Localization And Distribution Of Primary Cilia In The Adult Mouse Heart, Ali Zarban, Hannah C. Saternos, Andrea L. Kalinoski, Lijun Liu, Surya M. Nauli, Wissam A. Aboualaiwi

Pharmacy Faculty Articles and Research

Although primary cilia have been shown to play crucial roles in the development of embryonic mouse heart, their presence and function in adult mouse heart remains controversial. In this study, the presence of primary cilia in adult mouse heart was investigated. The presence of primary cilia was initially demonstrated in the surface of cardiac cells of mouse hearts from both young and adult mice by immunostaining with acetylated α-tubulin, a ciliary structural marker. The presence of cardiac primary cilia in 1-, 3-, 6- and 12-month old mice was further confirmed by staining heart tissues with an antibody against pericentrin, a …

Patterns Of Fecal Progestagens, Estrogens, And Androgens Associated With Reproduction In Blue-Throated Piping Guans (Pipile Cumanensis), Leslie Ann Sterling, Helen Clawitter, Corinne P. Kozlowski, Michael Macek, Anne Tieber

Undergraduate Research Symposium Posters

While fecal hormone analyses are routinely employed to monitor reproduction in mammals, few studies have used these techniques for monitoring reproductive events in birds. This study describes the endocrine patterns associated with reproduction in the blue-throated piping guan (Pipile cumanensis), a less threatened relative of the critically endangered Trinidad piping guan (P. pipile). Fecal samples were collected approximately once a week for 3 years from seven female guans and six male guans at the Saint Louis Zoo. Concentrations of fecal progestagens, estrogens, and androgens were quantified using commercially available enzyme immunoassays. Baseline progestagen concentrations for females …

Optimization Of A Genomic Editing System Using Crispr/Cas9-Induced Site-Specific Gene Integration, Jillian L. Mccool Ms., Nick Hum, Gabriela G. Loots

STAR Program Research Presentations

The CRISPR-Cas system is an adaptive immune system found in bacteria which helps protect against the invasion of other microorganisms. This system induces double stranded breaks at precise genomic loci (1) in which repairs are initiated and insertions of a target are completed in the process. This mechanism can be used in eukaryotic cells in combination with sgRNAs (1) as a tool for genome editing. By using this CRISPR-Cas system, in addition to the “safe harbor locus,” ROSAβ26, the incorporation of a target gene into a site that is not susceptible to gene silencing effects can be achieved through few …

High-Sensitivity Mass Spectrometry For Probing Gene Translation In Single Embryonic Cells In The Early Frog (Xenopus) Embryo, Camille Lombard-Banek, Sally Ann Moody, Peter Nemes

Anatomy and Regenerative Biology Faculty Publications

Direct measurement of protein expression with single-cell resolution promises to deepen the understanding of basic molecular processes during normal and impaired development. High-resolution mass spectrometry provides detailed coverage of the proteomic composition of large numbers of cells. Here we discuss recent mass spectrometry developments based on single-cell capillary electrophoresis that extend discovery proteomics to sufficient sensitivity to enable the measurement of proteins in single cells. The single-cell mass spectrometry system is used to detect a large number of proteins in single embryonic cells in blastomeres in the 16-cell embryo of the South African clawed frog (Xenopus laevis) that give rise …

Genetic Analysis Reveals A Hierarchy Of Interactions Between Polycystin-Encoding Genes And Genes Controlling Cilia Function During Left-Right Determination, Daniel T. Grimes, Jennifer L. Keynton, Maria T. Buenavista, Xingjian Jin, Saloni H. Patel, Shinohara Kyosuke, Jennifer Vibert, Debbie J. Williams, Hiroshi Hamada, Rohana Hussain, Surya M. Nauli, Dominic P. Norris

Pharmacy Faculty Articles and Research

During mammalian development, left-right (L-R) asymmetry is established by a cilia-driven leftward fluid flow within a midline embryonic cavity called the node. This ‘nodal flow’ is detected by peripherally-located crown cells that each assemble a primary cilium which contain the putative Ca²⁺ channel PKD2. The interaction of flow and crown cell cilia promotes left side-specific expression of Nodal in the lateral plate mesoderm (LPM). Whilst the PKD2-interacting protein PKD1L1 has also been implicated in L-R patterning, the underlying mechanism by which flow is detected and the genetic relationship between Polycystin function and asymmetric gene expression remains unknown. Here, we …

Assessment Of Daf-19 Related Behavioral Defects, Loraina A. Stinson

Lawrence University Honors Projects

The daf-19 gene encodes the only RFX transcription factors in C. elegans, producing at least four related protein isoforms, one of which, DAF-19C, is responsible for ciliogenesis. Previous work by Senti and Swoboda (2008) demonstrated that adult worms deficient in all four DAF-19 proteins have extremely aberrant dwelling and roaming behavior on bacterial food. Most intriguingly, the addition of cDNA encoding the DAF-19C isoform restores cilia formation, but does not fully restore wild-type dwelling and roaming behavior. We are suggesting that additional neuron functions are needed to properly execute behaviors and these neuron functions require the activity of other …

