The Induction Of Emt And Activation Of Adipose Stem Cells In Correlation With The Secretion Of Ltbp-1 In Mammary Cells, Roshni Malik, Lauren Griggs, Dr. Christopher Lemmon Phd

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

This work is part of an ongoing study that investigates the upregulation of LTBP-1 in mammary epithelial cells as well as the differentiation of breast adipose stem cells (BASCs) in the presence of TGF-β1. Through immunofluorescence imaging, LTBP-1 is shown to co-localize with fibronectin fibrils in adipose stem cells. Previous work from our lab has shown that blocking fibronectin fibril formation can inhibit Epithelial-Mesenchymal Transition. Thus, targeting of fibronectin assembly could be a potent new therapeutic in cancer treatment. In the current work, we focus on the pharmacodynamics of a FN assembly inhibitor derived from the protein Adhesin F1 (refered …

Osseointegration Of Wrapped Dental Implants In Rabbits, Alex Whitehead

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

Edentulous patients (those lacking teeth) require one of two approaches to augmentation: inserting a vertical bone graft, or subperiosteally anchoring a device on which an implant can be attached. Bone grafts have had unpredictable results and can undergo resorption over time, compromising implant stability and success. As of the subperiosteal approach, current materials have not proven to directly integrate with the bone, in a process termed osseointegration. Therefore, we used additive manufacturing to create a Ti6Al4V alloy surface with a specific roughness to determine if it would be osseoinductive in a challenging rabbit model over six weeks.

Computer Simulation Of Tooth Mobility Using Varying Material Properties, Allison R. Beckmann, Lena Unterberg, Stefan Raith, Horst Fischer

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

Tooth mobility is the major cause of stress on a tooth implant or partial denture and often results in the damage of the device. For many prosthetic devices like dental bridges, a partial denture used for a person who is missing a tooth to give the appearance and function of a tooth, mobility can cause up to double the amount of stress in comparison to a fixed model. Creating a computer simulation of tooth mobility using Finite Element Analysis allows one to understand and predict this movement in order to improve future dental prosthetic devices. The main cause of tooth …

Endogenous Bdnf Augments Nmda Receptor Phosphorylation In The Spinal Cord Via Plcγ, Pkc, And Pi3k/Akt Pathways During Colitis, Miao Liu, Jarren C. Kay, Shanwei Shen, Li-Ya Qiao

Physiology and Biophysics Publications and Presentations

Background

Spinal central sensitization is an important process in the generation and maintenance of visceral hypersensitivity. The release of brain-derived neurotrophic factor (BDNF) from the primary afferent neurons to the spinal cord contributes to spinal neuronal plasticity and increases neuronal activity and synaptic efficacy. The N-Methyl-D-aspartic acid (NMDA) receptor possesses ion channel properties, and its activity is modulated by phosphorylation of its subunits including the NMDA receptor 1 (NR1).

Methods

Colonic inflammation was induced by a single dose of intracolonic instillation of tri-nitrobenzene sulfonic acid (TNBS). NR1 phosphorylation by BDNF in vivo and in culture was examined by western …

Molecular Overlap In The Regulation Of Sk Channels By Small Molecules And Phosphoinositides, Miao Zhang, Xuan-Yu Meng, Ji-Fang Zhang, Meng Cui, Diomedes E. Logothetis

Physiology and Biophysics Publications and Presentations

Phosphatidylinositol 4,5-bisphosphate (PIP2) directly interacts with the small-conductance Ca2+-activated K+2-a (SK2-a) channel/calmodulin complex, serving as a critical element in the regulation of channel activity. We report that changes of protein conformation in close proximity to the PIP2 binding site induced by a small-molecule SK channel modulator, NS309, can effectively enhance the interaction between the protein and PIP2 to potentiate channel activity. This novel modulation of PIP2 sensitivity by small-molecule drugs is likely not to be limited in its application to SK channels, representing an intriguing strategy to develop drugs controlling the activity of the large number of PIP2-dependent proteins.

