The spread of metastatic tumors to different organs is associated with poor prognosis. The metastatic process requires migration and cellular invasion. The protooncogene c-jun encodes the founding member of the activator protein-1 family and is required for cellular proliferation and DNA synthesis in response to oncogenic signals and plays an essential role in chemical carcinogenesis. The role of c-Jun in cellular invasion remains to be defined. Genetic deletion of c-Jun in transgenic mice is embryonic lethal; therefore, transgenic mice encoding a c-Jun gene flanked by LoxP sites (c-jun(f/f)) were used. c-jun gene deletion reduced c-Src expression, hyperactivated ROCK II signaling, …

Inhibition Of Oncogene-Induced Inflammatory Chemokines Using A Farnesyltransferase Inhibitor., Katharine C Degeorge, Brent R Degeorge, James S Testa, Jay L Rothstein

Kimmel Cancer Center Faculty Papers

BACKGROUND: Farnesyltransferase inhibitors (FTI) are small molecule agents originally formulated to inhibit the oncogenic functions of Ras. Although subsequent analysis of FTI activity revealed wider effects on other pathways, the drug has been demonstrated to reduce Ras signaling by direct measurements. The purpose of the current study was to determine if FTI could be used to inhibit the inflammatory activities of a known Ras-activating human oncoprotein, RET/PTC3. RET/PTC3 is a fusion oncoprotein expressed in the thyroid epithelium of patients afflicted with thyroid autoimmune disease and/or differentiated thyroid carcinoma. Previous studies have demonstrated that RET/PTC3 signals through Ras and can provoke …

Retinoic Acid Decreases Atf-2 Phosphorylation And Sensitizes Melanoma Cells To Taxol-Mediated Growth Inhibition, Ying Huang, Jennifer Minigh, Sarah Miles, Richard N. Niles

Biochemistry and Microbiology

Cutaneous melanoma is often resistant to chemo- and radiotherapy. This resistance has recently been demonstrated to be due, at least in part, to high activating transcription factor 2 (ATF-2) activity in these tumors. In concordance with these reports, we found that B16 mouse melanoma cells had higher levels of ATF-2 than immortalized, but non-malignant mouse melanocytes. In addition, the melanoma cells had a much higher amount of phosphorylated (active) ATF-2 than the immortalized melanocytes. In the course of determining how retinoic acid (RA) stimulates activating protein-1 (AP-1) activity in B16 melanoma, we discovered that this retinoid decreased the phosphorylation of …

Celecoxib Concentration Predicts Decrease In Prostaglandin E2 Concentrations In Nipple Aspirate Fluid From High Risk Women, Edward R. Sauter, Wenyi Qin, John E. Hewett, Rachel L. Ruhlen, John T. Flynn, George Rottinghaus, Yin-Chieh Chen

Department of Molecular Physiology and Biophysics Faculty Papers

BACKGROUND: Epidemiologic studies suggest that long term low dose celecoxib use significantly lowers breast cancer risk. We previously demonstrated that 400 mg celecoxib taken twice daily for 2 weeks lowered circulating plasma and breast nipple aspirate fluid (NAF) prostaglandin (PG)E2 concentrations in post- but not premenopausal high risk women. We hypothesized that circulating concentrations of celecoxib influenced PGE2 response, and that plasma levels of the drug are influenced by menopausal status. To address these hypotheses, the aims of the study were to determine: 1) if circulating plasma concentrations of celecoxib correlated with the change in plasma or NAF PGE2 concentrations …

Nitrated Alpha-Synuclein Immunity Accelerates Degeneration Of Nigral Dopaminergic Neurons., Eric J. Benner, Rebecca Banerjee, Ashley D. Reynolds, Simon Sherman, Vladimir M. Pisarev, Vladislav Tsiperson, Craig Nemachek, Pawel Ciborowski, Serge Przedborski, R. Lee Mosley, Howard Gendelman

Journal Articles: Eppley Institute

BACKGROUND: The neuropathology of Parkinson's disease (PD) includes loss of dopaminergic neurons in the substantia nigra, nitrated alpha-synuclein (N-alpha-Syn) enriched intraneuronal inclusions or Lewy bodies and neuroinflammation. While the contribution of innate microglial inflammatory activities to disease are known, evidence for how adaptive immune mechanisms may affect the course of PD remains obscure. We reasoned that PD-associated oxidative protein modifications create novel antigenic epitopes capable of peripheral adaptive T cell responses that could affect nigrostriatal degeneration.

