Associations Between Screen-Based Activities, Physical Activity, And Dietary Habits In Mexican Schoolchildren, Erica G Soltero, Alejandra Jáuregui, Edith Hernandez, Simón Barquera, Edtna Jáuregui, Juan Ricardo López-Taylor, Luis Ortiz-Hernández, Lucie Lévesque, Rebecca E Lee

Children’s Nutrition Research Center Staff Publications

Screen-based activities are associated with increased risk of obesity and contribute to physical inactivity and poor dietary habits. The primary aim of this study was to examine the associations among screen-based activities, physical activity, and dietary habits in school-aged children in Guadalajara, Puerto Vallarta, and Mexico City, Mexico. The secondary aim was to examine these associations across sex. The School Physical Activity and Nutrition survey was used to assess screen-based activities (TV watching, video game use, computer use), physical activity, and dietary habits. Organized activity/sports participation, unhealthy dietary habits, and household income were correlated with screen-based activities. While TV watching …

Sars-Cov-2 Viral Proteins Nsp1 And Nsp13 Inhibit Interferon Activation Through Distinct Mechanisms, Christine Vazquez, Sydnie E Swanson, Seble G Negatu, Mark Dittmar, Jesse Miller, Holly Ramage, Sara Cherry, Kellie A Jurado

Department of Microbiology and Immunology Faculty Papers

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a devastating global pandemic, infecting over 43 million people and claiming over 1 million lives, with these numbers increasing daily. Therefore, there is urgent need to understand the molecular mechanisms governing SARS-CoV-2 pathogenesis, immune evasion, and disease progression. Here, we show that SARS-CoV-2 can block IRF3 and NF-κB activation early during virus infection. We also identify that the SARS-CoV-2 viral proteins NSP1 and NSP13 can block interferon activation via distinct mechanisms. NSP1 antagonizes interferon signaling by suppressing host mRNA translation, while NSP13 downregulates interferon and NF-κB promoter signaling by limiting TBK1 …

On The Road From Phenotypic Plasticity To Stem Cell Therapy., Lorraine Iacovitti

Farber Institute for Neuroscience Faculty Papers

In 1981, I published a paper in the first issue of The Journal of Neuroscience with my postdoctoral mentor, Richard Bunge. At that time, the long-standing belief that each neuron expressed only one neurotransmitter, known as Dale's Principle (Dale, 1935), was being hotly debated following a report by French embryologist Nicole Le Douarin showing that neural crest cells destined for one transmitter phenotype could express characteristics of another if transplanted to alternate sites in the developing embryo (Le Douarin, 1980). In the Bunge laboratory, we were able to more directly test the question of phenotypic plasticity in the controlled environment …

School of Graduate Studies Faculty Publications

We modified a Sabin Oral Poliovirus Vaccine (OPV) vector to permit secretion of the antigens of interest with the goal of improving anti-HIV Env humoral responses in a SHIV mucosal immunization composed of DNA and recombinant OPVs. We evaluated stimulation of systemic and mucosal cell-mediated and humoral immunity in Rhesus macaques by two regimens, both involving a prime with a SHIVBG505 DNA construct producing non-infectious particles formulated in lipid nanoparticles, administered in the oral cavity, and two different viral vector boostings, administered in the oral cavity and intestinally. Group 1 was boosted with rMVA-SHIVBG505, expressing SIV Gag/Pol and HIVBG505 Env. …

Left Ventricular Recovery With Explantation Of Continuous-Flow Left Ventricular Assist Device After 5 Years Of Support, Andre Critsinelis, Chitaru Kurihara, Masashi Kawabori, Tadahisa Sugiura, Andrew B Civitello, Jeffrey A Morgan

Faculty, Staff and Students Publications

Mechanical circulatory support may result in sufficient myocardial recovery to allow for explantation of the left ventricular assist device (LVAD). The duration of support associated with left ventricular recovery has generally been 6-12 months. In this report, we present a patient in whom the left ventricle recovered after 5 years of support with a LVAD. Our report demonstrates that long-term monitoring for left ventricular recovery is prudent and may allow for late device explantation.

