Antimicrobial Peptides In 2014., Guangshun Wang, Biswajit Mishra, Kyle Lau, Tamara Lushnikova, Radha Golla, Xiuqing Wang

Journal Articles: Pathology and Microbiology

This article highlights new members, novel mechanisms of action, new functions, and interesting applications of antimicrobial peptides reported in 2014. As of December 2014, over 100 new peptides were registered into the Antimicrobial Peptide Database, increasing the total number of entries to 2493. Unique antimicrobial peptides have been identified from marine bacteria, fungi, and plants. Environmental conditions clearly influence peptide activity or function. Human α-defensin HD-6 is only antimicrobial under reduced conditions. The pH-dependent oligomerization of human cathelicidin LL-37 is linked to double-stranded RNA delivery to endosomes, where the acidic pH triggers the dissociation of the peptide aggregate to release …

Vigil, Yasir J. Sepah, Anthony L. Watters, Mohammad A. Sadiq, Mehreen Ansari, Millena G. Bittencourt, Mohamed A. Ibrahim, Diana V. Do, Quan Dong Nguyen

Journal Articles: Ophthalmology

BACKGROUND: The National Eye Institute 39-Question Visual Function Questionnaire (NEI VFQ-39) is an indicator of vision-related quality of life (QoL). The NEI VFQ-39 is used to assess the QoL in patients with non-infectious posterior uveitis, intermediate uveitis, or panuveitis, treated with subconjunctival (SCJ) or intravitreal (IVT) sirolimus as an immunomodulatory therapeutic (IMT) agent, delivered subconjunctivally (SCJ) or intravitreally (IVT) (the SAVE Study). Thirty subjects with non-infectious uveitis were randomized (SCJ:IVT, 1:1) for a prospective clinical trial. The 39-Question Visual Function Questionnaire (VFQ-39) was administered at baseline (BL), month 6 (M6), and month 12 (M12) visits. The survey measures self-reported vision …

Targeting Egf-Receptor(S) - Stat1 Axis Attenuates Tumor Growth And Metastasis Through Downregulation Of Muc4 Mucin In Human Pancreatic Cancer., Parthasarathy Seshacharyulu, Moorthy P. Ponnusamy, Satyanarayana Rachagani, Imayavaramban Lakshmanan, Dhanya Haridas, Y Yan, Apar Kishor Ganti, Surinder K. Batra

Journal Articles: Biochemistry & Molecular Biology

Transmembrane proteins MUC4, EGFR and HER2 are shown to be critical in invasion and metastasis of pancreatic cancer. Besides, we and others have demonstrated de novo expression of MUC4 in ~70-90% of pancreatic cancer patients and its stabilizing effects on HER2 downstream signaling in pancreatic cancer. Here, we found that use of canertinib or afatinib resulted in reduction of MUC4 and abrogation of in vitro and in vivo oncogenic functions of MUC4 in pancreatic cancer cells. Notably, silencing of EGFR family member in pancreatic cancer cells decreased MUC4 expression through reduced phospho-STAT1. Furthermore, canertinib and afatinib treatment also inhibited proliferation, …

Insertion Of Sequences At The Original Provirus Integration Site Of Mouse Rosa26 Locus Using The Crispr/Cas9 System., Rolen M. Quadros, Donald W. Harms, Masato Ohtsuka, Channabasavaiah B. Gurumurthy

Journal Articles: Genetics, Cell Biology & Anatomy

Targeted transgenic mouse models, where an exogenous gene is inserted into a specified genomic locus to achieve its stable and reliable expression, have been widely used in biomedical research. However, the available methodologies for targeted insertion of sequences require many laborious steps that involve the use of embryonic stem (ES) cells. We recently developed Pronuclear Injection-based Targeted Transgenesis (PITT), a method that uses a recombinase-mediated cassette exchange (RMCE) to enable insertion of sequences at a predetermined genomic locus, such as ROSA26. The PITT technique uses fertilized eggs (instead of ES cells) collected from 'seed mice' that contain the RMCE landing …

Prolonged-Acting, Multi-Targeting Gallium Nanoparticles Potently Inhibit Growth Of Both Hiv And Mycobacteria In Co-Infected Human Macrophages., Prabagaran Narayanasamy, Barbara L. Switzer, Bradley E. Britigan