METHODS AND FINDINGS: Nitrotyrosine (NT)-modified alpha-Syn was detected readily in cervical lymph nodes (CLN) from 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) intoxicated mice. Antigen-presenting cells within the CLN …

Role Of Transient Receptor Potential Canonical-6 (Trpc6) Channel In Metastasis Of Glioblastoma Multiforme, Rajarajeshwari Venkataraman

Electronic Theses and Dissertations

Glioblastoma multiforme (GBM) is one of the extremely fatal brain tumors. The main reason that makes it so lethal is its capability to invade and spread to other parts of CNS producing secondary tumors. Among other factors hypoxia, reduced oxygen availability, is linked to higher metastatic potential of cancers. Hypoxia causes numerous changes in genome and proteome of the cell. These changes help a normal cell to adapt to nutritional deficiency, but the same changes can increase the malignancy and metastasis in tumor cells. Extensive research by a number of curious scientists reveal that various pathways involving numerous proteins cross-talk …

The Function And Mechanism Of Chmp1a In Tumor Development, Jing Li

Theses, Dissertations and Capstones

Chmp1A (Chromatin modifying protein 1A/Charged multivesicular protein 1A) is a member of the ESCRT-III (Endosomal Sorting Complex Required for Transport) family, which mediates trafficking via MVB (multivesicular body) formation and sorting. Our studies suggest that Chmp1A is a novel tumor suppressor, especially in the pancreas. Knockdown of Chmp1A resulted in an increase of anchorage-independent growth of HEK 293T cells. Moreover, we showed that Chmp1A depleted HEK 293T cells forms tumor in xenograft mice. Knockdown of Chmp1A in PanC-1 cells promoted cell growth. In contrast, Doxycycline induced over-expression of Chmp1A in pancreatic cancer cells (PanC-1) resulted in cell growth inhibition, tumor …

The Psychosocial Effects Of Pediatric Cancer On Young Adult Cancer Survivors, Jacob D. Schaefer

Graduate Research Papers

Childhood cancer is a current problem in our society. Today survivor rates are increasing. There are increased numbers of childhood survivors dealing with the after affects of cancer as they move into adulthood. Research correlations between childhood problems and adulthood problems have emerged. Issues of psychological, social, and physical concerns have created difficulties for childhood cancer survivors. However, there have been mixed results as some researches show healthy adaptation while others indicate abnormal daily functioning of children and young adults. Future research areas should focus on individual coping methods, social function of young adult survivors, and the human developmental process …

Preclinical Studies Of Apogossypolone: A New Nonpeptidic Pan Small-Molecule Inhibitor Of Bcl-2, Bcl-XL And Mcl-1 Proteins In Follicular Small Cleaved Cell Lymphoma Model, Alan A. Arnold, Amro Aboukameel, Jianyong Chen, Dajun Yang, Shaomeng Wang, Ayad Al-Katib, Ramzi M. Mohammad

Wayne State University Associated BioMed Central Scholarship

Abstract

Elevated expression of anti-apoptotic Bcl-2 family proteins have been linked to a poor survival rate of patients with Follicular Lymphoma (FL). This prompted us to evaluate a very potent non-peptidic Small-Molecule Inhibitor (SMI) targeting Bcl-2 family proteins, Apogossypolone (ApoG2) using follicular small cleaved cell lymphoma cell line (WSU-FSCCL) and cell isolated from lymphoma patients. ApoG2 inhibited the growth of WSU-FSCCL significantly with a 50% growth inhibition of cells (IC₅₀) of 109 nM and decreased cell number of fresh lymphoma cells. ApoG2 activated caspases-9, -3, and -8, and the cleavage of Poly (ADP-ribose) polymerase (PARP) and Apoptosis Inducing …

Gene Expression Profiles In Primary Pancreatic Tumors And Metastatic Lesions Of Ela-C-Myc Transgenic Mice, Archana Thakur, Aliccia Bollig, Jiusheng Wu, Dezhong J. Liao

