Precise Method To Identify Kinase Drug Targets In Complex Diseases: The First Step Towards Sustainable And Effective Treatment, Hasbanny Irisson, Marzieh Ayati
Precise Method To Identify Kinase Drug Targets In Complex Diseases: The First Step Towards Sustainable And Effective Treatment, Hasbanny Irisson, Marzieh Ayati
Research Symposium
Background: Kinases are enzymes that have proven to be important drug targets due to their role in critical biological mechanisms such as phosphorylation. Phosphorylation happens when a kinase catalyzes the transfer of a phosphate group to a protein in a phosphorylated site, which then becomes known as the substrate of the kinase. Any dysregulation of protein phosphorylation causes a wide range of complex diseases including cancer. Thus, discovering the links between kinases and their substrates (i.e. predicting kinase-substrate associations (KSAs)) is crucial in developing effective and sustainable treatments. Presently, less than 5% of phosphorylated sites have an associated kinase, and …

Mortaparibplus- A Novel Anticancer Small Molecule Abrogating Mortalin-P53 Interaction In Cancer Cells, Anissa N. Sari, Ahmed Elwakeel, Jaspreet K. Dhanjal, Vipul Kumar, Durai Sundar, Sunil C. Kaul, Renu Wadhwa
Research Symposium
Background. The cessation of tumor cell growth through cell cycle arrest and apoptosis is determined by p53, a tumor suppressor protein. However, the interaction between mortalin-p53 within cytoplasm/nucleus leads to the inactivation of p53 transcriptional activation function. The disruption of mortalin-p53 complex has been suggested as an approach for developing a potential anticancer drug.
Methods. A screening of a high-content chemical library was performed to determine a molecule with mortalin-p53-interaction disrupting characteristics. After four-rounds of visual assays, we discovered a triazole derivative (4-[(1E)-2-(2-phenylindol-3-yl)-1-azavinyl]-1,2,4-triazole, named MortaparibPlus) with a potential ability of disrupting mortalin-p53-complex. In this study, we recruited …

Nanoparticle Conjugated Photosensitizer For Targeted Photodynamic Inactivation Of Cancer Cells, Symone D. Crowder
Honors College Theses
Photodynamic therapy (PDT) is considered to be a potential replacement for traditional methods of chemotherapy. It includes the administration of photosensitizing agents (PS), which generate reactive oxygen species (ROS) upon excitation at a specific wavelength. With new outlooks and techniques, cancer research is advancing each day. It has allowed the progress of several theranostic drug delivery systems (DDS) exploring the area of nanomedicine.2 In the present work, a Rhodamine derivative, Rhodamine 6G (R6G) was used as the PS. In general, rhodamine compounds undergo cytotoxic reactions on photoexcitation by electron transfer reactions with folic acid within cells, making them a favorable …

