The Place Of Arbs In Heart Failure Therapy: Is Aldosterone Suppression The Key?, Uma Markan, Samhitha Pasupuleti, Celina M. Pollard, Arianna Perez Bhs Student, Beatrix Aukszi, Anastasios Lymperopoulos

Chemistry and Physics Faculty Articles

Since the launch of the first orally available angiotensin II (AngII) type 1 receptor (AT₁R) blocker (ARB) losartan (Cozaar) in the late 1990s, the class of ARBs (or ‘sartans’, short for Angiotensin-RecepTor-ANtagonistS) quickly expanded to include candesartan, eprosartan, irbesartan, valsartan, telmisartan, and olmesartan. All ARBs have high affinity for the AT₁ receptor, expressed in various tissues, including smooth muscle cells, heart, kidney, and brain. Since activation of AT₁R, the target of these drugs, leads, among other effects, to vascular smooth muscle cell growth, proliferation and contraction, activation of fibroblasts, cardiac hypertrophy, aldosterone secretion from the …

Estradiol Modulation Of The Renin-Angiotensin System And The Regulation Of Fear Extinction, Jenna N Parrish, Megan L Bertholomey, Hong W Pang, Robert Charles Speth, Mary M Torregrossa

Faculty Articles

Post-traumatic stress disorder (PTSD) is more prevalent in women than men, yet much remains to be determined regarding the mechanism underlying this sex difference. Clinical and preclinical studies have shown that low estradiol levels during extinction of fear conditioning in rodents (i.e., cue exposure therapy in humans) leads to poor extinction consolidation and increased fear during extinction recall. The renin-angiotensin system (RAS) is also associated with stress-related pathologies, and RAS antagonists can enhance extinction consolidation in males. However, less is known about how estradiol and the RAS converge to alter fear extinction consolidation in females. Since estradiol downregulates the RAS, …

Developing A Biased Unmatched Bivalent Ligand (Bumbl) Design Strategy To Target The Gpcr Homodimer Allosteric Signaling (Camp Over Β-Arrestin 2 Recruitment) Within The Melanocortin Receptors., Cody J Lensing, Katie T Freeman, Sathya M Schnell, Robert Charles Speth, Adam T Zarth, Carrie Haskell-Luevano

Faculty Articles

Understanding the functional relevance of G protein-coupled receptor (GPCR) homodimerization has been limited by the insufficient tools to assess asymmetric signaling occurring within dimers comprised of the same receptor type. We present unmatched bivalent ligands (UmBLs) to study the asymmetric function of melanocortin homodimers. UmBLs contain one agonist and one antagonist pharmacophore designed to target a melanocortin homodimer such that one receptor is occupied by an agonist and the other receptor by an antagonist pharmacophore. First-in-class biased UmBLs (BUmBLs) targeting the human melanocortin-4 receptor (hMC4R) were discovered. The BUmBLs displayed biased agonism by potently stimulating cAMP signaling (EC

Protective Actions Of Oxytocin On Aortic Wistar And Shr Vsmcs, Varun Kumar Soti

Student Theses, Dissertations and Capstones

Background. Oxytocin, known as a female reproductive hormone, has emerged as a cardiovascular hormone showing cardioprotective effects, for instance, negative chronotropic and inotropic effects and ANP release in cardiomyocytes and endothelium. However, oxytocin’s effect in VSMCs remains to be explored. Objectives. This study had three goals: characterizing oxytocin’s effect on proliferation, inflammation, oxidative stress, and vasocontraction pathway in Wistar VSMCs; determining oxytocin’s effect on Ang II; describing oxytocin’s effect and its interaction with Ang II in SHR VSMCs. Methods: Aortic VSMCs were isolated from Wistar rats and SHRs. Hemocytometer, MTT and 3H-Thymidine incorporation assays, and flow cytometry were employed for …

Enhancing The Sublingual Permeability Of Atropine Sulfate: Effect Of Ph And Penetration Enhancers, Rawan Saeed Bafail

