Purification And Use Of Trna For Enzymatic Post-Translational Addition Of Amino Acids To Proteins., Irem Avcilar-Kucukgoze, Howard Gamper, Ya-Ming Hou, Anna Kashina

Department of Biochemistry and Molecular Biology Faculty Papers

Post-translational addition of amino acids to proteins by enzymes using aminoacyl-tRNA is an emerging regulatory mechanism. Examples include Arg transfer in eukaryotes, Leu/Phe transfer in bacteria, and tRNA-synthetase-mediated addition of amino acids to Lys side chains. Here, we present a method of purification and use of tRNA for such reactions, focusing on tRNA^Arg and its use for arginylation. This method can also be used for other tRNA-mediated reactions. For complete details on the use and execution of this protocol, please refer to Avcilar-Kucukgoze et al. (2020).

Progressive remodeling of the heart, resulting in cardiomyocyte (CM) loss and increased inflammation, fibrosis, and a progressive decrease in cardiac function, are hallmarks of myocardial infarction (MI)-induced heart failure. We show that MCB-613, a potent small molecule stimulator of steroid receptor coactivators (SRCs) attenuates pathological remodeling post-MI. MCB-613 decreases infarct size, apoptosis, hypertrophy, and fibrosis while maintaining significant cardiac function. MCB-613, when given within hours post MI, induces lasting protection from adverse remodeling concomitant with: 1) inhibition of macrophage inflammatory signaling and interleukin 1 (IL-1) signaling, which attenuates the acute inflammatory response, 2) attenuation of fibroblast differentiation, and 3) promotion …

Pandemic Vibrio Cholerae Shuts Down Site-Specific Recombination To Retain An Interbacterial Defence Mechanism, Francis J. Santoriello, Lina Michel, Daniel Unterweger, Stefan Pukatzki

Publications and Research

Vibrio cholerae is an aquatic microbe that can be divided into three subtypes: harmless environmental strains, localised pathogenic strains, and pandemic strains causing global cholera outbreaks. Each type has a contact-dependent type VI secretion system (T6SS) that kills neighbouring competitors by translocating unique toxic effector proteins. Pandemic isolates possess identical effectors, indicating that T6SS effectors may affect pandemicity. Here, we show that one of the T6SS gene clusters (Aux3) exists in two states: a mobile, prophage-like element in a small subset of environmental strains, and a truncated Aux3 unique to and conserved in pandemic isolates. Environmental Aux3 can be readily …

Immune Phenotype Of Patients With Stage Iv Metastatic Inflammatory Breast Cancer., Sandra V Fernandez, Alexander W Macfarlane, Mowafaq Jillab, Maria F Arisi, Jennifer Yearley, Lakshmanan Annamalai, Yulan Gong, Kathy Q Cai, R Katherine Alpaugh, Massimo Cristofanilli, Kerry S Campbell

Student Papers, Posters & Projects

BACKGROUND: Inflammatory breast cancer (IBC) is a rare but aggressive carcinoma characterized by severe erythema and edema of the breast, with many patients presenting in advanced metastatic disease. The "inflammatory" nature is not due to classic immune-mediated inflammation, but instead results from tumor-mediated blockage of dermal lymphatic ducts. Previous work has shown that expression of PD-L1 on tumor cells can suppress T cell activation in triple-negative (TN) non-IBC breast cancer. In the present work, we investigated immune parameters in peripheral blood of metastatic IBC patients to determine whether cellular components of the immune system are altered, thereby contributing to pathogenesis …

Apneic Oxygenation: An Adjunctive Therapy For Laryngoscopy During Anesthesia Induction, Yaro Hoffman

Doctoral Projects

Endotracheal intubation is an essential component within the skill set of anesthesia providers. Rapid arterial desaturation remains a primary risk factor during laryngoscopy and intubation. The risk for hypoxemia exists because during endotracheal intubation, patients are apneic or hypo-ventilating (Wong et al., 2017). Apneic oxygenation (AO) has been advocated to attenuate hypoxemia during endotracheal intubation (Pavlov et al., 2017).