Objective: The objective of this study was to detect discussions on anthrax-related events and to determine the relevance of thetweets and topics of discussion over 12 months of data collection. Methods: This is an infoveillance study, using tweets in English containing the keyword “Anthrax” and …

Candida Cell‐Surface‐Specific Monoclonal Antibodies Protect Mice Against Candida Auris Invasive Infection, Jonothan Rosario‐Colon, Karen Eberle, Abby Adams, Evan Courville, Hong Xin

School of Graduate Studies Faculty Publications

Candida auris is a multidrug‐resistant fungal pathogen that can cause disseminated bloodstream infections with up to 60% mortality in susceptible populations. Of the three major classes of antifungal drugs, most C. auris isolates show high resistance to azoles and polyenes, with some clinical isolates showing resistance to all three drug classes. We reported in this study a novel approach to treating C. auris disseminated infections through passive transfer of monoclonal antibodies (mAbs) targeting cell surface antigens with high homology in medically important Candida spe-cies. Using an established A/J mouse model of disseminated infection that mimics human candidi-asis, we showed that …

Fructose Causes Liver Damage, Polyploidy, And Dysplasia In The Setting Of Short Telomeres And P53 Loss, Christopher Chronowski, Viktor Akhanov, Doug Chan, Andre Catic, Milton Finegold, Ergün Sahin

Faculty, Staff and Students Publications

Studies in humans and model systems have established an important role of short telomeres in predisposing to liver fibrosis through pathways that are incompletely understood. Recent studies have shown that telomere dysfunction impairs cellular metabolism, but whether and how these metabolic alterations contribute to liver fibrosis is not well understood. Here, we investigated whether short telomeres change the hepatic response to metabolic stress induced by fructose, a sugar that is highly implicated in non-alcoholic fatty liver disease. We find that telomere shortening in telomerase knockout mice (TKO) imparts a pronounced susceptibility to fructose as reflected in the activation of p53, …

The Rice Blast Fungus Morgs1 Functioning In Camp Signaling And Pathogenicity Is Regulated By Casein Kinase Mock2 Phosphorylation And Modulated By Membrane Protein Moemc2, Rui Yu, Xuetong Shen, Muxing Liu, Xinyu Liu, Ziyi Yin, Xiao Li, Wanzhen Feng, Jiexiong Hu, Haifeng Zhang, Xiaobo Zheng, Ping Wang, Zhengguang Zhang

School of Graduate Studies Faculty Publications

GTP-binding protein (G-protein) and regulator of G-protein signaling (RGS) mediated signal transduction are critical in the growth and virulence of the rice blast pathogen Magnaporthe oryzae. We have previously reported that there are eight RGS and RGS-like proteins named MoRgs1 to MoRgs8 playing distinct and shared regulatory functions in M. oryzae and that MoRgs1 has a more prominent role compared to others in the fungus. To further explore the unique regulatory mechanism of MoRgs1, we screened a M. oryzae cDNA library for genes encoding MoRgs1-interacting proteins and identified MoCkb2, one of the two regulatory subunits of the casein kinase (CK) …

The Effect Of Diazepam On Early Neural Stem Cells Proliferative Activity And Hippocampal-Dependent Memory After Traumatic Brain Injury, Van Khanh Doan

University Honors Theses

Traumatic brain injury (TBI) induces an upregulation of neurogenesis in the brain specifically in the hippocampus, an area pertaining to learning and memory formation. Although this upregulated response is intuitively thought to be restorative, previous studies show that the nascent neurons generated after TBI exhibit abnormalities, such as aberrant morphologies and early migrations, which could suggest to be maladaptive. The GABA-A agonist diazepam has been shown to inhibit this upregulation in neurogenesis and normalizes dendrites after TBI. To determine whether this modulation of neurogenesis is ultimately beneficial or detrimental to cognitive recovery, diazepam was administered to C57BI/6J wild-type mice following …

Roles And Regulation Of Satellite Cells In Skeletal Muscle Regeneration, Sydney Vlasman

University Honors Theses

Skeletal muscle has an innate ability to self-regenerate in response to certain stimuli. In the case of trauma, muscle resident stem cells are required to meet the regenerative needs of the tissue. These resident stem cells, called satellite cells (SCs), are crucial in the regenerative process following injury; understanding the major factors which regulate satellite cell activity can provide valuable insight for regenerative medicine. The ability to implement and properly activate satellite cells has immense potential in the treatment of conditions including trauma, degenerative disorders, and age-related sarcopenia. This review will discuss the current understanding of satellite cell-mediated regeneration and …

Nlrp3 Inflammasome Is A Key Driver Of Obesity-Induced Atrial Arrhythmias, Larry Scott, Anke C Fender, Arnela Saljic, Luge Li, Xiaohui Chen, Xiaolei Wang, Dominik Linz, Jilu Lang, Mathias Hohl, Darragh Twomey, Thuy T Pham, Rodrigo Diaz-Lankenau, Mihail G Chelu, Markus Kamler, Mark L Entman, George E Taffet, Prashanthan Sanders, Dobromir Dobrev, Na Li

AIMS: Obesity, an established risk factor of atrial fibrillation (AF), is frequently associated with enhanced inflammatory response. However, whether inflammatory signaling is causally linked to AF pathogenesis in obesity remains elusive. We recently demonstrated that the constitutive activation of the 'NACHT, LRR, and PYD Domains-containing Protein 3' (NLRP3) inflammasome promotes AF susceptibility. In this study, we hypothesized that the NLRP3 inflammasome is a key driver of obesity-induced AF.

