Differential Effect Of 14 Free Fatty Acids In The Expression Of Inflammation Biomarkers On Human Coronary Arterial Cells, Adriana Soto Rodriguez Gil Jan 2013

Differential Effect Of 14 Free Fatty Acids In The Expression Of Inflammation Biomarkers On Human Coronary Arterial Cells, Adriana Soto Rodriguez Gil

LSU Master's Theses

Cardiovascular disease is the leading cause of death in the US, and circulating free fatty acids (FFAs) are known risk factors associated with cardiovascular inflammation. The influence of 14 dietary FFAs (including saturated, mono-, poly-unsaturated and trans), on the expression of inflammatory markers in human coronary arterial smooth muscle (HACSM) and endothelial (HCAEC) cells using a cell culture model was investigated. HACSM and HCAEC cell cultures were incubated with 200 μM of each FFA for 8 or 24 h respectively at 37 °C in a 5% CO2 humidified incubator. Inflammatory biomarkers were assessed by ELISA or Western Blot in the …

Faculty Senate Newsletter, Holiday 2012, Louisiana State University And Agricultural & Mechanical College

LSU Faculty Senate Publications

Message from President: Whatever else it may connote, the Christmas season is about hope—about illumination during the darkest days of the year. Although it now basks in the highly refracted light of infamy, having been spanked by Louisiana’s Attorney General and having drawn reproaches from SACSCOC accreditors, the LSU System has, in the past, enjoyed more than a few Star-of-Bethlehem moments. When the University of Louisiana System diluted tenure guarantees, for example, the LSU System garnered applause for its flagship-quality approach to this foundation of academic freedom; when the Southern University System lurched into financial exigency, the LSU System glimmered …

Social Information Changes The Brain, Russell D. Fernald, Karen P. Maruska Oct 2012

Social Information Changes The Brain, Russell D. Fernald, Karen P. Maruska

Faculty Publications

Social animals live in complex physical and social environments requiring them to attend and rapidly respond to social and environmental information by changing their behavior. A key social influence is rank or status, a ubiquitous element in animal societies. Rank typically regulates access to reproduction and other resources, among other consequences for individuals. Because reproduction is arguably the most important event in any animals' life, understanding howreproduction is regulated by social status and related physiological factors can instruct our understanding of evolutionary change. This article reviews evidence from a model social system in which reproduction is tightly controlled by social …

Cytokinesis-Based Constraints On Polarized Cell Growth In Fission Yeast, K. Adam Bohnert, Kathleen L. Gould Oct 2012

Cytokinesis-Based Constraints On Polarized Cell Growth In Fission Yeast, K. Adam Bohnert, Kathleen L. Gould

Faculty Publications

The rod-shaped fission yeast Schizosaccharomyces pombe, which undergoes cycles of monopolar-to-bipolar tip growth, is an attractive organism for studying cell-cycle regulation of polarity establishment. While previous research has described factors mediating this process from interphase cell tips, we found that division site signaling also impacts the re-establishment of bipolar cell growth in the ensuing cell cycle. Complete loss or targeted disruption of the non-essential cytokinesis protein Fic1 at the division site, but not at interphase cell tips, resulted in many cells failing to grow at new ends created by cell division. This appeared due to faulty disassembly and abnormal persistence …

Tfiiic Localizes Budding Yeast Etc Sites To The Nuclear Periphery, Shin Ichiro Hiraga, Sotirios Botsios, David Donze, Anne D. Donaldson Jul 2012

Tfiiic Localizes Budding Yeast Etc Sites To The Nuclear Periphery, Shin Ichiro Hiraga, Sotirios Botsios, David Donze, Anne D. Donaldson

Faculty Publications

Chromatin function requires specific three-dimensional architectures of chromosomes. We investigated whether Saccharomyces cerevisiae extra TFIIIC (ETC) sites, which bind the TFIIIC transcription factor but do not recruit RNA polymerase III, show specific intranuclear positioning. We show that six of the eight known S. cerevisiae ETC sites localize predominantly at the nuclear periphery, and that ETC sites retain their tethering function when moved to a new chromosomal location. Several lines of evidence indicate that TFIIIC is central to the ETC peripheral localization mechanism. Mutating or deleting the TFIIIC-binding consensus ablated ETC -site peripheral positioning, and inducing degradation of the TFIIIC subunit …

Controlling A Master Switch Of Adipocyte Development And Insulin Sensitivity: Covalent Modifications Of Pparγ, Z. Elizabeth Floyd, Jacqueline M. Stephens Jul 2012

