VISTA is a premier target for cancer treatment due to its broad expression in many cancer types and enhanced expression upon development of adaptive immune checkpoint resistance. In the CT26 colorectal cancer model, monotherapy of small tumors with anti-VISTA resulted in slowed tumor growth. In a combination therapy setting, large CT26 tumors showed complete adaptive resistance to anti-PD-1/CTLA-4, but inclusion of anti-VISTA led to rejection of half the tumors. Mechanisms of enhanced anti-tumor immunity were investigated using scRNA-seq, multiplex image analysis and flow cytometry of the tumor immune infiltrate. In both treatment models, anti-VISTA upregulated stimulated antigen-presentation pathways and reduced …

After 500 years since the arrival of Christianity in these islands now called the Philippines, we are still being summoned to inculturate our faith. This dialogue between faith and culture takes place more effectively if done in our local language—Tagalog. This challenge is posed concretely to the Catholic Biblical Association of the Philippines in the form of a translation project, with enough Filipino and Filipina biblicists, of the entire Sacred Scriptures, which shall serve theological studies and reflection rooted in the context of our people and society. The belated and posthumous appreciation of Mitchell Dahood, SJ’s magnum opus (Psalms I-III …

Effective therapies are lacking for patients with advanced colorectal cancer (CRC). The CRC tumor microenvironment has elevated metabolic waste products due to altered metabolism and proximity to the microbiota. The role of metabolite waste in tumor development, progression, and treatment resistance is unclear. We generated an autochthonous metastatic mouse model of CRC and used unbiased multi-omic analyses to reveal a robust accumulation of tumoral ammonia. The high ammonia levels induce T cell metabolic reprogramming, increase exhaustion, and decrease proliferation. CRC patients have increased serum ammonia, and the ammonia-related gene signature correlates with altered T cell response, adverse patient outcomes, and …

Androgen receptor (AR) and its splice variants (AR-SVs) promote prostate cancer (PCa) growth by orchestrating transcriptional reprogramming. Mechanisms by which the low complexity and intrinsically disordered primary transactivation domain (AF-1) of AR and AR-SVs regulate transcriptional programming in PCa remains poorly defined. Using omics, live and fixed fluorescent microscopy of cells, and purified AF-1 and AR-V7 recombinant proteins we show here that AF-1 and the AR-V7 splice variant form molecular condensates by liquid-liquid phase separation (LLPS) that exhibit disorder characteristics such as rapid intracellular mobility, coactivator interaction, and euchromatin induction. The LLPS and other disorder characteristics were reversed by a …

Pancreatic ductal adenocarcinoma (PDAC) presents a 5-year overall survival rate of 11%, despite efforts to improve clinical outcomes in the past two decades. Therapeutic resistance is a hallmark of this disease, due to its dense and suppressive tumor microenvironment (TME). Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is a promising local ablative and potential immunomodulatory therapy for PDAC. In this study, we performed RFA in a preclinical tumor-bearing KrasG12D; Trp53R172H/+; Pdx1:Cre (KPC) syngeneic model, analyzed local and abscopal affects after RFA and compared our findings with resected PDAC specimens. We found that RFA reduced PDAC tumor progression in vivo and promoted strong …

Aberrant metabolic functions play a crucial role in prostate cancer progression and lethality. Currently, limited knowledge is available on subtype-specific metabolic features and their implications for treatment. We therefore investigated the metabolic determinants of the two major subtypes of castration-resistant prostate cancer [androgen receptor-expressing prostate cancer (ARPC) and aggressive variant prostate cancer (AVPC)]. Transcriptomic analyses revealed enrichment of gene sets involved in oxidative phosphorylation (OXPHOS) in ARPC tumor samples compared with AVPC. Unbiased screening of metabolic signaling pathways in patient-derived xenograft models by proteomic analyses further supported an enrichment of OXPHOS in ARPC compared with AVPC, and a skewing toward …

Comparison Of In-Vitro 3d Human Embryoids With Current Models For Gastrulation, Jin Park

