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 …

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 …

In Vitro Investigation Of Tumor Selective Piperidones As Therapeutic Agents Against Leukemia Cancer Cells, Lisett Contreras

Open Access Theses & Dissertations

Cancer is a continuous global health issue. It is the second leading cause of death behind heart disease. Disparities across the emergence of cancer and resulting fatalities raise the importance of researching the disease. Treatments are available for certain types of cancers. However, these are typically accompanied by residual problems including side effects and the possibility for relapse. Some treatments attack all cells, leading to unwarranted side effects that make the possibility of living a comfortable life nearly impossible. Other treatments are specific to certain genetic alterations, making them only useful for a small percentage of patients. Not one treatment …

The Prohibitin Protein Complex Promotes Mitochondrial Stabilization And Cell Survival In Hematologic Malignancies, Elisa Robles Escajeda

Open Access Theses & Dissertations

Lymphocyte proliferation and differentiation is coordinated with high precision in healthy humans and is vital to maintaining a normal immune system. Imbalance of these events can result in the development of autoimmune diseases, immunodeficiencies and hematopoietic malignancies. These pathologies, specifically leukemia and lymphoma have a high incidence of relapse and mortality due to limited treatment options. Therefore, there is a critical need to characterize the signal transduction pathways and understand molecular hallmarks that mediate T cell activation in order to develop new strategies for diagnosis and treatments of these diseases.
