Complete Versus Culprit Only Revascularization In St-Elevation Myocardial Infarction-A Perspective On Recent Trials And Recommendations, Gabriela Andries, Sahil Khera, Robert Timmermans, Wilbert Aronow

NYMC Faculty Publications

The presence of multivessel coronary artery disease (CAD) is strongly associated with higher 30-day mortality, reduced myocardial reperfusion success, reinfarction, and occurrence of major adverse cardiac events (MACE) at 1 year compared with single-vessel CAD. Despite higher morbidity and mortality in patients with ST-elevation myocardial infarction (STEMI) and coexistent multivessel CAD, major guidelines recommended against percutaneous coronary intervention (PCI) on non-culprit lesions at the time of primary PCI in patients with STEMI who are hemodynamically stable. The presence of multivessel CAD often poses a therapeutic dilemma for interventional cardiologists. A few larger scale randomized controlled trials (RCTs) and meta-analyses have …

Insula And Amygdala Resting-State Functional Connectivity Differentiate Bipolar From Unipolar Depression, E Ambrosi, D B Arciniegas, A Madan, K N Curtis, M A Patriquin, R E Jorge, G Spalletta, J C Fowler, B C Frueh, R Salas

Staff and Researcher Publications

Objective: Distinguishing depressive episodes due to bipolar disorder (BD) or major depressive disorder (MDD) solely on clinical grounds is challenging. We aimed at comparing resting-state functional connectivity (rsFC) of regions subserving emotional regulation in similarly depressed BD and MDD.

Method: We enrolled 76 in-patients (BD, n = 36; MDD, n = 40) and 40 healthy controls (HC). A seed-based approach was used to identify regions showing different rsFC with the insula and the amygdala. Insular and amygdalar parcellations were then performed along with diagnostic accuracy of the main findings.

Results: Lower rsFC between the left insula and the left mid-dorsolateral …

Alternative Splicing Promotes Tumour Aggressiveness And Drug Resistance In African American Prostate Cancer., Bi-Dar Wang, Kristin Ceniccola, Sujin Hwang, Ramez Andrawis, Anelia Horvath, Jennifer A Freedman, Jacqueline Olender, Stefan Knapp, Travers Ching, Lana Garmire, Vyomesh Patel, Mariano A Garcia-Blanco, Steven R Patierno, Norman H Lee

Pharmacology and Physiology Faculty Publications

linical challenges exist in reducing prostate cancer (PCa) disparities. The RNA splicing landscape of PCa across racial populations has not been fully explored as a potential molecular mechanism contributing to race-related tumour aggressiveness. Here, we identify novel genome-wide, race-specific RNA splicing events as critical drivers of PCa aggressiveness and therapeutic resistance in African American (AA) men. AA-enriched splice variants of PIK3CD, FGFR3, TSC2 and RASGRP2 contribute to greater oncogenic potential compared with corresponding European American (EA)-expressing variants. Ectopic overexpression of the newly cloned AA-enriched variant, PIK3CD-S, in EA PCa cell lines enhances AKT/mTOR signalling and increases proliferative …

Abnormal Dendritic Maturation Of Developing Cortical Neurons Exposed To Corticotropin Releasing Hormone (Crh): Insights Into Effects Of Prenatal Adversity?, Megan M. Curran, Curt A. Sandman, Elysia Poggi Davis, Laura M. Glynn, Tallie Z. Baram

Psychology: Faculty Scholarship

Corticotropin releasing hormone (CRH) produced by the hypothalamus initiates the hypothalamic-pituitary-adrenal (HPA) axis, which regulates the body’s stress response. CRH levels typically are undetectable in human plasma, but during pregnancy the primate placenta synthesizes and releases large amounts of CRH into both maternal and fetal circulations. Notably, placental CRH synthesis increases in response to maternal stress signals. There is evidence that human fetal exposure to high concentrations of placental CRH is associated with behavioral consequences during infancy and into childhood, however the direct effects on of the peptide on the human brain are unknown. In this study, we used a …

