Importance Of Understanding Genetic Predisposition, Andrew Carter

Thinking Matters Symposium

Hypersensitivity reactions can be sudden and are often fatal. Many of these reactions occur as a result of allergies to prescribed medication. Adverse drug reactions or (ADR’s) were show in a recent study to affect over 6% of hospitalized patients and resulted in over 100,000 deaths a year in the US alone. This poster will review the importance of understanding genetic predisposition, through articles about possible genetic causes of allergies to penicillin and other beta-lactams. Changes in a specific HLA gene located on chromosome 6 showed a correlation to penicillin reactions in over 600,000 participants. Another study found a conclusive …

Isoprene Production From Municipal Wastewater Biosolids By Engineered Archaeon Methanosarcina Acetivorans, Sean Carr, Jared Aldridge, Nicole R. Buan

Department of Biochemistry: Faculty Publications

Wastewater biosolids are a promising feedstock for production of value-added renewable chemicals. Methane-producing archaea (methanogens) are already used to produce renewable biogas via the anaerobic treatment of wastewater. The ability of methanogens to efficiently convert dissolved organic carbon into methane makes them an appealing potential platform for biorefining using metabolic engineering. We have engineered a strain of the methanogen Methanosarcina acetivorans to produce the volatile hemiterpene isoprene in addition to methane. The engineered strain was adapted to grow in municipal wastewater through cultivation in a synthetic wastewater medium. When introduced to municipal wastewater the engineered methanogens were able to compete …

Development Of Miriplatin-Loaded Nanoparticles Against Non-Small Cell Lung Cancer, Zhongyue Yuan, Zizhao Xu, Xin Guo

Graduate and Professional Student Research Showcase

Lung cancer claims the highest mortality and the second-most new cases among all oncological diseases. NSCLC accounts for approximately 85% of all newly diagnosed lung cancers. Although platinum-based drugs are standard first-line chemotherapy for stage IIIB/IV NSCLC, accumulating reports have shown the failure of conventional platinum-based regimens due to drug resistance. Miriplatin is a lipophilic anti-cancer drug that has been approved in Japan for transcatheter arterial chemoembolization treatment of hepatocellular carcinoma. Lipid-based nanoparticles such as liposomes, micelles, and solid lipid nanoparticles (SLNs) can encapsulate anti-cancer drugs to improve their water solubility and bioavailability.

Structural Basis For Clostridium Perfringens Enterotoxin Targeting Of Claudins At Tight Junctions In Mammalian Gut, Alex J. Vecchio, Sewwandi S. Rathnayake, Robert M. Stroud

Department of Biochemistry: Faculty Publications

The bacterium Clostridium perfringens causes severe, sometimes lethal gastrointestinal disorders in humans, including enteritis and enterotoxemia. Type F strains produce an enterotoxin (CpE) that causes the third most common foodborne illness in the United States. CpE induces gut breakdown by disrupting barriers at cell–cell contacts called tight junctions (TJs), which are formed and maintained by claudins. Targeted binding of CpE to specific claudins, encoded by its C-terminal domain (cCpE), loosens TJ barriers to trigger molecular leaks between cells. Cytotoxicity results from claudin-bound CpE complexes forming pores in cell membranes. In mammalian tissues, ∼24 claudins govern TJ barriers—but the basis for …

Biological membranes define the boundaries of cells and compartmentalize the chemical and physical processes required for life. Many biological processes are carried out by proteins embedded in or associated with such membranes. Determination of membrane protein (MP) structures at atomic or near-atomic resolution plays a vital role in elucidating their structural and functional impact in biology. This endeavor has determined 1198 unique MP structures as of early 2021. The value of these structures is expanded greatly by deposition of their three-dimensional (3D) coordinates into the Protein Data Bank (PDB) after the first atomic MP structure was elucidated in 1985.