The aim of this project was to assess for any knowledge deficits regarding AO among anesthesia providers and assess the willingness of these providers to include AO into their current practice. The project investigator conducted an education session involving the …

Sleep Induction By Mechanosensory Stimulation In Drosophila., Arzu Öztürk-Çolak, Sho Inami, Joseph R. Buchler, Patrick D. Mcclanahan, Andri Cruz, Christopher Fang-Yen, Kyunghee Koh

Department of Neuroscience Faculty Papers

People tend to fall asleep when gently rocked or vibrated. Experimental studies have shown that rocking promotes sleep in humans and mice. However, the mechanisms underlying the phenomenon are not well understood. A habituation model proposes that habituation, a form of non-associative learning, mediates sleep induction by monotonous stimulation. Here, we show that gentle vibration promotes sleep in Drosophila in part through habituation. Vibration-induced sleep (VIS) leads to increased homeostatic sleep credit and reduced arousability, and can be suppressed by heightened arousal or reduced GABA signaling. Multiple mechanosensory organs mediate VIS, and the magnitude of VIS depends on vibration frequency …

Inferior St-Elevation Myocardial Infarction Presenting When Urgent Primary Percutaneous Coronary Intervention Is Unavailable: Should We Adhere To Current Guidelines?, Yochai Birnbaum, Glenn N Levine, John French, Juan Carlos Kaski, Dan Atar, Mahboob Alam, David Hasdai, Hani Jneid, Barry F Uretsky

Faculty, Staff and Students Publications

The pivotal studies that led to the recommendations for emergent reperfusion therapy for ST-elevation myocardial infarction (STEMI) were conducted for the most part over 25 years ago. At that time, contemporary standard treatments including aspirin, statin, and even anticoagulation were not commonly used. The 2013 American College of Cardiology Foundation (ACCF)/American Heart Association (AHA) guidelines and the 2017 European Society of Cardiology guidelines give a class I recommendation (with the level of evidence A) for primary percutaneous coronary intervention (pPCI) in patients with STEMI and ischemic symptoms of less than 12 h. However, if the patient presents to a hospital …

Advances in cancer treatments have improved clinical outcomes, leading to an increasing population of cancer survivors. However, this success is associated with high rates of short- and long-term cardiovascular (CV) toxicities. The number and variety of cancer drugs and CV toxicity types make long-term care a complex undertaking. This requires a multidisciplinary approach that includes expertise in oncology, cardiology and other related specialties, and has led to the development of the cardio-oncology subspecialty. This paper aims to provide an overview of the main adverse events, risk assessment and risk mitigation strategies, early diagnosis, medical and complementary strategies for prevention and …

Validation Of Novel Obstructive Sleep Apnea Treatment With Silicone Gel Experimental Models, Dustin Walter Burd

UNLV Theses, Dissertations, Professional Papers, and Capstones

Predictive modeling to increase treatment success rates for surgical procedures is becoming more common in the scientific community. For obstructive sleep apnea (OSA), modeling has been predominately performed using computers as opposed to experimental models. Computer simulation saves time by eliminating the need to fabricate complex experimental models but comes at the expense of insight gained through physical observations made in real time. Experimental models for studying OSA are needed to validate computational work, provide perspective on anatomical scale and demonstrate complex deformations in real time. This work addresses prior hurdles in experimental model fabrication with a novel process using …

Association Between White Matter Hyperintensities, Cortical Thinning, And Clinical Outcomes In Mild Traumatic Brain Injury, Thomas Helmut Knoblauch

UNLV Theses, Dissertations, Professional Papers, and Capstones

Traumatic Brain Injury (TBI) is a global health challenge, with over 4.6 million confirmed cases annually in North America alone. Mild traumatic brain injuries (mTBIs) are the most common and make up approximately 81% of all TBI diagnoses worldwide [1]. Studies indicate that 10–15% of patients suffer from trauma induced symptoms (i.e. headache, loss of balance, cognitive impairments, fatigue, and mental health/affective disorders) as far as 1 year post injury [2]. Prediction and management of these post-traumatic sequalae is complicated by a lack of symptom associated neuroimaging findings. In spite of a “prominent distribution” of frontotemporal WMHs in pediatric subjects …

Obesity fosters low-grade inflammation in white adipose tissue (WAT) that may contribute to the insulin resistance that characterizes type 2 diabetes. However, the causal relationship of these events remains unclear. The established dominance of STAT1 function in the immune response suggests an obligate link between inflammation and the comorbidities of obesity. To this end, we sought to determine how STAT1 activity in white adipocytes affects insulin sensitivity. STAT1 expression in WAT inversely correlated with fasting plasma glucose in both obese mice and humans. Metabolomic and gene expression profiling established STAT1 deletion in adipocytes (STAT1a-KO) enhanced mitochondrial function …

