Chromatin Pattern Quantification For The Differentiation Of White Blood Cells, Paul Young, Ryan Cordner, Abigail Gordhamer

Annual Research Symposium

Nuclear chromatin patterns have been used historically to distinguish between different developmental stages and lineages of white blood cells. While it is common to characterize cells based on arbitrary ‘open’ or ‘closed’ chromatin patterns, quantification of chromatin data is lacking. By extracting nuclei from a database of white blood cells and running fractal analyses using TWOMBLI, we were able to produce meaningful data quantifying chromatin patterns. Our data were put through a random forest algorithm which grouped each point based on relationship probability. The algorithm compared immature and mature cell types as well as cells of similar maturity and differing …

SMARCB1 loss has long been observed in many solid tumors. However, there is a need to elucidate targetable pathways driving growth and metastasis in SMARCB1-deficient tumors. Here, we demonstrate that SMARCB1 deficiency, defined as genomic SMARCB1 copy number loss associated with reduced mRNA, drives disease progression in patients with bladder cancer by engaging STAT3. SMARCB1 loss increases the chromatin accessibility of the STAT3 locus in vitro. Orthotopically implanted SMARCB1 knockout (KO) cell lines exhibit increased tumor growth and metastasis. SMARCB1-deficient tumors show an increased IL6/JAK/STAT3 signaling axis in in vivo models and patients. Furthermore, a pSTAT3 selective inhibitor, TTI-101, reduces …

Faculty, Staff and Student Publications

β-Lactamases can accumulate stepwise mutations that increase their resistance profiles to the latest β-lactam agents. CMY-185 is a CMY-2-like β-lactamase and was identified in an Escherichia coli clinical strain isolated from a patient who underwent treatment with ceftazidime-avibactam. CMY-185, possessing four amino acid substitutions of A114E, Q120K, V211S, and N346Y relative to CMY-2, confers high-level ceftazidime-avibactam resistance, and accumulation of the substitutions incrementally enhances the level of resistance to this agent. However, the functional role of each substitution and their interplay in enabling ceftazidime-avibactam resistance remains unknown. Through biochemical and structural analysis, we present the molecular basis for the enhanced …

Cancers associated with the oncogenic gammaherpesviruses, Epstein-Barr virus and Kaposi sarcoma herpesvirus, are notable for their constitutive activation of the transcription factor signal transducer and activator of transcription 3 (STAT3). To better understand the role of STAT3 during gammaherpesvirus latency and the B cell response to infection, we used the model pathogen murine gammaherpesvirus 68 (MHV68). Genetic deletion of STAT3 in B cells of CD19cre/+Stat3f/f mice reduced peak MHV68 latency approximately sevenfold. However, infected CD19cre/+Stat3f/f mice exhibited disordered germinal centers and heightened virus-specific CD8 T cell responses compared to wild-type (WT) littermates. To circumvent the systemic immune alterations observed in …

Sugar-Binding And Split Domain Combinations In Repeats-In-Toxin Adhesins From Vibrio Cholerae And Aeromonas Veronii Mediate Cell-Surface Recognition And Hemolytic Activities, Mustafa Sherik, Robert Eves, Shuaiqi Guo, Cameron J Lloyd, Karl E Klose, Peter L Davies

Faculty, Staff and Student Publications

Many pathogenic Gram-negative bacteria use repeats-in-toxin adhesins for colonization and biofilm formation. In the cholera agent Vibrio cholerae, flagellar-regulated hemagglutinin A (FrhA) enables these functions. Using bioinformatic analysis, a sugar-binding domain was identified in FrhA adjacent to a domain of unknown function. AlphaFold2 indicated the boundaries of both domains to be slightly shorter than previously predicted and assisted in the recognition of the unknown domain as a split immunoglobulin-like fold that can assist in projecting the sugar-binding domain toward its target. The AlphaFold2-predicted structure is in excellent agreement with the molecular envelope obtained from small-angle X-ray scattering analysis of …

Microsporidiosis: Reviewing Clinical Presentation And Treatment Strategies, Julienne Zhou, Belinda Liu, Megan Dearmond, David Banach, Brad Haubrich

Annual Research Symposium

Microsporidiosis is an opportunistic infection caused by obligate intracellular pathogens within the taxon Microsporidia. Infection is zoonotic and has been associated with patients experiencing immunodeficiency, though incidence is increasing among other populations. Most commonly, the disease is gastrointestinal, typically by Enterocytozoon bieneusi and less commonly by Encephalitozoon intestinalis. Symptoms present with diarrhea and vomiting, and severe cases can lead to wasting and mortality. While the incorporation of anti-retroviral therapy for HIV patients has significantly decreased mortality in a subset of the vulnerable populations, treatment for microsporidiosis is still not standardized or well explored. Resistance to first-line treatment albendazole is increasing, …

Educational Intervention For Delirium Assessment In Intensive Care Units Using The Confusion Assessment Method, Nathan Nguyen, Kaylee Putney, Alana Whittaker

Annual Research Symposium

Delirium frequently occurs in severely ill adults, leading to worse outcomes and increased duration of intensive care unit (ICU) and hospital stays, along with higher associated expenses. The 2018 clinical practice guidelines for Pain, Agitation, Delirium, Immobility, and Sleep Disruption (PADIS) recommend that all adult ICU patients be regularly assessed for delirium. At Valley Hospital Medical Center, the utilization of Confusion Assessment Method for the ICU (CAM-ICU) for monitoring delirium is infrequent, typically taking place either after the adjustment of sedatives or in response to nursing reports of positive neurologic assessments indicating signs of delirium.

Pharmacognosy And Trichomoniasis: A Scoping Review Protocol, Claire Hartwell, Melanie Arslanian, Brad Haubrich

Annual Research Symposium

Trichomoniasis, also called “trich”, is the most common non-viral sexually transmitted infection (STI). Its etiological agent is the protozoan parasite Trichomonas vaginalis, against which first-line antiparasitics usually work. However, resistance is on the rise. Trich has traditionally been considered a nuisance infection, with many (particularly AMAB patients) being asymptomatic. But research in recent years has begun to unravel correlations of trichomonal infections with a myriad of comorbitidies, including infertility, cancers, the pathogenesis of AIDS, and pelvic inflammatory disease (PID). Between the rise of drug resistance and the incidence of these comorbidities, new treatments are needed. In this work, we are …
