Calpain Inhibitor Mdl28170 Modulates Abeta Formation By Inhibiting The Formation Of Intermediate Abeta46 And Protecting Abeta From Degradation, Y Dong, J Tan, Mei-Zhen Cui, G Zhao, G Mao, N Singh, Xuemin Xu

Mei-Zhen Cui

The observations that three major cleavages within the transmembrane domain of APP, namely, the gamma-cleavage, -cleavage, and the newly identified zeta-cleavage, are involved in the generation of secreted Abeta40 and Abeta42 prompted us to determine how the calpain inhibitor III MDL 28170 influences these three cleavages and Abeta formation. With the use of a cell culture system, our data demonstrate that 1) at either high concentrations, or at a low range of concentrations, at early time points, MDL 28170 inhibits the formation of secreted Abeta40 and Abeta42. However, this effect is due to inhibition of the intermediate Abeta46 generation by ...

PROCEDURES: Samples were first screened for FCoV via a reverse transcription-PCR procedure involving primers that encompassed the 3'-untranslated region. Samples that yielded positive assay results were analyzed by use of primers that targeted the 7a7b open reading frames. The nucleotide sequences of the 7a7b amplification products were ...


Pulmonary Fibroblasts Stimulate The Proliferation Of Cell Lines From Human Lung Adenocarcinomas, Maria Cekanova, T Masi, Howard Plummer, M Majidi, P Fedorocko, Hildegard Schuller Aug 2011

Pulmonary Fibroblasts Stimulate The Proliferation Of Cell Lines From Human Lung Adenocarcinomas, Maria Cekanova, T Masi, Howard Plummer, M Majidi, P Fedorocko, Hildegard Schuller

Howard K. Plummer III

Human lung cancer cell lines are widely used to test anticancer drugs. These in-vitro tests, however, preclude the detection of responses to paracrine factors from surrounding stroma. We have cocultured pulmonary fibroblasts CCD-19Lu, from a healthy donor, or HLF-A, from a patient with epidermoid carcinoma of the lung, with two human pulmonary adenocarcinoma cell lines to test the hypothesis that the fibroblasts stimulate the growth of the tumor cells. Both fibroblast cell lines significantly increased the proliferation of the pulmonary adenocarcinoma cell lines in 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyl tetrazolium bromide assays, with HLF-A fibroblasts yielding the most pronounced responses ...

Left-Right Olfactory Asymmetry Results From Antagonistic Functions Of Voltage-Activated Calcium Channels And The Raw Repeat Protein Olrn-1 In C. Elegans, S L. Bauer Haung, Y Saheki, Miri Vanhoven, I Torayama, T Ishihara, I Katsura, A Van Der Linden, P Sengupta, C I. Bargmann

Miri VanHoven

The left and right AWC olfactory neurons in Caenorhabditis elegans differ in their functions and in their expression of chemosensory receptor genes; in each animal, one AWC randomly takes on one identity, designated AWCOFF, and the contralateral AWC becomes AWCON. Signaling between AWC neurons induces left-right asymmetry through a gap junction network and a claudin-related protein, which inhibit a calcium-regulated MAP kinase pathway in the neuron that becomes AWCON. Results We show here that the asymmetry gene olrn-1 acts downstream of the gap junction and claudin genes to inhibit the calcium-MAP kinase pathway in AWCON. OLRN-1, a protein with potential ...

Genetics, Behavior And Ecology Of A Paper Wasp Invasion: Polistes Dominulus In North America, Aviva E. Liebert Dec 2006

Genetics, Behavior And Ecology Of A Paper Wasp Invasion: Polistes Dominulus In North America, Aviva E. Liebert

Biology Department Faculty Publications

Studies of social insect invasions to date have focused primarily on highly eusocial insects such as ants and yellowjacket wasps. Yet insect societies without fixed, morphological caste systems may be particularly good invaders due to their behavioral flexibility, as demonstrated by the recent invasion of the European paper wasp Polistes dominulus into North America. Here we provide a review of this ongoing invasion in terms of (1) population genetic variation in P. dominulus, and (2) comparative behavior and ecology of P. dominulus vs. the native P. fuscatus. We present new genetic evidence supporting the occurrence of multiple independent introductions of ...

Properties Of Corneal Receptors In A Teleost Fish, Paul J. Ashley, Lynne U. Sneddon, Catherine R. Mccrohan Dec 2006

Properties Of Corneal Receptors In A Teleost Fish, Paul J. Ashley, Lynne U. Sneddon, Catherine R. Mccrohan

VETERINARY SCIENCE AND MEDICINE

Corneal receptors have not previously been identified in lower vertebrates. The present study describes the properties of trigeminal ganglion corneal receptors in a teleost fish, the rainbow trout (Oncoryhnchus mykiss). Out of 27 receptors, 7 were polymodal nociceptors, 6 were mechanothermal nociceptors, 2 were mechanochemical receptors and the largest group, 12, were only responsive to mechanical stimulation. No cold responsive receptors were found on the trout cornea. Mechanical and thermal thresholds were lower and receptive field diameters smaller than those of cutaneous trigeminal receptors in the trout, demonstrating greater sensitivity in the cornea. The lack of cold sensitive neurons may ...