Programming Heart Disease: Does Poor Maternal Nutrition Alter Expression Of Cardiac Markers Of Proliferation, Hypertrophy, And Fibrosis In Offspring?, Cathy Chun

Honors Scholar Theses

Maternal malnutrition can affect fetal organogenesis, metabolic processes, and factors involved in developmental regulation. Of the many physiological effects poor maternal nutrition can induce in offspring, one of the most important organs affected is the heart. Cardiovascular disease has been associated with poor maternal diet. It also been suggested that hypertension can originate during impaired intrauterine growth and development. Hypertension can trigger hypertensive heart disease and is associated with numerous heart complications. We hypothesized that poor maternal nutrition would alter critical growth factors associated with normal heart development, specifically, insulin-like growth factor (IGF)-1, IGF-2, transforming growth factor (TGF)β, and connective …

The Roles Of Malt1 In Nf-Κb Activation And Solid Tumor Progression, Deng Pan

Dissertations and Theses (Open Access)

The transcription factor NF-κB plays a central role in many aspects of biological processes and diseases, such as inflammation and cancer. Although it has been suggested thatNF-κB is critical in tumorigenesis and tumor progression, the molecular mechanism by which NF-κB is activated in solid tumor remains largely unknown. In the current work, we focus on growth factor receptor-induced NF-κB activation and tumor progression, including epidermal growth factor receptor (EGFR)-induced NF-κB in lung cancer and heregulin receptor (HER2)-induced NF-κB in breast cancer. We found that Mucosa-associated lymphoma translocation protein 1 (MALT1), also known as paracaspase, is required for EGFR-induced NF-κB activation …

The Effect Of Nitrate On The Release Of Glucose Into The Hemolymph Of Crayfish, Procambarus Clarkii, Alec R. Flores, Lee Kats, David Green, Gary Bucciarelli

Seaver College Research And Scholarly Achievement Symposium

Pollutants can change the behaviors of invertebrate stream animals. The level of one common pollutant, nitrate (NO3), has been rising in many local rivers and streams throughout the United States due to increases in anthropogenic sources. Nitrate, heavily regulated for its toxic effects to human health, namely the aiding in the development of cancer, also dangerously affects aquatic species by converting oxygen-carrying pigments to forms that are incapable of carrying oxygen. To understand the stress effects of ambient nitrate exposure on P. clarkii, we collected hemolymph samples from red swamp crayfish (Procambarus clarkii) over a 48-hour period after exposure to …

Localized Jnk Signaling Regulates Organ Size During Development., Helen Rankin Willsey, Xiaoyan Zheng, José Carlos Pastor-Pareja, A Jeremy Willsey, Philip A Beachy, Tian Xu

Anatomy and Regenerative Biology Faculty Publications

A fundamental question of biology is what determines organ size. Despite demonstrations that factors within organs determine their sizes, intrinsic size control mechanisms remain elusive. Here we show that Drosophila wing size is regulated by JNK signaling during development. JNK is active in a stripe along the center of developing wings, and modulating JNK signaling within this stripe changes organ size. This JNK stripe influences proliferation in a non-canonical, Jun-independent manner by inhibiting the Hippo pathway. Localized JNK activity is established by Hedgehog signaling, where Ci elevates dTRAF1 expression. As the dTRAF1 homolog, TRAF4, is amplified in numerous cancers, these …

Development And Validation Of A Sensitive Uplc-Ms/Ms Method For The Quantitation Of [13c]Sucrose In Rat Plasma, Blood, And Brain: Its Application To The Measurement Of Blood-Brain Barrier Permeability, Mohammad K. Miah, Ulrich Bickel, Reza Mehvar

Pharmacy Faculty Articles and Research

Accurate and reproducible measurement of blood-brain barrier (BBB) integrity is critical in the assessment of the pathophysiology of the central nervous system disorders and in monitoring therapeutic effects. The widely-used low molecular weight marker [14C]sucrose is non-specific in the absence of chromatographic separation. The purpose of this study was to develop and validate a sensitive and reproducible LC-MS/MS method for the analysis of stable isotopemodified [13C12]sucrose in brain, plasma, and blood to determine BBB permeability to sucrose. After addition of internal standard (IS, [13C6]sucrose), the marker and IS were recovered from diluted rat blood, plasma, and brain homogenate by protein …

Adult Gli2+/-;Gli3Δ699/+ Male And Female Mice Display A Spectrum Of Genital Malformation., Fei He, Pedram Akbari, Rong Mo, Jennifer J Zhang, Chi-Chung Hui, Peter C. Kim, Walid A Farhat