Natural products have long been used as candidates for therapy in the management of cancer. Violacein, a bacterial pigment, has been known for its numerous biological applications such as antimicrobial, antileishmanial, antiviral, as well as antitumoral. Computational studies have concluded that it may have activity against cancers like pancreatic cancer, thyroid cancer, colorectal cancer, and endometrial cancer indicating its potential application as a broad range of anti-cancerous drug. This study aimed to perform the molecular docking of violacein with …
The Role Of Foxd1 In Clear Cell Renal Cell Carcinoma, Kyle H. Bond
The Role Of Foxd1 In Clear Cell Renal Cell Carcinoma, Kyle H. Bond
Electronic Theses and Dissertations
Renal cell carcinoma (RCC) is the 8th most common cancer in the United States, with the clear cell variant (ccRCC) being the most prevalent. Over 14,000 people die every year to RCC, with rates continuing to increase with an aging general population. Patients suffering from metastatic RCC (mRCC) have extremely poor prognoses, with a 5-year survival of only 11.2%. Current treatment options include resection of primary lesions, tyrosine kinase inhibition (Sunitinib, Pazopanib), mTOR inhibition (Temsirolimus, Everolimus), and immune checkpoint inhibition (Nivolumab, Atezolizumab). Recent attention has been drawn to inhibition of transcription factors like HIF2α (Belzutifan). There is a need …
Unraveling Host-Gut Microbiota Dialogue And Its Impact On Response To Immune Checkpoint Blockade, Alexandria Cogdill
Unraveling Host-Gut Microbiota Dialogue And Its Impact On Response To Immune Checkpoint Blockade, Alexandria Cogdill
Dissertations & Theses (Open Access)
Cancer is a disease with only one degree of separation, affecting one in two men and one in three women in their lifetimes; accounting for 1 of every 6 deaths. While cancer mortality rates continue to improve, incidence rates are expected to rise and shift through 2050 due to epidemiological and demographic transitions worldwide. As such, it is imperative to continue to investigate and improve our understanding of both disease etiology and hallmarks of response to treatment. Currently, conventional therapies include, but are not limited to, surgery, chemotherapy, and radiotherapy. However, within the past decade, major advances have been made …
Position-Scanning Peptide Libraries As Particle Immunogens For Improving Cd8+ T-Cell Responses, Michael C. Vega
Position-Scanning Peptide Libraries As Particle Immunogens For Improving Cd8+ T-Cell Responses, Michael C. Vega
Faculty Peer-Reviewed Publications
Short peptides reflecting major histocompatibility complex (MHC) class I (MHC-I) epitopes frequently lack sufficient immunogenicity to induce robust antigen (Ag)-specific CD8+ T cell responses. In the current work, it is demonstrated that position-scanning peptide libraries themselves can serve as improved immunogens, inducing Ag-specific CD8+ T cells with greater frequency and function than the wild-type epitope. The approach involves displaying the entire position-scanning library onto immunogenic nanoliposomes. Each library contains the MHC-I epitope with a single randomized position. When a recently identified MHC-I epitope in the glycoprotein gp70 envelope protein of murine leukemia virus (MuLV) is assessed, only one …

Proper timely management of various external and internal stresses is critical for metabolic and redox homeostasis in mammals. In particular, dysregulation of mechanistic target of rapamycin complex (mTORC) triggered from metabolic stress and accumulation of reactive oxygen species (ROS) generated from environmental and genotoxic stress are well-known culprits leading to chronic metabolic disease conditions in humans. Sestrins are one of the metabolic and environmental stress-responsive groups of proteins, which solely have the ability to regulate both mTORC activity and ROS levels in cells, tissues and organs. While Sestrins are originally reported as one of several p53 target genes, recent studies …

Practical Applications And Future Directions Of Genetic Code Expansion: Validation Of Novel Akt1 Substrates And The Design Of A Synthetic Auxotroph Strain Of B. Subtilis, Mcshane M. Mckenna
Electronic Thesis and Dissertation Repository
In Chapter 1, site-specifically phosphorylated variants of the oncogene Akt1 were made in Escherichia coli using the orthogonal translation system that enable genetic code expansion with phosphoserine. The differentially phosphorylated variants of Akt1 were used to validate newly predicted Akt1 substrates. The predicted target sites of the peptide substrates were synthesized and subjected to in vitro kinase assays to quantify the activity of each Akt1 phosphorylated variant towards the predicted peptide. A previously uncharacterized kinase-substrate interaction between Akt1 and a peptide derived from RAB11 Family Interacting Protein 2 (RAB11FIP2) was validated in vitro. Chapter 2 describes the preliminary development of …

Applications Of Phosphotyrosine Superbinding Sh2 Domain Variants, Xuguang Liu
Applications Of Phosphotyrosine Superbinding Sh2 Domain Variants, Xuguang Liu
Electronic Thesis and Dissertation Repository
Protein tyrosine kinases (PTKs, or TKs) have emerged as one of the most intensively pursued targets in the development of anti-cancer therapeutics, due to their critical roles in the phosphotyrosine (pTyr)-mediated signaling network that regulates many cancer-related cellular activities. The TKs, tyrosine phosphorylation phosphatases (PTPs) and pTyr recognition SH2 proteins are intensively tyrosine phosphorylated, which play a pivotal role in determining the signaling outcome of this network. More than 50% of all human proteins are tyrosine phosphorylated and many of these TK substrates have been proven functional in TK regulated cellular activities. Therefore, proteomics studies of tyrosine phosphorylation are of …