Untemplated Oligoadenylation Promotes Degradation Of Risc-Cleaved Transcripts, Fadia Ibrahim, Jennifer Rohr, Won-Joong Jeong, Jennifer Hesson, Heriberto D. Cerutti Dec 2006

Untemplated Oligoadenylation Promotes Degradation Of Risc-Cleaved Transcripts, Fadia Ibrahim, Jennifer Rohr, Won-Joong Jeong, Jennifer Hesson, Heriberto D. Cerutti

Faculty Publications from the Center for Plant Science Innovation

In the best-characterized mechanism of RNAmediated silencing, small interfering RNAs (siRNAs), incorporated into the RNA-induced silencing complex (RISC), guide the endonucleolytic cleavage of complementary RNAs (1). In Drosophila melanogaster, these RISC-generated products are eventually degraded by exoribonucleases: Xrn1, a 5′-to-3′ exonuclease, and exosome, a 3′-to-5′ multisubunit exonuclease (2). Interestingly, in Arabidopsis thaliana and in mammals, an oligouridine or oligoadenine [oligo(U/A)] tail is added to the 5′ RNA fragments resulting from microRNA-directed cleavage (3). However, the biological role of this tail remains unclear.


Activated Checkpoint Kinase 2 Provides A Survival Signal For Tumor Cells, Jagadish C. Ghosh, Takehiko Dohi, Christopher M. Raskett, Timothy F. Kowalik, Dario C. Altieri Dec 2006

Activated Checkpoint Kinase 2 Provides A Survival Signal For Tumor Cells, Jagadish C. Ghosh, Takehiko Dohi, Christopher M. Raskett, Timothy F. Kowalik, Dario C. Altieri

Open Access Articles

Tumor cells often become resistant to DNA damage-based therapy; however, the underlying mechanisms are not yet understood. Here, we show that tumor cells exposed to DNA damage counteract cell death by releasing the antiapoptotic protein, survivin, from mitochondria. This is independent of p53, and requires activated checkpoint kinase 2 (Chk2), a putative tumor suppressor. Molecular or genetic targeting of Chk2 prevents the release of survivin from mitochondria, enhances DNA damage-induced tumor cell apoptosis, and inhibits the growth of resistant in vivo tumors. Therefore, activated Chk2 circumvents its own tumor-suppressive functions by promoting tumor cell survival. Inhibiting Chk2 in combination with ...


The Health And Nutrition Of Migrant Farm Workers In South Carolina, Abel Caballero Dec 2006

The Health And Nutrition Of Migrant Farm Workers In South Carolina, Abel Caballero

All Theses

ABSTRACT
Migrant farm workers--a high percentage of which are Hispanic--are an extremely disadvantaged population that experiences several barriers, including language, nutrition, transportation, and access to health services. This population also suffers from numerous diseases (obesity, diabetes, and heart disease) and experiences various hazards associated with risky work, such as pesticide exposure. This study included data collection on basic health and nutrition barriers to identify areas where programs and policies can be modified to better serve migrant farm workers. In addition, data was examined to determine the effect of all-inclusive educational intervention on nutrition, dental, fitness, and food safety issues by ...


Spatial Variation In The Chemical Composition Of Natal Otholiths From A Reef Fish In The Galápagos Islands, Benjamin I. Ruttenberg, Robert R. Warner Dec 2006

Spatial Variation In The Chemical Composition Of Natal Otholiths From A Reef Fish In The Galápagos Islands, Benjamin I. Ruttenberg, Robert R. Warner

Biological Sciences

Over the past decade, researchers have used variation in the chemical composition of fish otoliths (earstones) to address a number of ecological questions, such as stock assessment and assessing rates of movement of individuals among habitats or life-history stages. However, these methods have yet to be applied successfully to the study of larval connectivity, a major unanswered question in marine ecology. Accomplishing this task requires a reference collection of pre-pelagic natal otoliths and accurate measurement of the chemical signatures of otoliths cores of recruits. We analyzed the chemical composition of natal otoliths from near-term benthic eggs of a damselfish (Stegastes ...


High Sensitivity Rna Pseudoknot Prediction, Xiaolu Huang, Hesham Ali Dec 2006

High Sensitivity Rna Pseudoknot Prediction, Xiaolu Huang, Hesham Ali

Information Systems and Quantitative Analysis Faculty Publications

Most ab initio pseudoknot predicting methods provide very few folding scenarios for a given RNA sequence and have low sensitivities. RNA researchers, in many cases, would rather sacrifice the specificity for a much higher sensitivity for pseudoknot detection. In this study, we introduce the Pseudoknot Local Motif Model and Dynamic Partner Sequence Stacking (PLMM_DPSS) algorithm which predicts all PLM model pseudoknots within an RNA sequence in a neighboring-region-interferencefree fashion. The PLM model is derived from the existing Pseudobase entries. The innovative DPSS approach calculates the optimally lowest stacking energy between two partner sequences. Combined with the Mfold, PLMM_DPSS can also ...


New Extension Corn Production Web Site, Lori Abendroth, Roger W. Elmore Dec 2006

New Extension Corn Production Web Site, Lori Abendroth, Roger W. Elmore

Integrated Crop Management News

We've designed a new Web site for Iowa State University Extension corn production that has current and relevant management information for producing corn in Iowa. The Web site provides research-based recommendations and diagnostic tools for producers and agribusinesses. The largest section of the Web site is devoted to "Corn Management," which is broken into categories based on whether the topic addresses overarching production issues, such as cropping systems and rotations, or if the topic can be isolated to a certain time of the growing season (planting, early-season, mid-/late-season, harvest). For example, in the "Planting" category, users can find ...
