Dietary zinc (Zn) deficiency (ZD) in rats induces an inflammatory gene signature that fuels esophageal squamous cell cancer (ESCC). Using nanoStringTM technology, we show that the inflammation is accompanied by altered expression of specific microRNAs in esophagus, as well as skin, lung, pancreas, liver, prostate, and PBMC, predictive of disease development. Particularly, the ZD esophagus has a microRNA signature resembling human ESCC/tongue SCC miRNAomes with overexpression of miR-31 and miR-21 and downregulation of their respective tumor suppressor targets PPP2R2A and …

Anabolic And Androgenic Effects Of Certain Atriplex Species Grown In Egypt, Dina M. El-Kersh, Fatma S. El-Sakhawy, Dina R. Abou-Hussein, Amany A. Sleem

Pharmacy

20-Hydroxyecdysone (20-HE) was detected by TLC in the ethyl acetate fraction of two Atriplex species grown in Egypt: A. lindleyi subsp. inflata and A. leucoclada. EIA quantification of 20-HE proved its presence in a concentration of 9.15 and 7.3 μg/g dried aerial parts in each of the two species, respectively. Significant anabolic and androgenic activities were demonstrated for 20-HE comparing to testosterone; the study also revealed that the total alcohol extract and the ethyl acetate fraction of A. lindleyi subsp. inflata exhibited greater activities than their analogues in A. leucoclada. Column chromatographic fractionation of the ethyl acetate fraction of the …

Molecular Mechanism For Depolarization-Induced Modulation Of Kv Channel Closure, Alain J. Labro, Jerome J. Lacroix, Carlos A. Villalba-Galea, Dirk J. Snyders, Francisco Bezanilla

School of Pharmacy Faculty Articles

Voltage-dependent potassium (Kv) channels provide the repolarizing power that shapes the action potential duration and helps control the firing frequency of neurons. The K(+) permeation through the channel pore is controlled by an intracellularly located bundle-crossing (BC) gate that communicates with the voltage-sensing domains (VSDs). During prolonged membrane depolarizations, most Kv channels display C-type inactivation that halts K(+) conduction through constriction of the K(+) selectivity filter. Besides triggering C-type inactivation, we show that in Shaker and Kv1.2 channels (expressed in Xenopus laevis oocytes), prolonged membrane depolarizations also slow down the kinetics of VSD deactivation and BC gate closure during the …

A Human Phospholipid Phosphatase Activated By A Transmembrane Control Module, Christian R. Halaszovich, Michael G. Leitner, Angeliki Mavrantoni, Audrey Le, Ludivine Frezza, Anja Feuer, Daniela N. Schreiber, Carlos A. Villalba-Galea, Dominik Oliver

School of Pharmacy Faculty Articles

In voltage-sensitive phosphatases (VSPs), a transmembrane voltage sensor domain (VSD) controls an intracellular phosphoinositide phosphatase domain, thereby enabling immediate initiation of intracellular signals by membrane depolarization. The existence of such a mechanism in mammals has remained elusive, despite the presence of VSP-homologous proteins in mammalian cells, in particular in sperm precursor cells. Here we demonstrate activation of a human VSP (hVSP1/TPIP) by an intramolecular switch. By engineering a chimeric hVSP1 with enhanced plasma membrane targeting containing the VSD of a prototypic invertebrate VSP, we show that hVSP1 is a phosphoinositide-5-phosphatase whose predominant substrate is PI(4,5)P(2). In the chimera, enzymatic activity …

Development Of The Sustained Release Analgesic Formulations For Rodents And A Novel In Vitro Model For Parenteral Formulations With The Character Of A Level A Ivivc, Jin Xu

Theses and Dissertations (ETD)

Laboratory animals are often subjected to various painful surgical procedures such as laparotomy, thoracotomy or orthopedic procedures as well as non-surgical procedures such as the induction of arthritis. Any procedure that causes pain in humans is assumed to cause pain in animals too. It is the ethical obligation of all research personnel to reduce or preferably eliminate pain and distress by using analgesics. Furthermore, the Institutional Animal Care and Use Committee (IACUC) requires that appropriate anesthetics and/or analgesics must be used to minimize or eliminate pain and distress for animals undergoing painful procedures.

