Modulation Of Yeast Genome Expression In Response To Defective Rna Polymerase Iii-Dependent Transcription, Christine Conesa, Roberta Ruotolo, Pascal Soularue, Tiffany A. Simms, David Donze, André Sentenac, Giorgio Dieci

Faculty Publications

We used genome-wide expression analysis in Saccharomyces cerevisiae to explore whether and how the expression of protein-coding, RNA polymerase (Pol) II-transcribed genes is influenced by a decrease in RNA Pol III-dependent transcription. The Pol II transcriptome was characterized in four thermosensitive, slow-growth mutants affected in different components of the RNA Pol III transcription machinery. Unexpectedly, we found only a modest correlation between altered expression of Pol II-transcribed genes and their proximity to class III genes, a result also confirmed by the analysis of single tRNA gene deletants. Instead, the transcriptome of all of the four mutants was characterized by increased …

Faculty Publications

Directional transport of the phytohormone auxin is required for the establishment and maintenance of plant polarity, but the underlying molecular mechanisms have not been fully elucidated. Plant homologs of human multiple drug resistance/P-glycoproteins (MDR/PGPs) have been implicated in auxin transport, as defects in MDR1 (AtPGP19) and AtPGP1 result in reductions of growth and auxin transport in Arabidopsis (atpgp1, atpgp19), maize (brachytic2) and sorghum (dwarf3). Here we examine the localization, activity, substrate specificity and inhibitor sensitivity of AtPGP1. AtPGP1 exhibits non-polar plasma membrane localization at the shoot and root apices, as well as polar localization above the root apex. Protoplasts from …

Highly Water-Soluble Thermally Responsive Poly(Thiophene)-Based Brushes, Sreelatha S. Balamurugan, Grigor B. Bantchev, Yuming Yang, Robin L. Mccarley

Faculty Publications

(Figure Presented) A brush with success: Responsive brushes composed of poly(N-isopropylacrylamide) grafted onto a poly(thiophene) backbone display the highest water solubility ever reported for a neutral poly(thiophene) as well as temperature-dependent optical properties and water solubilities (see picture). The graft polymer exhibits shifts in the π-π* transition of the poly(thiophene) backbone near the collapse temperature of the poly(N-isopropylacrylamide) chains. © 2005 Wiley-VCH Verlag GmbH & Co.

Altering The Tropism Of Lentiviral Vectors Through Pseudotyping, James Cronin, Xian Yang Zhang, Jakob Reiser

Faculty Publications

The host range of retroviral vectors including lentiviral vectors can be expanded or altered by a process known as pseudotyping. Pseudotyped lentiviral vectors consist of vector particles bearing glycoproteins (GPs) derived from other enveloped viruses. Such particles possess the tropism of the virus from which the GP was derived. For example, to exploit the natural neural tropism of rabies virus, vectors designed to target the central nervous system have been pseudotyped using rabies virus-derived GPs. Among the first and still most widely used GPs for pseudotyping lentiviral vectors is the vesicular stomatitis virus GP (VSV-G), due to the very broad …

Enhancement Of Calcium-Dependent Afterpotentials In Oxytocin Neurons Of The Rat Supraoptic Nucleus During Lactation, Ryoichi Teruyama, William E. Armstrong

Faculty Publications

The firing pattern of oxytocin (OT) hormone synthesizing neurons changes dramatically immediately before each milk ejection, when a brief burst of action potentials is discharged. OT neurons possess intrinsic currents that would modulate this burst. Our previous studies showed the amplitude of the Ca2+-dependent afterhyperpolarization (AHP) following spike trains is significantly larger during lactation. In the present study we sought to determine which component of the AHP is enhanced, and whether the enhancement could be related to changes in whole-cell Ca2+ current or the Ca2+ transient in identified OT or vasopressin (VP) neurons during lactation. We confirmed, with whole-cell current-clamp …

Effects Of Leukemia Inhibitory Factor On 3t3-L1 Adipocytes, Jessica C. Hogan, Jacqueline M. Stephens

Faculty Publications

Leukemia inhibitory factor (LIF) is a member of the gp130 cytokine family and signals through the receptor complex of gp130 and the LIF receptor (LIFR) to activate the JAK/STAT signaling cascade. Since LIF activates STATs 1 and 3 in adipocytes, we examined the effects of LIF on 3T3-L1 adipocytes. Our studies clearly demonstrate that LIF treatment had minimal effects on adipocyte differentiation as judged by marker gene expression, but did inhibit triacylglyceride (TAG) accumulation during adipogenesis. Acute treatment with LIF resulted in increased expression of suppressors of cytokine signaling-3 (SOCS3) and CCAAT/enhancer-binding protein-δ (C/EBPδ) mRNA in 3T3-L1 adipocytes. Moreover, the …