METHODS AND RESULTS: Western blotting was performed to determine the level of NLRP3 inflammasome activation in atrial tissues of obese patients, sheep, and diet-induced obese (DIO) mice. The increased body weight in …

The inclusion of infants in the SARS-CoV-2 vaccine rollout is important to prevent severe complications of pediatric SARS-CoV-2 infections and to limit transmission and could possibly be implemented via the global pediatric vaccine schedule. However, age-dependent differences in immune function require careful evaluation of novel vaccines in the pediatric population. Toward this goal, we assessed the safety and immunogenicity of two SARSCoV- 2 vaccines. Two groups of eight infant rhesus macaques (RMs) were immunized intramuscularly at weeks 0 and 4 with stabilized prefusion SARS-CoV-2 S-2P spike (S) protein encoded by mRNA encapsulated in lipid nanoparticles (mRNA-LNP) or the purified S …

Development And Validation Of Machine Learning-Based Race-Specific Models To Predict 10-Year Risk Of Heart Failure: A Multicohort Analysis, Matthew W Segar, Byron C Jaeger, Kershaw V Patel, Vijay Nambi, Chiadi E Ndumele, Adolfo Correa, Javed Butler, Alvin Chandra, Colby Ayers, Shreya Rao, Alana A Lewis, Laura M Raffield, Carlos J Rodriguez, Erin D Michos, Christie M Ballantyne, Michael E Hall, Robert J Mentz, James A De Lemos, Ambarish Pandey

BACKGROUND: Heart failure (HF) risk and the underlying risk factors vary by race. Traditional models for HF risk prediction treat race as a covariate in risk prediction and do not account for significant parameters such as cardiac biomarkers. Machine learning (ML) may offer advantages over traditional modeling techniques to develop race-specific HF risk prediction models and to elucidate important contributors of HF development across races.

METHODS: We performed a retrospective analysis of 4 large, community cohort studies (ARIC [Atherosclerosis Risk in Communities], DHS [Dallas Heart Study], JHS [Jackson Heart Study], and MESA [Multi-Ethnic Study of Atherosclerosis]) with adjudicated HF events. …

Genetic Variation And Recurrent Haplotypes On Chromosome 6q23-25 Risk Locus In Familial Lung Cancer, Anthony M Musolf, Claire L Simpson, Bilal A Moiz, Claudio W Pikielny, Candace D Middlebrooks, Diptasri Mandal, Mariza De Andrade, Michael D Cole, Colette Gaba, Ping Yang, Ming You, Yafang Li, Elena Y Kupert, Marshall W Anderson, Ann G Schwartz, Susan M Pinney, Christopher I Amos, Joan E Bailey-Wilson

Although lung cancer is known to be caused by environmental factors, it has also been shown to have genetic components, and the genetic etiology of lung cancer remains understudied. We previously identified a lung cancer risk locus on 6q23-25 using microsatellite data in families with a history of lung cancer. To further elucidate that signal, we performed targeted sequencing on nine of our most strongly linked families. Two-point linkage analysis of the sequencing data revealed that the signal was heterogeneous and that different families likely had different risk variants. Three specific haplotypes were shared by some of the families: 6q25.3-26 …

Genome-embedded ribonucleotides arrest replicative DNA polymerases (Pols) and cause DNA breaks. Whether mammalian DNA repair Pols efficiently use template ribonucleotides and promote RNA-templated DNA repair synthesis remains unknown. We find that human Polθ reverse transcribes RNA, similar to retroviral reverse transcriptases (RTs). Polθ exhibits a significantly higher velocity and fidelity of deoxyribonucleotide incorporation on RNA versus DNA. The 3.2-Å crystal structure of Polθ on a DNA/RNA primer-template with bound deoxyribonucleotide reveals that the enzyme undergoes a major structural transformation within the thumb subdomain to accommodate A-form DNA/RNA and forms multiple hydrogen bonds with template ribose 2'-hydroxyl groups like retroviral RTs. …

