Helping Frontline Workers In Texas-A Framework For Resource Development, Karima Lalani, Meredith O'Neal, Simone Lee Joannou, Bhanumathi Gopal, Tiffany Champagne-Langabeer

Faculty, Staff and Student Publications

First responders disproportionately experience occupational stress when compared to the general population, and COVID-19 has exacerbated this stress. The nature of their duties as law enforcement officers, firefighters, and medics exposes them to repeated trauma, increasing their risk of developing a broad array of mental health issues, including post-traumatic stress disorder (PTSD), substance use disorder (SUD), and compassion fatigue. This paper describes the need for resources for frontline workers and provides a framework for creating and implementing resources. A team of interdisciplinary subject matter experts developed two major resources. The first resource was a 24/7 helpline to support first responders …

Faculty, Staff and Students Publications

Removal of polyploid cells is essential to preventing cancer and restricting tumor growth. A new study published in The EMBO Journal shows assembly of the NEMO-PIDDosome on extra centrioles. Activation of this protein complex leads to NF-κB activation that, in turn, induces NK cell-mediated cell clearance.

Next-Generation Crispr Gene-Drive Systems Using Cas12a Nuclease, Sara Sanz Juste, Emily M Okamoto, Christina Nguyen, Xuechun Feng, Víctor López Del Amo

Faculty, Staff and Student Publications

One method for reducing the impact of vector-borne diseases is through the use of CRISPR-based gene drives, which manipulate insect populations due to their ability to rapidly propagate desired genetic traits into a target population. However, all current gene drives employ a Cas9 nuclease that is constitutively active, impeding our control over their propagation abilities and limiting the generation of alternative gene drive arrangements. Yet, other nucleases such as the temperature sensitive Cas12a have not been explored for gene drive designs in insects. to address this, we herein present a proof-of-concept gene-drive system driven by Cas12a that can be regulated …

Human Cytomegalovirus (HCMV) is the leading infectious congenital infection globally and the most common viral infection in transplant recipients, therefore identifying a vaccine for HCMV is a top priority. Humoral immunity is a correlate of protection for HCMV infection. The most effective vaccine tested to date, which achieved 50% reduction in acquisition of HCMV, was comprised of the glycoprotein B protein given with an oil-in-water emulsion adjuvant MF59. We characterize gB-specific monoclonal antibodies isolated from individuals vaccinated with a disabled infectious single cycle (DISC) CMV vaccine, V160, and compare these to the gB-specific monoclonal antibody repertoire isolated from naturally-infected individuals. …

Outcomes Of Breakthrough Covid-19 Infections In Patients With Hematologic Malignancies, Kelly S Chien, Christine B Peterson, Elliana Young, Dai Chihara, Elizabet E Manasanch, Jeremy L Ramdial, Philip A Thompson

Faculty, Staff and Student Publications

Patients with hematologic malignancies have both an increased risk for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and higher morbidity/mortality. They have lower seroconversion rates after vaccination, potentially leading to inferior coronavirus disease 2019 (COVID-19) outcomes, despite vaccination. We consequently evaluated the clinical outcomes of COVID-19 infections in 243 vaccinated and 175 unvaccinated patients with hematologic malignancies. Hospitalization rates were lower in the vaccinated group when compared with the unvaccinated group (31.3% vs 52.6%). However, the rates of COVID-19-associated death were similar at 7.0% and 8.6% in vaccinated and unvaccinated patients, respectively. By univariate logistic regression, females, older patients, …

Faculty, Staff and Student Publications

Inflammatory breast cancer (IBC) is an aggressive disease with a poor prognosis and a lack of effective treatments. It is widely established that understanding the interactions between tumor-associated macrophages (TAMs) and the tumor microenvironment is essential for identifying distinct targeting markers that help with prognosis and subsequent development of effective treatments. In this study, we present a 3D in vitro microfluidic IBC platform consisting of THP1 M0, M1, or M2 macrophages, IBC cells, and endothelial cells. The platform comprises a collagen matrix that includes an endothelialized vessel, creating a physiologically relevant environment for cellular interactions. Through the utilization of this …

School of Integrative Biological & Chemical Sciences Faculty Publications

Mosquitoes have profoundly affected human history and continue to threaten human health through the transmission of a diverse array of pathogens. The phylogeny of mosquitoes has remained poorly characterized due to difficulty in taxonomic sampling and limited availability of genomic data beyond the most important vector species. Here, we used phylogenomic analysis of 709 single copy ortholog groups from 256 mosquito species to produce a strongly supported phylogeny that resolves the position of the major disease vector species and the major mosquito lineages. Our analyses support an origin of mosquitoes in the early Triassic (217 MYA [highest posterior density region: …

