Carp)-1, Yan Jiang, Vineshkumar T. Puliyappadamba, Liyue Zhang, Wenjuan Wu, Anil Wali, Michael B. Yaffe, Joseph A. Fontana, Arun K. Rishi

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

CARP-1/CCAR1, a perinuclear phospho-protein, regulates signaling by adriamycin, steroids, or growth factors. However, intracellular events that regulate CARP-1-dependent cell growth are not fully understood.

Results

Here we investigated whether CARP-1 is involved in signaling induced by the protein kinase A inhibitor H89. Treatments of human breast cancer cells with H89 resulted in apoptosis that involved enhanced CARP-1 threonine phosphorylation and expression. Depletion of CARP-1, on the other hand, abrogates apoptosis induced by H89. CARP-1 binds with signal transducer TAZ and over-expression of TAZ inhibits apoptosis by CARP-1. CARP-1 (651-759) interacts with a novel, N-terminal epitope of TAZ. H89 …

Marine Algae As A Source Of Photosensitisers For Photodynamic Therapy Of Cancer., Tang Yee Voon

Student Works (2010-2019)

Photodynamic therapy (PDT) involves the intravenous administration of a photosensitiser that preferentially localises in cancerous tissues more than the surrounding normal tissues. Subsequent illumination of photosensitiser generates reactive oxygen species that cause irreversible photo-damage to the cancer cells. To date, most photosensitisers that have been approved for clinical use or are currently in clinical trials are cyclic tetrapyrroles which are derived or inspired by naturally occurring chlorophyll and its degradation products. Some non-tetrapyrrolic photosensitisers have also been found in nature suggesting that there are potential photosensitisers with interesting structures in nature. To this end, this thesis outlines the collection of …

Student Works (2010-2019)

Introduction Oral cancer is a significant health problem worldwide with almost 300,000 new cases are diagnosed each year. Despite the numerous studies done, and even with the best treatment option utilized, more than 50% of patients with oral cancer will experience relapse. In search for better options for prognostication, researches are now focusing on the molecular biology of cancer, for instance in search of reliable tumor markers. Among the markers reported in the literatures, Cyclin D1 is actively studied protein. Cyclin D1 regulates the cell cycle progression by forming a complex with different cyclin dependant kinase. Dysregulation of cyclin D1 …

Quantification Of Circulating Melanoma Cells, Jamie Freeman

Theses : Honours

Current prognostic techniques for Cutaneous Malignant Melanoma (CMM), a highly aggressive and drug resistant skin cancer, are inadequate at managing the disease and identifying early stage patients requiring treatment. It is thought that Circulating Tumour Cells (CTCs), which circulate in patient blood after being shed from solid tumours, may be useful in enhancing prognostic techniques and it has previously been shown in other malignancies that the presence of CTCs in patient blood is associated with poor prognosis. In CMM, CTCs can be detected through RT-PCR for melanoma associated markers, although this technique does not allow CTCs to be quantified. In …

Differential Genome-Wide Array–Based Methylation Profiles In Prognostic Subsets Of Chronic Lymphocytic Leukemia, Meena Kanduri, Nicola Cahill, Hanna Göransson, Camilla Enström, Fergus Ryan, Anders Isaksson, Richard Rosenquist

Articles

Global hypomethylation and regional hypermethylation are well-known epigenetic features of cancer; however, in chronic lymphocytic leukemia (CLL), studies on genome-wide epigenetic modifications are limited. Here, we analyzed the global methylation profiles in CLL, by applying high-resolution methylation microarrays (27 578 CpG sites) to 23 CLL samples, belonging to the immunoglobulin heavy-chain variable (IGHV) mutated (favorable) and IGHV unmutated/IGHV3-21 (poor-prognostic) subsets. Overall, results demonstrated significant differences in methylation patterns between these subgroups. Specifically, in IGHV unmutated CLL, we identified methylation of 7 known or candidate tumor suppressor genes (eg, VHL, ABI3, and IGSF4) as well as 8 unmethylated genes involved in …

The NCCN guidelines do not recommend FDG-PET as a part of standard workup. The purpose of this report is to examine the role of FDG-PET imaging in altering management and providing prognostic information for HNC.

METHODS: Retrospective review of HNC patients who had a staging FDG-PET scan performed at either Thomas Jefferson University or University of Kansas Medical Center between the years 2001 and 2007. A total of 212 PET scans were performed in patients who went on …

Notch-1 Activates Nf-Кb Activity In Cervical Cancer And Estrogen Receptor Negative Breast Cancer, Yin Peng

Dissertations

Breast and cervical cancer are two common cancers that severely endanger women's health. The fatality rates of breast and cervical cancer are ranked first and fifth, respectively, in cancer related deaths in women worldwide. Continuous dedication to cancer research is urgently required to elucidate the cancer cell survival mechanism that is responsible for disease aggressiveness and poor prognosis.

Emerging data indicate that Notch-1 is aberrantly regulated in human cervical and ER- breast cancer and inhibiting Notch-1 sensitizes cancer cells to apoptosis. However, the mechanism by which Notch-1 promotes cell survival is not known. NF-КB is also deregulated in these two …

Novel Cis-Trans Interactions Are Involved In Post-Transcriptional Regulation Of Cyclin-Dependent Kinase Inhibitor P21Waf1/Cip1 Mrna, Liyue Zhang, Anil Wali, Joseph A. Fontana, Marcia I. Dawson, Arun K. Rishi

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

A variety of pathways target CDKI p21^WAF1/CIP1 expression at transcriptional, post-transcriptional as well as translational levels. We previously found that cell growth suppressing retinoid CD437 enhanced expression of p21^WAF1/CIP1 and DNA damage inducible GADD45 proteins in part by elevating their mRNA stability.

Results

Here, we investigated molecular mechanisms of CD437-dependent post-transcriptional regulation of p21^WAF1/CIP1 expression. By utilizing MDA-MB-468 HBC cells expressing chimeric rabbit β-globin-p21^WAF1/CIP1 transcripts we mapped multiple CD437-responsive sequences located within positions 1195 to 1795 of the 3'-untranslated region of p21^WAF1/CIP1 mRNA. Several cytoplasmic proteins present in MDA-MB-468, MCF-7 HBC as well …