Immune Cells In Lens Injury Repair And Fibrosis, Janice L Walker, A. Sue Menko

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Immune cells, both tissue resident immune cells and those immune cells recruited in response to wounding or degenerative conditions, are essential to both the maintenance and restoration of homeostasis in most tissues. These cells are typically provided to tissues by their closely associated vasculatures. However, the lens, like many of the tissues in the eye, are considered immune privileged sites because they have no associated vasculature. Such absence of immune cells was thought to protect the lens from inflammatory responses that would bring with them the danger of causing vision impairing opacities. However, it has now been shown, as occurs …

Targeting The Apoa1 Locus For Liver-Directed Gene Therapy, Marco De Giorgi, Ang Li, Ayrea Hurley, Mercedes Barzi, Alexandria M Doerfler, Nikitha A Cherayil, Harrison E Smith, Jonathan D Brown, Charles Y Lin, Karl-Dimiter Bissig, Gang Bao, William R Lagor

Faculty, Staff and Students Publications

Clinical application of somatic genome editing requires therapeutics that are generalizable to a broad range of patients. Targeted insertion of promoterless transgenes can ensure that edits are permanent and broadly applicable while minimizing risks of off-target integration. In the liver, the Albumin (Alb) locus is currently the only well-characterized site for promoterless transgene insertion. Here, we target the Apoa1 locus with adeno-associated viral (AAV) delivery of CRISPR-Cas9 and achieve rates of 6% to 16% of targeted hepatocytes, with no evidence of toxicity. We further show that the endogenous Apoa1 promoter can drive robust and sustained expression of therapeutic …

Deciphering An Agrp-Serotoninergic Neural Circuit In Distinct Control Of Energy Metabolism From Feeding, Yong Han, Guobin Xia, Dollada Srisai, Fantao Meng, Yanlin He, Yali Ran, Yang He, Monica Farias, Giang Hoang, István Tóth, Marcelo O Dietrich, Miao-Hsueh Chen, Yong Xu, Qi Wu

Children’s Nutrition Research Center Staff Publications

Contrasting to the established role of the hypothalamic agouti-related protein (AgRP) neurons in feeding regulation, the neural circuit and signaling mechanisms by which they control energy expenditure remains unclear. Here, we report that energy expenditure is regulated by a subgroup of AgRP neurons that send non-collateral projections to neurons within the dorsal lateral part of dorsal raphe nucleus (dlDRN) expressing the melanocortin 4 receptor (MC4R), which in turn innervate nearby serotonergic (5-HT) neurons. Genetic manipulations reveal a bi-directional control of energy expenditure by this circuit without affecting food intake. Fiber photometry and electrophysiological results indicate that the thermo-sensing MC4RdlDRN neurons …

Liquid biopsy-based biomarkers, including circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA), are increasingly important for the characterization of metastatic breast cancer (MBC). The aim of the study was to explore CTCs and ctDNA dynamics to better understand their potentially complementary role in describing MBC.

METHODS: The study retrospectively analyzed 107 patients with MBC characterized with paired CTCs and ctDNA assessments and a second prospective cohort, which enrolled 48 patients with MBC. CTCs were immunomagnetically isolated and ctDNA was quantified and then characterized through next-generation sequencing in the retrospective cohort and droplet digital polymerase chain reaction in the prospective …

Rap1 In The Vmh Regulates Glucose Homeostasis, Kentaro Kaneko, Hsiao-Yun Lin, Yukiko Fu, Pradip K Saha, Ana B De La Puente-Gomez, Yong Xu, Kousaku Ohinata, Peter Chen, Alexei Morozov, Makoto Fukuda

Faculty, Staff and Students Publications

The hypothalamus is a critical regulator of glucose metabolism and is capable of correcting diabetes conditions independently of an effect on energy balance. The small GTPase Rap1 in the forebrain is implicated in high-fat diet-induced (HFD-induced) obesity and glucose imbalance. Here, we report that increasing Rap1 activity selectively in the medial hypothalamus elevated blood glucose without increasing the body weight of HFD-fed mice. In contrast, decreasing hypothalamic Rap1 activity protected mice from diet-induced hyperglycemia but did not prevent weight gain. The remarkable glycemic effect of Rap1 was reproduced when Rap1 was specifically deleted in steroidogenic factor-1-positive (SF-1-positive) neurons in the …

