Alterations In Calcium Homeostasis And The Insulin-Like Growth Factor Signaling Pathway Induced By Carcinogenic Polycyclic And Halogenated Aromatic Hydrocarbons In Human Mammary Epithelial Cells, Stacey L. Tannheimer

Pharmaceutical Sciences ETDs

Breast cancer is a major health concern for women, with only a small percent of the risk factors currently identified. It has been estimated that environmental factors may contribute to up to 80% of breast cancer cases. Many environmental carcinogens, such as polycyclic and halogenated aromatic hydrocarbons (PAHs and HAHs), are proven mammary carcinogens in animal models. Therefore, these studies were conducted to elucidate potential roles of PAHs and HAHs in alterations in known signaling pathways in human mammary epithelial cells (HMEC). Carcinogenic PAHs have previously been shown to produce sustained alterations in the calcium (Ca2') homeostasis of lymphocytes Therefore, …

Interaction Of Gaba And Excitatory Amino Acids In The Basolateral Amygdala: Role In Cardiovascular Regulation, Robert P. Soltis, Jennifer C. Cook, Adam E. Gregg, Brian J. Sanders

Scholarship and Professional Work – COPHS

Activation of the amygdala in rats produces cardiovascular changes that include increases in heart rate and arterial pressure as well as behavioral changes characteristic of emotional arousal. The objective of the present study was to examine the interaction of GABA and excitatory amino acid (EAA) receptors in the basolateral amygdala (BLA) in regulating cardiovascular function. Microinjection of the GABA_A receptor antagonist bicuculline methiodide (BMI) or the E A A receptor agonists NMDA or AMPA into the same region of the BLA of conscious rats produced dose-related increases in heart rate and arterial pressure. Injection of the nonselective EAA receptor …

Chronic Hypothermia And Energy Expenditure In A Neurodevelopmentally Disabled Patient: A Case Study, Jane M. Gervasio, Roland N. Dickerson, Rex O. Brown, J. Barret Matthews

Scholarship and Professional Work – COPHS

Hypothermia is defined as a core body temperature of <35°C and results in a decrease in measured resting energy expenditure. A 51-year-old mentally disabled patient experienced chronic hypothermia from neurologic sequelae. Because of her continued weight gain and increased body fat in the presence of presumed hypocaloric nutrition, indirect calorimetry measurements were performed twice in a 3-month period. The resting energy expenditure measurements prompted a reduction of her daily caloric intake to prevent further overfeeding. Hypothermia reduces oxygen consumption and, as a consequence, decreases resting energy expenditure. In patients for whom chronic hypothermia is a problem, nutritional intake must be adjusted to prevent overfeeding, excessive weight gain, and the long-term complications of an excess of total calories.

Alterations In Human B Cell Calcium Homeostasis By Polycyclic Aromatic Hydrocarbons: Possible Associations With Cytochrome P450 Metabolism And Increased Tyrosine Phosphorylation, Barbara J. Mounho

Pharmaceutical Sciences ETDs

Polycyclic aromatic hydrocarbons (PAHs), are known immunotoxicants in animals, and are suspect toxins to the human immune system. The mechanism(s), however, by which PAHs exert immunosuppression have not been fully elucidated. Previous studies conducted in our laboratory have shown that PAHs, such as 7,12-dimethylbenz(a)- anthracene (DMB A) and benzo(a)pyrene (BaP) may exert their immunotoxic effects by altering intracellular calcium (Ca2+) homeostasis in lymphocytes. Intracellular Ca2+ is an important second messenger in the immune response, and the mobilization of Ca2+ is critical in the transduction of intracellular signals from the plasma membrane to the nucleus. The overall objective of this project …

Enhancing Compliance With Allergic Rhinitis Therapy, Beth Wofford, Deborah S. Zeitlin

Scholarship and Professional Work – COPHS

Allergic rhinitis is one of the most common chronic conditions in the US, surpassing even heart disease. Over $1 billion is spent annually for over-the-counter (OTC) and prescription medications. In addition, allergic rhinitis causes an estimated annual loss of $639 million related to lost work days and diminished work performance.

