Mechanism Of Amyloid Β-Protein Dimerization Determined Using Single-Molecule Afm Force Spectroscopy., Zhengjian Lv, Robin Roychaudhuri, Margaret M Condron, David B. Teplow, Yuri L. Lyubchenko

Journal Articles: Pharmaceutical Sciences

Aβ42 and Aβ40 are the two primary alloforms of human amyloid β-protein (Aβ). The two additional C-terminal residues of Aβ42 result in elevated neurotoxicity compared with Aβ40, but the molecular mechanism underlying this effect remains unclear. Here, we used single-molecule force microscopy to characterize interpeptide interactions for Aβ42 and Aβ40 and corresponding mutants. We discovered a dramatic difference in the interaction patterns of Aβ42 and Aβ40 monomers within dimers. Although the sequence difference between the two peptides is at the C-termini, the N-terminal segment plays a key role in the peptide interaction in the dimers. This is an unexpected finding …

The purpose of this research was to develop a topical microsphere delivery system in a thermosensitive 20% poloxamer 407 gel (Pluronic F127) to control release of KSL-W, a cationic antimicrobial decapeptide, for a period of 4-7 days for potential application in combat related injuries. KSL-W loaded microsphere formulations were prepared by a solvent extraction-evaporation method (water-oil-water), with poly (D,L-lactic-co-glycolic acid) (PLGA) (50 : 50, low-weight, and hydrophilic end) as the polymeric system. After optimization of the process, three formulations (A, B, and C) were prepared with different organic to water ratio of the primary emulsion while maintaining other components and …

Drug Firms, The Codification Of Diagnostic Categories, And Bias In Clinical Guidelines, Lisa Cosgrove, Emily E. Wheeler

Counseling and School Psychology Faculty Publication Series

The profession of medicine is predicated upon an ethical mandate: first do no harm. However, critics charge that the medical profession’s culture and its public health mission are being undermined by the pharmaceutical industry’s wide-ranging influence. In this article, we analyze how drug firms influence psychiatric taxonomy and treatment guidelines such that these resources may serve commercial rather than public health interests. Moving beyond a conflict-of-interest model, we use the conceptual and normative framework of institutional corruption to examine how organized psychiatry’s dependence on drug firms has distorted science. We suggest that academic-industry relationships have led to the corruption of …

Methods: Patients in a university based medical clinic with type 2 diabetes (T2DM) were analyzed in this retrospective cohort study. Patients were exposed to either PMDC or UMC. The difference in days to intervention in response to suboptimal laboratory values and time …

Pharmacological Characterization Of A Novel Non-At1, Non-At2 Angiotensin Binding Site Identified As Neurolysin, Jamala D. Swindle, Kira L. Santos, Robert C. Speth

HPD Articles

The discovery of a novel non-AT1, non-AT2 binding site for angiotensins in the rodent brain and testis that is unmasked by the organomercurial compound para-chloromercuribenzoic acid (PCMB) has catalyzed efforts to purify and characterize this protein. We recently reported that this protein is neurolysin and now report upon the specificity of this binding site for various neuropeptides. Competition binding assays in rat brain and testis used (125)I-Sar(1), Ile(8) angiotensin II (Ang II) as the radioligand in the presence of saturating concentrations of AT1 and AT2 receptor antagonists and 100 μM parachloromercuribenzoate. Primary screening of 36 peptides and other compounds at …

A student survey was conducted to determine perceptions of such things as differential treatment due to gender, level of preparedness for courses in the hard sciences, and gender performances of students in the sciences. Additionally, students’ grades of sixteen courses with a heavy hard science focus were analyzed by taking the percent of a letter grade sorted by male or female to determine if there was a significant gender difference in the final grades. Our objectives were to: 1) determine if the underrepresentation of women in some health-related jobs is due to discouragement of females to enter these professions or …

Content Uniformity Of Over-The-Counter Melatonin, Calvin Anderson, Lauren Callahan, Jacob Coleman, Yeseul Kim, Elizabeth C. Ledbetter, Rebecca Widder, Melissa J. Beck

Pharmacy and Nursing Student Research and Evidence-Based Medicine Poster Session

Dietary supplements are loosely regulated in comparison to over-the-counter and prescription drugs. Numerous tests for safety and efficacy are required before drugs can be marketed. However, the Food and Drug Administration does not require thorough examination of supplements before they are sold. Dietary supplements generally adhere to the phrase, “safe, until proven unsafe,” with safety determined solely through post-market adverse event reports. Substandard regulation of supplement manufacturing leads to warranted doubt about the safety and efficacy of dietary supplements. Within the dietary supplement market there are regulatory bodies, such as the United States Pharmacopeia (USP), that provide optional verification services …

A Dexamethasone Prodrug Reduces The Renal Macrophage Response And Provides Enhanced Resolution Of Established Murine Lupus Nephritis, Fang Yuan, Dana Tabor, Richard K. Nelson, Hongjiang Yuan, Yijia Zhang, Jenny Nuxoll, Kimberly K. Bynote, Subodh M. Lele, Dong Wang, Karen A. Gould

Journal Articles: Pharmaceutical Sciences

We evaluated the ability of a macromolecular prodrug of dexamethasone (P-Dex) to treat lupus nephritis in (NZB × NZW)F1 mice. We also explored the mechanism underlying the anti-inflammatory effects of this prodrug. P-Dex eliminated albuminuria in most (NZB × NZW)F1 mice. Furthermore, P-Dex reduced the incidence of severe nephritis and extended lifespan in these mice. P-Dex treatment also prevented the development of lupus-associated hypertension and vasculitis. Although P-Dex did not reduce serum levels of anti-dsDNA antibodies or glomerular immune complexes, P-Dex reduced macrophage recruitment to the kidney and attenuated tubulointerstitial injury. In contrast to what was observed with free dexamethasone, …