Journal Articles: Pathology and Microbiology

Human immunodeficiency virus (HIV) infection and Mycobacterium tuberculosis (TB) are responsible for two of the major global human infectious diseases that result in significant morbidity, mortality and socioeconomic impact. Furthermore, severity and disease prevention of both infections is enhanced by co-infection. Parallel limitations also exist in access to effective drug therapy and the emergence of resistance. Furthermore, drug-drug interactions have proven problematic during treatment of co-incident HIV and TB infections. Thus, improvements in drug access and simplified treatment regimens are needed immediately. One of the key host cells infected by both HIV and TB is the mononuclear phagocyte (MP; monocyte, …

Inhibition Of Hedgehog Signaling Improves The Anti-Carcinogenic Effects Of Docetaxel In Prostate Cancer., Murielle Mimeault, Satyanarayana Rachagani, Sakthivel Muniyan, Parthasarathy Seshacharyulu, Sonny L. Johansson, Kkaustubh Datta, Ming-Fong Lin, Surinder K. Batra

Journal Articles: Biochemistry & Molecular Biology

The establishment of docetaxel-based chemotherapeutic treatments has improved the survival of castration-resistant prostate cancer (CRPC) patients. However, most patients develop resistance supporting the development of therapy. The current study was undertaken to establish the therapeutic benefit to target hedgehog signaling cascade using GDC-0449 to improve the efficacy of chemotherapeutic drug, docetaxel. Here, we show that the combination of GDC-0449 plus docetaxel inhibited the proliferation of WPE1-NB26 cells and PC3 cells via a blockade of G1 and G2M phases. The combined treatment significantly inhibited PC cell migration in vitro. Moreover, the apoptotic effect induced by GDC-0449 plus docetaxel on PC3 cells …

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is characterized by the frequent association of disease outside the lung. The objective of this study was to determine the presence of biomechanical gait abnormalities in COPD patients compared to healthy controls while well rested and without rest.

METHODS: Patients with COPD (N = 17) and aged-matched, healthy controls (N = 21) walked at their self-selected pace down a 10-meter walkway while biomechanical gait variables were collected. A one-minute rest was given between each of the five collected trials to prevent tiredness (REST condition). Patients with COPD then walked at a self-selected pace on …

Generation Of A Retinoblastoma (Rb)1-Inducible Dominant-Negative (Dn) Mouse Model., Shikha Tarang, Songila M.S.R Doi, Channabasavaiah B. Gurumurthy, Donald W. Harms, Rolen M. Quadros, Sonia M. Rocha-Sanchez

Journal Articles: Genetics, Cell Biology & Anatomy

Retinoblastoma 1 (Rb1) is an essential gene regulating cellular proliferation, differentiation, and homeostasis. To exert these functions, Rb1 is recruited and physically interacts with a growing variety of signaling pathways. While Rb1 does not appear to be ubiquitously expressed, its expression has been confirmed in a variety of hematopoietic and neuronal-derived cells, including the inner ear hair cells (HCs). Studies in transgenic mice demonstrate that complete germline or conditional Rb1 deletion leads to abnormal cell proliferation, followed by massive apoptosis; making it difficult to fully address Rb1's biochemical activities. To overcome these limitations, we developed a tetracycline-inducible TetO-CB-myc6-Rb1 (CBRb) mouse …

Amyloid Precursor-Like Protein 2 (Aplp2) Affects The Actin Cytoskeleton And Increases Pancreatic Cancer Growth And Metastasis., Poomy Pandey, Satyanarayana Rachagani, Srustidhar Das, Parthasarathy Seshacharyulu, Yuri Sheinin, Naava Naslavsky, Zenggang Pan, Brittney L. Smith, Haley L. Peters, Prakash Radhakrishnan, Nicole R. Mckenna, Sai Srinivas Panapakkam Giridharan, Dhanya Haridas, Sukhwinder Kaur, Michael A. Hollingsworth, Richard G. Macdonald, Jane L. Meza, Steve Caplan, Surinder K. Batra, Joyce C. Solheim

Journal Articles: Biochemistry & Molecular Biology

Amyloid precursor-like protein 2 (APLP2) is aberrantly expressed in pancreatic cancer. Here we showed that APLP2 is increased in pancreatic cancer metastases, particularly in metastatic lesions found in the diaphragm and intestine. Examination of matched human primary tumor-liver metastasis pairs showed that 38.1% of the patients had positive APLP2 expression in both the primary tumor and the corresponding liver metastasis. Stable knock-down of APLP2 expression (with inducible shRNA) in pancreatic cancer cells reduced the ability of these cells to migrate and invade. Loss of APLP2 decreased cortical actin and increased intracellular actin filaments in pancreatic cancer cells. Down-regulation of APLP2 …

