Treponema Denticola Synthesizes C-Di-Amp And Encodes The Cdaa-Type Diadenylate Cyclase Cdaa, Claire R. O'Brien
Treponema Denticola Synthesizes C-Di-Amp And Encodes The Cdaa-Type Diadenylate Cyclase Cdaa, Claire R. O'Brien
Theses and Dissertations
Periodontitis is a form of oral disease characterized by dysbiosis of the oral microbiome, leading to inflammation, bone resorption, and in severe cases, entire tooth loss, affecting 42% of adults in the US. One of the bacteria most associated with periodontal disease progression is Treponema denticola (Td), an oral spirochete which inhabits the mouth in small quantities during health but which can dominate the biofilms that form during periodontal disease. The ability of Td to survive in a disease environment and contribute to the progression of disease requires the use of robust signaling networks. Analysis of Td cultures …
Protacs – A Novel And Rapidly Developing Field Of Targeted Protein Degradation, Hannah R. Gatley
Protacs – A Novel And Rapidly Developing Field Of Targeted Protein Degradation, Hannah R. Gatley
Theses and Dissertations
There is a continued need for new technology and strategies for tackling cancer and other diseases, and within the current century a novel therapeutic strategy has emerged in the realm of targeted protein degradation called Proteolysis-Targeting Chimeras (PROTACs). This technology specifically targets and degrades disease-causing proteins via the ubiquitin-proteasome system, and has seen an explosion of research and intrigue in both academia and industry over the past two decades. The diversity of PROTAC classes based on the E3 ligase recruiting ligand and the target protein allows for a universal molecular structure that can be customized for a specific target and …
Observing Ceramide Pathway With Ferroptosis Via Mia Paca-2 Cell Treatment With Rsl3, Tazrin Rahman
Observing Ceramide Pathway With Ferroptosis Via Mia Paca-2 Cell Treatment With Rsl3, Tazrin Rahman
Auctus: The Journal of Undergraduate Research and Creative Scholarship
Composed of sphingosine and a fatty acid, ceramides are lipid molecules that serve as key metabolic signaling molecules of a sphingolipid pathway. While it acts as a precursor of complex sphingolipids, inducing ceramide generation can cause cell stress leading to subsequent cell death via apoptosis, necrosis, and even mitophagy. With regards to cell death specifically, a novel form of regulated cell death, ferroptosis, has recently been recognized of necrotic nature. Its unique morphological features and distinct properties have been observed over the last several decades; however, the molecular features were not identifiable as pure evidence of cell death, until recently …
The Type Iv Pilus Secretin Bfpb: Structural Analysis And Binding Interactions, Janay I. Little
The Type Iv Pilus Secretin Bfpb: Structural Analysis And Binding Interactions, Janay I. Little
Theses and Dissertations
Enteropathogenic Escherichia coli (EPEC) causes severe diarrhea in young children. The type IV pilus (T4P) of EPEC, known as the bundle-forming pilus (BFP), plays an important role in EPEC pathogenesis. T4Ps are a family of surface appendages that are important for adhesion, colonization, biofilm formation, virulence, twitching motility and many other functions. One essential component of the BFP system is the secretin, BfpB. Secretins are a large family of integral outer membrane proteins found in T4Ps as well as type II and type III secretion systems, and filamentous phages. Details of the secretin structure have been limited to the overall …
Structural Analysis Of Predicted Proteins Using Alphafold, Brydon P. Wall
Structural Analysis Of Predicted Proteins Using Alphafold, Brydon P. Wall
Undergraduate Research Posters
The function of around 67% of predicted proteins from genes in Mycobacteriophage CheetoDust can not be confidently predicted using traditional techniques and can only be functionally labeled “hypothetical proteins”. However, a new approach using AlphaFold, an artificial intelligence tool to generate a structural prediction from a sequence, can take advantage of structurally conserved regions that were previously obfuscated to gain new insights and visualize data in new ways.
Since amino acid sequences are more conserved than its corresponding DNA sequence, amino acid sequences are used when predicting the function of the corresponding translated protein. Until recently, predicting structure from an …
Gestational Vulnerability To Ozone Air Pollution - A Placental Story, Vishnupriya Alavala, Sarah Brent, Russell Hunter, Matthew J. Campen, Andrew Ottens
Gestational Vulnerability To Ozone Air Pollution - A Placental Story, Vishnupriya Alavala, Sarah Brent, Russell Hunter, Matthew J. Campen, Andrew Ottens
Undergraduate Research Posters
About 99% of the global population resides in areas with air pollution surpassing World Health Organization standards. Air pollution is associated with adverse neonatal health outcomes such as low fetal birth weight and an increased risk for maternal pre-eclampsia. A particularly reactive air pollutant is ozone, which forms reactive oxygen species that induce cellular damage. Research exists on the dispersion of reactive oxygen species through the bloodstream leading to fetal vulnerability during pregnancy, specifically via the placenta. Yet, placental and fetal development is a temporal process with varied susceptibility to negative gestational outcomes.
To addressing this gap, our laboratory utilized …
