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. …
Investigating The Pi3k/Akt/Atm Pathway, Telomeric Dna Damage, T Cell Death, And Crispr/Cas9-Mediated Gene Editing During Acute And Chronic Hiv Infection, Sushant Khanal
Electronic Theses and Dissertations
Human Immunodeficiency Virus (HIV) infection initiates major metabolic and cell- survival complications. Anti-retroviral therapy (ART) is the current approach to suppress active HIV replication to a level of undetected viral load, but it is not a curative approach. Newer and sophisticated gene editing technologies could indeed be a potent antiviral therapy to achieve a clinical sterilization/cure of HIV infection. Chronic HIV patients, even under a successful ART regimen, exhibit a low-grade inflammation, immune senescence, premature aging, telomeric DNA attrition, T cell apoptosis, and cellular homeostasis. In this dissertation, we investigated CD4 T cell homeostasis, degree of T cell apoptosis, an …
Exploring The Anticancer Mechanism Of Thienopyrazole Derivative Tpz-1 In Acute Myeloid Leukemia, Jessica Dyanne Hess
Exploring The Anticancer Mechanism Of Thienopyrazole Derivative Tpz-1 In Acute Myeloid Leukemia, Jessica Dyanne Hess
Open Access Theses & Dissertations
Anticancer drug discovery is a time and resource-consuming process for which exceedingly reliable and efficient modern approaches are needed. Phenotypic drug screenings can generate highly potent and innovative drug candidates; however, deconvolution of the drugâ??s target often presents significant barriers to drug development. To overcome this hurdle, we have originally combined in vitro and in silico analyses to uncover the molecular mechanism(s) driving the anticancer activity of the uniquely structured small molecule drug candidate, Tpz-1. Our study revealed that Tpz-1 is a multitargeted agent which induces the programmed death of HL-60 acute myeloid leukemia cells primarily through disruption of microtubule …
A Functional Study Of Topological Dna Problem In Human T Cells During Chronic Viral Infection, Xindi Dang
A Functional Study Of Topological Dna Problem In Human T Cells During Chronic Viral Infection, Xindi Dang
Electronic Theses and Dissertations
T cells play an important role in adaptive immune system against viral infections, while premature aging and dysfunction of T cells induced by unrepaired DNA damages are always non-negligible snags during the long-term of fighting with chronic viral infections, such as Hepatitis B virus (HBV), Hepatitis C virus (HCV) or Human Immunodeficiency Virus (HIV) infection. In this dissertation, we investigated the role of topological DNA damage in reprogramming telomeric DNA damage responses (DDR), mitochondrial metabolisms, and T cell functions using CD4+ T cells derived from individuals with chronic viral infections or healthy subjects treated with topoisomerase inhibitors. The healthy human …
The Effects Of Polymorphisms Of Viral Protein R Of Hiv-1 On The Induction Of Apoptosis In Primary Cells And The Characterization Of Twelve Novel Bacillus Anthracis Bacteriophage, Jacob D. Fairholm
Theses and Dissertations
Viral protein r (Vpr) of Human immunodeficiency virus type 1 (HIV-1) plays an important role in the ability of the virus to infect cells and cause disease. Two polymorphisms to Vpr have been shown to result in differences in disease progression in infected individuals. R36W tends to result in rapid disease progression while R77Q results in long-term non-progression. In order to better understand how these polymorphisms result in these different disease phenotypes, our lab has recently shown that in cell culture, the R36W polymorphism results in increased viral replication and greater induction of cell death. On the other hand, infection …
Targeting Delivery Of Bcl-2 Family Protein Inhibitor Has The Potential To Treat Cancer And Fibrosis, Mohammad Nurul Huda
Targeting Delivery Of Bcl-2 Family Protein Inhibitor Has The Potential To Treat Cancer And Fibrosis, Mohammad Nurul Huda
Open Access Theses & Dissertations
Apoptosis is a naturally occurring cell death mechanism to remove the selective cell population. B-cell leukemia/lymphoma-2 (BCL-2) family protein plays a critical role in activating the upstream apoptosis signaling pathway, primarily the intrinsic apoptosis pathway. The BCL-2 family consists of both pro-and anti-apoptotic proteins, which are structurally and functionally similar, containing up to four BCL-2 homologies (BH) motifs (BH1-4). Defecting apoptosis along this signaling pathway can lead to various events, including malignant cell transformation, tumor metastasis, tissue fibrosis, and drug resistance. In fibrosis, the aberrant apoptosis signaling also activates multiple effector proteins and growth factors, such as TGF-β, CTGF, and …