Patients' And Providers' Needs And Preferences When Considering Fertility Preservation Before Cancer Treatment: Decision-Making Needs Assessment, Aubri Hoffman, Laura Crocker, Aakrati Mathur, Deborah Holman, June Weston, Sukhkamal Campbell, Ashley Housten, Andrea Bradford, Shilpi Agrawala, Terri L Woodard

Faculty, Staff and Students Publications

BACKGROUND: As cancer treatments continue to improve, it is increasingly important that women of reproductive age have an opportunity to decide whether they want to undergo fertility preservation treatments to try to protect their ability to have a child after cancer. Clinical practice guidelines recommend that providers offer fertility counseling to all young women with cancer; however, as few as 12% of women recall discussing fertility preservation. The long-term goal of this program is to develop an interactive web-based patient decision aid to improve awareness, access, knowledge, and decision making for all young women with cancer. The International Patient Decision …

An Update On The Hiv Dna Vaccine Strategy, Joseph Hokello, Adhikarimayum Lakhikumar Sharma, Mudit Tyagi

Center for Translational Medicine Faculty Papers

In 2020, the global prevalence of human immunodeficiency virus (HIV) infection was estimated to be 38 million, and a total of 690,000 people died from acquired immunodeficiency syndrome (AIDS)–related complications. Notably, around 12.6 million people living with HIIV/AIDS did not have access to life-saving treatment. The advent of the highly active antiretroviral therapy (HAART) in the mid-1990s remarkably enhanced the life expectancy of people living with HIV/AIDS as a result of improved immune functions. However, HAART has several drawbacks, especially when it is not used properly, including a high risk for the development of drug resistance, as well as undesirable …

Evidence-Based Approach To Early Outpatient Treatment Of Sars-Cov-2 (Covid-19) Infection, J Drew Payne, Kimberly Sims, Cynthia Peacock, Tanis Welch, Ruth E Berggren

Faculty, Staff and Students Publications

Misinformation and promotion of well-intended but disproved therapies for COVID-19 have plagued evidence-based shared decision-making throughout the COVID-19 pandemic. In times of crisis, clinicians may feel that their strong inclination to prescribe potentially harmful, unproven therapies on behalf of their patients is supported by beneficence. Clinicians should mindfully identify and avoid commission bias during this pandemic, especially as more data have accumulated to assist with clinically sound decision-making. We describe a more evidence-based approach to treatment of early outpatient COVID-19, stressing the availability of Food and Drug Administration emergency use authorization therapies and considering plausibly beneficial, nonprescription supplements that are …

The Roles Of Tumor-Derived Exosomes In Altered Differentiation, Maturation And Function Of Dendritic Cells, Reza Hosseini, Leila Asef-Kabiri, Hassan Yousefi, Hamzeh Sarvnaz, Majid Salehi, Mohammad Esmaeil Akbari, Nahid Eskandari

School of Graduate Studies Faculty Publications

Tumor-derived exosomes (TDEs) have been shown to impede anti-tumor immune responses via their immunosuppressive cargo. Since dendritic cells (DCs) are the key mediators of priming and maintenance of T cell-mediated responses; thus it is logical that the exosomes released by tumor cells can exert a dominant influence on DCs biology. This paper intends to provide a mechanistic insight into the TDEs-mediated DCs abnormalities in the tumor context. More importantly, we discuss extensively how tumor exosomes induce subversion of DCs differentiation, maturation and function in separate sections. We also briefly describe the importance of TDEs at therapeutic level to help guide …

Gene Expression Analysis Of Environmental Temperature And High-Fat Diet-Induced Changes In Mouse Supraclavicular Brown Adipose Tissue, Yufeng Shi, Honglei Zhai, Sharon John, Yi-Ting Shen, Yali Ran, Giang Hoang, Miao-Hsueh Chen

Children’s Nutrition Research Center Staff Publications

Obesity, a dysregulation of adipose tissue, is a major health risk factor associated with many diseases. Brown adipose tissue (BAT)-mediated thermogenesis can potentially regulate energy expenditure, making it an attractive therapeutic target to combat obesity. Here, we characterize the effects of cold exposure, thermoneutrality, and high-fat diet (HFD) feeding on mouse supraclavicular BAT (scBAT) morphology and BAT-associated gene expression compared to other adipose depots, including the interscapular BAT (iBAT). scBAT was as sensitive to cold induced thermogenesis as iBAT and showed reduced thermogenic effect under thermoneutrality. While both scBAT and iBAT are sensitive to cold, the expression of genes involved …