Overview Of Microrna Biology, Ashley M. Mohr, Justin L. Mott

Journal Articles: Biochemistry & Molecular Biology

In considering an overview of microRNA biology, it is useful to consider microRNAs as a part of cellular communication. At the simplest level, microRNAs act to decrease the expression of mRNAs that contain stretches of sequence complementary to the microRNA. This function can be likened to the function of endogenous or synthetic short interfering RNA (siRNA). However, microRNA function is more complicated and nuanced than this ‘on-off’ model would suggest. Further, many microRNA targets are themselves non-coding RNAs. In this review, we will discuss the role of microRNAs in shaping the proteome of the cell in a way that is …

Impact Of A High-Fat Meal On Assessment Of Clopidogrel-Induced Platelet Inhibition In Healthy Subjects., Paul P. Dobesh, Jamela F. Urban, Scott W. Shurmur, Julie H. Oestreich

Journal Articles: Pharmacy Practice

BACKGROUND: Ideal conditions for platelet reactivity testing are critical for optimal selection of a P2Y12 inhibitor. Data are inconsistent regarding the impact of high-fat meals on test assessment.

METHODS: Participants included 12 healthy subjects not taking antiplatelet drugs after a 12-hour fast. After baseline assessment, subjects were given a 600 mg dose of clopidogrel. Four hours later, maximum platelet inhibition was tested in the fasting state by light transmission aggregometry (LTA), VerifyNow P2Y12, vasodilator-stimulated phosphoprotein (VASP), and whole blood aggregometry (WBA). Subjects were then provided a high-fat meal, and platelet function was evaluated two hours later. Change in measured platelet …

Opposing Regulation Of Endolysosomal Pathways By Long-Acting Nanoformulated Antiretroviral Therapy And Hiv-1 In Human Macrophages., Mariluz Araínga, Dongwei Guo, Jayme Wiederin, Pawel Ciborowski, Joellyn Mcmillan, Howard Gendelman

Journal Articles: Pharmacology & Experimental Neuroscience

BACKGROUND: Long-acting nanoformulated antiretroviral therapy (nanoART) is designed to improve patient regimen adherence, reduce systemic drug toxicities, and facilitate clearance of human immunodeficiency virus type one (HIV-1) infection. While nanoART establishes drug depots within recycling and late monocyte-macrophage endosomes, whether or not this provides a strategic advantage towards viral elimination has not been elucidated.

RESULTS: We applied quantitative SWATH-MS proteomics and cell profiling to nanoparticle atazanavir (nanoATV)-treated and HIV-1 infected human monocyte-derived macrophages (MDM). Native ATV and uninfected cells served as controls. Both HIV-1 and nanoATV engaged endolysosomal trafficking for assembly and depot formation, respectively. Notably, the pathways were deregulated …

Bridged Filaments Of Histone-Like Nucleoid Structuring Protein Pause Rna Polymerase And Aid Termination In Bacteria., Matthew V. Kotlajich, Daniel R. Hron, Beth A. Boudreau, Zhiqiang Sun, Yuri L. Lyubchenko, Robert Landick

Journal Articles: Pharmaceutical Sciences

Bacterial H-NS forms nucleoprotein filaments that spread on DNA and bridge distant DNA sites. H-NS filaments co-localize with sites of Rho-dependent termination in Escherichia coli, but their direct effects on transcriptional pausing and termination are untested. In this study, we report that bridged H-NS filaments strongly increase pausing by E. coli RNA polymerase at a subset of pause sites with high potential for backtracking. Bridged but not linear H-NS filaments promoted Rho-dependent termination by increasing pause dwell times and the kinetic window for Rho action. By observing single H-NS filaments and elongating RNA polymerase molecules using atomic force microscopy, we …

130 Years Of Leadership: Images Of The Deans Of The College Of Medicine 1881-2010, Robert Wigton

130 Years of Leadership: Images of the Deans of the College of Medicine 1881-2010

When I joined the College of Medicine faculty, I became interested in the photographs of previous deans of the college displayed on a conference room wall. There was no information, however, about any of the deans and I was curious about their careers and accomplishments. Much later I began this project to research each of them, find a photo from the time they were dean, write a concise biography, and add a photo representative of the college during that era. What I found was a distinguished group of scholars, many of whom, even in the early years, were highly regarded …

Motor-Skill Learning Is Dependent On Astrocytic Activity., Ragunathan Padmashri, Anand Suresh, Michael D. Boska, Anna Dunaevsky