Efficient Synthesis Of Cn2097 Using In Situ Activation Of Sulfhydryl Group, Shaban Darwish, Keykavous Parang, John Marshall, Dennis J. Goebel, Rakesh Tiwari

Pharmacy Faculty Articles and Research

CN2097 (R₇Cs-sCYK[KTE(β-Ala)]V) is a rationally designed peptidomimetic that shows effectiveness in preclinical models for the treatment of neurological disorders, such as Angelman syndrome, traumatic brain injury (TBI), and stroke. Because of its potential therapeutic activity for the treatment of human CNS disorders, there was an urgent need to develop an efficient strategy for large-scale synthesis of CN2097. The synthesis of CN2097 was accomplished using Fmoc/tBu solid phase chemistry in multiple steps. Two different peptide fragments (activated polyarginine peptide Npys-sCR₇ and CYK[KTE(β-Ala)]V) were synthesized, followed by solution phase coupling in water. Activation of the polyarginine (CR₇) …

Anxiety Associated Increased Cpg Methylation In The Promoter Of Asb1: A Translational Approach Evidenced By Epidemiological And Clinical Studies And A Murine Model, Rebecca T. Emeny, Jens Baumert, Anthony S. Zannas, Sonja Kunze, Simone Wahl, Stella Iurato

Dartmouth Scholarship

Epigenetic regulation in anxiety is suggested, but evidence from large studies is needed. We conducted an epigenome-wide association study (EWAS) on anxiety in a population-based cohort and validated our finding in a clinical cohort as well as a murine model. In the KORA cohort, participants (n= 1522, age 32–72 years) were administered the Generalized Anxiety Disorder (GAD-7) instrument, whole blood DNA methylation was measured (Illumina 450K BeadChip), and circulating levels of hs-CRP and IL-18 were assessed in the association between anxiety and methylation. DNA methylation was measured using the same instrument in a study of patients with anxiety disorders recruited …

Chemical Modulation Of Cancer Cells To Enhance Tumor Immunity, Florisela Herrejon Chavez

PSU McNair Scholars Online Journal

Breakthroughs in immunotherapy have led to cancer therapeutics that activate the immune system by blocking inhibitory mechanisms. This class of therapeutics has resulted in longer survival rates for cancer patients, some living over 10 years after being diagnosed as terminally ill. However, only a small fraction of patients who receive immunotherapy drugs respond favorably.Recent studies suggest that certain anticancer agents (both cytotoxic chemotherapeutics and targeted drugs) stimulate immune recognition of cancers. Identification of such immunomodulatory anticancer agents would make ideal partners for current immunotherapy treatments, thus increasing the proportion of the treated patients who benefit from immunotherapy. This study aimed …

The Motor Cortical Representation Of A Muscle Is Not Homogeneous In Brain Connectivity, Jo Armour Smith, Alaa Albishi, Sarine Babikian, Skulpan Asavasopon, Beth E. Fisher, Jason Kutch

Physical Therapy Faculty Articles and Research

Functional connectivity patterns of the motor cortical representational area of single muscles have not been extensively mapped in humans, particularly for the axial musculature. Functional connectivity may provide a neural substrate for adaptation of muscle activity in axial muscles that have both voluntary and postural functions. The purpose of this study was to combine brain stimulation and neuroimaging to both map the cortical representation of the external oblique (EO) in primary motor cortex (M1) and supplementary motor area (SMA), and to establish the resting-state functional connectivity associated with this representation. Motor evoked potentials were elicited from the EO muscle in …

Presynaptic Lrp4 Promotes Synapse Number And Function Of Excitatory Cns Neurons., Timothy J. Mosca, David J. Luginbuhl, Irving E. Wang, Liqun Luo

Department of Neuroscience Faculty Papers

Precise coordination of synaptic connections ensures proper information flow within circuits. The activity of presynaptic organizing molecules signaling to downstream pathways is essential for such coordination, though such entities remain incompletely known. We show that LRP4, a conserved transmembrane protein known for its postsynaptic roles, functions presynaptically as an organizing molecule. In the Drosophila brain, LRP4 localizes to the nerve terminals at or near active zones. Loss of presynaptic LRP4 reduces excitatory (not inhibitory) synapse number, impairs active zone architecture, and abolishes olfactory attraction - the latter of which can be suppressed by reducing presynaptic GABAB receptors. LRP4 overexpression increases …