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Pancreatic carcinoma usually is a fatal disease with no cure, mainly due to its invasion and metastasis prior to diagnosis. We analyzed the gene expression profiles of paired primary pancreatic tumors and metastatic lesions from Ela-c-myc transgenic mice in order to identify genes that may be involved in the pancreatic cancer progression. Differentially expressed selected genes were verified by semi-quantitative and quantitative RT-PCR. To further evaluate the relevance of some of the selected differentially expressed genes, we investigated their expression pattern in human pancreatic cancer cell lines with high and low metastatic potentials.

Results

Data indicate that genes …

Hiv-1 Tat And Aids-Associated Cancer: Targeting The Cellular Anti-Cancer Barrier?, Giuseppe Nunnari, Johanna A Smith, René Daniel

Department of Medicine Faculty Papers

The acquired immunodeficiency syndrome (AIDS) is accompanied by a significant increase in the incidence of neoplasms. Several causative agents have been proposed for this phenomenon. These include immunodeficiency and oncogenic DNA viruses and the HIV-1 protein Tat. Cancer in general is closely linked to genomic instability and DNA repair mechanisms. The latter maintains genomic stability and serves as a cellular anti-cancer barrier. Defects in DNA repair pathway are associated with carcinogenesis. This review focuses on newly discovered connections of the HIV-1 protein Tat, as well as cellular co-factors of Tat, to double-strand break DNA repair. We propose that the Tat-induced …

Distinguishing Post-Treatment Changes From Recurrent Disease In Cholangiocarcinoma: A Case Report., Timothy N Showalter, A Omer Nawaz, Frederick M Fellin, Pramila R Anne, Ernest L Rosato, Adam P Dicker

Department of Radiation Oncology Faculty Papers

INTRODUCTION: Three-dimensional techniques for radiotherapy have expanded possibilities for partial volume liver radiotherapy. Characteristic, transient radiographic changes can occur in the absence of clinical radiation-induced liver disease after hepatic radiotherapy and must be distinguished from local recurrence. CASE PRESENTATION: In this report, we describe computed tomography changes after chemoradiotherapy for cholangiocarcinoma as an example of collaboration to determine the clinical significance of the radiographic finding. CONCLUSION: Because of improved three-dimensional, conformal radiotherapy techniques, consultation across disciplines may be necessary to interpret post-treatment imaging findings.

Sensitization Of Ovarian Cancer Cells To Cisplatin By Genistein: The Role Of Nf-Kappab, Leigh A. Solomon, Shadan Ali, Sanjeev Banerjee, Adnan R. Munkarah, Robert T. Morris, Fazlul H. Sarkar

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Platinum-resistance (PR) continues to be a major problem in the management of epithelial ovarian cancer (EOC). Response to various chemotherapeutic agents is poor in patients deemed PR. Genistein, a soy isoflavone has been shown to enhance the effect of chemotherapy in prostate and pancreatic cancer cells in vitro and in vivo by reversing chemo-resistance phenotype. The goal of this study was to investigate the effects of combination therapy with genistein and cisplatin as well as other cytotoxic conventional chemotherapeutic agents in platinum-sensitive (PS) and resistant EOC cells.

A Stable Explant Culture Of Her2/Neu Invasive Carcinoma Supported By Alpha-Smooth Muscle Actin Expressing Stromal Cells To Evaluate Therapeutic Agents, Marie P. Piechocki

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

To gain a better understanding of the effects of therapeutic agents on the tumor microenvironment in invasive cancers, we developed a co-culture model from an invasive lobular carcinoma. Tumor cells expressing HER2/neu organize in nests surrounded by alpha-Smooth Muscle Actin (α-SMA) expressing tumor stroma to resemble the morphology of an invading tumor. This co-culture, Mammary Adenocarcinoma Model (MAM-1) maintains a 1:1 ratio of HER2/neu positive tumor cells to α-SMA-reactive stromal cells and renews this configuration for over 20 passages in vitro.

Methods

We characterized the cellular elements of the MAM-1 model by microarray analysis, and immunocytochemistry. We developed …