Pharmacy Faculty Articles and Research

Contradictory results have been reported with regard to the effects of various models of hepatic encephalopathy on the blood-brain barrier (BBB) permeability, which may be due partly to the use of brain concentrations of BBB markers without attention to their peripheral pharmacokinetics. The purpose of the current study was to investigate the effects of short-term portacaval anastomosis (PCA), a type B model of hepatic encephalopathy, on the peripheral pharmacokinetics and brain distribution of sodium fluorescein (FL), which is a small molecule marker of BBB passive permeability. A single 25 mg/kg dose of FL was administered intravenously to 10-day PCA and …

Pharmaceutical Sciences Faculty Publications

The proteasome is a key regulator of cellular protein homeostasis and is a clinically validated anticancer target. The immunoproteasome, a subtype of proteasome expressed mainly in hematopoietic cells, was initially recognized for its role in antigen presentation during the immune response. Recently, the immunoproteasome has been implicated in several disease conditions including cancer and autoimmune disorders, but many of the factors contributing to these pathological processes remain unknown. In particular, the codon 60 polymorphism of the PSMB9 gene encoding the β1i immunoproteasome catalytic subunit has been investigated in the context of a variety of diseases.

Crystal Structure Of 3wj Core Revealing Divalent Ion-Promoted Thermostability And Assembly Of The Phi29 Hexameric Motor Prna., Hui Zhang, James A. Endrizzi, Yi Shu, Farzin Haque, Claude Sauter, Luda S. Shlyakhtenko, Yuri L. Lyubchenko, Peixuan Guo, Young-In Chi

Journal Articles: Pharmaceutical Sciences

The bacteriophage phi29 DNA packaging motor, one of the strongest biological motors characterized to date, is geared by a packaging RNA (pRNA) ring. When assembled from three RNA fragments, its three-way junction (3WJ) motif is highly thermostable, is resistant to 8 M urea, and remains associated at extremely low concentrations in vitro and in vivo. To elucidate the structural basis for its unusual stability, we solved the crystal structure of this pRNA 3WJ motif at 3.05 Å. The structure revealed two divalent metal ions that coordinate 4 nt of the RNA fragments. Single-molecule fluorescence resonance energy transfer (smFRET) analysis confirmed …

Aryl Hydrocarbon Receptor Ligands Inhibit Igf-Ii And Adipokine Stimulated Breast Cancer Cell Proliferation, Travis B. Salisbury, Gary Z. Morris, Justin K. Tomblin, Ateeq R. Chaudhry, Carla Cook, Nalini Santanam

Pharmaceutical Science and Research

Obesity increases human cancer risk and the risk for cancer recurrence. Adipocytes secrete paracrine factors termed adipokines that stimulate signaling in cancer cells that induce proliferation. The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor that plays roles in tumorigenesis, is regulated by exogenous lipophilic chemicals, and has been explored as a therapeutic target for cancer therapy. Whether exogenous AHR ligands modulate adipokine stimulated breast cancer cell proliferation has not been investigated. We provide evidence that adipocytes secrete insulin-like growth factor 2 (IGF-2) at levels that stimulate the proliferation of human estrogen receptor (ER) positive breast cancer cells. Using …

Bile Acid Signal-Induced Phosphorylation Of Small Heterodimer Partner By Protein Kinase Cζ Is Critical For Epigenomic Regulation Of Liver Metabolic Genes, Sunmi Seok, Deepthi Kanamaluru, Zhen Xiao, Daniel Ryerson, Sung-E Choi, Kelly Suino-Powell, H. Eric Xu, Timothy D. Veenstra, Jongsook Kim Kemper

Pharmaceutical Sciences Faculty Publications

Bile acids (BAs) are recently recognized key signaling molecules that control integrative metabolism and energy expenditure. BAs activate multiple signaling pathways, including those of nuclear receptors, primarily farnesoid X receptor (FXR), membrane BA receptors, and FXR-induced FGF19 to regulate the fed-state metabolism. Small heterodimer partner (SHP) has been implicated as a key mediator of these BA signaling pathways by recruitment of chromatin modifying proteins, but the key question of how SHP transduces BA signaling into repressive histone modifications at liver metabolic genes remains unknown. Here we show that protein kinase Cζ (PKCζ) is activated by BA or FGF19 and phosphorylates …

The synthesized Kanamycin-GNPs (Kan-GNPs) were spherical in shape and had a size range of 15 ± 3 nm. The chosen kanamycin is an aminoglycosidic antibiotic that is isolated from Streptomyces kanamyceticus. These special antibiotic GNPs are further characterized using …

Development Of Tools To Assess The Effects Of Lunasin On Normal Development And Tumor Progression In Drosophila Melanogaster, Gillian E. Jones

Masters Theses & Specialist Projects

Soy contains many bioactive molecules known to elicit anti-cancer effects. One such peptide, Lunasin, has been shown to selectively act on newly transformed cells while having no cytotoxic effect on non-tumorigenic or established cancer cell lines. In this study we attempt to understand the developmental effects of Lunasin overexpression in vivo and create reagents that will help us understand Lunasin’s anti tumorigenic effects in an intact organism. cDNA encoding lunasin and EGFP-lunasin were cloned into pUAST and microinjected into Drosophila embryos. Tissue-specific overexpression of EGFP-Lun in the resulting transgenic lines was accomplished by crossing transgenics to various GAL4 driver lines. …