Selective Inhibition Of Small-Diameter Axons Using Infrared Light, Emilie H. Lothet, Kendrick M. Shaw, Hui Lu, Junqi Zhuo, Yves T. Wang, Shi Gu, Hillel J. Chiel, Michael W. Jenkins

Faculty Scholarship

Novel clinical treatments to target peripheral nerves are being developed which primarily use electrical current. Recently, infrared (IR) light was shown to inhibit peripheral nerves with high spatial and temporal specificity. Here, for the first time, we demonstrate that IR can selectively and reversibly inhibit small-diameter axons at lower radiant exposures than large-diameter axons. We provide a mathematical rationale, and then demonstrate it experimentally in individual axons of identified neurons in the marine mollusk Aplysia californica, and in axons within the vagus nerve of a mammal, the musk shrew Suncus murinus. The ability to selectively, rapidly, and reversibly control small-diameter …

Integration Of Metabolomics, Transcriptomics, And Microrna Expression Profiling Reveals A Mir-143-Hk2-Glucose Network Underlying Zinc-Deficiency-Associated Esophageal Neoplasia, Louise Y. Fong, Ruiyan Jing, Karl Smalley, Cristian Taccioli, Johannes Fahrmann, Dinesh K. Barupal, Hansjuerg Alder, John L. Farber, Oliver Fiehn, Carlo M. Croce

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Esophageal squamous cell carcinoma (ESCC) in humans is a deadly disease associated with dietary zinc (Zn)-deficiency. In the rat esophagus, Zn-deficiency induces cell proliferation, alters mRNA and microRNA gene expression, and promotes ESCC. We investigated whether Zn-deficiency alters cell metabolism by evaluating metabolomic profiles of esophageal epithelia from Zn-deficient and replenished rats vs sufficient rats, using untargeted gas chromatography time-of-flight mass spectrometry (n = 8/group). The Zn-deficient proliferative esophagus exhibits a distinct metabolic profile with glucose down 153-fold and lactic acid up 1.7-fold (P < 0.0001), indicating aerobic glycolysis (the "Warburg effect"), a hallmark of cancer cells. Zn-replenishment rapidly increases glucose content, restores deregulated metabolites to control levels, and reverses the hyperplastic phenotype. Integration of metabolomics and our reported transcriptomic data for this tissue unveils a link between glucose down-regulation and overexpression of HK2, an enzyme that catalyzes the first step of glycolysis and is overexpressed in cancer cells. Searching our published microRNA profile, we find that the tumor-suppressor miR-143, a negative regulator of HK2, is down-regulated in Zn-deficient esophagus. Using in situ hybridization and immunohistochemical analysis, the inverse correlation between miR-143 down-regulation and HK2 overexpression is documented in hyperplastic Zndeficient esophagus, archived ESCC-bearing Zn-deficient esophagus, and human ESCC tissues. Thus, to sustain uncontrolled cell proliferation, Zn-deficiency reprograms glucose metabolism by modulating expression of miR-143 and its target HK2. Our work provides new insight into critical roles of Zn in ESCC development and prevention. © Fong et al.

Exploring Cancer Metabolism Using Stable Isotope-Resolved Metabolomics (Sirm), Ronald C. Bruntz, Andrew N. Lane, Richard M. Higashi, Teresa W. -M. Fan

Center for Environmental and Systems Biochemistry Faculty Publications

Metabolic reprogramming is a hallmark of cancer. The changes in metabolism are adaptive to permit proliferation, survival, and eventually metastasis in a harsh environment. Stable isotope-resolved metabolomics (SIRM) is an approach that uses advanced approaches of NMR and mass spectrometry to analyze the fate of individual atoms from stable isotope-enriched precursors to products to deduce metabolic pathways and networks. The approach can be applied to a wide range of biological systems, including human subjects. This review focuses on the applications of SIRM to cancer metabolism and its use in understanding drug actions.