Student Theses, Dissertations and Capstones

Atropine Sulfate (AS) auto-injector (AtroPen®) is being used as an effective and safe antidote for the treatment of organophosphate (OP) pesticides or nerve gas poisoning. The use of AtroPen® is associated with several drawbacks including: bulky size, availability, affordability, invasiveness, and administration errors. Previously, AS fast disintegrating sublingual tablets (FDSTs) were developed and the feasibility of AS sublingual permeability were demonstrated. However, AS permeability was delayed due to the negative impact of higher doses of AS on FDST’s physical characteristics. Therefore, the aim in this research project was to optimize the previously developed AS FDSTs. It was hypothesized that optimizing …

Medication Exposure Patterns In Primary Care Patients Prescribed Pharmacogenetically Actionable Opioids, Mitchell R. Knisely, Janet S. Carpenter, Marion E. Broome, Ann M. Holmes, Diane Von Ah, Todd Skaar, Claire Burke Draucker

The Qualitative Report

Current approaches to assessing medication exposure fail to capture the complexity of the phenomenon and the context in which it occurs. This study’s purpose was to develop a typology of subgroups of patients who share common patterns of medication exposure. To create the typology, we used an exemplar sample of 30 patients in a large public healthcare system who had been prescribed the pharmacogenetically actionable opioids codeine or tramadol. Data related to medication exposure were drawn from large data repositories. Using a person-oriented qualitative approach, eight subgroups of patients who shared common patterns of medication exposure were identified. The subgroups …

Human Β-Defensin 1 And Β-Defensin 3 (Mouse Ortholog Mbd14) Function As Full Endogenous Agonists At Select Melanocortin Receptors, Mark D. Ericson, Anamika Singh, Srinivasa R. Tala, Erica M. Haslach, Marvin L. Dirain, Jay W. Schaub, Viktor Flores, Natalie Eick, Cody J. Lensing, Katie T. Freeman, Branden A. Smeester, Danielle N. Adank, Stacey L. Wilber, Robert Speth, Carrie Haskell-Luevano

HPD Articles

β-Defensin 3 (BD3) was identified as a ligand for the melanocortin receptors (MCRs) in 2007, although the pharmacology activity of BD3 has not been clearly elucidated. Herein, it is demonstrated that human BD3 and mouse BD3 are full micromolar agonists at the MCRs. Furthermore, mouse β-defensin 1 (BD1) and human BD1 are also MCR micromolar agonists. This work identifies BD1 as an endogenous MCR ligand and clarifies the controversial role of BD3 as a micromolar agonist.

Effect Of Chronic Intermittent Hypoxia On Angiotensin Ii Receptors In The Central Nervous System., Barbara J Morgan, Nicole Schrimpf, Morgan Rothman, Ann Mitzey, Mark S Brownfield, Robert Charles Speth, John M Dopp

Faculty Articles

Chronic intermittent hypoxia (CIH) increases basal sympathetic nervous system activity, augments chemoreflex-induced sympathoexcitation, and raises blood pressure. All effects are attenuated by systemic or intracerebroventricular administration of angiotensin II type 1 receptor (AT₁R) antagonists. This study aimed to quantify the effects of CIH on AT₁R- and AT₂R-like immunoreactivity in the rostroventrolateral medulla (RVLM) and paraventricular nucleus of the hypothalamus (PVN), central regions that are important components of the extended chemoreflex pathway. Eighteen Sprague-Dawley rats were exposed to intermittent hypoxia (F_IO₂ = 0.10, 1 min at 4-min intervals) for 10 hr/day for …

Ancestral Dependence On Breast Stemness And Nucleotide Excision Repair In Breast Cancer Stem Cells In Novel Human Model Systems, Omar Ibrahim

Student Theses, Dissertations and Capstones

Precocious puberty, measured by thelarche or menarche, is a well-established breast cancer risk factor. Using a unique and patented tissue engineering system we established cell lines from 48 primary cultures of normal breast tissue from reduction mammoplasties and used them as an in vitro model of thelarche, quantifying episphere formation and ductal differentiation. Differential ductal formation was observed based on ancestry. In light of African American (AA) precocious thelarche both in vivo and as we observed in vitro, we hypothesized that AA women would exhibit an increased proportion of breast stem cells, with greater potency for differentiation. Five AA cell …

