Myeloid derived suppressor cells (MDSCs) are key regulators of immune responses and correlate with poor outcomes in hematologic malignancies. Here, we identify that MDSC mitochondrial fitness controls the efficacy of doxorubicin chemotherapy in a preclinical lymphoma model. Mechanistically, we show that triggering STAT3 signaling via β2-adrenergic receptor (β2-AR) activation leads to improved MDSC function through metabolic reprogram- ing, marked by sustained mitochondrial respiration and higher ATP generation which reduces AMPK signaling, altering energy metabolism. Furthermore, induced STAT3 signaling in MDSCs enhances glutamine consumption via the TCA cycle. Metabolized glutamine generates itaconate which downregulates mitochondrial reactive oxygen species via regulation of …

Genomic Analysis Of Seven Mycobacteriophages Identifies Three Novel Species With Differing Phenotypic Stabilities, Laura O'Connell, Aidan Coffey Prof., Jim O'Mahony

Department of Biological Sciences Publications

Recently, case studies have been published regarding the application of mycobacteriophage (MP) therapy (MPT) in patients with multi-antibiotic-resistant infections. A major limitation in the development of MPT is the paucity of therapeutically useful MP. As there are approximately 10,000 MP that have yet to be sequenced, it is possible that characterization of this cohort would increase the repertoire of useful MP. This study aims to contribute to such a strategy, by characterizing a cohort of 7 mycobacteriophages. Sequencing analyses revealed that the MP have unique sequences, and subsequent gene annotation revealed differences in gene organization. Notably, MP LOCARD has the …

Perceived And Real Water Competency And Drowning Risk Among Adults, Teresa Stanley, Kevin Moran, Dawn Garbett, Alan Ovens Mar 2024

Perceived And Real Water Competency And Drowning Risk Among Adults, Teresa Stanley, Kevin Moran, Dawn Garbett, Alan Ovens

International Journal of Aquatic Research and Education

Traditionally, public understanding of drowning survival has focused on swimming capacity, often measured by how far a person can swim. With respect to the high incidence of adult drowning in high-income countries, using the more inclusive concept of water competency may yield a more comprehensive explanatory framework for understanding the reasons behind these drownings. Any competency base required to survive a drowning situation is dynamic, complex, and multi-faceted. Furthermore, perceptions of risk and capacity to cope with that risk are likely to be pivotal to the avoidance of drowning. Adults’ perceived water competence was measured against their actual water competence …

Blocking The Dimerization Of Polyglutamine-Expanded Androgen Receptor Protects Cells From Dht-Induced Toxicity By Increasing Ar Turnover, Allison Lisberg, Yuhong Liu, Diane E. Merry

Department of Biochemistry and Molecular Biology Faculty Papers

Spinal and bulbar muscular atrophy (SBMA) is a neuromuscular degenerative disease caused by a polyglutamine expansion in the androgen receptor (AR). This mutation causes AR to misfold and aggregate, contributing to toxicity in and degeneration of motor neurons and skeletal muscle. There is currently no effective treatment or cure for this disease. The role of an interdomain interaction between the amino- and carboxyl-termini of AR, termed the N/C interaction, has been previously identified as a component of androgen receptor-induced toxicity in cell and mouse models of SBMA. However, the mechanism by which this interaction contributes to disease pathology is unclear. …

Diverse patterns of climate and edaphic factors challenge detection of soil property change in the US Great Plains. Because detectable soil change can take decades, insights into the trajectory of soil properties frequently require long-term site monitoring and, where available, associated soil archives to enable comparisons with initial or baseline states. Unfortunately, few multi-decadal soil change investigations have been conducted in this region. Here, we document effects of dryland cropping on a suite of soil properties by comparing matched historic (1947) and contemporary (2018) soil samples from the Haas Soil Archive at three sites in the US Great Plains: Moccasin, …

Undergraduate Biology Lecture Courses Predominantly Test Facts About Science Rather Than Scientific Practices, Crystal Uminski, Sara M. Burbach, Brian A. Couch

School of Biological Sciences: Faculty Publications

Scientific practices are the skills used to develop scientific knowledge and are essential for careers in science. Despite calls from education and government agencies to cultivate scientific practices, there remains little evidence of how often students are asked to apply them in undergraduate courses. We analyzed exams from biology courses at 100 institutions across the United States and found that only 7% of exam questions addressed a scientific practice and that 32% of biology exams did not test any scientific practices. The low occurrence of scientific practices on exams signals that undergraduate courses may not be integrating foundational scientific skills …