Signalling Via The Osteopontin And High Mobility Group Box-1 Axis Drives The Fibrogenic Response To Liver Injury, Elena Arriazu, Xiaodong Ge, Tung-Ming Leung, Fernando Magdaleno, Aritz Lopategi, Yongke Lu, Naoto Kitamura, Raquel Urtasun, Neil Theise, Daniel J. Antoine, Natalia Nieto

Pharmacology, Physiology and Toxicology

Objective: Liver fibrosis is associated with significant collagen-I deposition largely produced by activated hepatic stellate cells (HSCs); yet, the link between hepatocyte damage and the HSC profibrogenic response remains unclear. Here we show significant induction of osteopontin (OPN) and high-mobility group box-1 (HMGB1) in liver fibrosis. Since OPN was identified as upstream of HMGB1, we hypothesised that OPN could participate in the pathogenesis of liver fibrosis by increasing HMGB1 to upregulate collagen-I expression. Design and results: Patients with long-term hepatitis C virus (HCV) progressing in disease stage displayed enhanced hepatic OPN and HMGB1 immunostaining, which correlated with fibrosis stage, whereas …

The Trial Lawyer And The Reptilian Brain: A Critique, Louis J. Sirico, Jr.

Cleveland State Law Review

This Article brings together neuroscience, cultural symbolism, and the strategies of practicing lawyers to critique the reptile strategy, now popular among trial lawyers. The strategy directs the lawyer to trigger the reptilian brains of jurors so that they react instinctively to threats to themselves and their communities. When humans feel threatened, the reptilian brain, the most primitive part of the brain, takes charge and instinctively controls human conduct. Therefore, if a lawyer can make a juror feel threatened, the lawyer makes an appeal to the juror’s reptilian brain and virtually assures a victory. Thus, a lawyer’s argument should intensify the …

Microbiology, Immunology, and Molecular Genetics Faculty Publications

A number of bacterial pathogens require the ZnuABC Zinc (Zn²⁺) transporter and/or a second Zn²⁺ transport system to overcome Zn²⁺ sequestration by mammalian hosts. Previously we have shown that in addition to ZnuABC, Yersinia pestis possesses a second Zn²⁺ transporter that involves components of the yersiniabactin (Ybt), siderophore-dependent iron transport system. Synthesis of the Ybt siderophore and YbtX, a member of the major facilitator superfamily, are both critical components of the second Zn²⁺ transport system. Here we demonstrate that a ybtX znu double mutant is essentially avirulent in mouse models of bubonic and pneumonic …

Source Localization Of Brain States Associated With Canonical Neuroimaging Postures, Michael Lifshitz, Robert T. Thibault, Raquel R. Roth, Amir Raz

Psychology Faculty Articles and Research

Cognitive neuroscientists rarely consider the influence that body position exerts on brain activity; yet, postural variation holds important implications for the acquisition and interpretation of neuroimaging data. Whereas participants in most behavioral and EEG experiments sit upright, many prominent brain imaging techniques (e.g., fMRI) require participants to lie supine. Here we demonstrate that physical comportment profoundly alters baseline brain activity as measured by magnetoencephalography (MEG)—an imaging modality that permits multipostural acquisition. We collected resting-state MEG data from 12 healthy participants in three postures (lying supine, reclining at 45°, and sitting upright). Source-modeling analysis revealed a broadly distributed influence of posture …

The 11s Proteasomal Activator Regγ Impacts Polyglutamine-Expanded Androgen Receptor Aggregation And Motor Neuron Viability Through Distinct Mechanisms., Jill M. Yersak, Heather L. Montie, Erica S. Chevalier-Larsen, Yuhong Liu, Lan Huang, Martin Rechsteiner, Diane E. Merry