McKelvey School of Engineering Graduate Student Theses & Dissertations

Gastrulation is an early morphogenetic process that is conserved across most metazoans and lays out the future body plan through the formation and shaping of the three germ layers: endoderm, mesoderm, and ectoderm. Despite its importance, not much is known about the events surrounding human gastrulation that occurs in utero due to ethical and technical limitations on studying human embryos. Therefore, many researchers have devised protocols for creating in vitro models of gastrulation using embryonic stem cells. Initially starting with mouse embryonic stem cells, the field of in vitro embryo models has advanced rapidly, with protocols using human embryonic stem …

Selective And Differential Feeding On Marine Prokaryotes By Mucous Mesh Feeders, Carey P. Sweeney, Kelly R. Sutherland, Anne Thompson

Biology Faculty Publications and Presentations

Microbial mortality impacts the structure of food webs, carbon flow, and the interactions that create dynamic patterns of abundance across gradients in space and time in diverse ecosystems. In the oceans, estimates of microbial mortality by viruses, protists, and small zooplankton do not account fully for observations of loss, suggesting the existence of underappreciated mortality sources. We examined how ubiquitous mucous mesh feeders (i.e. gelatinous zooplankton) could contribute to microbial mortality in the open ocean. We coupled capture of live animals by blue-water diving to sequence-based approaches to measure the enrichment and selectivity of feeding by two coexisting mucous grazer …

UBE3A encodes ubiquitin protein ligase E3A, and in neurons its expression from the paternal allele is repressed by the UBE3A antisense transcript (UBE3A-ATS). This leaves neurons susceptible to loss-of-function of maternal UBE3A. Indeed, Angelman syndrome, a severe neurodevelopmental disorder, is caused by maternal UBE3A deficiency. A promising therapeutic approach to treating Angelman syndrome is to reactivate the intact paternal UBE3A by suppressing UBE3A-ATS. Prior studies show that many neurological phenotypes of maternal Ube3a knockout mice can only be rescued by reinstating Ube3a expression in early development, indicating a restricted therapeutic window for Angelman syndrome. Here, we …

Signaling circuits crucial to systemic physiology are widespread, yet uncovering their molecular underpinnings remains a barrier to understanding the etiology of many metabolic disorders. Here, we identified a copper-linked signaling circuit activated by disruption of mitochondrial function in the murine liver or heart that resulted in atrophy of the spleen and thymus and caused a peripheral white blood cell deficiency. We demonstrated that the leukopenia was caused by α-fetoprotein, which required copper and the cell surface receptor CCR5 to promote white blood cell death. We further showed that α-fetoprotein expression was upregulated in several cell types upon inhibition of oxidative …

Arginine Methylation Of The Pgc-1Α C-Terminus Is Temperature-Dependent, Meryl Mendoza, Mariel Mendoza, Tiffany Lubrino, Sidney Briski, Immaculeta Osuji, Janielle Cuala, Brendan Ly, Ivan Ocegueda, Harvey Peralta, Benjamin A. Garcia, Cecilia I. Zurita-Lopez

We set out to determine whether the C-terminus (amino acids 481-798) of peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1α, UniProt Q9UBK2), a regulatory metabolic protein involved in mitochondrial biogenesis, and respiration, is an arginine methyltransferase substrate. Arginine methylation by protein arginine methyltransferases (PRMTs) alters protein function and thus contributes to various cellular processes. In addition to confirming methylation of the C-terminus by PRMT1 as described in the literature, we have identified methylation by another member of the PRMT family, PRMT7. We performed

Follistatin Regulates The Specification Of The Apical Cochlea Responsible For Low-Frequency Hearing In Mammals, Hei Yeun Koo, Min-A Kim, Hyehyun Min, Jae Yeon Hwang, Meenakshi Prajapati-Dinubila, Kwan Soo Kim, Martin M Matzuk, Juw Won Park, Angelika Doetzlhofer, Un-Kyung Kim, Jinwoong Bok