Journal Articles: Munroe-Meyer Institute

Motor-skill learning induces changes in synaptic structure and function in the primary motor cortex through the involvement of a long-term potentiation- (LTP-) like mechanism. Although there is evidence that calcium-dependent release of gliotransmitters by astrocytes plays an important role in synaptic transmission and plasticity, the role of astrocytes in motor-skill learning is not known. To test the hypothesis that astrocytic activity is necessary for motor-skill learning, we perturbed astrocytic function using pharmacological and genetic approaches. We find that perturbation of astrocytes either by selectively attenuating IP3R2 mediated astrocyte Ca(2+) signaling or using an astrocyte specific metabolic inhibitor fluorocitrate (FC) results …

Validation Of Simple Sequence Length Polymorphism Regions Of Commonly Used Mouse Strains For Marker Assisted Speed Congenics Screening., Channabasavaiah B. Gurumurthy, Poonam S. Joshi, Scott G. Kurz, Masato Ohtsuka, Rolen M. Quadros, Donald W. Harms, K.C. Kent Lloyd

Journal Articles: Genetics, Cell Biology & Anatomy

Marker assisted speed congenics technique is commonly used to facilitate backcrossing of mouse strains in nearly half the time it normally takes otherwise. Traditionally, the technique is performed by analyzing PCR amplified regions of simple sequence length polymorphism (SSLP) markers between the recipient and donor strains: offspring with the highest number of markers showing the recipient genome across all chromosomes is chosen for the next generation. Although there are well-defined panels of SSLP makers established between certain pairs of mice strains, they are incomplete for most strains. The availability of well-established marker sets for speed congenic screens would enable the …

Assessment Of Artificial Mirna Architectures For Higher Knockdown Efficiencies Without The Undesired Effects In Mice., Hiromi Miura, Hidetoshi Inoko, Masafumi Tanaka, Hirofumi Nakaoka, Minoru Kimura, Channabasavaiah B. Gurumurthy, Masahiro Sato, Masato Ohtsuka

Journal Articles: Genetics, Cell Biology & Anatomy

RNAi-based strategies have been used for hypomorphic analyses. However, there are technical challenges to achieve robust, reproducible knockdown effect. Here we examined the artificial microRNA (amiRNA) architectures that could provide higher knockdown efficiencies. Using transient and stable transfection assays in cells, we found that simple amiRNA-expression cassettes, that did not contain a marker gene (-MG), displayed higher amiRNA expression and more efficient knockdown than those that contained a marker gene (+MG). Further, we tested this phenomenon in vivo, by analyzing amiRNA-expressing mice that were produced by the pronuclear injection-based targeted transgenesis (PITT) method. While we observed significant silencing of the …

De Novo Assembly Of The Chimpanzee Transcriptome From Nextgen Mrna Sequences, Mnirnal D. Maudhoo, Jacob D. Madison, Robert B. Norgren

Journal Articles: Genetics, Cell Biology & Anatomy

BACKGROUND: Common chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) are the species most closely related to humans. For this reason, it is especially important to have complete and accurate chimpanzee nucleotide and protein sequences to understand how humans evolved their unique capabilities. We provide transcriptome data from four untransformed cell types derived from the reference Pan troglodytes, "Clint", to better annotate the chimpanzee genome and provide empirical validation for proposed gene models of this important species.

FINDINGS: RNA was extracted from primary cells cultured from four tissues: skin, adipose stroma, vascular smooth muscle and skeletal muscle. These four RNA samples …

Gentamicin Differentially Alters Cellular Metabolism Of Cochlear Hair Cells As Revealed By Nad(P)H Fluorescence Lifetime Imaging, Lyandysha V. Zholudeva, Kristina G. Ward, Michael G. Nichols, Heather Jensen Smith

Journal Articles: Eppley Institute

Aminoglycoside antibiotics are implicated as culprits of hearing loss in more than 120,000 individuals annually. Research has shown that the sensory cells, but not supporting cells, of the cochlea are readily damaged and/or lost after use of such antibiotics. High-frequency outer hair cells (OHCs) show a greater sensitivity to antibiotics than high- and low-frequency inner hair cells (IHCs). We hypothesize that variations in mitochondrial metabolism account for differences in susceptibility. Fluorescence lifetime microscopy was used to quantify changes in NAD(P)H in sensory and supporting cells from explanted murine cochleae exposed to mitochondrial uncouplers, inhibitors, and an ototoxic antibiotic, gentamicin (GM). …
