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 …

Second Generation Phenyloxadiazolyl Methyl Sulfones For Thiol-Specific Bioconjugations, Guillaume Dewaele-Le Roi

Dissertations, Theses, and Capstone Projects

The role of antibody-based molecular agents for diagnosis and therapy of cancer has expanded significantly over the past decades. However, most of these constructs are synthesized using traditional bioconjugation methods based on the random ligations between the molecular cargo and lysine residues within the protein. These non-specific approaches can create poorly defined conjugates with suboptimal immunoreactivity and in vivo performance while Site-specific approaches to antibody bioconjugation based on ligations between maleimides and free cysteine residues have long stood as attractive alternatives. Yet the inherent instability of the thiol-maleimide linkage has fueled the search for new, more stable thiol-reactive prosthetic groups. …

An Acute Respiratory Distress Syndrome Drug Development Collaboration Stimulated By The Virginia Drug Discovery Consortium, John S. Lazo, Ruben M.L. Colunga-Biancatelli, Pavel A. Solopov, John D. Catravas

Bioelectrics Publications

The genesis of most older medicinal agents has generally been empirical. During the past one and a half centuries, at least in the Western countries, discovering and developing drugs has been primarily the domain of pharmaceutical companies largely built upon concepts emerging from organic chemistry. Public sector funding for the discovery of new therapeutics has more recently stimulated local, national, and international groups to band together and focus on new human disease targets and novel treatment approaches. This Perspective describes one contemporary example of a newly formed collaboration that was simulated by a regional drug discovery consortium. University of Virginia, …

Full- Versus Sub-Regional Quantification Of Amyloid-Beta Load On Mouse Brain Sections, Yuu Ohno, Riley Murphy, Matthew Choi, Weijun Ou, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

Extracellular accumulation of amyloid-beta (Aβ) plaques is one of the major pathological hallmarks of Alzheimer's disease (AD), and is the target of the only FDA-approved disease-modifying treatment for AD. Accordingly, the use of transgenic mouse models that overexpress the amyloid precursor protein and thereby accumulate cerebral Aβ plaques are widely used to model human AD in mice. Therefore, immunoassays, including enzyme-linked immunosorbent assay (ELISA) and immunostaining, commonly measure the Aβ load in brain tissues derived from AD transgenic mice. Though the methods for Aβ detection and quantification have been well established and documented, the impact of the size of the …

The Role Of Age Ligand And Rap1a In Myofibroblast Signaling Cascade In Type 2 Diabetes Mellitus-Induced Cardiomyopathic Conditions, Camilla Puglia

Honors Theses

Diabetes is one of the leading causes of death in the United States, taking more than 90,000 lives annually. Type 2 diabetes mellitus-induced cardiac fibrosis is a common condition seen in diabetic patients. The AGE/RAGE signaling cascade has been strongly associated with this supposed cardiac fibrosis along with hyperactive myofibroblasts which excessively remodel extracellular matrix tissue, leading to damaged and enlarged heart muscle tissue. In diabetic patients, Advanced Glycation End Products (AGEs) are produced in abundance and accumulate in the extracellular matrix of heart tissue. To investigate the role of of the AGE ligand on fibroblast behavior, increasing amounts of …

Long-Term Lithium Use In The Younger Population: Do The Benefits Outweigh The Risks? - A Case Report, Seema Shekar, Alexander Garcia, Rachel Shmuts

Stratford Campus Research Day

For decades lithium has been the mainstay treatment for bipolar disorder. While its side effect profile is extensive and varied its most notable adverse effect, and one most feared by treating clinicians, is nephrotoxicity/ end-stage renal disease (ESRD). While the link between long-term lithium use and ESRD has been accepted by the medical community at large for many years, more recent scientific studies call the association into question. In fact, newer studies on the association between Li use and ESRD have shown a negative/inconclusive correlation. Despite this controversy the consensus still remains that ESRD secondary to long-term Li use is …