Department of Biochemistry and Molecular Biology Faculty Papers

Spinal and bulbar muscular atrophy (SBMA) is caused by expression of a polyglutamine (polyQ)-expanded androgen receptor (AR). The inefficient nuclear proteasomal degradation of the mutant AR results in the formation of nuclear inclusions containing amino-terminal fragments of the mutant AR. PA28γ (also referred to as REGγ) is a nuclear 11S-proteasomal activator with limited proteasome activation capabilities compared to its cytoplasmic 11S (PA28α, PA28β) counterparts. To clarify the role of REGγ in polyQ-expanded AR metabolism, we carried out genetic and biochemical studies in cell models of SBMA. Overexpression of REGγ in a PC12 cell model of SBMA increased polyQ-expanded AR aggregation …

Easi-Crispr: A Robust Method For One-Step Generation Of Mice Carrying Conditional And Insertion Alleles Using Long Ssdna Donors And Crispr Ribonucleoproteins., Rolen M Quadros, Hiromi Miura, Donald W Harms, Hisako Akatsuka, Takehito Sato, Tomomi Aida, Ronald Redder, Guy P Richardson, Yutaka Inagaki, Daisuke Sakai, Shannon M Buckley, Parthasarathy Seshacharyulu, Surinder K Batra, Mark A Behlke, Sarah A Zeiner, Ashley M Jacobi, Yayoi Izu, Wallace B Thoreson, Lisa D Urness, Suzanne L Mansour, Masato Ohtsuka, Channabasavaiah B Gurumurthy

Journal Articles: Munroe-Meyer Institute

BACKGROUND: Conditional knockout mice and transgenic mice expressing recombinases, reporters, and inducible transcriptional activators are key for many genetic studies and comprise over 90% of mouse models created. Conditional knockout mice are generated using labor-intensive methods of homologous recombination in embryonic stem cells and are available for only ~25% of all mouse genes. Transgenic mice generated by random genomic insertion approaches pose problems of unreliable expression, and thus there is a need for targeted-insertion models. Although CRISPR-based strategies were reported to create conditional and targeted-insertion alleles via one-step delivery of targeting components directly to zygotes, these strategies are quite inefficient. …

Identification Of Octopaminergic Neurons That Modulate Sleep Suppression By Male Sex Drive., Daniel R. Machado, Dinis Afonso, Alexandra R. Kenny, Arzu Öztürk-Çolak, Emilia H. Moscato, Benjamin Mainwaring, Matthew Kayser, Kyunghee Koh

Department of Neuroscience Faculty Papers

Molecular and circuit mechanisms for balancing competing drives are not well understood. While circadian and homeostatic mechanisms generally ensure sufficient sleep at night, other pressing needs can overcome sleep drive. Here, we demonstrate that the balance between sleep and sex drives determines whether male flies sleep or court, and identify a subset of octopaminergic neurons (MS1) that regulate sleep specifically in males. When MS1 neurons are activated, isolated males sleep less, and when MS1 neurons are silenced, the normal male sleep suppression in female presence is attenuated and mating behavior is impaired. MS1 neurons do not express the sexually dimorphic …

Markey Cancer Center Faculty Publications

Thermotherapy, as a method of treating cancer, has recently attracted considerable attention from basic and clinical investigators. A number of studies and clinical trials have shown that thermotherapy can be successfully used as a therapeutic approach for various cancers. However, the effects of temperature on cancer bioenergetics have not been studied in detail with a real time, in a microplate, label-free detection approach.

This study investigate how changes in temperature affect the bioenergetics characteristics (mitochondrial function and glycolysis) of three colorectal cancer (CRC) cell lines utilizing the Seahorse XF96 technology. Experiments were performed at 32°C, 37°C and 42°C using assay …

Faculty Works

Leukemia is cancer of the blood and bone marrow, it is the most common cancer found in children and is found to be more than one fourth of pediatric cancers. It causes white blood cells to become abnormal and the body to become weak. This deficiency in the immune system reduces the body's ability to fight infection or simple airborne illnesses, causing extensive treatment of common pathogens and cancer treatment. The present review covers all topics, from diagnosis to treatment of pediatric leukemia, as well as the stages of growth and physiological changes throughout the process. As leukemia has a …