The normal mammary microenvironment can suppress tumorigenesis and redirect cancer cells to adopt a normal mammary epithelial cell fate in vivo. Understanding of this phenomenon offers great promise for novel treatment and detection strategies in cancer, but current model systems make mechanistic insights into the process difficult. We have recently described a low-cost bioprinting platform designed to be accessible for basic cell biology laboratories. Here we report the use of this system for the study of tumorigenesis and microenvironmental redirection of breast cancer cells. We show our bioprinter significantly increases tumoroid formation in 3D collagen gels and allows for precise …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Benzene, a toxin and carcinogen found in air polluted by cigarette smoke, car exhaust, and industrial processes, is associated with the development of leukemia and lymphoma. Other than avoiding exposure, there is no current method to deter the effects of benzene. One potential strategy to prevent these effects is to engineer the bacteria of the human lung microbiome to degrade benzene. To evaluate this novel approach, we must verify that the bacteria remain viable within the lung microenvironment. To do so, lungs were harvested from rats and swabbed to determine the contents of the original lung microbiome. Then green fluorescent …

B7h6: A Cancer Biomarker For The Development Of Novel Immunotherapy Approaches, Mariana Phillips
Seton Hall University Dissertations and Theses (ETDs)
Cancer-based immunotherapy has led the evolution of biologics that can stimulate immune responses towards tumor eradication. The synthesis of small to intermediate size molecules with the targeting and effector functions of mAb may represent a novel class of immunotherapeutics that may overcome the limitations of their biological counterparts.Towards this objective, B7H6 has been identified as a protein ligand localized on the cell surface of transformed tumor cells. B7H6 binds specifically to the activating receptor NKp30, constitutively expressed on all resting and active NK cells. Upon ligand:receptor binding, B7H6 triggers NK cell activation and release of chemokines and pro-inflammatory cytokines such …

Investigating The Essential Roles Of Dprl-1 In Drosophila Melanogaster, Alex Lee
Summer Research
Phosphatase of Regenerating Liver (PRL) proteins regulate a number of important cellular processes, including cell growth and division. Humans have three PRL proteins: PRL-1, PRL-2, and PRL-3. An accumulation of evidence has shown that elevated levels of PRLs are strongly correlated with uncontrollable growth and metastasis of tumors. However, contradictory findings have arisen indicating that PRLs instead function to halt cell division thereby preventing uncontrollable tumor growth. In light of these results, the underlying mechanisms regarding how PRLs function within cellular processes remains unclear. To investigate the functions of PRLs, we will create transgenic fruit flies (Drosophila melanogaster) …

Screening Of Synthetic Chemical Agents “Chromenes” With Potent Anti-Breast Cancer Activity, Aysha Hamad Zaher Saeed Al Meqbali
Theses
Cancer is the second leading cause of death worldwide. Conventional therapies cause serious side effects and, at best, merely extend the patient’s lifespan by a few years. Cancer control may therefore benefit from the potential that resides in alternative therapies. There is thus an increasing demand to utilize alternative concepts or approaches to the prevention of cancer. The principal aim of this research is to screen and identify new synthetic compounds “chromenes”, with high efficiency, for breast cancer therapy. In this study, we have screened four newly designed and synthesized chromenes (C1, C15, C28 and C29) for their potential anticancer …