Coronary artery calcification (CAC), a measure of subclinical atherosclerosis, predicts future symptomatic coronary artery disease (CAD). Identifying genetic risk factors for CAC may point to new therapeutic avenues for prevention. Currently, there are only four known risk loci for CAC identified from genome-wide association studies (GWAS) in the general population. Here we conducted the largest multi-ancestry GWAS meta-analysis of CAC to date, which comprised 26,909 individuals of European ancestry and 8,867 individuals of African ancestry. We identified 11 independent risk loci, of which eight were new for CAC and five had not been reported for CAD. These new CAC loci …

The TMEM127 gene encodes a transmembrane protein of poorly known function that is mutated in pheochromocytomas, neural crest-derived tumors of adrenomedullary cells. Here, we report that, at single-nucleus resolution, TMEM127-mutant tumors share precursor cells and transcription regulatory elements with pheochromocytomas carrying mutations of the tyrosine kinase receptor RET. Additionally, TMEM127-mutant pheochromocytomas, human cells, and mouse knockout models of TMEM127 accumulate RET and increase its signaling. TMEM127 contributes to RET cellular positioning, trafficking, and lysosome-mediated degradation. Mechanistically, TMEM127 binds to RET and recruits the NEDD4 E3 ubiquitin ligase for RET ubiquitination and degradation via TMEM127 C-terminal PxxY motifs. Lastly, increased cell …

Revisiting The Master Food Volunteer Program: Examining How To Enhance Nutrition Education In The United States, Stacey Viera, Lindsey Haynes-Maslow

Journal of Extension

America’s diet-related illness crisis intersects with a lack of nutrition literacy, nutrition security, and systemic inequities. The Cooperative Extension Service’s (CES) national infrastructure could potentially provide equitable access to quality nutrition education in the US utilizing a Master Food Volunteer (MFV) model. This research brief examined preliminary evidence for the MFV model as a support for CES agents and paraprofessionals, and results show a paucity of evidence. Further research and a pilot program with pre-established measures for health-related knowledge and behaviors could elucidate the model’s potential to increase equitable access to evidence-based programming, nutrition, and implementation guidance.

Bisphenol-A And Phthalate Metabolism In Children With Neurodevelopmental Disorders, T Peter Stein, Margaret D Schluter, Robert A Steer, Xue Ming

Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: The etiology of autism spectrum (ASD) and Attention Deficit/Hyperactivity (ADHD) disorders are multifactorial. Epidemiological studies have shown associations with environmental pollutants, such as plasticizers. This study focused on two of these compounds, the Bisphenol-A (BPA) and Diethylhexyl Phthalate (DEHP). The major pathway for BPA and DEHP excretion is via glucuronidation. Glucuronidation makes insoluble substances more water-soluble allowing for their subsequent elimination in urine.

HYPOTHESIS: Detoxification of these two plasticizers is compromised in children with ASD and ADHD. Consequently, their tissues are more exposed to these two plasticizers.

METHODS: We measured the efficiency of glucuronidation in three groups of children, …

Pathogen-Driven Crispr Screens Identify Trex1as A Regulator Of Dna Self-Sensing During Influenza Virus Infection, Cason R King, Yiping Liu, Katherine A Amato, Grace A Schaack, Clayton Mickelson, Autumn E Sanders, Tony Hu, Srishti Gupta, Ryan A Langlois, Judith A Smith, Andrew Mehle

Faculty, Staff and Student Publications

Host:pathogen interactions dictate the outcome of infection, yet the limitations of current approaches leave large regions of this interface unexplored. Here, we develop a novel fitness-based screen that queries factors important during the middle to late stages of infection. This is achieved by engineering influenza virus to direct the screen by programming dCas9 to modulate host gene expression. Our genome-wide screen for pro-viral factors identifies the cytoplasmic DNA exonuclease TREX1. TREX1 degrades cytoplasmic DNA to prevent inappropriate innate immune activation by self-DNA. We reveal that this same process aids influenza virus replication. Infection triggers release of mitochondrial DNA into the …

An Evolutionary Pathway For Coping With Emerging Infectious Disease, Scott Lyell Gardner, Daniel R. Brooks, Walter A. Boeger, Eric P. Hoberg

Zea E-Books Collection

Emerging infectious disease (EID) represents an existential threat to humanity. EIDs are increasing in frequency and impact because of climate change and other human activities. We are losing the battle against EIDs because of improper assessment of the risk of EID. This stems from adherence to a failed paradigm of pathogen-host associations that suggests EIDs ought to be both unpredictable and rare. That, in turn, leads to policies suggesting that crisis response is the best we can do. Real-time and phylogenetic assessments show EIDs to be neither rare nor unpredictable—this is the parasite paradox that shows the failures of the …