The oral administration route is the most …

Development And Validation Of A Simple Method For The Detection Of Fascaplysin In Plasma, Kenneth H. Swartz, Frederick A. Valeriote, Joseph Media, Tyler A. Johnson, Karen Tenney, Phillip Crews, Jiajiu Shaw

Natural Sciences and Mathematics | Faculty Scholarship

Fascaplysin is a cytotoxic natural product isolated from a variety of Indo-Pacific marine organisms, primarily Fascaplysinopsis sponges and Didemnum tunicates. Positive xenograft studies involving this alkaloid structural class have indicated that fascaplysin may serve as an important lead compound for preclinical development. This study was undertaken as a prelude to a full pharmacokinetics and therapeutic assessment of fascaplysin. We describe here a simple plasma preparation and a rapid HPLC method for the detection of fascaplysin in mice. The method was validated by parameters including good linear correlation, a limit of quantification of 107.1 μg/ mL, and a good precision with …

Methods: Forty-one community outreach events were held throughout Central/Northern California during the Medicare Part D annual election periods from 2008-2011. In total, 1,578 beneficiaries were assisted, 983 (62.2%) of whom …

Double-Stranded Rna-Dependent Protein Kinase Regulates The Motility Of Breast Cancer Cells, Mei Xu, Gang Chen, Siying Wang, Mingjun Liao, Jacqueline A. Frank, Kimberly A. Bower, Zhuo Zhang, Xianglin Shi, Jia Luo

Internal Medicine Faculty Publications

Double-stranded RNA (dsRNA)-dependent protein kinase (PKR) is an interferon-induced protein kinase that plays a central role in the anti-viral process. Due to its pro-apoptotic and anti-proliferative action, there is an increased interest in PKR modulation as an anti-tumor strategy. PKR is overexpressed in breast cancer cells; however, the role of PKR in breast cancer cells is unclear. The expression/activity of PKR appears inversely related to the aggressiveness of breast cancer cells. The current study investigated the role of PKR in the motility/migration of breast cancer cells. The activation of PKR by a synthesized dsRNA (PIC) significantly decreased the motility of …

Capture And Characterization Of Dioxygen Reactive Intermediates In Cyp51 Catalysis, Gareth Kent Jennings

Theses and Dissertations

The cytochromes P450 (CYPs) are a superfamily of biological catalysts that are ubiquitous throughout the biological domain. CYPs are heme-b containing monooxygenases which oxidize substrates with the help of accessory redox partners. CYP substrates include endogenous compounds required for many biological functions and homeostasis, such as steroids, as well as the majority of clinically used drugs and environmental xenobiotics. The majority of studies that have been performed to date are on P450cam (CYP101) from Pseudomonas putida. Of the numerous reactions catalyzed by CYPs, unactivated carbon-carbon bond cleavage, is one of particular versatility. Being unique in their catalytic mechanisms, the C-C …

BACKGROUND: -We evaluated the viability of I(Kur) as a target for maintenance of sinus rhythm in patients with a history of atrial fibrillation through the testing of MK-0448, a novel I(Kur) inhibitor. METHODS AND RESULTS: -In vitro MK-0448 studies demonstrated strong inhibition of I(Kur) with minimal off-target activity. In vivo MK-0448 studies in normal anesthetized dogs demonstrated significant prolongation of the atrial refractory period compared with vehicle controls without affecting the ventricular refractory period. In studies of a conscious dog heart failure model, sustained AF was terminated with bolus intravenous MK-0448 doses of 0.03 and 0.1 mg/kg. These data led …

Activation Of Amp-Activated Protein Kinase By 3,39-Diindolylmethane (Dim) Is Associated With Human Prostate Cancer Cell Death In Vitro And In Vivo, Di Chen, Sanjeev Banerjee, Qiuzhi C. Cui, Dejuan Kong, Fazlul H. Sarkar, Q. Ping Dou

Oncology Faculty Publications

There is a large body of scientific evidence suggesting that 3,39-Diindolylmethane (DIM), a compound derived from the digestion of indole-3-carbinol, which is abundant in cruciferous vegetables, harbors anti-tumor activity in vitro and in vivo. Accumulating evidence suggests that AMP-activated protein kinase (AMPK) plays an essential role in cellular energy homeostasis and tumor development and that targeting AMPK may be a promising therapeutic option for cancer treatment in the clinic. We previously reported that a formulated DIM (BR-DIM; hereafter referred as B-DIM) with higher bioavailability was able to induce apoptosis and inhibit cell growth, angiogenesis, and invasion of prostate cancer cells. …