Impact Of V-Ets Erythroblastosis Virus E26 Oncogene Homolog 1 Gene Polymorphisms Upon Susceptibility To Autoimmune Diseases, Ye Zhou, Miao Liu, Jun Li, Fiza Hashmi, Zhi Mao, Ning Zhang, Liang Zhou, Weiran Lv, Jingwei Zheng, Xiaoli Nie, Changzheng Li

Physiology and Biophysics Publications and Presentations

V-ets erythroblastosis virus E26 oncogene homolog 1 (ETS1) is recognized as a gene of risk to autoimmune diseases (ADs). Two single nucleotide polymorphisms (SNPs) in ETS1 (rs1128334 G>A and rs10893872 T>C) were considered associated with ADs risk. However, the results remain conflicting.

We performed a meta-analysis to evaluate more precise estimations of any relationship. We searched PubMed, OvidSP, and Chinese National Knowledge Infrastructure databases (papers published prior to September 12, 2014) and extracted data from eligible studies. Meta-analysis was performed using the STATA 12.0 software. Random effect model or fixed effect model were chosen according to …

Editorial: Phosphoinositides And Their Phosphatases: Linking Electrical And Chemical Signals In Biological Processes, Susy C. Kohout, Carlos A. Villalba-Galea

Physiology and Biophysics Publications and Presentations

The voltage-sensing phosphatase (VSP) has changed the way we think about both cellular electrical activity and PIPs (phosphatidylinositol phosphates). Originally discovered in 1999 (Chen et al., 1999), these proteins were not recognized as electrically-controlled enzymes until 2005 (Murata et al., 2005). They constitute the first, and so far the only, example of an enzyme linking electrical signals at the plasma membrane to the catalysis of PIPs (Murata et al., 2005), a ubiquitous family of intracellular signaling molecules (Di Paolo and De Camilli, 2006; Balla, 2013). Before the discovery of VSP, there were no known direct links between the two. Textbook …

Pancreatic ductal adenocarcinoma (PDA) is the fourth leading cause of cancer-related deaths in the United States, and is projected to be second by 2025. It has the worst survival rate among all major cancers. Two pressing needs for extending life expectancy of affected individuals are the development of new approaches to identify improved therapeutics, addressed herein, and the identification of early markers. PDA advances through a complex series of intercellular and physiological interactions that drive cancer progression in response to organ stress, organ failure, malnutrition, and infiltrating immune and stromal cells. Candidate drugs identified in organ culture or cell-based screens …

Nicotinic Acetylcholine Receptor (Nachr) Dependent Chorda Tympani Taste Nerve Responses To Nicotine, Ethanol And Acetylcholine, Zuo Jun Ren, Shobha Mummalaneni, Jie Qian, Clive M. Baumgarten, John A. Desimone, Vijay Lyall

Physiology and Biophysics Publications and Presentations

Nicotine elicits bitter taste by activating TRPM5-dependent and TRPM5-independent but neuronal nAChR-dependent pathways. The nAChRs represent common targets at which acetylcholine, nicotine and ethanol functionally interact in the central nervous system. Here, we investigated if the nAChRs also represent a common pathway through which the bitter taste of nicotine, ethanol and acetylcholine is transduced. To this end, chorda tympani (CT) taste nerve responses were monitored in rats, wild-type mice and TRPM5 knockout (KO) mice following lingual stimulation with nicotine free base, ethanol, and acetylcholine, in the absence and presence of nAChR agonists and antagonists. The nAChR modulators: mecamylamine, dihydro-β-erythroidine, and …

Starvation-Induced Collective Behavior In C. Elegans, Alexander B. Artyukhin, Virginia Commonwealth University J. Yim, Mi Cheong Cheong, Leon Avery

Physiology and Biophysics Publications and Presentations

We describe a new type of collective behavior in C. elegans nematodes, aggregation of starved L1 larvae. Shortly after hatching in the absence of food, L1 larvae arrest their development and disperse in search for food. In contrast, after two or more days without food, the worms change their behavior—they start to aggregate. The aggregation requires a small amount of ethanol or acetate in the environment. In the case of ethanol, it has to be metabolized, which requires functional alcohol dehydrogenase sodh-1. The resulting acetate is used in de novo fatty acid synthesis, and some of the newly made fatty …

An Opioid-Like System Regulating Feeding Behavior In C. Elegans, Mi Cheong Cheong, Alexander B. Artyukhin, Yong-Jai You, Leon Avery

