Leveraging Bio-Inspired Molecules For Cancer Theranostics, Douglas S. Macpherson Feb 2023

Leveraging Bio-Inspired Molecules For Cancer Theranostics, Douglas S. Macpherson

Dissertations, Theses, and Capstone Projects

A variety of molecules can be radiolabeled and delivered to a cancer site for the purposes of diagnostics and therapy. Among the most promising of tumor targeting molecules are peptides and antibodies. These bio-inspired molecules can be designed and synthesized to target and respond to cancer cells based on the properties of those cells. Matrix metalloproteinase (MMP) enzymes are over-expressed by some metastatic cancers, in which they are responsible for the degradation and remodeling of the extracellular matrix. In recent years, MMPs have emerged as promising targets for enzyme-responsive diagnostic probes because oligopeptides can be designed to be selectively hydrolyzed …


Neuroplasticity Of The Corticospinal System: Applications Of Neuromodulation-Based Therapies, Alzahraa M. Amer Jun 2021

Neuroplasticity Of The Corticospinal System: Applications Of Neuromodulation-Based Therapies, Alzahraa M. Amer

Dissertations, Theses, and Capstone Projects

The motor cortex and corticospinal tract are necessary for producing skilled movements. I use intermittent theta burst stimulation (iTBS), a high-frequency stimulation protocol known to promote neural plasticity, as a tool to characterize short- and long-term plasticity of the CS system.

Although it is well known that activity-dependent motor cortex (MCX) plasticity produces long-term potentiation (LTP) of local cortical circuits, leading to enhanced motor evoked potentials (MEPs), the effects produced by the corticospinal (CS) projection on spinal cord neurons have not yet been thoroughly studied. In Chapter 2, I determined if the CS tract (CST) is capable of producing LTP …


Parp1-Targeted Radiotherapies, Stephen Jannetti Feb 2020

Parp1-Targeted Radiotherapies, Stephen Jannetti

Dissertations, Theses, and Capstone Projects

Poly-ADP-ribosylation reactions were first reported by Chambon in 1963 as enzymatic activity that increases incorporation of ATP in the presence of nicotinamide mononucleotide. In the decades since that publication, Poly(ADP-ribose)polymerase 1 (PARP1) and the PARP family enzymes have been widely studied. PARP enzymes are currently known to play various roles in mammals, including anti-aging processes, interactions with Breast Cancer Suppressor Protein-1 (BRCA1), and DNA damage repair. A significant focus of PARP1 research has been elucidating its role in DNA damage repair. PARP1 is recruited to repair single strand DNA (ssDNA) breaks, which can become double stranded DNA (dsDNA) breaks if …


Microrna 1207-3p In Prostate Cancer, Dibash Das Feb 2018

Microrna 1207-3p In Prostate Cancer, Dibash Das

Dissertations, Theses, and Capstone Projects

Prostate cancer (PCa) is the most commonly diagnosed male cancer and the second leading cause of cancer-related death for men in the United States. Understanding the molecular mechanisms involved in progression from the asymptomatic androgen-dependent PCa to the lethal castration resistant prostate cancer (CRPC) is a major challenge. MicroRNAs (miRNAs), are known to be dysregulated in PCa. MicroRNA-1207-3p (miR-1207-3p) is encoded by the non-protein coding gene locus PVT1 on the 8q24 human chromosomal region, an established PCa susceptibility locus. However, the role of miR-1207-3p in PCa is unclear. We have discovered that miR-1207-3p is significantly underexpressed in PCa cell lines …