If not effectively treated, allergic rhinitis may lead to potential complications such as otitis media, sinusitis, facial and dental abnormalities, hearing loss, poor speech development, and recurrent upper respiratory tract infections. Ineffective treatment often the result of intentional or unintentional noncompliance and inadequate patient education. Therefore, it is imperative that …

Tyrosine 140 Of The Γ-Aminobutyric Acid Transporter Gat-1 Plays A Critical Role In Neurotransmitter Recognition, Yona Bismuth, Michael Kavanaugh, Baruch I. Kanner

Biomedical and Pharmaceutical Sciences Faculty Publications

The γ-aminobutyric acid (GABA) transporter GAT-1 is located in nerve terminals and catalyzes the electrogenic reuptake of the neurotransmitter with two sodium ions and one chloride. We now identify a single tyrosine residue that is critical for GABA recognition and transport. It is completely conserved throughout the superfamily, and even substitution to the other aromatic amino acids, phenylalanine (Y140F) and tryptophan (Y140W), results in completely inactive transporters. Electrophysiological characterization reveals that both mutant transporters exhibit the sodium-dependent transient currents associated with sodium binding as well as the chloride-dependent lithium leak currents characteristic of GAT-1. On the other hand, in both …

Mutation Of An Amino Acid Residue Influencing Potassium Coupling In The Glutamate Transporter Glt-1 Induces Obligate Exchange, Michael Kavanaugh, Annie Bendahan, Noa Zerangue, Yumin Zhang, Baruch I. Kanner

Biomedical and Pharmaceutical Sciences Faculty Publications

Glutamate transporters maintain low synaptic concentrations of neurotransmitter by coupling uptake to flux of other ions. After cotransport of glutamic acid with Na⁺, the cycle is completed by countertransport of K⁺. We have identified an amino acid residue (glutamate 404) influencing ion coupling in a domain of the transporter implicated previously in kainate binding. Mutation of this residue to aspartate (E404D) prevents both forward and reverse transport induced by K⁺. Sodium-dependent transmitter exchange and a transporter-mediated chloride conductance are unaffected by the mutation, indicating that this residue selectively influences potassium flux coupling. The results …

Excitatory Amino Acid Transporter 5, A Retinal Glutamate Transporter Coupled To A Chloride Conductance, Jeffrey L. Arriza, Scott Eliasof, Michael Kavanaugh, Susan G. Amara

Biomedical and Pharmaceutical Sciences Faculty Publications

Although a glutamate-gated chloride conductance with the properties of a sodium-dependent glutamate transporter has been described in vertebrate retinal photoreceptors and bipolar cells, the molecular species underlying this conductance has not yet been identified. We now report the cloning and functional characterization of a human excitatory amino acid transporter, EAAT5, expressed primarily in retina. Although EAAT5 shares the structural homologies of the EAAT gene family, one novel feature of the EAAT5 sequence is a carboxy-terminal motif identified previously in N-methyl-d-aspartate receptors and potassium channels and shown to confer interactions with a family of synaptic proteins that promote ion channel …

Multiple Ionic Conductances Of The Human Dopamine Transporter: The Actions Of Dopamine And Psychostimulants, Mark S. Sonders, Si-Jia Zhu, Nancy R. Zahniser, Michael Kavanaugh, Susan G. Amara

Biomedical and Pharmaceutical Sciences Faculty Publications

Electrophysiological and pharmacological studies of a cloned human dopamine transporter (hDAT) were undertaken to investigate the mechanisms of transporter function and the actions of drugs at this target. Using two-electrode voltage-clamp techniques with hDAT-expressing Xenopus laevis oocytes, we show that hDAT can be considered electrogenic by two criteria. (1) Uptake of hDAT substrates gives rise to a pharmacologically appropriate “transport-associated” current. (2) The velocity of DA uptake measured in oocytes clamped at various membrane potentials was voltage-dependent, increasing with hyperpolarization. Concurrent measurement of transport-associated current and substrate flux in individual oocytes revealed that charge movement during substrate translocation was greater …

Aspartate 19 And Glutamate 121 Are Critical For Transport Function Of The Myo-Inositol/H+ Symporter From Leishmania Donovani, Andreas Seyfang, Michael Kavanaugh, Scott M. Landfear

Biomedical and Pharmaceutical Sciences Faculty Publications

The protozoan flagellate Leishmania donovani has an active myo-inositol/proton symporter (MIT), which is driven by a proton gradient across the parasite membrane. We have used site-directed mutagenesis in combination with functional expression of transporter mutants in Xenopusoocytes and overexpression in Leishmania transfectants to investigate the significance of acidic transmembrane residues for proton relay and inositol transport. MIT has only three charged amino acids within predicted transmembrane domains. Two of these residues, Asp¹⁹ (TM1) and Glu¹²¹ (TM4), appeared to be critical for transport function of MIT, with a reduction of inositol transport to about 2% of wild-type …