Controlling A Master Switch Of Adipocyte Development And Insulin Sensitivity: Covalent Modifications Of Pparγ, Z. Elizabeth Floyd, Jacqueline M. Stephens

Faculty Publications

Adipocytes are highly specialized cells that play a central role in lipid homeostasis and the maintenance of energy balance. Obesity, an excessive accumulation of adipose tissue, is a major risk factor for the development of Type 2 diabetes mellitus (T2DM), cardiovascular disease, and hypertension. A variety of studies suggest that obesity and T2DM can be linked to a breakdown in the regulatory mechanisms that control the expression and transcriptional activity of PPARγ. PPARγ is a nuclear hormone receptor that functions as a master switch in controlling adipocyte differentiation and development. Also important in controlling glucose homeostasis and insulin sensitivity, PPARγ …

Ecology And Management Of Bark Beetles (Coleoptera: Curculionidae: Scolytinae) In Southern Pine Forests, T. D. Schowalter Jun 2012

Ecology And Management Of Bark Beetles (Coleoptera: Curculionidae: Scolytinae) In Southern Pine Forests, T. D. Schowalter

Faculty Publications

Bark beetles (Coleoptera: Curculionidae: Scolytinae) have been an important historic and current factor affecting pine forest production in the southern United States. Although tree mortality to bark beetles often detracts from forest management goals, the natural role of bark beetles is canopy opening, thinning, and diversification of stand structure and composition, effects that contribute to some ecosystem services in forests managed for multiple uses. Strategies to prevent bark beetle outbreaks exploit their sensitivity to host tree spacing and reliance on pheromones to attract sufficient numbers to overwhelm tree defenses. Tree species selection at planting or through selective thinning can favor …

Costs And Benefits Of Jasmonic Acid Induced Responses In Soybean, A. K. Accamando, J. T. Cronin Jun 2012

Costs And Benefits Of Jasmonic Acid Induced Responses In Soybean, A. K. Accamando, J. T. Cronin

Faculty Publications

In response to herbivory, plants have evolved defense strategies to reduce herbivore preference and performance. A strategy whereby defenses are induced only upon herbivory can mitigate costs of defense when herbivores are scarce. Although costs and benefits of induced responses are generally assumed, empirical evidence for many species is lacking. Soybean (Glycine max L. Merr.) has emerged as a model species with which to address questions about induced responses. To our knowledge, this is the first study to examine the fitness costs and benefits of jasmonic acid-induced responses by soybean in the absence and presence of soybean loopers (Chrysodeix includens …

Exploring Post-Translational Arginine Modification Using Chemically Synthesized Methylglyoxal Hydroimidazolones, Tina Wang, Rendy Kartika, David A. Spiegel May 2012

Exploring Post-Translational Arginine Modification Using Chemically Synthesized Methylglyoxal Hydroimidazolones, Tina Wang, Rendy Kartika, David A. Spiegel

Faculty Publications

The methylglyoxal-derived hydroimidazolones (MG-Hs) comprise the most prevalent class of non-enzymatic, post-translational modifications of protein arginine residues found in nature. These adducts form spontaneously in the human body, and are also present at high levels in the human diet. Despite numerous lines of evidence suggesting that MG-H-arginine adducts play critical roles in both healthy and disease physiology in humans, detailed studies of these molecules have been hindered by a lack of general synthetic strategies for their preparation in chemically homogeneous form, and on scales sufficient to enable detailed biochemical and cellular investigations. To address this limitation, we have developed efficient, …

Angiogenic Deficiency And Adipose Tissue Dysfunction Are Associated With Macrophage Malfunction In Sirt1 -/- Mice, Fen Xu, David Burk, Zhanguo Gao, Jun Yin, Xia Zhang, Jianping Weng, Jianping Ye

Faculty Publications

The histone deacetylase sirtuin 1 (SIRT1) inhibits adipocyte differentiation and suppresses inflammation by targeting the transcription factors peroxisome proliferator-activated receptor γ and nuclear factor κB. Although this suggests that adiposity and inflammation should be enhanced when SIRT1 activity is inactivated in the body, this hypothesis has not been tested in SIRT1 null (SIRT1 -/-) mice. In this study, we addressed this issue by investigating the adipose tissue in SIRT1 -/-mice. Compared with their wild-type littermates, SIRT1 null mice exhibited a significant reduction in body weight. In adipose tissue, the average size of adipocytes was smaller, the content of extracellular matrix …