Surgery Faculty Publications

Disorders of sexual development (DSD) encompass a broad spectrum of urogenital malformations and are amongst the most common congenital birth defects. Although key genetic factors such as the hedgehog (Hh) family have been identified, a unifying postnatally viable model displaying the spectrum of male and female urogenital malformations has not yet been reported. Since human cases are diagnosed and treated at various stages postnatally, equivalent mouse models enabling analysis at similar stages are of significant interest. Additionally, all non-Hh based genetic models investigating DSD display normal females, leaving female urogenital development largely unknown. Here, we generated compound mutant mice, Gli2+/-;Gli3Δ699/+, …

Single-Cell Mass Spectrometry For Discovery Proteomics: Quantifying Translational Cell Heterogeneity In The 16-Cell Frog (Xenopus) Embryo, Camille Lombard-Banek, Sally Ann Moody, Peter Nemes

Anatomy and Regenerative Biology Faculty Publications

We advance mass spectrometry from a cell population-averaging tool to one capable of quantifying the expression of diverse proteins in single embryonic cells. Our instrument combines capillary electrophoresis (CE), electrospray ionization, and a tribrid ultrahigh-resolution mass spectrometer (HRMS) to enable untargeted (discovery) proteomics with ca. 25 amol lower limit of detection. CE-μESI-HRMS enabled the identification of 500–800 nonredundant protein groups by measuring 20 ng, or <0.2% of the total protein content in single blastomeres that were isolated from the 16-cell frog (Xenopus laevis) embryo, amounting to a total of 1709 protein groups identified between n=3 biological replicates. By quantifying ≈150 nonredundant protein groups between all blastomeres and replicate measurements, we found significant translational cell heterogeneity along multiple axes of the embryo at this very early stage of development when the transcriptional program of the embryo has yet to begin.

Chronic Pancreatitis, Pain, And Anxiety In An Alcohol And High Fat Mouse Model, Tiffanie Clinkinbeard

Theses and Dissertations--Gerontology

Homeodynamic space (HDS) shrinks as vulnerability increases with aging and repeated damage to the cells. HDS is lost in alcoholic pancreatitis patients due to overconsumption of alcohol, smoking, and high fat diets. Etiologically relevant animal models for study of chronic pancreatitis (CP) are needed. In order to begin filling this gap a central purpose of this dissertation research was to examine relationships between the alcohol and high fat diet (AHF) and pancreatitis with attention to hypersensitivity and anxiety-like behaviors. The AHF diet induced pancreatitis described here etiologically mimics human risk factors of AHF consumption for advancement to alcoholic CP.

To accomplish this, we used seven research Beagle dogs. An axial corneal alkali burn in dogs was created using 1 N NaOH topically. Six dogs were randomly and equally assigned into 2 groups: A) vehicle (DMSO, 2 μL/mL); B) anti-fibrotic treatment (50 μM SAHA). The degree of corneal opacity, ocular health, and anti-fibrotic effects of SAHA were determined utilizing the Fantes grading …

Molecular Mechanisms Of Suberoylanilide Hydroxamic Acid In The Inhibition Of Tgf-Β1-Mediated Canine Corneal Fibrosis, Kristina M. Gronkiewicz, Elizabeth A. Giuliano, Ajay Sharma, Rajiv R. Mohan

Pharmacy Faculty Articles and Research

Objective—To investigate molecular mechanisms mediating anti-fibrotic effect of SAHA in the canine cornea using an in vitro model. We hypothesized that SAHA attenuates corneal fibrosis by modulating Smad-dependent and, to a lesser extent, Smad-independent signaling pathways activated by TGF-β1, as well as matrix metalloproteinase (MMP) activity.

Methods—Cultured canine corneal fibroblasts (CCF) were incubated in the presence/absence of TGF-β1 (5ng/ml) and SAHA (2.5μM) for 24hrs. Western blot analysis was used to quantify non-phosphorylated and phosphorylated isoforms of Smad2/3, p38 MAP kinase (MAPK), ERK1/2 and JNK1. Real-time PCR and zymography were utilized to quantify MMP1, MMP2, MMP8 and MMP9 mRNA expression and …

With an increase in anthelmintic resistance and decreased efficacy of many commercial dewormers, understanding factors that contribute to parasite infestations in horses is integral to their management. The goal of this study was to look at the potential relationship between parasites and stress response by evaluating salivary cortisol levels and cyathostome egg shedding levels. Using a sample size of n = 200 horses from the state of Ohio, fecal and saliva samples were collected from each horse. Fecal egg counts were performed for each horse with a modified Stoll method, and saliva samples were tested with an enzyme-linked immunosorbent assay …

Animal Mourning: Précis Of How Animals Grieve (King 2013), Barbara J. King

Animal Sentience

Abstract: When an animal dies, that individual’s mate, relatives, or friends may express grief. Changes in the survivor’s patterns of social behavior, eating, sleeping, and/or of expression of affect are the key criteria for defining grief. Based on this understanding of grief, it is not only big-brained mammals like elephants, apes, and cetaceans who can be said to mourn, but also a wide variety of other animals, including domestic companions like cats, dogs, and rabbits; horses and farm animals; and some birds. With keen attention placed on seeking where grief is found to occur and where it is absent …
