Bis-Indolyl Compounds And The Induction Of Apoptosis In T98g Glioblastoma Multiforme Cells, Margot C. Brown
Bis-Indolyl Compounds And The Induction Of Apoptosis In T98g Glioblastoma Multiforme Cells, Margot C. Brown
Seton Hall University Dissertations and Theses (ETDs)
1,1-bis(3’idolyl)-1(aryl)methane compounds (BIM compounds) have been shown to have anti-cancer properties in colon cancer, bladder cancer, and leukemia cells. The purpose of this work was to determine if BIM compounds could be an effective treatment of glioblastoma multiforme. Sulforhodamine B (SRB) assays showed that 20µM of the BIM compounds could inhibit cellular proliferation of the T98G glioblastoma multiforme cell line over 72 hours. Then immunoblotting was used to analyze the molecular pathway induced by BIM compounds. An increase in the expression of both BAX and cleaved caspase 3 suggest BIM compounds activate programmed cell death, or apoptosis in glioblastoma cells. …

A Functional Three-Dimensional Microphysiological Model Of Myeloma Bone Disease, Richard Visconti

Multiple myeloma (MM) is a hematologic cancer caused by a mature B cell neoplasm, or plasmacytoma, that infiltrates the skeleton at several sites. The disease is characterized by uninhibited transformed plasma cell proliferation that disrupts skeletal homeostasis leading to decreased bone modeling and increased bone resorption. Osteolytic lesions (OL) or voids left in the bone, remain long after the treatment of the cancer and indicate disease progression to myeloma bone disease (MBD). Current combinatorial MM therapies inhibit malignant plasma cell proliferation, slow the progression towards MBD, and increase the mean five-year survival rate, but do little to improve osteoblastic function …

Hypoxia is an imbalance in oxygen delivery and oxygen consumption, ultimately affecting cell survival. Low levels of oxygen diminish adenosine triphosphate synthesis resulting from a decline in oxidative phosphorylation in the mitochondria, therefore inducing apoptosis and cell death. To create a hypoxia mimicked environment, we used hypoxia mimetic compounds cobalt and nickel to treat human neuroblastoma (NMB) cells. Using hypoxic mimic human neuronal cell models, we examined and compared the effects of compound-induced hypoxia on NMB cell proliferation. The cells were treated with 100mM and 300mM concentrations of each compound at 24- and 48-hour intervals. To investigate cell proliferation, the …
The Rational Design, Synthesis, Characterization, And Biological Evaluation Of Cancer-Targeting Immunostimulatory Peptide-Protein Conjugates And Tripeptides, Keith Smith
Seton Hall University Dissertations and Theses (ETDs)
With the advent of cancer immunotherapy and the rise in applications of synthetic biologics, there has been a steady decline in the incidence of cancer. Despite this trend, there is an anticipated 1.7 million new cancer cases with an estimated 610,000 deaths expected by the end of 2018.2 Therefore, the call for continued efforts in creating more effective treatment options are still in high demand. In this thesis, the rational design of a semi-synthetic cancer-targeting immunostimulatory peptide-protein bioconjugate—using N-succinimidyl carbamate chemistry is described. This bio-orthogonal chemistry approach was used to conjugate the synthetic Pep42, cancer-targeting peptide (CTP) and the immunostimulatory …

Fluorescently Labeled Sirnas And Their Theranostic Applications In Cancer Gene Therapy, Stephen David Kozuch
Seton Hall University Dissertations and Theses (ETDs)
Gene therapy has emerged as a promising precision nano-medicine strategy in the treatment of numerous diseases including cancer. At the forefront of its utility are the applications of short-interfering RNA (siRNA), that silence oncogenic mRNA expression leading to cancer cell death through the RNA interference (RNAi) pathway. Despite the therapeutic potential, siRNAs are limited by poor pharmacological properties, which has hindered their translation into the clinic. Recent studies, however, have highlighted the applications of modified siRNAs, including the use of fluorescent probes and siRNA nanostructures in cancer detection and treatment. The siRNAs reported in this thesis are designed to target …

The killer peptide sequence D-(KLAKLAK)2 has been originally designed and developed as an antibacterial agent. Despite having excellent cytotoxicity towards bacteria, this sequence maintains low cell cytotoxity in malignant mammalian cell types such as cancer. The chemical basis for its selectivity has been attributed to its poly(cationic) amphiphilic nature, which facilitates cell permeability across the negatively charged bacterial membrane, but with limited permeability across the zwitterionic membrane of mammalian cells. The positively charged D-(KLAKLAK)2 sequence has been found to accumulate on the surface of the mitochondria causing dissipation of the negatively charged mitochondrial membrane potential. This charge disruption …
Human Neuroblastoma Adaptation To Cobalt Chloride-Induced Hypoxia, Conor Mcauliffe
Human Neuroblastoma Adaptation To Cobalt Chloride-Induced Hypoxia, Conor Mcauliffe
Seton Hall University Dissertations and Theses (ETDs)
Hypoxia is a frequent characteristic of the solid tumor microenvironment, which occurs when cancer cells lack adequate access to oxygen. By selecting for cells that can adapt to and grow in low oxygen conditions, tumor hypoxia contributes to a more aggressive and invasive cancer phenotype that portends a poor clinical outcome. While many aspects of the cellular response to hypoxia have been explored, the roles of some factors have not been fully explained. Cell signaling factors, including signal transducer and activator of transcription 3 (STAT3), the mu opioid receptor (MOR), and the delta opioid receptor (DOR), as well as changes …
Poly(Arginine) Derived Cancer-Targeting Peptides For The Development Of A Cancer-Targeted Gene Therapy Approach In Hepg2 Liver Cancer Cells, Stesha C. Joseph
Poly(Arginine) Derived Cancer-Targeting Peptides For The Development Of A Cancer-Targeted Gene Therapy Approach In Hepg2 Liver Cancer Cells, Stesha C. Joseph
Seton Hall University Dissertations and Theses (ETDs)
Cancer is a disease that has eluded medicinal approaches for many years and as a result new and improved therapeutic approaches are in constant demand. Although chemotherapy and radiation treatments have assisted in suppressing the growth of tumors, their poor selectivity and efficacy are major limitations for effective therapy en route towards the development of a cure for the cancer epidemic. With the mission of conquering cancer at heart, researchers have pursued a new form of cancer therapy, aptly named, a cancer targeting approach. This method revolves around the selection of a suitable biomarker, typically a cell surface receptor …

Branching Into Rnai: Synthesis, Characterization And Biology Of Branch And Hyperbranch Sirnas, Anthony Muriithi Maina
Seton Hall University Dissertations and Theses (ETDs)
The cancer epidemic continues to afflict millions of humans world-wide each year and despite a renewed hope with the development of new and improved forms of therapy, a cure for cancer remains an elusive goal. This is partly related to the rise of resilient forms of tumors that have evolved with resistance towards conventional chemotherapy and radiation treatments. Moreover, these non-specific therapeutic regimens are highly toxic, leading to severe immunosuppressive effects which poisons the body and compromises the road towards remission. In an effort to mitigate these limitations, cancer-targeting approaches are currently experiencing a renaissance in the translation of new …