The cochlea's ability to discriminate sound frequencies is facilitated by a special topography along its longitudinal axis known as tonotopy. Auditory hair cells located at the base of the cochlea respond to high-frequency sounds, whereas hair cells at the apex respond to lower frequencies. Gradual changes in morphological and physiological features along the length of the cochlea determine each region's frequency selectivity, but it remains unclear how tonotopy is established during cochlear development. Recently, sonic hedgehog (SHH) was proposed to initiate the establishment of tonotopy by conferring regional identity to the primordial cochlea. Here, using mouse genetics, we provide in …

Purpose: Foveoschisis involves the pathologic splitting of retinal layers at the fovea, which may occur congenitally in X-linked retinoschisis (XLRS) or as an acquired complication of myopia. XLRS is attributed to functional loss of the retinal adhesion protein retinoschisin 1 (RS1), but the pathophysiology of myopic foveoschisis is unclear due to the lack of animal models. Here, we characterized a novel nonhuman primate model of myopic foveoschisis through clinical examination and multimodal imaging followed by morphologic, cellular, and transcriptional profiling of retinal tissues and genetic analysis.

Methods: We identified a rhesus macaque with behavioral and anatomic features of myopic foveoschisis, …

Creating Equitable And Sustainable Opportunities For Nature Immersion To Support Restoration From Stress Within Mental Health Nursing: A Critical Interpretive Synthesis, Sarah Howes, Paul Warwick

School of Nursing and Midwifery

In the face of global environmental changes threatening health, and despite increased calls for nurses to broker access to nature-based well-being interventions for people with mental health difficulties, there is a surprising absence of literature examining the nature–nursing relationship, inhibiting its inclusion within nursing curricula and practice. This critical interpretive synthesis supports the notion that nature immersion has the capacity to increase positive affect, reduce negative affect, provide restoration from everyday stress, promote meaning-making, enhance belonging, and foster an interest in caring for the natural world. Yet, critical examination of the literature reveals multiple social and environmental inequalities and unmasks …

Effects Of High-Pressure Processing On Cooked Color And Eating Qualities Of Dark-Cutting Beef, Cole Reesman, Gary Sullivan, Mary-Grace C. Danao, Gretchen G. Mafi, Morgan Pfeiffer, Ranjith Ramanathan

Department of Animal Science: Faculty Publications

High meat pH leads to an undercooked or an abnormal pink appearance in fully-cooked product. High-pressure processing (HPP) promotes protein denaturation. The objective was to evaluate the effects of HPP on cooked steak color and sensory attributes of dark-cutting beef. USDA Choice (mean pH = 5.5) and dark-cutting (mean pH = 6.3) strip loin sections were vacuum packaged and treated with 0 (no HPP), 300, 450, and 600 MPa of pressure for 90 s using chilled water. Steaks were randomly assigned to measure external cooked color, Warner- Bratzler shear force, and trained sensory panel. Applying 300 MPa of pressure improved …

Catholic Higher Education And Student Formation In A Post-Roe World: A Modest Proposal For Women’S Personhood And Reproductive Autonomy, M.T. Davila

Religious & Theological Studies Faculty Publications

Student formation is a key missional goal for Catholic colleges and universities. In many instances this involves requiring coursework in theology and ethics that exposes students to the essentials of the tradition and key themes of Christian life such as vocation, marriage, family, work, and society. And yet, historically we fail to consider the changing landscape of life in community, especially for women and other gender minorities. The personhood of women and reproductive autonomy, both topics that have been tangled in the culture war of the abortion debate, is a particular challenge to the goal of formation. The US Supreme …

Still A Private Universe? Community College Students’ Understanding Of Evolution, Meredith A. Dorner, Philip Sadler, Brian Alters

Education Faculty Articles and Research

Background

Measuring what students know and retain about evolution is essential to improving our understanding of how students learn evolution. The literature shows that college students appear to have a poor understanding of evolution, answering questions on various instruments correctly only about half of the time. There is little research regarding evolution understanding among community college students and so this study examines if those students who are enrolled in life science classes, who are assessed using questions based on grade eight standards, show a better understanding of evolutionary principles than younger students and if there are differences in knowledge based …

Investigating The Role Of Vasopressin Receptor 1a Expressing Neurons In Mouse Dorsal Raphe, Tirth Nimishbhai Patel