External Stoma Diversion: A Palliative Measure For Peristomal Wound Healing In Resource-Limited Settings, Rachel W Davis, Youmna A Sherif, Catherine Anne Morrison

Faculty, Staff and Students Publications

The provision of intestinal stoma care is challenging in austere settings due to limitations in surgical and wound care access as well as the high cost and sparsity of ostomy supplies. As a result, many surgical patients suffer from ostomy-related complications such as peristomal wounds and are unable to find relief for these complications from standard treatments and measures. This article describes the external stoma diversion, a cost-effective palliative surgical procedure that assists in the healing of peristomal wounds in resource-limited settings.

Postacute Covid-19: An Overview And Approach To Classification, Eva M Amenta, Amy Spallone, Maria C Rodriguez-Barradas, Hana M El Sahly, Robert L Atmar, Prathit A Kulkarni

Faculty, Staff and Students Publications

As the coronavirus disease 2019 (COVID-19) pandemic has progressed, a large volume of literature has developed delineating the clinical manifestations of acute infection. Recent reports have also started to describe persistent symptoms extending beyond the period of initial illness or hospitalization. Anecdotes of different signs and symptoms occurring after acute infection have also arisen in the lay press. Here we describe the current existing medical literature on the emerging concept of postacute COVID-19 and suggest an approach to classifying different manifestations of the syndrome. We also review long-term clinical manifestations observed in patients who recovered from infection due to other …

Autologous blood products, such as platelet-rich plasma (PRP) are commercial products broadly used to accelerate healing of tissues after injuries. However, their content is not standardized and significantly varies in composition, which may lead to differences in clinical efficacy. Also, the underlying molecular mechanisms for therapeutic effects are not well understood.

Purpose

A proteomic study was performed to compare the composition of low leukocyte PRP, platelet poor plasma (PPP), and blood plasma. Pathway analysis of the proteomic data was performed to evaluate differences between plasma formulations at the molecular level. Low abundance regulatory proteins in plasma were identified and …

Model For End-Stage Liver Disease-Sodium Underestimates 90-Day Mortality Risk In Patients With Acute-On-Chronic Liver Failure, Ruben Hernaez, Yan Liu, Jennifer R Kramer, Abbas Rana, Hashem B El-Serag, Fasiha Kanwal

Faculty, Staff and Students Publications

BACKGROUND & AIMS: It is unclear whether the model for end-stage liver disease-sodium (MELD-Na) score captures the clinical severity of acute-on-chronic liver failure (ACLF). We compared observed 90-day mortality in patients with ACLF with expected mortality based on the calculated MELD-Na and examined the consequences of underestimating clinical severity.

METHODS: We identified patients with ACLF during hospitalization for cirrhosis in 127 VA hospitals between 01/01/2004 and 12/31/2014. We examined MELD-Na scores by ACLF presence and grade. We used actual and observed 90-day mortality to estimate a standardized mortality ratio (SMR) by ACLF presence and grade. We used transplant center-specific median …

Mouse Models To Study The Pathophysiology Of Combined Methylmalonic Acidemia And Homocystinuria, Cblc Type, Tiffany Chern, Annita Achilleos, Xuefei Tong, Chih-Wei Hsu, Leeyean Wong, Ross A Poché

Faculty, Staff and Students Publications

Combined methylmalonic acidemia and homocystinuria, cblC type, is the most common inherited disorder of cobalamin metabolism and is characterized by severe fetal developmental defects primarily impacting the central nervous system, hematopoietic system, and heart. CblC was previously shown to be due to mutations in the MMACHC gene, which encodes a protein thought to function in intracellular cobalamin trafficking and biosynthesis of adenosylcobalamin (AdoCbl) and methylcobalamin (MeCbl). These coenzymes are required for the production of succinyl-CoA and methionine, respectively. However, it is currently unclear whether additional roles for MMACHC exist outside of cobalamin metabolism. Furthermore, due to a lack of sufficient …

