Faculty, Staff and Students Publications

Transforming growth factor β (TGFβ) signaling pathways are integral for a plethora of biological processes. SMAD2 and SMAD3 are the principal transcriptional effectors of TGFβ superfamily ligands, yet quantitative, genome-wide mapping of their DNA-associated complexes under physiological contexts has remained limited due to the lack of specific, robust models. Here, we generated two versatile epitope-tagged mouse models in which endogenous SMAD2 and SMAD3 proteins are globally tagged with hemagglutinin (HA) and podoplanin (PA) sequences, respectively, enabling high-fidelity profiling of SMAD2 and SMAD3 binding across tissues. To demonstrate the broad application of our models, we exemplified the usage of our lines …

Phip Suppresses Nurd To Enable The Growth Of Swi/Snf-Mutant Cancers, Hayden A Malone, Francisca N De Luna Vitorino, Benjamin A Garcia, Et Al.

2020-Current year OA Pubs

SWI/SNF chromatin remodeling complexes are perturbed in 20% of all cancers and in several developmental disorders, yet the mechanisms by which these mutations dysregulate transcription and drive disease are poorly understood. To both elucidate these mechanisms and identify vulnerabilities caused by these mutations, we leverage genome-wide CRISPR-Cas9 screening in hundreds of cancer cell lines and identify the chromatin reader protein PHIP as a specific dependency in cancers with broadly disrupted SWI/SNF function. Mechanistically, we reveal that PHIP cooperates with SWI/SNF to facilitate transcriptional activation by ubiquitinating and suppressing subunits of the repressive Nucleosome Remodeling and Deacetylase (NuRD) complex. We demonstrate …

Concentration-based fluid biomarkers represent an informative and cost-effective way to detect and monitor Alzheimer's disease (AD) pathology. However, non-AD-related interindividual variation in biofluids can also affect biomarker concentrations. Here, we investigated whether normalization of CSF and plasma biomarkers to reference proteins, such as amyloid-β40 (Aβ40) and non-phosphorylated mid-region tau (np-tau), improves their robustness and reliability of representing AD pathology load. Using the Swedish BioFINDER-2 cohort [n = 1702, 50.7% male, mean (standard deviation) age 68.4 (12.2) years], we compared the associations between tau/Aβ-PET load and fluid biomarkers alone versus biomarkers in a ratio with a reference protein (Aβ40 or np-tau) …

The gut microbiota is crucial to health, yet implementation of microbiota-based therapeutics is limited by the lack of rapid diagnostics. We hypothesize that breath contains gut microbe-derived volatile organic compounds (VOCs) reflecting microbiota composition and metabolism. In healthy children, we found that breath VOC composition (or volatilome), assessed by gas chromatography-mass spectrometry, correlates with gut microbiome composition and function. By capturing exhaled breath from human-stool-colonized and monocolonized gnotobiotic mice, we profiled breath VOCs and discovered that murine breath is also significantly influenced by the gut microbiome. VOCs from cultured gut microbes were identified in vivo in monocolonized gnotobiotic colonized mice. …

Assessing The Impact Of Interprofessional Simulation Training On Perioperative Staff's Confidence In Managing Maternal Hemorrhage, Mallory Duncan, Lidia Vazquez

Scholars Week

Globally, maternal mortality rates remain a critical public health challenge, often related to inadequate healthcare infrastructure in low-income countries. Yet according to the American Journal of Obstetrics and Gynecology (ACOG), maternal mortality rates in the United States are also on the rise, with nearly 32.9 deaths per 100,000 live births. These deaths are largely contributed to maternal hemorrhage (PPH), defined by ACOG as cumulative blood loss of at least 1,000 mL accompanied by symptoms of hypovolemia within 24 hours of the birth process. These findings underscore an urgent need to strengthen the training for perioperative staff in the management of …

Redesigning A Fitness App Interface For Physiological Constrained Users*, Joseph E. Manzanillo

Campus Research Month

As fitness tracking converges with medical monitoring, inclusive design becomes a matter of health equity. This research utilizes a Polar Beat redesign to address exclusionary "sporty" aesthetics that can exclude 300 million colorblind users. Based in Human-Computer Interaction (HCI), the study implements WCAG AA standards and color-blind-verified filters to mitigate data loss during Situational Induced Impairment (SIID), when high-intensity exercise compromises cognitive and visual processing. By optimizing user journeys for Paralympic and geriatric archetypes, this work demonstrates that accessibility is the essential bridge transitioning mobile fitness apps into viable, inclusive instruments for clinical medical use.

Improvement On Word Memory After Transcutaneous Vagus Nerve Stimulation In Mild Traumatic Brain Injuries, Jenna Pfeifer, Tyrell Perrigo, Reesa Williams, Qiang Li

SACAD: Scholarly Activities

Transcutaneous vagus nerve stimulation (tVNS) is a non-invasive neuromodulation treatment technique that has been demonstrated to activate norepinephrinergic areas of the brain supporting neuroplasticity. Research shows that tVNS may enhance cognitive performance such as memory, as it may elicit the release of key neurotransmitters that modulate cognitive performance and memory formation. The current study aims to investigate the effects of tVNS on short-term memory among those with mild traumatic brain injuries (mTBI). Preliminary results show that tVNS has a positive impact on short-term memory in participants with mTBI, evidenced by faster reaction time and higher accuracy in the memory tests. …

Psychosocial Mediators Of A Physical Activity And Dietary Intervention In Pregnant Women With Overweight Or Obesity, Meghan Baruth, Sarah Wilcox, Jihong Liu, Rebecca Schlaff

Faculty Publications

Background

Mediation analyses provide insight into both ‘pieces’ of the mediation chain; they allow us to look into the ‘black box’ that is behavior change. They allow researchers to better understand the ‘how’ of an intervention’s effects and/or the ‘why’ behind why an intervention worked or did not work. The lack of publications in pregnant populations highlights the need for additional studies to be conducted and published. The purpose of this study is to examine the psychosocial mediators of physical activity and dietary outcomes in a sample of pregnant women with overweight or obesity participating in the Health in Pregnancy …