Physiology and Biophysics Publications and Presentations

Neuropeptides are essential for the regulation of appetite. Here we show that neuropeptides could regulate feeding in mutants that lack neurotransmission from the motor neurons that stimulate feeding muscles. We identified nlp-24 by an RNAi screen of 115 neuropeptide genes, testing whether they affected growth. NLP-24 peptides have a conserved YGGXX sequence, similar to mammalian opioid neuropeptides. In addition, morphine and naloxone respectively stimulated and inhibited feeding in starved worms, but not in worms lacking NPR-17, which encodes a protein with sequence similarity to opioid receptors. Opioid agonists activated heterologously expressed NPR-17, as did at least one NLP-24 peptide. Worms …

Proof-Of-Concept Of Environmental Dna Tools For Atlantic Sturgeon Management, Jameson Hinkle

Theses and Dissertations

Abstract

The Atlantic Sturgeon (Acipenser oxyrinchus oxyrinchus, Mitchell) is an anadromous species that spawns in tidal freshwater rivers from Canada to Florida. Overfishing, river sedimentation and alteration of the river bottom have decreased Atlantic Sturgeon populations, and NOAA lists the species as endangered. Ecologists sometimes find it difficult to locate individuals of a species that is rare, endangered or invasive. The need for methods less invasive that can create more resolution of cryptic species presence is necessary. Environmental DNA (eDNA) is a non-invasive means of detecting rare, endangered, or invasive species by isolating nuclear or mitochondrial DNA (mtDNA) from the …

Identification Of The Conformational Transition Pathway In Pip2 Opening Kir Channels, Junwei Li, Shouqin Lü, Yuzhi Liu, Chunli Pang, Yafei Chen, Suhua Zhang, Hui Yu, Mian Long, Hailin Zhang, Diomedes E. Logothetis, Yong Zhan, Hailong An

Physiology and Biophysics Publications and Presentations

The gating of Kir channels depends critically on phosphatidylinositol 4,5-bisphosphate (PIP2), but the detailed mechanism by which PIP2regulates Kir channels remains obscure. Here, we performed a series of Targeted molecular dynamics simulations on the full-length Kir2.1 channel and, for the first time, were able to achieve the transition from the closed to the open state. Our data show that with the upward motion of the cytoplasmic domain (CTD) the structure of the C-Linker changes from a loop to a helix. The twisting of the C-linker triggers the rotation of the CTD, which induces a small downward movement of the CTD …

Addition Of Interleukin-21 For Expansion Of T-Cells For Adoptive Immunotherapy Of Murine Melanoma, Christine Kathryn Zoon, Wen Wan, Laura Graham, Harry D. Bear

Surgery Publications

We previously demonstrated that interleukin (IL)-7/15 was superior to IL-2 for expansion of T cells in vitrofor adoptive immunotherapy. We sought to ascertain whether IL-21 would further improve yield and therapeutic efficacy of T cells in culture. Naïve T cell receptor (TcR) transgenic splenocytes or antigen-sensitized lymph node cells were harvested from PMEL-1 mice and exposed to bryostatin-1 and ionomycin (B/I) for 18 h. Cells were then cultured in IL-2, IL-21, IL-7/15 or IL-7/15/21 for six days. Harvested cells were analyzed by flow cytometry and used to treat C57Bl/6 mice injected intravenously with B16 melanoma. Lungs were harvested and …

Deconstructing Anesthesia Handoffs During Simulated Intraoperative Anesthesia Care, Jason S. Lowe

Theses and Dissertations

Anesthesia patient handoffs are a vulnerable time for patient care and handoffs occur frequently during anesthesia care. Communication failures contribute to patient harm during anesthesia patient handoffs. The Joint Commission has recognized the potential for communication failure during patient handoffs and has recommended processes to improve handoff safety. Handoffs are made more difficult by latent conditions such as time constraints, pressure and distractions, which often result in incomplete or inaccurate handoff reports. This nonexperimental, correlation study identified the latent conditions that occur during the handoff process and their relationship to the quality of the handoff. This research shows an inverse …

Elucidation Of A Novel Pathway In Staphylococcus Aureus: The Essential Site-Specific Processing Of Ribosomal Protein L27, Erin A. Wall

