Undergraduate Theses, Professional Papers, and Capstone Artifacts
Escherichia coli is a highly studied model organism that is tightly tied to the mammalian gastrointestinal system. This microorganism has the capability to be a beneficial gut microbe or a life-threatening pathogen. In this study, the lipid membrane of Escherichia coli was investigated using Matrix-Assisted Laser Desorption/Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS) to observe the change in its composition in aerobic and anaerobic conditions. Evidence of desaturation was discovered in the spectra, though more investigation is needed to understand the metabolic processes and drives that result in this change. Elucidation of these pathways in the future could result in …

Alternative Splicing Regulates The Innate Immune Response To Viral Infection, Luke A. White
Graduate Student Theses, Dissertations, & Professional Papers
Rift Valley fever virus (RVFV) is a mosquito-borne RNA virus that infects humans and livestock in sub-Saharan Africa and the Arabian peninsula, causing disease ranging from a mild flu-like illness to liver damage, blindness, hemorrhagic fever, death, and, especially in livestock animals, high rates of abortive pregnancies. There is no approved vaccine for RVFV, and as a disease with a high rate of spread that causes severe illness, it is listed as a Category A pathogen by the USA CDC. A better understanding of RVFV’s molecular virology will be instrumental to combating RVFV as climate change causes its mosquito host …
Characterization Of The Influences Of Human Cytomegalovirus Glycoprotein O (Go) Expression On Gh/Gl Complexes Assembly And Its Polymorphisms On Cell-Free And Cell-To-Cell Spread, And Antibody Neutralization., Le Z. Day
Graduate Student Theses, Dissertations, & Professional Papers
Human cytomegalovirus (HCMV) is widely spread throughout the world and immunocompromised individuals can suffer severe diseases from HCMV infection. Once the infection is established, HCMV can spread through the body and infect many major somatic cell types. The glycoproteins H and L (gH/gL) on HCMV envelope can be bound by either gO or the UL128-131 proteins to form complexes gH/gL/gO and gH/gL/UL128-131 that are critical for viral entry and spread, and these two complexes are important targets of neutralizing antibodies. Strains of HCMV vary considerably in the levels of gH/gL/gO and gH/gL/UL128-131. gO is one of the most diverse loci …

Cr(V) is a carcinogen that oxidizes guanine aggressively to form spiroiminodihydantion (Sp) and guanidinohydantoin (Gh), both of which contain an unusual hydantoin moiety that cause G→T transversion mutations at a high rate. Endonuclease VIII (nei) can recognize and excise these oxidation products from DNA and is translated as one of five protein products of the Nei operon in Escherichia coli (E. coli). However, the functions of the other four proteins remain unknown. To address this gap in knowledge, we focused on one of the four that immediately precedes nei, the ybgL protein. Previous work by our group has suggested a …