Analysis Of Molecular Changes In 2 Types Of Non-Tumor Adjacent Breast Identified By Nucleotide Excision Repair In Early Stage Breast Cancer, Manasi Ramesh Pimpley

Student Theses, Dissertations and Capstones

NER plays an important role in remediating DNA damage. Latimer et al., have previously shown nucleotideexcision repair (NER) to be intrinsically deficient in stage I sporadic BC by function and gene expression. Previous work performed on 12 isogenically matched stage I tumors and non-tumor adjacent (NTA) samples identified 2 types of NTA tissue with regard to functional NER. One type that represented 75% ofthe samples, had lower NER capacity, similar to the tumor (Low: Low pair). The other type had high NER relative to the tumor (High: Low pair). Two isogenic NTA/tumor cell line pairs representing these 2 types ofNTA …

A Direct In Vivo Comparison Of The Melanocortin Monovalent Agonist Ac-His-Dphe-Arg-Trp-Nh2 Versus The Bivalent Agonist Ac-His-Dphe-Arg-Trp-Pedg20-His-Dphe-Arg-Trp-Nh2: A Bivalent Advantage, Cody J Lensing, Danielle N Adank, Stacey L Wilber, Katie T Freeman, Sathya M Schnell, Robert Charles Speth, Adam T Zarth, Carrie Haskell-Luevano

Faculty Articles

Bivalent ligands targeting putative melanocortin receptor dimers have been developed and characterized in vitro, however studies of their functional in vivo effects have been limited. The current report compares the effects of homobivalent ligand CJL-1-87, Ac-His-DPhe-Arg-Trp-PEDG20-His-DPhe-Arg-Trp-NH₂, to monovalent ligand CJL-1-14, Ac-His-DPhe-Arg-Trp-NH₂ on energy homeostasis in mice after central intracerebroventricular (ICV) administration into the lateral ventricle of the brain. Bivalent ligand CJL-1-87 had noteworthy advantages as an anti-obesity probe over CJL-1-14 in a fasting-refeeding in vivo paradigm. Treatment with CJL-1-87 significantly decreased food intake compared to CJL-1-14 or saline (50% less intake 2 to 8 hours after …

Loss Of Resistance To Angiotensin Ii-Induced Hypertension In The Jackson Laboratory Recombination-Activating Gene Null Mouse On The C57bl/6j Background, Hong Ji, Amrita V Pai, Crystal A West, Xie Wu, Robert Charles Speth, Kathryn Sandberg

Faculty Articles

Resistance to angiotensin II (Ang II)–induced hypertension in T-cell–deficient male mice with a targeted mutation in the recombination-activating gene-1 (Rag1) on the C57BL/6J background (B6.Rag1^−/−-M), which was reported by 5 independent laboratories including ours before 2015, has been lost. In mice purchased from Jackson Laboratory in 2015 and 2016, the time course and magnitude increase in mean arterial pressure induced by 2 weeks of Ang II infusion at 490 ng/kg per minute was identical between B6.Rag1^−/−-M and male wild-type littermates. Moreover, there were no differences in the time course or magnitude increase …

A Consensus Definitive Classification Of Scavenger Receptors And Their Roles In Health And Disease, Mercy R Prabhudas, Cynthia L Baldwin, Paul L Bollyky, Dawn M E Bowdish, Kurt Drickamer, Maria Febbraio, Joachim Herz, Lester Kobzik, Monty Krieger, John Loike, Benita Mcvicker, Terry K Means, Soren K Moestrup, Steven R Post, Tatsuya Sawamura, Samuel Silverstein, Robert Charles Speth, Janice C Telfer, Geoffrey M Thiele, Xiang-Yang Wang, Samuel D Wright, Joseph El Khoury

Faculty Articles

Scavenger receptors constitute a large family of proteins that are structurally diverse and participate in a wide range of biological functions. These receptors are expressed predominantly by myeloid cells and recognize a diverse variety of ligands including endogenous and modified host-derived molecules and microbial pathogens. There are currently eight classes of scavenger receptors, many of which have multiple names, leading to inconsistencies and confusion in the literature. To address this problem, a workshop was organized by the United States National Institute of Allergy and Infectious Diseases, National Institutes of Health, to help develop a clear definition of scavenger receptors and …