Theses and Dissertations

Ribosomal protein L27 is a component of the eubacterial large ribosomal subunit that has been shown to play a critical role in substrate stabilization during protein synthesis. This function is mediated by the L27 N-terminus, which protrudes into the peptidyl transferase center where it interacts with both A-site and P-site tRNAs as well as with 23S rRNA. We observed that L27 in S. aureus and other Firmicutes is encoded with a short N-terminal extension that is not present in most Gram-negative organisms, and is absent from mature ribosomes. The extension contains a conserved cleavage motif; nine N-terminal amino acids are …

The Slc22 Transporter Family: Novel Insights To Roles In Drug Efficacy, Drug-Drug Interactions And Mood Disorders, Xiaolei Pan

Theses and Dissertations

Numerous studies have demonstrated the impact of organic cation (OCTs; SLC22 family) and anion transporters (OATs; SLC22 family) on the efficacy and safety of clinically important therapeutics. To be specific, OCTs and OATs have been identified as determinants for uptake into and secretion from enterocytes, hepatocytes and renal proximal tubular cells, and are frequent sites of drug-drug interaction (DDI). In addition, OCTs expressed in brain are components of the low-affinity, high capacity clearance pathway (uptake-2) for biogenic monoamine neurotransmitters. As a result, OCTs may represent novel targets for mood disorders.

The inhibitory effects of several therapeutic agents, designed drugs and …

The Effect Of Optogenetic Manipulation Of Ss Interneurons Within Malformed, Epileptogenic Cortex, Nicole Ekanem

Theses and Dissertations

A large percentage of individuals with intractable epilepsies have an accompanying cortical malformation, the underlying cellular mechanisms of which are poorly understood. It is known however that in an animal model for one such malformation, polymicrogyria, epileptogenesis occurs most easily from an adjacent area termed the paramicrogyral region (PMR). Previous studies implicate SS interneurons as a potential contributor to this pathology, which lead to our hypothesis: in PMR, SS interneurons exert a higher modulatory influence on excitatory pyramidal cells, as compared to the same by SS interneurons within homologous control cortex.

Using a freeze-lesion model for polymicrogyria in transgenic mice …

Reproductive Health And Behavior: The Role Of Abuse And Couple Pregnancy Intent, Susan Cha

Background: Rapid repeat pregnancy (RRP), a pregnancy occurring less than 24 months from a prior birth, and unintended pregnancy-related induced abortions can be prevented with family planning. However, few studies have adequately addressed the role of male partners in reproductive decision-making. Objectives: The goal of this research is to understand the interrelationships between couple pregnancy intention, intimate partner violence (IPV), reproductive health and behaviors. Specifically, this project aims to: (1) examine the extent to which couple pregnancy intentions are associated with RRP and (2) induced abortions among women in the U.S., and (3) examine the extent to which …

Risperidone And Its Deconstructed Analogs: Functional Effects On The 5ht2ar, Sneha Shah

Theses and Dissertations

G protein-coupled receptors (GPCRs) are seven-transmembrane domain receptors that sense extracellular signal and activate intracellular signaling pathways. The serotonin 5HT2A receptor (or 2AR) is one of the GPCRs coupled to Gq proteins, activating PLC and hydrolyzing PIP2. This hydrolysis causes a diffusion of bound PIP2 away from the channel binding site resulting in G protein-gated inwardly rectifying K⁺ channel (GIRK) inhibition and a downstream stimulation of Ca²⁺ release from endoplasmic reticulum stores. Previous experiments have demonstrated that the serotonin 5HTA receptor is a target of serotonergic psychedelic drugs, such as LSD, and partially mediates the action of many …

Mitochondrial Biogenesis And Electrical Properties Of Hpsc-Derived Motor Neurons, Laura O'Brien

Theses and Dissertations

Human pluripotent stem cells (hPSCs), including human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs) hold great promise in the fields of drug development and regenerative medicine. If iPSCs reprogrammed from patient cells replicate what is seen in vivo they may be used as a model of disease. A process that is disrupted in many neurodegenerative diseases is mitochondrial biogenesis. One of these diseases is amyotrophic lateral sclerosis (ALS), which is characterized by loss of motor neurons in the brain and spinal cord. Differentiation of hPSCs into motor neurons offers a way to study a previous unavailable cell …