Dysregulation in signal transduction pathways can lead to a variety of complex disorders, including cancer. Computational approaches such as network analysis are important tools to understand system dynamics as well as to identify critical components that could be further explored as therapeutic targets. Here, we performed perturbation analysis of a large-scale signal transduction model in extracellular environments that stimulate cell death, growth, motility, and quiescence. Each of the model's components was perturbed under both loss-of-function and gain-of-function mutations. Using 1,300 simulations under both types of perturbations across various extracellular conditions, we identified the most and least influential components based on …
Engineering Novel Detection And Treatment Strategies For Bacterial Therapy Of Cancer, Jan T. Panteli
Engineering Novel Detection And Treatment Strategies For Bacterial Therapy Of Cancer, Jan T. Panteli
Doctoral Dissertations
Finding and treating cancer is difficult due to limited sensitivity and specificity of current detection and treatment strategies. Many chemotherapeutic drugs are small molecules that are limited by diffusion, making it difficult to reach cancer sites requiring high doses that lead to systemic toxicity and off-target effects. Tomographic detection techniques, like PET, MRI and CT, are good at identifying macroscopic lesions in the body but are limited in their ability to detect microscopic lesions. Biomarker detection strategies are extremely sensitive and able to identify ng/ml concentrations of protein, but are poor at discriminating between healthy and disease state levels due …

The Creation Of Α2nc1 Transgenic Drosophila Melanogaster, Jordan Olberding
Mahurin Honors College Capstone Experience/Thesis Projects
The α2 isoform of collagen IV’s noncollagenous 1 domain (α2NC1 or canstatin) has shown promise as an anti-cancer molecule, possessing both angiostatic and pro-apoptotic properties. This work aims to further the knowledge of α2NC1 by conducting a truly in vivo study in which the Gal4-induced endogenous overexpression of α2NC1 in Drosophila melanogaster will be used to assess the effects of α2NC1 upon normal development as well as tumorigenesis. To this end, transgenic fly lines capable of overexpressing α2NC1 were created. Initial overexpression studies indicated no developmental phenotype was caused by abundance of α2NC1. However, future overexpression studies in which α2NC1 …

MicroRNAs are emerging as a hot topic in research, and rightfully so. They show great promise as targets of treatment and as markers for common human diseases, such as cancer and metabolic diseases. In this review, we address some of the basic questions regarding micro- RNA function in human disease and the clinical significance of microRNAs. Specifically, micro- RNAs in epigenetics, cancer, and metabolic diseases are discussed, with examples taken from cholangiocarcinoma and nonalcoholic fatty liver disease.

Multidimensional cancer genome analysis and validation has defined Quaking (QKI), a member of the signal transduction and activation of RNA (STAR) family of RNA-binding proteins, as a novel glioblastoma multiforme (GBM) tumor suppressor. Here, we establish that p53 directly regulates QKI gene expression, and QKI protein associates with and leads to the stabilization of miR-20a; miR-20a, in turn, regulates TGFβR2 and the TGFβ signaling network. This pathway circuitry is substantiated by in silico epistasis analysis of its components in the human GBM TCGA (The Cancer Genome Atlas Project) collection and by their gain- and loss-of-function interactions in in vitro and …

BACKGROUND: Regulatory T lymphocytes (Treg) infiltrate human glioblastoma (GBM); are involved in tumor progression and correlate with tumor grade. Transient elimination of Tregs using CD25 depleting antibodies (PC61) has been found to mediate GBM regression in preclinical models of brain tumors. Clinical trials that combine Treg depletion with tumor vaccination are underway to determine whether transient Treg depletion can enhance anti-tumor immune responses and improve long term survival in cancer patients. FINDINGS: Using a syngeneic intracrabial glioblastoma (GBM) mouse model we show that systemic depletion of Tregs 15 days after tumor implantation using PC61 resulted in a decrease in Tregs …

Old Remedies In The Biotechnology Age: Moore V. Regents, Michelle J. Burke, Victoria M. Schmidt
RISK: Health, Safety & Environment (1990-2002)
The California Supreme Court, by excluding a potential remedy, has eliminated many concerns generated by a lower court decision resolving rights to the cell line derived from John Moore's spleen. Yet, the Supreme Court gave little attention to remedies that remain. The authors argue that a constructive trust, a remedy of considerable vintage and great flexibility, could be applied to achieve a just result in such circumstances without affecting the biotechnology world at large.