Theses and Dissertations

Human social interactions heavily impact our physical and mental wellbeing. Arginine-vasopressin (Avp) and serotonin have both been implicated in modulation of social behaviors ranging from affiliation to aggression. In male mice, Avp neurons in the bed nucleus of stria terminalis (BNST) show increased activity during prosocial behavior. BNST sends Avp afferents to the dorsal raphe (DR) in the midbrain, a home to a large portion of serotonin neurons in the mouse brain. Previous data suggests that DR is activated during male prosocial behavior with a female stimulus, and Avp indirectly excites serotonin neurons. We hypothesized that DR contains a population …

Repurposing Ms Immunotherapies For Cidp And Other Autoimmune Neuropathies: Unfulfilled Promise Or Efficient Strategy?, Felix Kohle, Marinos Dalakas, Helmar C Lehmann

Department of Neurology Faculty Papers

Despite advances in the treatment of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and other common autoimmune neuropathies (AN), still-many patients with these diseases do not respond satisfactorily to the available treatments. Repurposing of disease-modifying therapies (DMTs) from other autoimmune conditions, particularly multiple sclerosis (MS) and neuromyelitis optica spectrum disorders (NMOSD), is a promising strategy that may accelerate the establishment of novel treatment choices for AN. This approach appears attractive due to homologies in the pathogenesis of these diseases and the extensive post-marketing experience that has been gathered from treating MS and NMOSD patients. The idea is also strengthened by a number …

Fn14-Directed Dart Nanoparticles Selectively Target Neoplastic Cells In Preclinical Models Of Triple-Negative Breast Cancer Brain Metastasis, Christine P Carney, Anshika Kapur, Pavlos Anastasiadis, Rodney M Ritzel, Chixiang Chen, Graeme F Woodworth, Jeffrey A Winkles, Anthony J Kim

Faculty, Staff and Student Publications

Triple-negative breast cancer (TNBC) patients with brain metastasis (BM) face dismal prognosis due to the limited therapeutic efficacy of the currently available treatment options. We previously demonstrated that paclitaxel-loaded PLGA−PEG nanoparticles (NPs) directed to the Fn14 receptor, termed “DARTs”, are more efficacious than Abraxane—an FDA-approved paclitaxel nanoformulation—following intravenous delivery in a mouse model of TNBC BM. However, the precise basis for this difference was not investigated. Here, we further examine the utility of the DART drug delivery platform in complementary xenograft and syngeneic TNBC BM models. First, we demonstrated that, in comparison to nontargeted NPs, DART NPs exhibit preferential association …

Inborn errors of IFN-γ immunity can underlie tuberculosis (TB). We report three patients from two kindreds without EBV viremia or disease but with severe TB and inherited complete ITK deficiency, a condition associated with severe EBV disease that renders immunological studies challenging. They have CD4+ αβ T lymphocytopenia with a concomitant expansion of CD4-CD8- double-negative (DN) αβ and Vδ2- γδ T lymphocytes, both displaying a unique CD38+CD45RA+T-bet+EOMES- phenotype. Itk-deficient mice recapitulated an expansion of the γδ T and DN αβ T lymphocyte populations in the thymus and spleen, respectively. Moreover, the patients' T lymphocytes secrete small amounts of IFN-γ in …

Chronic Trem2 Activation Exacerbates Aβ-Associated Tau Seeding And Spreading, Nimansha Jain, Caroline A Lewis, Jason D Ulrich, David M Holtzman

2020-Current year OA Pubs

Variants in the triggering receptor expressed on myeloid cells 2 (TREM2) gene are associated with increased risk for late-onset AD. Genetic loss of or decreased TREM2 function impairs the microglial response to amyloid-β (Aβ) plaques, resulting in more diffuse Aβ plaques and increased peri-plaque neuritic dystrophy and AD-tau seeding. Thus, microglia and TREM2 are at a critical intersection of Aβ and tau pathologies in AD. Since genetically decreasing TREM2 function increases Aβ-induced tau seeding, we hypothesized that chronically increasing TREM2 signaling would decrease amyloid-induced tau-seeding and spreading. Using a mouse model of amyloidosis in which AD-tau is injected into the …