Subzero Water Permeability Parameters And Optimal Freezing Rates For Sperm Cells Of The Southern Platyfish, Xiphophorus Maculatus, D. Pinisetty, C. Huang, Q. Dong, T. R. Tiersch, R. V. Devireddy

Faculty Publications

This study reports the subzero water transport characteristics (and empirically determined optimal rates for freezing) of sperm cells of live-bearing fishes of the genus Xiphophorus, specifically those of the southern platyfish Xiphophorus maculatus. These fishes are valuable models for biomedical research and are commercially raised as ornamental fish for use in aquariums. Water transport during freezing of X. maculatus sperm cell suspensions was obtained using a shape-independent differential scanning calorimeter technique in the presence of extracellular ice at a cooling rate of 20°C/min in three different media: (1) Hanks' balanced salt solution (HBSS) without cryoprotective agents (CPAs); (2) HBSS with …

Alu Retrotransposition-Mediated Deletion, Pauline A. Callinan, Jianxin Wang, Scott W. Herke, Randall K. Garber, Ping Liang, Mark A. Batzer

Faculty Publications

Alu repeats contribute to genomic instability in primates via insertional and recombinational mutagenesis. Here, we report an analysis of Alu element-induced genomic instability through a novel mechanism termed retrotransposition-mediated deletion, and assess its impact on the integrity of primate genomes. For human and chimpanzee genomes, we find evidence of 33 retrotransposition-mediated deletion events that have eliminated approximately 9000 nucleotides of genomic DNA. Our data suggest that, during the course of primate evolution, Alu retrotransposition may have contributed to over 3000 deletion events, eliminating approximately 900 kb of DNA in the process. Potential mechanisms for the creation of Alu retrotransposition-mediated deletions …

High-Frequency Phase Variation Of Vibrio Vulnificus 1003: Isolation And Characterization Of A Rugose Phenotypic Variant, Brenda L. Grau, Margaret C. Henk, Gregg S. Pettis

Faculty Publications

The marine bacterium Vibrio vulnificus is a human pathogen that can spontaneously switch between virulent opaque and avirulent translucent phenotypes. Here, we document an additional form, the rugose variant, which produces copious biofilms and which may contribute both to pathogenicity of V. vulnificus and to its survival under adverse environmental conditions.

Polymerized Oligopeptide-Surfactant Chiral Micelles, Isiah M. Warner, Eugene J. Billiot, Shahab A. Shamsi, Stefan J. Thibodeaux

College of Science Patents

Chiral separations can be enhanced through the use of polymerized dipeptide-surfactant or oligopeptide-surfactant chiral micelles. Because polymerized micelles eliminate much of the complex dynamic behavior associated with conventional micelles, polymerized chiral micelles have stronger chiral recognition properties than do otherwise-identical, “conventional” or non-polymerized chiral micelles. Recovery of chiral ligands from polymerized chiral micelles is often easier, as the chiral ligands may typically be recovered by simple extraction with an appropriate organic solvent. By contrast, recovering the solute from a conventional, non-polymerized micellar medium by extraction with an organic solvent frequently results in the formation of troublesome emulsion systems. Polymerized chiral …

Amplitude And Phase Control Of Attosecond Light Pulses, Rodrigo López-Martens, Katalin Varjú, Per Johnsson, Johan Mauritsson, Yann Mairesse, Pascal Salières, Mette B. Gaarde, Kenneth J. Schafer, Anders Persson, Sune Svanberg, Claes Göran Wahlström, Anne L'Huillier

Faculty Publications

We report the generation, compression, and delivery on target of ultrashort extreme-ultraviolet light pulses using external amplitude and phase control. Broadband harmonic radiation is first generated by focusing an infrared laser with a carefully chosen intensity into a gas cell containing argon atoms. The emitted light then goes through a hard aperture and a thin aluminum filter that selects a 30-eV bandwidth around a 30-eV photon energy and synchronizes all of the components, thereby enabling the formation of a train of almost Fourier-transform-limited single-cycle 170 attosecond pulses. Our experiment demonstrates a practical method for synthesizing and controlling attosecond waveforms. © …