Depletion Of Essential Isoprenoids And Er Stress Induction Following Acute Liver-Specific Deletion Of Hmg-Coa Reductase, Marco De Giorgi, Kelsey E Jarrett, Jason C Burton, Alexandria M Doerfler, Ayrea Hurley, Ang Li, Rachel H Hsu, Mia Furgurson, Kalyani R Patel, Jun Han, Christoph H Borchers, William R Lagor

Faculty, Staff and Students Publications

HMG-CoA reductase (Hmgcr) is the rate-limiting enzyme in the mevalonate pathway and is inhibited by statins. In addition to cholesterol, Hmgcr activity is also required for synthesizing nonsterol isoprenoids, such as dolichol, ubiquinone, and farnesylated and geranylgeranylated proteins. Here, we investigated the effects of Hmgcr inhibition on nonsterol isoprenoids in the liver. We have generated new genetic models to acutely delete genes in the mevalonate pathway in the liver using AAV-mediated delivery of Cre-recombinase (AAV-Cre) or CRISPR/Cas9 (AAV-CRISPR). The genetic deletion of Hmgcr by AAV-Cre resulted in extensive hepatocyte apoptosis and compensatory liver regeneration. At the biochemical …

Characterization Of Adiposity And Inflammation Genetic Pleiotropy Underlying Cardiovascular Risk Factors In Hispanics., Mohammad Yaser (Anwar)

Electronic Theses and Dissertations

The observed overlap between genetic variants associated with both adiposity and inflammatory markers suggests that changes in both adiposity and inflammation could be partially mediated by common pathways. The pervasive but sparsely characterized “pleiotropic” genetic variants associated with both adiposity and inflammation have been hypothesized to provide insight into the shared biology. This study explored and characterized the genetic pleiotropy underpinning adiposity and inflammation using genetic and phenotypic observations from the Cameron County Hispanic Cohort (CCHC). A total of 3,313 samples and >9 million single nucleotide polymorphisms (SNPs) were examined in this study. Mixed model genome-wide association studies (GWAS) were …

Role Of Metabolism In Bone Development And Homeostasis, Akiko Suzuki, Mina Minamide, Chihiro Iwaya, Kenichi Ogata, Junichi Iwata

Faculty, Staff and Student Publications

Carbohydrates, fats, and proteins are the underlying energy sources for animals and are catabolized through specific biochemical cascades involving numerous enzymes. The catabolites and metabolites in these metabolic pathways are crucial for many cellular functions; therefore, an imbalance and/or dysregulation of these pathways causes cellular dysfunction, resulting in various metabolic diseases. Bone, a highly mineralized organ that serves as a skeleton of the body, undergoes continuous active turnover, which is required for the maintenance of healthy bony components through the deposition and resorption of bone matrix and minerals. This highly coordinated event is regulated throughout life by bone cells such …

Differences In Gynecologic Tumor Development In Amhr2-Cre Mice With Krasg12d Or Krasg12v Mutations, Eucharist H S Kun, Yvonne T M Tsang, Sophia Lin, Sophia Pan, Tejas Medapalli, Anais Malpica, Joanne S Richards, David M Gershenson, Kwong-Kwok Wong

Faculty, Staff and Students Publications

How different KRAS variants impact tumor initiation and progression in vivo has not been thoroughly examined. We hypothesize that the ability of either KRASG12D or KRASG12V mutations to initiate tumor formation is context dependent. Amhr2-Cre mice express Cre recombinase in tissues that develop into the fallopian tubes, uterus, and ovaries. We used these mice to conditionally express either the KRASG12V/+ or KRASG12D/+ mutation. Mice with the genotype Amhr2-Cre Pten(fl/fl) KrasG12D/+(G12D mice) had abnormal follicle structures and developed low-grade serous ovarian carcinomas with 100% penetrance within 18 weeks. In contrast, mice with …

Security And Privacy When Applying Fair Principles To Genomic Information, Jaime Delgado, Silvia Llorente

Faculty, Staff and Student Publications

Making data Findable, Accessible, Interoperable and Reusable (FAIR) is a good approach when data needs to be shared. However, security and privacy are still critical aspects. In the FAIRification process, there is a need both for de-identification of data and for license attribution. The paper analyses some of the issues related to this process when the objective is sharing genomic information. The main results are the identification of the already existing standards that could be used for this purpose and how to combine them. Nevertheless, the area is quickly evolving and more specific standards could be specified.
